Last week GM vice-chairman wrote a blog post giving his first hand experience driving one of the latest Volt mules. These mules use a Chevy Cruze shell, but sit atop the same global compact delta platform the Volt will and use all internal Chevy Volt production-intent parts.
Many readers picked up on this comment he wrote:
“We started with about a 60-percent charge on the battery pack, to see how it would perform and when the engine would kick on,” and “to my delight, we went about 19 silent, electrically powered miles before that engine engaged.”
This led some of us to wonder exactly what he meant by the 60-percent charge.
I had the chance to ask him directly and got even more in return:
When you said the car was at 60% charge when you started did you mean 60% State of Charge or 60% of the way from depletion (30%) to 80% SOC?
Mr. Lutz’ reply:
“It was 60% of the 80% max-30% min band. That’s why I was so delighted that it went over 20 miles in cold weather and at 65 mph or more, steady-state! ”
So now we know for the first time how the Volt prototypes are using battery energy at steady-state highway speed and presumably heating the passenger cabin on a sub-freezing day.
Two points are worth mentioning. It turned out 4.8 kwh was used to go the 19 to 20 or so miles. Also these prototypes would be less efficient than production Volts due to the unrefined nature of prototypes and the fact that Cruze shells would be less aerodynamic than Volt shells.
Now let’s hear what you think!

Dec 1st, 2008 (12:42 am)I’m assuming here that the Volt will always display “% charge” as being within that 30 to 80% SOC “window”. This would imply that as a new car my “0-100% Charge” would have a lot of margin within the batteries’ actual storage capacity.
As the car and battery aged, however, the same “0-100% Charge” would still give me the same range, but by “end of life”, the batteries actual storage capacity would have decreased to the point that the “reported Charge” now represents the batteries’ actual capability?
>>In other words, I expect the Volt will under-estimate it’s range ability during it’s first few years in order to best preserve battery capacity and user confidence – and then degrade “gracefully” after that.
– What do you think?

Dec 1st, 2008 (12:55 am)was just reading about this guy who converted his car to electric himself and added a briggs and stratton lawnmover engine to the equation and gets 75 MPG!!! crazy, got me thinking, if this guy can buil this himself for $1500, wonder what i can build?
What’s his secret? Well, Dave’s Opel CT is a hybrid electric vehicle. That is, the car is driven by an electric motor . . . but that powerplant’s “juice” is generated with the help of an ordinary, fuel-stingy lawn-mower engine! Now the fact that the system works isn’t really surprising. What’s amazing is that the crossbreed hookup performs so well! According to David, the Opel has not only a virtually unlimited range (when driven prudently), but also a top speed of 90 miles per hour . . . and emits a minimum of pollutants as it tools along the highway. Better yet, the car can-if need be-run on its batteries alone for short in-town hops . . . and will never be “stranded” as long as there’s fuel in the “on board” generator!
“I began researching the idea for a hybrid electric auto about a year ago. There wasn’t much information to be found on the subject, so I designed a system from scratch. In about a month’s evening-and-weekend time, I had the car finished and running.”
HOW IT WORKS
In essence, David has utilized a small gas lawn-mower engine to drive a generator, which-in turn-supplies the vehicle’s drive motor with electricity. To do so, he first removed the Opel’s original power-plant and installed a 400-amp DC motor/ generator (actually a jet engine’s starting motor) in its place. (Since there’s no need for a clutch in Dave’s setup, the stock unit was pulled out and the main shaft of the drive motor was fastened directly to the input shaft of the car’s transmission.) Then, to provide a consistent source of power for this motor (and to supply an energy storage bank), the engineer installed four 12-volt, heavy-duty automobile batteries-in series-which are “fed” by a 100-amp generator that’s run off a 5-horsepower lawn-mower engine.

It’s possible that the Volt, in warm weather, might be able to go 35 or so miles in a driving style approaching US 06. That would be a very pleasant surprise because the thinking has been the range with that driving style would be more like 28 miles.
We’ll just have to see what the final numbers are like. But this is great news.

Dec 1st, 2008 (3:19 am)O.K. – Lutz said “about 19 silent miles” in his first comment, then when asked for clarification he said “it went over 20 miles”. So if it goes 20 miles on a 60% charge (the charge they left in the battery available for gas free travel) then on a 100% charge you would expect the remaining 40% to take them another 40/60 times 20 miles or another 13.32 miles? That gives a range of 33.32 miles, not 40. So what gives? What am I forgetting?

Dec 1st, 2008 (3:57 am)To be fair, I would expect heating and air conditioning to use up some of the available electric energy planned for the 40 miles. But GM should have turned the heater off so they could get a good idea from this initial test report and public announcement. Sounds like they are cutting it too close. Hey, I want to see this electric car succeed too! But GM must eliiminate all suspicions that they are fudging numbers to make it appear all is well. If the battery is marginal, then increase the limits between max and min charge slightly to compensate. Or do they KNOW such a small modification would cut into battery promised/guaranteed life? We hear you Aussies – delighted that you would be good customers. I understand you don’t have the appetite for heat and air-conditioning that we softies in the US do! Perhaps it has something to do with your temperate climate.
(Quote)
Dec 1st, 2008 (4:07 am)“it went over 20 miles in cold weather”
“presumably heating the passenger cabin” or not, wouldn’t it be better to put in a webasto-type diesel or petrol heater instead of taking it from the batteries? Burning fuel for direct heating gives nearly 100% efficiency. Much (most?) of the electricity stored in the batteries will be produced from fossile with far less efficiency, not to mention if using the batteries to heat means you will have to switch to engine to get home. So installing a webasto will make this car even ‘greener’ (unless you accept extra clothing or freezing).

Dec 1st, 2008 (4:47 am)Not to be Mr Negative, but the Volt is going to fail for there are very few idiots among us that will plop down $40,000 for a car which will (perhaps) obtain 40 miles under full, quiet electric power after which the 1.4 liter ICE will kick in to extend the range. One little tidbit – who is going to want to drive 42 miles, then sit at a stop light while the ICE runs at 3500 RPM to recharge the batteries?? No one ever talks about that little bugaboo. I drive a 100% electric car each and every day and I can tell you that the average American citizen is not going to embrace giving up their SUVs and such for small EV – we’re all to damn selfish.

