Chevy Volt Will be Able to Hit 104 MPH

November 19th, 2009 | Posted in: Performance

voltteam

The Chevy Volt is no slouch.

A Volt ride and handling engineer named Mark Popilek said “I got it up to 107 on the test track, but we’re planning on limiting the speed around 104.”

At this point in development the integration vehicles have become highly refined.  In fact, GM has just started to allow journalists test drives in charge sustaining mode.

According to powertrain engineer Alex Cattelan, “we’ve been through three levels of hardware in two years.”

She also notes “the groups working on the second generation and third generation versions are still providing more information to us.”  Cattelan is confident GM will meet the November 2010 deadline.

GM vice chairman Bob Lutz spearheaded and conceived the Volt project back in 2006.  He admits though he displayed a lot of early bravado it was a bit of a long-shot, and that people even within GM were skeptical.

“I did place a lot of faith in the battery companies, who said they could have them ready,” said Lutz.

Lutz wanted the Volt to leapfrog the successful Toyota Prius.

“Three years ago, it was Toyota this and Toyota that, everyone thought only good things about them, and it was because of the Prius,” Lutz told reporters. “I wanted to overcome the incredible reputation Toyota had with the Prius, and we knew we couldn’t do it with just another hybrid.”

“The bar was certainly set high,” admitted Cattelan. “But there’s no way you can reach that goal if you don’t have it.”

    Hmm, interesting about the speed. he says “planning on limiting the speed around 104″, so it’s not got a limiter on it yet? if he was in CS mode then no biggie, as only 53kw is avaialble. but if in CD mode he should be able to go faster (112kw motor would top out at 145mph), unless there is some limit on power use (thinking that although rated at 112kw GM cap power going to the motor at some lower level – my calculations say 107mph requires 60kw). so if the power to the motor is capped, the converj upgrade is pretty straightforward, uncap the motor. you’d get a slightly higher (and unsustainable) top speed of 145, and better acceleration. you could balance the top speed, call it 115 and you could run (while depleting a full battery) for 30 minutes.

    Has anyone posted a CS review yet?

    It was said that about 80% of Americans drive 40 miles or less each day and that’s why VOLT batteries are designed to provide 40 miles of range.

    I wonder what percent of Americans have EVER driven over 100 miles per hour.

    I guess it will be good to know you can do that in a Volt if you ever want or need to.

    Get enough cars out so the Volt doesn’t just look like a PR thing. I know it’s real, I trust it will do what it should, now I just want to give GM my money so I can stop burning oil and start driving by hydro :)

    I would expect a high % have done it at least once. only a small amount would go that fast regularly though. I have to say i’d like a slightly higher top speed, but the use of anything above ~120mph is pretty limited, except on the track – which the Volt isn’t really suited for.

    104 MPH isn’t a practical feature, but it does reinforce the idea that electric cars don’t have to be golf carts. They can be Tesla-like. Also, it provides a connection to the American heritage of muscle cars. Being able to go 100+ will get people into the show rooms who otherwise would have never considered an electric car. Anybody know the top speed of a Prius?

    Acceleration and handling will be more relevant points of judgment than top speed ever will. For the plain vanilla model, 0-60mph in around seven seconds would be real attractive; rapid 30-50mph and 50-70mph acceleration stages will really top things off; light, nimble, and responsive handling should absolutely seal the deal.

    Why 104 MPH? If I recall correctly, that was the exact speed for which a Prius driver got a speeding ticket. The ticket made front page news, was on drudge, etc etc because no one thought a Prius could go that fast.

    I have not found any CS evaluations yet either. Sounds like a claim that should have the name of the journalist or his publication mentioned.

    I believe the acceleration design goal was zero to 60 in less than 9 seconds – 1 second faster than the current Prius.

    In Texas there is a stretch of I-10 that is posted at 85 MPH. So a top speed near 90 would seem to be sufficient, and reduce the risk from folks who put their fun before the safety of others.

    Many cars have governed top speeds, the most likely reason the Volt is set to 104mph is that the lo-resistant tires are probably have a speed rating of R that allows up to 106mph

    N Riley: Such an odd number – 104.Why not 100 or 105?  

    An electric motor can generate three or four times its rated output for short periods, so realistically the top speed of the Volt will be limited by the controller rather than the motor.

    The top speed allowed by the controller, in turn, will probably be established by the rated top speed of the tires. If I remember correctly the top speed was originally said to be 88 mph or so. That may have been the guess as to the what the rated speed of the tires would be, and the new tires that Frank Weber is so high on may be higher than that. A “R” rated tire is good for 106 mph and GM may want to stay on the “safe” side of this number. (An “N” rated tire is rated for a top speed of 87 mph).

    My truck is limited to around 100. I have hit this several times. Feels like the brakes are engaged when that throttle backs down. I usually test the limits of any car I own.

