Voltec-based Cadillac is now official

 

General Motors verified previous rumors on Wednesday that the 2009 Cadillac Converj concept will go into production as the Cadillac ELR.

As GM-Volt readers know, the luxury car based on a Voltec powertrain debuted at the 2009 Detroit Auto Show, and GM was noncommittal for quite some time as to whether it would build it, even though enthusiasts immediately praised the Converj concept.


2009 Cadillac Converj concept.

“The concept generated instant enthusiasm,” Vice President-Cadillac Marketing Don Butler said to CNN Money. “Like other milestone Cadillac models of the past, the ELR will offer something not otherwise present – the combination of electric propulsion with striking design and the fun of luxury coupe driving.”

The Volt is practically edging into Cadillac territory in some respects already, so this new vehicle is likely to be a very special car.

Cadillac said it chose to call the new vehicle the “ELR” to indicate the car’s electric propulsion technology and to stay consistent with the brand’s 3-letter international model naming convention.

Recent rumors have said the previously un-named development upon the Converj concept will use a Volt 1.5 generation powertrain sporting more gasoline and electric power, as well as all amenities one would expect from a premium car.

But General Motors has not announced its specifications, price, or when it will be built. The company said it will do so “later,” but otherwise is drumming up the enthusiasm for its pending encore to the Volt and Opel/Vauxhall Ampera.

“There’s no mistaking it for anything but a Cadillac. An aggressive, forward-leaning profile and proportion showcases a uniquely shaped, modern vision of a personal luxury 2+2,” GM (GM, Fortune 500) Vice President of Global Design Ed Welburn said.

As a “2+2,” the ELR will, like the Volt and Ampera, fit two people up front, and two in the rear seats. It will be about the same dimensions as a Volt/Ampera.

Although GM is not saying, Bloomberg added to the rumors by reporting “a person familiar with the plans” has said GM will price the ELR below the $57,400 Tesla Model S. Performance was estimated by this same reported insider as being at least as fast as the Volt, with more all-electric range.

Considering a fully spec’d 2012 Volt will cost north of $45,000, what will this mean if the estimated mid-50s price for the ELR is true? Would GM retroactively decrease the Volt’s price to keep the Cadillac from cannibalizing its sales? Or do you think a $10,000 or so spread between the Cadillac and Chevrolet will be enough?

And speaking of more luxurious, how closely spec’d do you think the production ELR will be to the beautifully appointed Converj which had wool-blend carpets, silk headliner, synthetic suede, genuine leather, wood and aluminum trim, highly sophisticated electronics, and more?

    The interior of the concept was very similar, at least in design language, to the current CTS lineup. Which, looks great and is very high end.

    I think a lot of things will change component wise, but for the most part have the same “feel” as the concept.

My guess is that the ELR will debut about the same time that the Gen II Volt comes out around 2015 and that the base price of the Gen II Volt will be around 30,000, (hopefully less), so that there will be a clear distinction between the pricing of the two cars. Way to go GM!

    A logical step forward, although surprised they didn’t just rebadge the sedan (which could still be done later). Gives hope for a future 2-door Volt, too.

    Cadillac had to have this car in my opinion. I couldn’t even fathom how there was any doubt on GM’s behalf to make this car over the last 2 years. This is such great news to hear they are finally making it official and bringing this car to the Cadillac stable.

    I hope the rumors of more electric range and performance hold true, and that they don’t stray from the mesmerizing concept car. The temptation will be to “cheap out” and offer a deluxe edition of the Volt. I don’t think $55,000 is going to achieve the vehicle we see as the concept car above. I don’t see the harm in pricing it at $60 or $65 and delivering the masterpiece concept car. People that buy Cadillacs already drop more than that for the Escalades etc. This is an exclusive car for an exclusive customer. If GM offers the concept car, they’ll have a winner on their hands IMO.

    Well a cadillac CTS coupe is MSRP starting at $38,365 according to the website (http://www.cadillac.com/2011-cts-luxury-coupe.html), so the “below the $57,400 Tesla Model S” price seems possible. Though it probably will be higher. I shure hope they don’t dumb down the Converge design shown here (at least not too much) for the ELR.

    “Performance was estimated by this same reported insider as being at least as fast as the Volt, with more all-electric range.”