30°F is not cold. In fact, that’s pretty warm by Minnesota standards.
It’s also warm by hybrid measure. Efficiency doesn’t take the heavy hit until the temperature drops much lower.
(Quote)
Dec 1st, 2008 (4:58 am)One thing to consider is that this test was at 65 mph in a “mule”, not an actual Volt body. I would suspect that the smaller Volt body would have lower wind resistance than the mule, and therefore the actual Volt body would have gone more miles with the 60% charge. All they needed was 24 miles instead of 19 miles on the 60% charge, and they would have the 40 miles promised.
Yes, having the heater running would reduce the range. I haven’t heard how the heater is going to work in the Volt. My factory built 1998 Chevy S10-EV uses two heaters–above 40F it uses the air conditioner in reverse (as a heat pump), and it consumes about 1.5 KW while operating. Below 40F it switches to a kerosine/diesel fuel heater (I use about 5 gallons of kerosine in a Chicago winter).
If the Volt uses a heat pump like my S10-EV and it consumes the same power, then running 19 miles at 65 mph would take 18 minutes, and it would consume .45 KWH of battery power in that time. If the Volt’s battery has 10KWH of usable energy, the heater would have consumed 4.5% of the electric range during that 18 minutes, or about 2 miles. So the car would have gone 21 miles instead of 19 miles, had the heater not been running. (again, assuming the same heat pump as is in my vehicle)
Has anyone heard what the Volt is going to use for a heating system?

Finally, I wish GM would quit trying to greenwash their hybrid Escalante and its fat sister as green vehicles. They used up lots of resources to build, they take up too much room on the road, and they can badly damage reasonably-sized vehicles.

The volt has been no different. First the body changes. now the less than stellar driving distances… We want real word Distances, that means with the AC/Heat running, or the windows down, Radio Playing, passenger and some gear. On real roads with real traffic not some test track were you can set the cruise and glide along.
I don’t know how many commutes are steady state 65 mph…I know mine isn’t. I go 18 miles and it takes me on average 30 minutes to work and 45 going home…
The question now, is if GM needs and gets the bailout, and they end up producing the volt, given such a questionable financial future, is it a car you’d still want to buy.
For just a moment, think about a buying a 40K car with all the electronic wizardry of the volt and then having NO WARRANTY NO DEALER SUPPORT…If GM goes under, thats what you’d end up with…

Dec 1st, 2008 (7:10 am)A business associate of mine has a Prius. He gets 50 mpg in summer driving, but only about 42 mpg in winter driving (in Maine).
Cars in general get lower mileage in the winter for a number of reasons (warming the car, longer periods before engine warms up, colder tires, etc.), however, one difference is that cold air is more dense. Aerodynamic drag is proportional to air density. So colder days result in less mileage.
With an EV, if a heating system is used, it will consume energy. The Volt is designed to consume 200 watt-hours per mile. For 40 miles, this equates to the 8 kWh of usable capacity in the battey pack. If one uses resistance heating, and needs 3 kW of power, this will consume 2 kWh over the 40 minutes it took to go 40 miles at 60 mph. This equates to 25% of your usable energy! (so range would be less than 40 miles).
If a more efficient heat pump system is used that only requires 1 kW, and at 65 mph the Volt requires a little more than 200 Wh/mile, lets say 220 Wh/mile, then power consumption at speed is 220*65 + 1000 = 15,300 watts or 15.3 kW. Since Bob had only 4.8 kWh in his battery pack (8*0.6), this energy would only last 0.3137 hours at speed.
This equates to 65*0.3137 or 20.4 miles.
Seems like pretty good performance to me.

Dec 1st, 2008 (7:35 am)#12, #18 Duane Hamblin,
I don’t think pure EVs will take off anytime soon.
First, pure EVs need a whole new infrastructure to deal with longer trips. The infrastructure of liquid fuel filling stations took around 50 years to fully build out. A fast charge electric filling station infrastructure will take a long, long time (if ever) to become ubiquitous.
Second, Ethanol is the perfect solution for longer range trips. Obama will mandate that all new cars are flex fuel by 2012. Liquid fuels have much better energy density than any battery, including EEStor. Liquid fuel filling stations exist everywhere today. It’s trivial to convert a gas station gilling pump to ethanol. Cellulosic ethanol is real, and cheap. Check out http://www.coskata.com/ . GM is a major investor in this company.
So there’s no real need for pure EVs. The combination of EREVs and ethanol can completely replace gasoline, and without any major infrastructure changes.
The only real issue is what to do about all the other oil we consume. Only 45% of U.S. oil consumption is gasoline. Diesel, jet fuel, home heating oil, industrial fuel oil, plastics, petro-chemicals, etc. make up the other 55% of our oil consumption.

===========================================
What you have seems right to me, but Lyle has given us an extremely helpful item of information in the speed. It was high “65 mph or greater” according to Mr Lutz.
What you don’t include is use of the fact taht the aero drag goes as a power of the velocity. So, if all electric range (AER) is 33 miles at 65-70 then the AER will be maybe 50 miles at a steady 50 mph and maybe 60 moles at a steady 40 mph. These are the commuter speeds that really count, for many many drivers using the car to go to work and come home on a daily basis. As there is always stop and go in real driving, the AER will be somewhat less, but the result is going to be at the level people are expecting, or maybe even more.
I’m very glad to hear these numbers, as I was worried that they would say “yes 40 miles range at 10 mph” or some kind of extreme like that. Accepting Lutz’s numbers as a reference, the Volt will be well over 40 miles AER for many of us, most of the time.

Dec 1st, 2008 (7:46 am)Is it just me or has everyone forgot that the original estimate was 40+ miles on a full charge, and now GM is trying to sell a car that as barely getting 30 miiles on a full charge as a good news story. What I am hearing is continued excuses for missing the target on the vehicle: original price estimate adjusted from $24k to almost 40k, original design chages from awesome design to knock-off Prius, and finally, original full-charge mileage estimate adjusted from 40 miles to barely 30 miles. People, do the math. You are way better off buying a $19,000 hybrid that gets between 50 and 60 mpg, than 30 miles on a charge at $40,000. Maybe if the GM CEO were’nt flying everywhere on their private jets and spending their multi-million dollar salaries, they could afford a little more reaserch and development and possible produce a vehicle that does what they originally sole to the public. As with Stuey’s comments, why is it “some guy” can build a 75mpg hybrid in 1979, yet GM can’t even meet build an efficient electric car. Tesla Motors did!