    Top speed I have ever gone (on the ground) is red-line on a ‘70 ‘Vette. It’s around 140mph. At speeds near the speedo limit, mechanical speedometers are very inaccurate. It said 160, but, I know that’s not right.

    Gotta love states like Texas and Indiana with straight vanishing-point roads.

    Hollywood is filming a remake of the movie Red Dawn all over Michigan right now (even now as I type this they are just outside my office). The plot is basically the same, Russia/China invade a small town. There are plenty of Hummers in the shots (so far that i’ve seen). Hummer is now owned by a Chinese company (maybe it ties into the movie), so this is not such good publicity for GM. It seems like this would be a great opportunity to get the Volt into another movie. Especially when the movie release date is Nov 2010. People would watch the Chevy Volt in the movie theater, ask “what was that car?”, then go out & buy one.

    I think it was a matter of balancing performance and efficiency. 104 mph is plenty fast for the majority of Americans. Most people rarely if ever go over 90 mph. In fact, a lot of new pickups are governed to around 98 or 100 for top speed.

    I think the more important question is how fast it can accelerate up to its top speed. I would suspect with 273 lb./ft. at near zero RPM, pretty quickly. I’ve been faster than 104 on public roads. I got it out of my system.

    This is why the Volt has to be “spot-on” when it is released to the general public.  

    When the Prius was released to the public, I remember it being derided as “underpowered” and “not cost effective” back when gasoline was $1 or $1.50 per gallon. American auto journalists had a field day making fun of the car, and predicting that Americans would have no interest in this “weird little science project”.

    Ah, what a difference a decade makes.

    Similarly, it doesn’t matter if by chance and recession gasoline is $2.5/gallon in 2010, and auto journalists pan the Volt as “not cost effective” , “underpowered”, or a “weird little science project”. The Volt only needs to sell its projected 60,000/year the first few years to the visionary early adopters, until the 2nd generation Volt in 2015 or 2016 becomes a blockbuster success. It’s important to be ‘good enough’ until it is possible to be ‘fantastic’.

    A greater than 100 mph top speed is necessary for any highway going vehicle to be taken seriously. Being able to achieve 100, implies certain other performance attributes and also takes into account aerodynamic efficiency. i.e. if it can go 100 mph, then acceleration from 60-80 mph should be adequate.

    Many of us “car guys” and those who live out west see 100 mph fairly often. I’ve slowed down a bit, now that I’m in my 30’s, but still enjoy sustained driving at speeds over 80 mph on occasion. Just like those who have range anxiety…having an artificially low top speed gives some of us velocity anxiety. :)

    Then with a small headwind, it would dip into the battery.
    With a small tailwind, it could reach 108 mph without using battery power.

    Maybe it is related to the wear and heat on the traction motor ? It is connected directly to the wheels, so the faster the car, the faster the rotor is going… maybe the coolant system has some limit.

    I’ve got to say what’s finally happening is GM’s PR is alive. Exactly what’s needed. Real progress reports and policy resolutions. That GM decided on a 104 cap tells something about its tires. Of course hardware needs to be shaken down – but knowing that’s a 7/24 engineering team effort stands tall.

    My tops (in the stone age) was passing 120 on the speedometer in a Barracuda – nowhere near its top speed. Today’s supercharged Vette ZR1 with its 600+ hp ICE breaks 200. When it comes to racing speeds GM knows how.

    Good point.

    I read the Volt will be using Goodyear Assurance Fuel Max tires:

    That is a speed rating of 106 mph, although many family sedans have tires with speed ratings of S and T (112 and 118 mph).

    These fuel saving tires sound like a good match for the Volt.

    To leapfrog the Prius that gets 50+MPG at half the price with a car that gets less than 50mpg and over $40K is a pipe dream.
    What’s the big deal about going 104mph anyway? It makes everything less efficient therefore wastes energy. 65-85mph is the general speed, any faster is just a waste. Seems like a common theme here, to go in excess. That’s the problem with the US SUV market and why the US is so bound to the SUV.

    When the Prius was released to the public, I remember it being derided as “underpowered” and “not cost effective” back when gasoline was $1 or $1.50 per gallon.American auto journalists had a field day making fun of the car, and predicting that Americans would have no interest in this “weird little science project”.Ah, what a difference a decade makes.Similarly, it doesn’t matter if by chance and recession gasoline is $2.5/gallon in 2010, and auto journalists pan the Volt as “not cost effective” , “underpowered”, or a “weird little science project”.The Volt only needs to sell its projected 60,000/year the first few years to the visionary early adopters, until the 2nd generation Volt in 2015 or 2016 becomes a blockbuster success.It’s important to be ‘good enough’ until it is possible to be ‘fantastic’.  