    This seems like a bit of a non-starter for Cadillac buyers, IMHO. 0-60 in about 9 seconds is not Cadillac territory. I sure hope this ‘insider’ has his rumors reversed. Hopefully it really means: Performance estimated to be substantially faster than the Volt, with slightly less all-electric range.

    I don’t know how hard this would be, but if GM could work the clutches and use Fisker-like sport mode (using electric AND engine at the same time), they could probably lay down 300HP and 500+ ft/lbs of torgue. Now THAT would be a Cadillac!

    One large thing GM needs to consider is to get rid of the old. The 3 letter scheme with CTS, XLR, ELR is hard to tell what model you have. It takes the fun out of the car. My first car was a Cadillac Seville.

    One of the thing that made Cadillac great is the nice names it put to its cars. I think Cadillac should keep this as the Converj. ELR just sounds too cheap for the first Electric Cadillac.

    I’ve been thinking how this car will operate.
    Here is my guess:

    1) approx the same kwh pack only w/ higher C rate batteries w/ longer cycle life. so if the Volt is running around 7.0 C rate now the C rate could easily be doubled to 14. This would allow an off the line main traction motor of 220 Kw…probably w/ a small upgrade to the existing 110 kw unit. So off the line the car is in pure series mode (mechanical link not engaged). The ICE is started and ready to go but not supplementing power yet.

    2) as the ELR accelerates, at around 50 MPH or so we go into “mechanical link mode” and get that Cruze turbo motor supplementing battery power. How many HP is the Cruze turbo motor??–140 HP I believe so now we have 220 Kw electric PLUS 140 hp (104 Kw)=324 kw of power available to accelerate this vehicle.

    Sounds good to me.

    Anyone else want to speculate on how GM will hop up their Voltec drive??

    It is interesting that Model S price is mentioned, rather than Fisker. BTW, S will be much faster than the 9 sec Volt – so I can see ELR finding it tough to compete with S.

    By the time ELR is released, there will also be the BMW i3 (with an optional range extender) to contend with – though i3 is B segment rather than the C segment Volt size.

    Yes!!!
    This is the car to have.

    Knowing the current design trend of this department, the ELR will have no problem one upping the Volt. I hope that Volt off the shelf parts are not used. Weight reduction will demand light weight materials, perhaps even magnesium alloy components. No real structural carbon fiber, not even the token stuff as the weight problems come from the number of components under the hood more so than the exact material. The climate control, handling, acceleration and ergonomics improvements will require some simple redesign work that GM will have no problem asking for and getting.
    After that the sweat starts building up when the power demands start showing just how much ICE and battery will be needed.

    First and foremost; How much battery and how much ICE?

    The 1.4l ICE is already very compact. Adding the turbo might not be rewarding enough for fuel economy and performance. Tweaking that motor for peak torque, not hp, without adding weight is the way to go. Perhaps whether or not this motor might not be smooth enough to go without a turbo at peak efficiency is the design question that needs to be answered first. The entire geometry of the vehicle dynamics will be decided within the engine compartment equally with battery size.

    After the ICE, the real performance gain would be from deciding how large of a battery will be used. That will determine acceleration and hybrid fuel economy. The algorithms needed to determine the intent of the driver will be even more important and will add significantly to the gazillion lines of code used now. For example, if the driver uses the ELR as a sports car, the range will need to be reduced right off the bat to compensate for the need to accelerate often and quickly. The ICE will be used, not so much to keep the generator working directly with demand of the drive motor, but to maintain a significant reserve much as mountain mode does now to keep from going into the reduced performance mode. What type of performance will be priority #1; energy economy or traditional acceleration?

    Now that Bob Lutz got his way, just how much will GM get right with this car is the real anticipation. I wish these re-purposed engineers luck. Outside of GM, this is going to be sending a lot of engineers back to square one. If any designer thinks the Volt was tough to beat, this Caddie will make them think of a new career.

    Keep in mind that the Volt’s MSRP before rebates is less than $40K, so the ELR at $55K+ is quite a bit different. I’m in the camp that thinks it will have to be faster than the Volt with better handling. I’d like a nicer interior in the Volt but I wouldn’t pay $15K just for that. The Volt is also great on the highway at 70+ MPH. Not a ton of room for improvement there. Consequently I’m buying the rumors that the drivetrain is V1.5 with better battery tech that gives more power and more range. This would be easy to do. Where is statik when you need him? He as always wired in with this stuff.