GM’s CEO has said the Volt will be “mid-to-high 30s”, and there is a $7500 tax credit, so the Volt will cost around $30K after tax credit.
As for the design, the aerodynamics of the concept car was terrible. They said it actually did better in the wind tunnel backwards. So there was no way that design would actually reach 40 miles electric range.

Dec 1st, 2008 (8:09 am)Dave,
You’re a dreamer…. right now the Volt hasn’t even got off the assembly line; so the current mileage it gets is zero. The Toyota gets a proven 50mpg. I need a car today and I currently drive 60-80 miles per day. I was first excited about the looks and initial tech. announced by GM, but judging by the changed styling (boring) and and current design difficulties, I’ve concluded this entire project is going nowhere fast.

Dec 1st, 2008 (8:10 am)Wow. There are a lot of posters here upset about not getting 40mi in the cold at highway speeds.
As I recall, the 40mi range was quoted for the EPA City Test. If you look this up you’ll find that there are frequent stops, hard accelerations, and some relatively high top speeds included — all of which are highly inefficient activities. I don’t believe there was ever any promise of 40mi of range on the EPA highway test.
With that in mind, RB (Post #43) is absolutely right on. Lower speeds with smoother driving habits will yield longer AER — in some cases substantially longer. EV drivers have known this for the last century battery powered vehicles have been around. The same will happen with a standard gasoline vehicle — avoid highly inefficient driving and you get substantially better fuel economy.
Before bashing the vehicle too much we should really wait until some unbiased testing can be done on the production model. I know it is hard to sit on our laurels that long, but how else are we going to get an accurate picture? An unofficial test by Lutz with some numbers (promising or not) isn’t really the same as the standardized testing done by the EPA, nor is it the same as reports from actual owner experience. I still have high hopes for this car and while the test wasn’t in super low temps (yes, I’m in MN as well), the results are still promising. Especially as I don’t drive anywhere near as aggressively or fast as Mr. Lutz.
As for heat from the engine… yes, you can get heat from the engine when running but that isn’t the primary heating component of the vehicle. It will use resistive elements in the seats to help with perceived temperature (much more efficient as it uses very little current). I do expect that the vehicle will pre-heat the batteries if plugged in. This means that the “engine runs to heat the batteries when really cold” statement would only apply when not plugged in. For most people that would only be on one end of a commute. For some, it would almost never occur because they have the ability to plug in on both ends of the commute.
The Prius might net you better mileage (and my Insight certainly will) if the Volt can’t be used in an environment that leverages the AER. That isn’t what it was intended to compete in… but if you can leverage it you can use very little fuel indeed.
I have to agree that the projected price is a real downer, but to echo others here… it hasn’t been officially declared yet.

1) the Volt will cost $30,000 after tax credits.
2) The Volt will not “sit at a stop light while the ICE run at 3500 RPM to recharge the batteries”. The Volt’s gas engine will switch to a lower RPM, or shut the engine off if the light is long enough. The Volt does not significantly charge the battery.
3) You say you drive a 100% electric car. What’s your other car?

Dec 1st, 2008 (8:20 am)ken @ 50,
The Volt’s suggested retail price is not $40,000. The price hasn’t been set yet. Even if it ends up being $40,000, there will be as much as $7,500 in tax rebates from the government, so it might end up costing you $32,500. We can be fairly sure that a Prius with a few options is going to cost around $25,000 in 2010–that’s what it costs now. The Volt is almost certainly going to cost you more out of the box, but probably no where near twice as much as a Prius. And the Volt should cost significantly less to operate (i.e., it will use much less gasoline than a Prius).

If you drive 60-80 miles per day and can’t plug in at work, you’ll be better off with a Prius. Note that daily milage that high puts you in a minority of drivers. 80% of us drive less than 40 miles per day.
As for styling, I think most cars are ugly. The only cars that look good to me are not affordable or practical, so I just buy cars that fit my needs the best.

Dec 1st, 2008 (8:31 am)I still do not see people plugging in their cars EVERY night, for the ride to/from work the next day. My gut feeling is that after the first electric bill, 75% are going to stop plugging in their cars, and simply going to run them on gas. In that world, the Volt is pretty good, but certainly NOT worth $40,000. While the Volt will look awesome on paper (still trying to trick the EPA MPG rating system), in the real world it will be way over-priced and mediocre. After a few years, the consumer will realize this and the Volt will tank, and GM will again be blaming everyone else but themselves.
(Quote)
Dec 1st, 2008 (8:32 am)It is common knowledge that resistive electric heat is not economical. I could see it being used to heat the seats but not for anything else beyond that. I think GM will probably sell the Volt with electrically heated seats with options available depending on the location where you live. Also, those options needs to be designed with the ability to add or change easily after the car has been sold. A kerosene or LP heater could be used for extreme weather and that’s assuming the Volt’s battery works well in that kind of weather.

Dec 1st, 2008 (8:39 am)Corn ethanol in this country takes more energy (all told) to produce than then the usable energy it delivers. (We use more oil today than we would with no ethanol.)
The only plausible excuse for it is having an emergency fuel supply in the event of a world war that cuts off imported oil.
It’s true that we need to use existing assets if we are to improve things in the foreseeable future.
Some have pointed out that as we move out of the oil era our massive century long investment in high speed roads will have become largely a poor and unneeded investment of prime real estate and capital. They also point out that our massive neglect of our only really efficient means of transportation (railroads) has destroyed our best alternative.
If all this is true, maybe we should look at transportation differently. If we will someday have a glut of super-highways or highway right-of-ways, and if short-range electric cars are feasible as we have shown, then why not use them in combination?
Railroad systems were standardized in the 1800’s. Track width (rail spacing became a world-wide standard). For compatibility reasons these standards are with us today. As a result trains are very long and very “skinny” (much too skinny for best hauling efficiency and for some very important uses we may soon need.)
A proposal:
Suppose we make trains 30 feet wide. Suppose we convert some of our major thruways to rail systems. Suppose you can easily drive your electric car onto a train crossways (think of stations that look like a massive toll gate with dozens of parallel entrances). Suppose you can also easily drive your electric car off the train without turning it around? Suppose you can charge your electric car if needed while on the train. Suppose these trains can move far more cars faster per linear mile real estate than conventional thruways as we use them today? Suppose you can use them, get to an urban area 50 or 100 or 500 miles away, and return having typically driven only 20 miles. Suppose energy efficiency due to this approach is typical for trains per hauled ton – an order of magnitude better than the millions of vehicles acting alone? (check today’s RR efficiency per hauled ton-mile).
Suppose we open ourselves up to real change.