    I respectfully disagree.
    Toyota was in a totally different class than GM when the Prius came out. Remember that today, most people think GM makes garbage. Whether this is true or not, is unimportant. The perception makes it true when it comes to sales. GM has put a lot into the Volt. Just making it good enough is not good enough. It has to be “spot-on” or the public prejudice against GM will remain. GM is a new company now. They had better start earning awesome reviews for the vehicles, or they are sunk. They must concentrate on making very good, very reliable, and honestly priced vehicles. The dealers need it, GM needs it, and our country needs it (in the form of jobs).

    Sorry, I hit the submit button by mistake, and I no longer seem able to edit.

    If the Volt can go 60 mph at 12 kW, it should go faster than 104 mph.

    Tire rolling resistance (RR) I believe is pretty linear with speed, but aero drag force (DF) is proportional to the speed squared. Power requirements are therefore, (RR+DF)*Speed. This is almost proportional to speed cubed. So max speed (Vm), with all 111 kW of the motor, is

    (Vm/60)^3 * 12 = 111
    Vm = 126 mph

    Note the top speed of the original concept was given as 120 mph.

    Using this same math, only with 104 mph as Vm, and calculating the power, it equates to 62.4 kW.

    Although this is more than 53 kW, the Volt may use less than 12 kW at 60 mph, or with the linear component for rolling resistance, the exponent may be less than 3. For instance, if the Volt used 11 kW at 60 mph, and the exponent was 2.75, this calculates to 50 kW at 104 mph.

    From Detroit News The daily test drives have led to changes in everything from how owners will recharge the Volt to an eleventh-hour redesign of the door for its charging port after it fell off in car washes.

    That door falling off in the car wash is just the kind of problem that has made gm cars infamous. It is wonderful that Volt is getting enough testing to get rid of such “little” defects. It really is essential.

    People didn’t really care about fuel efficiency back then. Gasoline was rediculously cheap for years. No one talked about peak oil or worried about the price of gasoline. This was pre-9/11, so no one worried about where oil money was going. The economy, in general, was much stronger fundamentally. We had an overall trade deficit, but it was managable. No one was worried about the value of the dollar going off a cliff. And the general attitude towards the environment was very different.

    The volt is a single gear ratio between the motor and wheels, right?

    I suspect the 104 MPH is where the motor limits out for maximum rotor RPM. The optimum ratio of gearing is the ratio that just barely gives the car the ability to slip the wheels on dry pavement. Any lower ratio (higher starting torque) is of no benefit and limits top speed. A higher ratio lowers the acceleration and gives a higher top speed. If the car already is capable of 104 MPH, that’s high enough so no need to up the ratio and limit acceleration

In the comparison, they boosted the EPA ratings of the RAV4 by 2 mpg over what Toyota has on their site for the same car today. I would think Toyota would have this right.

    So how would the experience be since the battery would, under the above scenario, be required to rely on the gasoline motor?

    I agree with the observation that most American drivers will not take seriously an electric car which has an internal speed limit under 100mph, however pointless this might be in normal driving.

    The performance of a conventional car at normal speeds can be related to it’s absolute top speed. For an electric, it’s pretty meaningless, IMHO. I think many people who buy the Volt with Prius expectations of performance will be astonished.

    That’s not to say that I wouldn’t appreciate 100+ mph in the unlikely event of having to escape from a tornado or pyroclastic flow (or hordes of the damned, Elvis in a UFO, etc), but the odds of these are not all that great ;-) .

    mikeinatl.: I guess it will be good to know you can do that in a Volt if you ever want or need to.

    To all those concerned about acceleration and maximum speed you are probably looking at the wrong car. It’s purpose isn’t to be a sports car. Its an electric vehicle with one soul purpose. Fuel efficiency. GM has an entire line up of cars and trucks with big engines which are specifically designed for those of you who are horsepower junkies. Infact its exactly why GM got into trouble in the first place. All they were interested in producing was high powered mammoth sized vehicles that went through gas faster than a binge drinker at a wedding reception. They continued doing so even when it was ridiculously clear that this wasn’t what the market wanted anymore as evident by the popularity and overwhelmingly high demand for the Prius and other high MPG vehicles. The Volt is a very welcomed departure from that philosophy.

    The irony is, the vast majority of people who buy high horsepower vehicles somehow wind up directly in front of me dragging their behinds down the freeway in the left lane holding everyone up. Never understood that. LOL. This car shouldn’t and doesn’t have to tout high max speeds and muscle to get everyone interested. The Prius didn’t and thats because the market it spoke to wasn’t interested in muscle. There is already a huge population of people out there who don’t care (like me) about it’s top speed so long as it can maintain a respectable freeway velocity while sticking a hot poker in the eye of OPEC. I’m completely aware that I’m not buying a Camero.