    @evnow — How many people have actually gotten to test drive a model S? How many people had test driven the Volt a year before the production cars were released? Has Fisker delivered its second Karma? My point is that while I’d like to see Tesla and Fisker survive it looks grim to me.

    BMW is more credible but carbon fiber bodies are tres expensive, and, while BMW very much would like an EREV option, I wouldn’t expect one until 2015. From an engineering perspective a straight BEV is very simple compared to an EREV. I suspect the first i3′s won’t offer the option.

    As a “2+2,” the ELR will, like the Volt and Ampera, fit two people up front, and two in the rear seats. It will be about the same dimensions as a Volt/Ampera.

    As a Cadi; I would expect roomier dimensions; like: head-room, back-seat leg-room and an accommodating trunk/storage to haul around your E.L.R. custom luggage. In other words; the Volt dimensions really need to be stretched to be a Cadi IMHO. P.S. Having an optional induction 240v charger for home charging while keeping the plug outlets for other charging would make some people very happy as well.

    It would have to be a major redesign to to enlarge the dimensions of the Volt/ELR, perhaps even a different platform. Its not easy, you have to accommodate a battery pack and a fuel tank.

    My guess that Volt will come down in price by then, due to the new battery.. so perhaps the Volt will start at 35k and the ELR at $45.. before leather and wood trims etc.

    My hope is that the ELR looks closer to the concept than to a Volt.. but I have my doubts. The concept looks like it suffers from a lack of headroom.. then again Lutz took a drive in it and he is a tall fellow. I like that Coupe look..

    Power will have to increase and that will require a new battery.

    Noel Park: I long for the Voltec small pickup truck.

    Placing a more powerful genset/battery/motor in the Caddy will enable reuse in a (somewhat) larger pickup as well.

    What’d be nice is if they used a small V-6 to reduce harshess and vibration and increase torque. A V-6 would enable towing plus a good-sized payload in a pickup application and awesome power in a sport wagon/sports sedan/sport truck. Something like a Ridgeline or SportTrak but with Chevy looks. The 53kw genset raises a lot of possibilities for V2H and jobsite applications. 4×4 would be a plus.

    What’d be cool as well would be to turn the thing around into a mid-engine with the fat end of the ‘T’ battery in the front. A RWD/IRS like Fiero or Solstice or Z4. Make the seats structural with the petals+controls moveable.

    This Voltec platform has so many possibilities that the entire GM line-up could be based on the basic building blocks.

    With ELR in the lineup, Electras and Ampalas are not far down the road.

    If you say as independant companies I might agree – but both their futures (esp. Tesla) is very secure. Afterall both Diemler & Toyota think Tesla has valuable technology.

    While nobody has driven a model S – they have some 3,000 people who reserved one having paid $5K. I think that shows very significant interest.

    Ofcourse, Model S is a significantly larger car. So the comparison is kind of moot.

    Real EREV isn’t very complicated. Just use the engine as a true generator. While the erev option might come in later, I don’t think it needs to be all that complicated.

    Every 4-banger I have ever encountered has more vibration than a vee layout engine. Even with balance shafts.

    BTW. A girl (well,.. woman. Anybody less than 50 is a ‘girl’ to me.) in my office that currently drives a CTS knows about Converj. She didn’t have a clue about Volt or the technology. (Although when I showed her a pic of Volt, she thought it was ‘cute’.) She just likes the ELR for it’s body. Apparently, Cadillac sent current Caddy owners pix of the concept back in 2009.

    Beautiful styling but you all forget that the Volt is a very small car. I think making the Cadillac electric the same size as a Volt is a big mistake. These buyers at those prices would want more room.

    evnow: Real EREV isn’t very complicated.

    Volt *is* a ‘real EREV’ (I guess you mean serial hybrid.) until the engine is engaged via the third clutch. It seems to be fairly complicated to me if it needs 10-million-lines-of-code to operate.

    With a BEV, you wouldn’t need all the juggling act to tip in the engine smoothly.

    What I really like about the Volt design (as a pure EV) is the combination of MGa and MGb creating a ‘transmission like no other’. With a single-gear, single-motor design, you hit the rpm limit before you hit the (non-limiter) max MPH.