Dec 1st, 2008 (8:47 am)I’ll keep it short:
If GM markets it as a 40 mile range, it should get 40 miles WORST CASE…at least at first. People are NOT going to understand why they only get 30 miles if the weather is cold and they are not on a city road.
I’m not saying this ‘current result’ is going to be the case for the production Volt, but 31 miles driving with the heater on at start of life is unacceptable, highway or not. Hopefully, on implimentation to its actual platfrom, the Volt can do 40 miles reliably in almost any situation.
I don’t want to only get 40 miles on a 67 degree day, with no a/c or heat and cruising around on a flat piece of landscape at 32 mph during the first year of the car’s life.
I don’t know what the expected variance between the Cruze mule and the Volt will be so I won’t draw any conclusions…yet.

Dec 1st, 2008 (8:54 am)The volt is neat, but will not change anything. Cost if a dealer even gets a Volt they will dealer mark up the thing so the car will cost way more than the sticker. The cost today is reported to be 40 to 45 grand. The cost in a few years and with the mark up..50++ maybe?? I dont see too many poeple spending 40, 45, 50, 50 + on a 4 door small car. There will be some, but these cars will be just like some other limited production cars, cool but you may only only see one here and there. This will not help GM. They have been messing with the Volt and the new Camaro for years. Why is that Chrysler can bring a car from the car shows to the show room in 2 to 3 years????The PT and the Callangher?? GM is so slow at moving the volt will be out , At a real price point, when the all others moved on to the next great tech.
As for the taxes, I may be off here but if the Goverment will let you write off another 7 grand on you taxes to offset the cost. You will not see a dollar for dollar return. Less tax yes, but 7 grand cash back ..NO. Maybe the fed will just give you the 7 grand back..LOL

Dec 1st, 2008 (9:04 am)So the Volt has “up to a 40 AER” but we should expect to get around 32 miles per charge. That sounds great to me. If we assume the heater was running, and I doubt it, and we assume the energy draw was similar to the S-10 EV heat pump, i.e. 1.5 KW, then about .4 KWh of energy would have been used, leaving 4.4 KWh to drive the wheels.
That would work out to about 35 miles of AER with the imaginary heat pump off.
Bottom line, rather than use 8 of the 16 KWh, the SOC operating band should be expanded to 10 KWH, so more of us could expect “up to 40 miles AER.”

How do you figure that? Both the Prius and the Volt are supposed to get around 45-50 MPG, but the Volt will go the 1st 40 miles on electricity. Wouldn’t the Prius have to get in the 80 MPG range before it beats the Volt in the scenario you’ve layed out?

Dec 1st, 2008 (9:14 am)Question from a non-engineer: Why does the ICE have to be 1.4L if its purpose is just to run the generator that charges the batteries? I have a 5KW generator in my tool shed that uses a 1-cylinder, 10 HP ICE. And I have a Prius with a 1.4L ICE, but that’s part of the drive train, not just there to charge the batteries. Like I say, I’m not an engineer, so there’s probably a simple answer.
(Quote)
Dec 1st, 2008 (9:17 am)Lutz didn’t say anything about using the heater, and if I was doing the driving, I sure wouldn’t be burning up my range by turning on the heat at 30 degrees, it just isn’t that cold. Maybe I would have hit the seat heater but not the heat pump. And having Lutz mis-speak, ‘19 miles all electric, no, it was more than 20! Thats the ticket,’ doesn’t engender a great deal of confidence in GM’s prowess or prospects.
That having been said, if the test was done at 70 mph, and if they really did use the heatpump and seat heaters, the range is pretty good. Over the past 6 months it seems like the people that crunched the numbers here were getting well thought out estimates of 40 miles on the city cycle and 32-35 on the highway cycle, with the heater taking off 6-10 miles off those numbers, (with more heater induced range loss on the city cycle). GM should have stated that the 40 mile aer was city cycle from the start so people wouldn’t be complaining about it now, but that would imply that they have a lick of common sense among them. I will leave that ambiguity intentionally.
Finally, to compare the Volt to the Prius or to the Insight is like comparing apples to oranges to grapefruit. They are all fruit but the latter two are much more closely related than the former. If you drive more than 40 miles a day, you aren’t an average driver and the Volt won’t fit your driving style as well as a Prius or an Insight. But if you are not in the top quintile of driving distance, it just may allow you to use less than a gallon a week. After the tax credit, a Volt will cost about $30,000-$32,500, which is about $5-7k more than a Prius. And you will be able to stop buying foreign oil almost entirely. With a little determination, and a nearby E85 gas pump, Chavez, King Abdullah and Putin will be looking elsewhere for their money. (Not to mention how much it will motivate a lot of us to put either photovoltaic cells or a wind generator on the roof of our home.)
EV’s and Hydrogen Fool Cells may be the bomb someday, maybe, but for the next 10-12 years, it will be EREV’s that mitigate our disastrous reliance on foreign oil.

The Volt generator will run at about 2200 rpm on the 1.4 L recharge engine. You can just drive normally and get both good power and very good mpg. This is worth alittle more $ to most people. I will not buy a car with less than 130HP. My current truck is 4 cylinder 160 HP (24 mpg).

(Quote)
Dec 1st, 2008 (9:33 am)That’s one big difference between the Volt and the Prius or Insight. The Volt will accelerate like a real car; it won’t dog along like my old 81 Plymouth Horizon. That’s a selling point that has hardly been touched on. People will be really impressed on the test drives.
BTW, those talking about running the electric powertrain on a tiny engine… sorry but it just doesn’t work that way. Used as a range extender, the ICE needs to be large enough to power the car entirely on its own plus absorb the efficiency loss of the generator.
A 10 hp Briggs simply will not push a 3000 lb car down the road at 75mph. So in that scenario, after the batteries ran low the car would have to stop and run the (5kw? ) gen for a couple more hours before continuing down the road.

The reasonthey are using the 1.4 l has been covered here a while back.
THere are a couple reasons, noise, vibration and power.
Your garage generator runs high RPM noisy and shakes, but who cares..put that into a car that can cost 30-40k,and would you be happy?
Didn’t think so. at that price that baby had better not be noticed
Also scales of economy come into play..the 1.4 is a production engine, and fits the flexibility part of the platform.
Best ICE efficiency can also be selected depending on the conditions.
Search some of theolder threads, there is one on the 1.4l ICE that got flogged about 3-4 months ago if I remember..

I imagine for those of us that live in San Diego like climates, the range would be 40 miles. If you consider how much Americans drive and where they live, I bet the number is not far off.
Worst case scenario numbers don’t sell cars for Toyota, Honda, or anyone else for that matter. Why should GM use a different yard-stick than everyone else?
(Quote)
Dec 1st, 2008 (9:49 am)#91 Ken,
The 1.4L engine was chosen because it is a production engine, and it has good efficiency. Since it drives a generator, it will operate at the speed necessary to maintain the battery pack at its low (30%) SOC.
At lower speeds, the engine is most efficient, so a bigger engine at 1800 rpm is more efficient than a smaller engine at 3600 rpm. Go check out large engine generator sets from Waukesha, Fairbanks Morse, and others. They typically operate at 1800 or 900 rpm. Some low speed diesels operate at 450 rpm (60 Hz applications).
GM is just applying best practice in engine generators, yet still providing the 50+ kW this car will need to climb a 7% grade at 60 mph (let’s see the home built jobs mentioned earlier to that!).

Doug, the Prius doesn’t get 32 MPG, it gets EXACTLY the real world number it has listed. The EPA/GOV issued mileage estimate 48/45, blended 46MPG.
2008 real world returns, based on well over 100 vehicles reporting –>46.5MPG. It actually does a little better.

As I said before, I’m not going to draw out a conculsion on what the Volt will actually do. Once we are get numbers from a ‘production-alike’ Volt, then we will be able to extrapolate all the ‘fancy math’
But I will say again the 40 mile AER is supposed to be END OF LIFE…I don’t see anyway to paint this 31 mile range, on a fresh out of the box mule, on the highway with the heat on as a good sign.
If we take it farther, and start to estimate how much battery degradation will take place over the expected life of the vehicle…what does that do to forward looking range expectations if thus is the jump off point?
/again, still to early to condemn the project by any stretch, but we have this information, so we have to look at it as objectively as possible

Dec 1st, 2008 (10:01 am)I agree with #92 ziv, it isn’t a fact that the heater was on. It was Lyle’s presumption, “…presumably heating the passenger cabin on a sub-freezing day” If you go back and look at the photo acompanying the 60%/19-mile article, only one person is wearing a winter coat. The rest are in sport coats. If I were to guess, I’d say Lutz’s hot air heated the cabin.
I hopefully await real numbers.

As for Statik comments about getting 40 miles in the worse case condition… I understand your point about Joe the plumber won’t understand why he only gets 40 miles in city driving… City driving is a known preset condition as your worst case scenario is what? 40 miles in mountains with 2 feets of snow… You are asking something that even ICE car don’t have to tell you as the mpg are in optimal condition that most of us have a hard to reproduce in normal driving condition.
It doesn’t make sense and you know it.
What I would say is, if it was in fact 20 miles @ 65mph @ 60%, 100% of the 20 miles, then this is more then encouraging

Were you going uphill? Were you using the heater? What was the outdoor temperature? How fast was your average speed? How far did you drive?
It does not get EXACTLY the real world number. That is impossible. People in this post can’t even agree about factors that can lower and/or increase fuel economy. Can you imagine what happens when a bunch of lawyers get involved?
Is the Prius a remarkable feat of practical engineering? Of course it is. Does it get good fuel economy? Of course it does. Does it get EXACTLY 46 MPG? I don’t know. Fuel economy numbers have always been and will always be very easy to debate. They should be used as a guide. Add to this the fact that this is not even a proeuction car. Getting up in arms about whether or not they are being deceptive is premature at best.
The guy said he got 20 miles from a battery that was 60 percent charged. I know that the gas motor kicks in when the battery hits a certain level like 30 percent or so. Meaning they don’t let the battery totally discharge. I also know it was cold out. I don’t know if he was using the heater. I don’t know if the batteries discharge their energy in linear way. I don’t know any of this. Nor does anyone else for that matter.

Dec 1st, 2008 (10:13 am)Kudos to Mother Earth News for reporting a 75 mpg, serial hybrid home-built with surplus AF parts and “lawnmower” engine generator. Beware of the opponents of genuinely effective plug in hybrid electric vehicles “killing” the technology again by price gouging, diversion of funds to other venues including their stupidly incurred debt and lies about batteries. Meanwhile, here is a hard fact: if Bob Lutz is telling the truth that the Volt went 20 miles on 4.8kWH then in the entire USA in the summer, a $5000, solar electric system can replace the 4.8kWH for at least the 25 year warranty of the solar modules. In other words, 20miles/day driving for $2.23/day on sunshine, worst case and I am including Alaska.
For Southern California, the number would be $0.50/20 miles.

Dec 1st, 2008 (10:21 am)#91 Ken Says: “Question from a non-engineer: Why does the ICE have to be 1.4L if its purpose is just to run the generator that charges the batteries? ”
————————————————————————————–
The Volt’s gas engine (ICE) mostly provides power directly to the electric motor. The ICE rarely charges the batteries, and never much above 30% charge.
When the Volt’s battery gets down to around 30% charge, the gas engine comes on just enough to maintain that 30% charge on the battery. This 30% charge level is called the customer depletion point (CDP).
I’ve drawn some pictures that hopefully explain this better:
http://mysite.verizon.net/vzenu6hr/ebay_pictures/Volt_Electrical_Block_Diagram.jpg
Having the gas engine charge the battery significantly would be bad for 2 reasons:
1) It would wear out the battery sooner;
2) It would be less efficient, since electrical->chemical->electrical conversions have efficiency losses.
I believe the current Prius has a 1.5L engine. The next gen Prius will have a 1.8L engine. It’s not so much the side of the engine but the engine tuning that makes it efficient. Normal gas engines use an Otto cycle cam tuning that scarifies efficiency for more peak power. Atkinson cycle engines sacrifice peak power for more efficiency. Since the Prius has a battery and electric motor for peak power to help the gas engine with peak power, the Prius can use Atkinson cycle.
Similarly the Volt’s gas engine generator electrical output is augmented by a large battery pack, so the Volt also uses Atkinson cycle. In other words, the Volt’s gas engine only provides average horsepower. Peak horsepower is provided by the electric motor, even after the gas engine turns on. That’s how you get 150 peak hp from a 75 hp gas engine.

The numbers reported by Lutz in his highway test imply to me that 40 miles on a charge is possible and maybe even plausible. That doesn’t mean that I should expect to get it under all conditions.

Ok, same dislaimer goes for you as I gave franky in #109. Obviously not every driver is going to get 46 mpg. But the average driver, who drives like a average person is going to get pretty close to that number.
————–
I don’t really want to split hairs all day long. My basic premise is that if GM markets it as 40 mile range, then the average consumer/driver, should get that 40 mile range 90% of the time. (Discounting snowstorms, mountain trips, etc.).
Nutshell:
If the Volt only can achieve a 40 mile range going 40MPH or less, that means it will very rarely ever achieve its stated range.
All I am looking for is a assurance that if I buy a car that is advertised as going ‘40 miles electric’ (and I drive like a normal human being) that I can expect to achieve that number in the real world. If it can only average of 30 or 35 miles over its lifespan…advertise it as such. This is cutting edge stuff here and highly visable, it is better to overdeliver than to overpromise.

———————–
A good question. Here is my opinion. GM has shot themselves in the foot with past transgressions. Approximately 60% of new car buyers in America will not purchase an American made car. That is a huge number. Now imagine if GM brags about the EV range at BEST CASE scenario, and hardly anyone gets that. Now imagine that there are reporters with axes to grind against GM. The Volt will get slammed in the press in a big way.
GM has made complete junk (fact or perception. Either is bad) in the 1980s and 1990s.
The Volt has a chance (if GM gives it the chance) to turn things around by being honest about the car, and making the Volt a very reliable product.
If they try to pull the wool over peoples eyes, it won’t take customers long to search elsewhere for a car.

Dec 1st, 2008 (10:40 am)Mitch, You obviously don’t have a clue. I have been on this board from the beginning and the information I cite is fact.
-They did change the price, the design, and the mileage estimate (All Significantly).
-Tesla does make a superior electric vehicle that crushes the 60% /20 mile performance.
-And the diffence in price and eprformance does not out-weigh the value of the Honda or Prius. The $7500 tax credit is a one-time good deal that simply displaces GM’s debt on the shouldders of Uncle Sam. Moreover, all of you lemmings seem to forget that you will not only have to pay for gas, but will also have to pay for the electricity to charge your batteries. With the true expenses (Price, gas, electricity) lower price of the Prius (with a 45-50 mpg offset for fuel savings) the Volt driver will have to drive his car for upward of seven years to simply make-up the $15,000+ price differential.
Although the Volt started out as a great idea (as do many of GM’s ideas), It has also fallen victim (as with many other GM products) to the typical overpriced-cheaply manufactured mentality that has lined the pockets of the CEO’s and driven this iconic corporation into the ground. For evidence of this history, simply compare the dowward trend of the company value (beginning circa early 70’s) to the changes in the vehicles they produced. The quality/design down-turn is painfully obvious.
You can be a lemming or (GM Cheerleader) if you like, but I prefer to evaluate the facts and make educated decisions.
CORPORATE SPIN IS NO DIFFERENT THAN POLITICAL SPIN. ITS ALL LIES AND HALF TRUTHS.

The outside temperature is not relevant here (except that it increases drag.) The battery temperature is what’s important. And if the battery was in warm garage before hand, then it wouldn’t have suffered from the lower outside temperatures.
We do not know if the cabin was being heated during the drive. If you’re trying to post good number for the press, you’d bundle up and turn off the electric heat.

IIRC, GM said they are targeting a little more than 40 miles of range to be sure that it gets at least 40 miles under most normal conditions, but they’ve also said heating and air conditioning will have an impact.
We’ll just have to see. I wouldn’t read too much into mule tests. Firmware will be tuned much better when the real Volts come along. I’ve heard the induction motor controller (a.k.a. inverter) firmware is really complex, so I’ll bet they’re still tuning it…

Yeah, I was pretty much the same way on the current gen. The Prius seemed to run functionally well, (as well as I was expecting), but the car itself had too much ‘nerd’s shoe’ for me. Too pedestrian maybe? I don’t know.
The next gen seems to have improved the interior, but I’m still not digging the exterior look…I’ll make the final call at the Detroit auto show when I can see it in person (if all the auto manufacturers don’t back out by then, lol). I know I won’t be buying it for sure (as I have already booked a Insight).
However, my intense desire for a electric vehicle supercedes almost all other desires in a car. (other than 4 seats and being able to service it locally) So if Toyota says I can put my money down on a Prius with the ‘Plug-In’ option…I am totally there, without hesitation.
PS) I agree with your wife, I hate the digital display. I don’t mind all the fancy stuff, I actually like it…but let me keep the analog speedometer, the car guy in me hates digital

There was an article about this here on gm-volt.com a couple of months ago. GM said that the Volt’s ICE will run at a few different constant RPMs. It’s not continuously variable. It’s more like small, medium, and large.
Within each constant RPM, the amount of fuel consumed varies dramatically depending on the load.

That tells me that I am not the only one waiting for an electric car, So come on VOLT. But GM is never going to get there if they charge 40K, tax credit or not. They seem to be counting on the feds to help them sell the car. I would like to ask Lutz, Wagner and the rest…do you want success with the Volt or do you just want to stay wealthy?

=========================================
That statement seems reasonable at first blush but it is just not sensible. AER is going to depend strongly on speed. There is no way around it.
So to say the rating should be for the worse case is to say the rating should be for 100 mph, or whatever maximum speed the car can sustain. That speed is far higher than most people will go most of the time, so the rating will be misleading because it will be far too pessimistic.
Instead of worse case, the rating needs to be for stated conditions. Most likely those will be the EPA City Cyle. If GM wants to go beyond that, the number should be for conditions that GM can describe in a sentence or two. Then we get numbers that are worth understanding.

Dec 1st, 2008 (11:24 am)After all this time and all the effort Lyle has put into this site there are STILL people blogging how the ICE motor will “recharge” the Volt battery. The ICE motor will NOT recharge the battery. It will turn a generator that will supply electricity DIRECTLY to the electric motor. The remaining charge in the battery will augment the ICE engine. Just the opposite of today’s Prius and Civic Hybrid’s if you think about it.
Someone blogged about a 5hp lawnmower engine turning a generator for someone’s homemade Volt. Sorry, the math doesn’t work. 5hp is not enough power to turn a big enough generator for a practical car. 5hp is not enough to either power a car at practical speeds and range nor is it enough to recharge the batteries WHILE DRIVING. It CAN be used to recharge the batteries while the car is stationary but at 5hp you’re going to have a long and polluting charge cycle. Don’t believe these homebrew claims. If the claims were true Toyota would have done their Prius with a 5hp engine! Think about it.

You’re actually making this more difficult than it needs to be. Of course the Volt will have a 40 mile range. The only question is: What is the driving style used?
Driving styles make all the difference in how much energy you use. For example, if you look at the Urban, Highway, or US 06 driving standards you find, when compared to data from actual US drivers, that very few drivers have the light foot required by Urban or Highway but that most drive less aggressively than US 06. This is the reason why EPA mileage estimates before the 2008 model year always overestimated the mileage — they used Urban and Highway and then adjusted. However, for the model year 2008 the tests changed, and current testing is much more accurate, as most drivers will attest. If you’re a 19 year old with a lot of testosterone in your system you can get less but most drivers will find it accurately reflects, or exceeds, their driving style.
The short answer to the question of what driving cycle is therefore straightforward: The Volt SHOULD have a 40 mile range using the driving styles for the standard EPA test cycles. Whether it does or not is the open question. We’ll have to wait and see. Since GM hasn’t defined what style it’s using when talking about a 40 mile range, we don’t know.
But we do have a very good hint. GM’s published work uses the style defined by the California Association of Governments study — which actually measured the driving style of real drivers. It defines a style for the median driver which is somewhere between Highway and US 06. This style is, I believe, slightly more aggressive than the style used in the current EPA tests. Since all of GM’s research for its hybrids has been built around this style, I’d expect the Volt to have a 40 mile range using it. And that should meet or exceed the current EPA standards. (And a longer range at beginning of life).

Yeah, I’m holding my breath to see the “plan”.

Fun? Interesting, maybe. Heartbreaking, probably. Fun? Alas, I can’t see it that way. Unfortunately, I have largely come around to your way of thinking. Back in a few months for another bite. The death of a thousand cuts.

Sounds like you had a excellent day…glad to hear that. Nothing better than having the family around, and having them all happy to be there.
For me American thanksgiving is like a imposed 24 hour coma. There is nothing good on TV, it is not the weekend so all my friends/family are working…but yet there is also no market action/CNBC to watch during the day.
/Ok, I watched football with some ‘power napping’ on the slide…so I guess it wasn’t all bad

“However, my intense desire for a electric vehicle supercedes almost all other desires in a car. (other than 4 seats and being able to service it locally) So if Toyota says I can put my money down on a Prius with the ‘Plug-In’ option…I am totally there, without hesitation.”
A few things to keep in mind:
– I have and intense desire for an electric vehicle also.
– The Prius is not an “electric vehicle”. Even the PHEV version still runs with the gas engine coming on occasionally to keep the catalytic converter up to operating temp.
– Further, the heater (I’m assume you use it more than I, in Chicago) is designed like most cars, and gets its heat from waste energy running the engine. So the engine will cycle on and off to heat the cabin. Unfortunately for the heater, it is a very efficient engine, though slightly larger than today’s version.
– I believe Volts will appear in showrooms before PHEV Prii, but that’s just my opinion. Toyota is very cautious about putting out new technology.
– If it weren’t for the Volt, I would be ahead of you in line for a PHEV Prius.

Dec 1st, 2008 (12:25 pm)This all kind of gets back to what is the MPG/MPC of the Volt. If they run the standard test for highway and city MPG on the volt as a loop after a full charge untill the engine kicks in, they can give us a value on Miles per charge. That way we should be able to say ok if I drive my prius like they do in the highway test I’ll get 48mpg or in the Volt I’ll get 36 miles on a charge. Seems like the way to go to me
(Quote)
Dec 1st, 2008 (12:35 pm)I agree. I’d like to see MPC rated per the MPG testing; then MPG rated separately starting at the point where the ICE kicks in for power.
Like 42 MPC, 48 MPG city / 37MPC, 43MPG highway… or whatever it actually comes out to.

I guess all these exclusive interviews with Bob Lutz and other GM executives are useless, as we now have some intellectual authority visiting this site.”
LOL, Amen! I think that Lyle should immediately convene VoltNation 2. He can skip the GM people and just have keynote speakers from this list. It seems that many are absolute cesspools of information that have heretofore gone unnoticed.

(Quote)
Dec 1st, 2008 (12:55 pm)What i meant to ask – How does the electrical system manage peripheral electric devices and what is the effect on the 30 mile range? LIGHTS AND AIRCONDITIONER should draw significant amperage away from the battery. The result would be a reduction in range when operating in the “battery only” mode and, potentially, a significant decrease in overall mpg. Is Chevy ready to share details with us?

=====================================
Ya, I know it isn’t a flawless EV by any stretch. It will kick on under hard acceleration or speeds over 62 (not 65, hehe), and their is some subsystems that will also need to be ICE powered when activated.
Right now though, I have little to no standards. Even when it comes to range, at best 11 miles in the Plug-In Prius. I will buy anything that comes out to fit my ‘4 seat, serviced locally’ mantra.
/personally, if I had the choice today of anything promised to the market by 2010, I would take the i-Miev in a heartbeat over anything…strictly because it is a pure play. The Volt and the plug-in Chrysler van (because of its obviously functionality) would come in a dead heat for second.

“They did change the price the design, and the mileage estimate (All Significantly)”
in order 1- Please provide link to VOLT price, I have seen estimates, guesstimates, and fabrications, quotes of maybe and possiblies, but NEVER a PRICE.
2- we knew the design was going to change…they said so at teh press release to build it.
3- the 40 mile estimate has always been the goal..from what and when was it it changed..I was at the auto show and they have always stated a 40 mile range.
“Tesla does make a superior electric vehicle that crushes the 60% /20 mile performance”
Pay $120,000 for a 2 seat, sports car, niche vehicle? and you are comparing it to a Chevy? you are comparing apples and hand grenades..like saying I wont buy a Z6 ‘vette at 80,000 because it no 250,000 lamborghini…
Lets face it..GM can (and did) build a long range, 2 seater super aerodynamic all electric 200 mile range car in the 1990’s…
“And the diffence in price and eprformance does not out-weigh the value of the Honda or Prius”
By your aurgument inthe previous quote..you should still be buying the Tesla because as you say the “Tesla does make a superior electric vehicle that crushes …” and the words Honda / Toyota can be inserted here.
Fluff and stuff…If you have been here so long, then you need to read the posts closer…
I never mind factual aurguments, links to proof (Like statik and I disagree with him often as well), but aurguments based on fluff, personal opinion (even based on personla facts of which I am guilty of as I own 3 GM products that have litterlay original EVERYTHING over 200,000 miles so I think since hte mid 1990, they majke excellent products..a personal “fact” if you will that I can back up) and then contradicting yourself is not a winning thing.
Do get po’d..I am not looking to make enemies, but I call em as I see em..if you have been here so long, it certainly did not sound like it..

Dec 1st, 2008 (1:14 pm)Six of one or half a dozen of the other?
So the SoC is restricted between a 30% – 80% range, using half the available capacity to avoid battering the batteries and he reports that he started at 60% and you want clarification as to whether he was at 60% of the battery’s capable capacity, where 80% means it is fully charged or whether he meant that it was 60% charged from 30% capacity where 100% means it is fully charged at 80% capacity?
Well I have news for you, either way he was at 60% because at that point both measures mean the same because…
30% + 60% * (80% – 30%) = 60%
So you might as well not have asked the question at all…
Now if he had said 75%…
30% + 75% * (80% – 30%) = 67.5% != 75%
and the question would be meaningful.
Its like he said it was -40 degrees outside and you ask to clarify whether he means Fahrenheit or Celsius…

Dec 1st, 2008 (1:23 pm)A lot of folks here looking for “Real World” metrics on mpg.
Just get a 40 yr old exsmoker female on men-on-pause to drive it to work that’s about 15miles away. That’s a real world scenario.
My wife is available for rent to drive your car to test. If you can put up with her she’s $1000 both ways.
Now back to the Volt. Does anybody know what type of generator is used? I know you have all specified it’s 53Kw/h but who makes it and what are the specs? Is the running RPM speed of the ICE connected directly to the generator? Or does it go through some gear ratio/transmission to reduce rpm but increase torque?
Also, does anyone know how much energy is recaptured from the regenerative braking?
Just curious.

Which is 48.1 mpg using gas. No significant difference as there would be with E85, which would equate to a most impressive gas mileage of 63.9 mpg.
BillR #100 – Engine
You are of course absolutely right that we can rest assured that GM engineers can pick the right engine for the job. Some other factors: added vibrations from three stroke engines, more emissions from a larger engine (due to cycling on and off), and cost and weight. It’s a tricky question with many trade-offs.
Fiskar is buying GM engines, and one reason may be some free technical advice along the way.

Dec 1st, 2008 (1:26 pm)As to comment 152,
Even the CEO of GM came out a couple of months ago (after Chevy smacked everyone across the face with the pathetic Pre-Release photos of the Volt) and ADMITTED that they sold the price short when they claimed that it would be approximately $24,000. Moreover, he STATED that due to pursuit of the 40 mile performance goal, the vehicle was slated for pricing between $35,000 and $40,000, or approximately $37,500. So, you can continue to be GM”s lemming and suck-down the Kool Aid, but I’m not buying it. The fact is, ever since they release the photos a huge number of “previously interested” customers went on a rant over the disappointing style changes, the exaggerated performance hype, and the ever-increasing price. This morning’s statement regarding Lutz’s excitement after driving the Volt was nothing more than a well written PR ploy to soft-soap the fact that the Volt is continuing to fail the exaggerated mileage estimates. I’ll bet the picture was even taken at a county club luncheon or some BS PR event, and the vehicle he is in is a rental that he drove from the hanger where his private jet is parked.
Wake-up and drink the coffee…not the kool aid.

I’m a “Joe the plumber butt” and can’t afford a Tesla. I want a Volt.

It’s obviously too dark in Canada these days! Nah, you don’t really want an EV. I may end up with one, but their upsides are minimal and the downside obvious. Why makes you think EVs are better than E-REVs?

Certainly no one will force you to buy a Volt. As for the price, it’s not exactly unusual to have the price rise on an unproven technology like this. AFAIK it’s happened with every EV so far, including those in development. What’s very impressive is that so far the launch date for the Volt has not slipped. That is a minor miracle.
I think you are right about the price being in the mid-30s. Everyone keeps saying 30K – 40K, most recently the “Volt girl ” at the LA Auto Show. With the incentive that’s $28K – $30K. Assuming this is correct, seems like a steal.

Dec 1st, 2008 (1:40 pm)When looking at Tesla Motors the important consideration is the technology. They have already come online that the will release a luxury coup in the 50k range and a Joe The Plumber version in the 30k. At 244 miles “per charge,” not 31 or 21, or whatever the Volt is now, I will wait for Tesla’s “Joe The Plumber” version instead of GM’s Joe-The SAP version.

Dec 1st, 2008 (1:43 pm)The 40 miles was always a best-case scenario. Hasn’t anyone else noticed that virtually every number GM gives is this way?
Price, engine size, tank size, equivalent household electricity use, production volume, looks, etc. Soon we will add in gas MPG and release date.
Anyone who is shocked when those numbers come in low hasn’t been paying any attention.