    Yes I’m talking about – serial PHEV and EREV as a concept rather than a marketing term. It doesn’t have to be complicated at all – a simple genset that comes on when needed fills the battery. Have a manual override switch to turn it on or off. End of story. i3 is not trying to do what GM did – a lot of us like that simple approach – infact thought GM would do in the beginning.

    Every Lexus is built on the same line as standard Toyotas… change and add things then charge $20K more …. same thing for Acura… your paying for expensive additions to a standard car.

    George S. Bower: I’ve been thinking how this car will operate.Here is my guess:1) approx the same kwh pack only w/ higher C rate batteries w/ longer cycle life. so if the Volt is running around 7.0 C rate now the C rate could easily be doubled to 14. This would allow an off the line main traction motor of 220 Kw…probably w/ a small upgrade to the existing 110 kw unit. So off the line the car is in pure series mode (mechanical link not engaged). The ICE is started and ready to go but not supplementing power yet.2) as the ELR accelerates, at around 50 MPH or so we go into “mechanical link mode” and get that Cruze turbo motor supplementing battery power. How many HP is the Cruze turbo motor??–140 HP I believe so now we have 220 Kw electric PLUS 140 hp (104 Kw)=324 kw of power available to accelerate this vehicle.Sounds good to me.Anyone else want to speculate on how GM will hop up their Voltec drive??

    I remember someone saying that the Volt motor is capable of 1,000hp… I can see the ability to tap the battery for a few seconds to unlease a lot of this power in short bursts…
    I also heard that GM has hired back drivers at Milford … seems a lot of testing is going on these days with the cash brought in from improved sales last year…. I’m sure a lot of cool electric drive testing is going on at GM…. the Volt is proving itself everyday with thousands of cars on the road… with the improvements completed at the Volt factory many more to soon be delivered.

    Give the ELR 200HP and I’m interested. Even if this means just 33 miles per charge. An ELR with 149HP is simply a luxury Volt. And I agree with others here. Leave the rear of the ELR concept car the way it is.

    Not remotely possible to have it be “simple” and “good”. The reason the Volt isn’t a straight serial is that the genset doesn’t produce enough power. You can get sufficient average power but not the needed peak power.

    The fact is that a straight serial design simply involves many unappealing drawbacks. BYD has a straight serial. When the battery is depleted you have to put ear plugs in and be prepared for more vibration than you’d get in a bad hotel room. We’re talking about BMW. It can’t can’t sell a car that can’t get up a hill or accelerate once the battery is depleted, nor can it sell a car that sounds like there’s a jackhammer where the engine should be.

    You seem to think the term EREV is just marketing jargon. It’s not. An EREV is a serial hybrid on steroids.

    At last, an EREV for the high end; which can potentially make GM some profit (and give them an appropriate place to hang those fancy cockpit gizmos to their hearts’ content. As you may gather, I won’t be buying it, but many surely will).

    The big news in this is that the Volt is freed to become “everyman’s Chevrolet,” as originally envisioned (“everyman’s Chevrolet” as in less expensive).

    The one exception to this mainstream Volt philosophy might be the ELR’s greater AER. Maybe a future Volt will offer it’s pack as an option (PLEASE not as part of a luxury package!!! That’s what the Caddy is for. With the same performance as today’s Volt, this should translate into even greater range. GM should recognize that when it comes to AER, quantity has a quality all it’s own; and leave the badges and cues alone).

    The Volt is great, but I agree with several others here that it would be considered under-powered as a Caddy. Here’s a thought … just add a second Volt motor and controller (already perfected) to power the back wheels. Less need to re-engineer things, and a 300HP AWD ELR would take off like a silent rocket. :-)

    What I really like about the Converj (sorry Cadillac, you should have used the name “Converj” for a Buick version instead if you intended to use “ELR”! yuk!) is how it can allow the Fisker Karmer to still maintain it’s edge in price without directly competing against it.
    The Karma has 4 doors and an equally beautiful body. The price of the Karma matches the cost of the components for a low volume privately owned production car. The Cadillac can easily undercut the price and offer more advanced technology at a better price as you would expect from an international manufacturer.

    The further away from the Volt and the closer to the Karma, the better.

    The Karma uses a serial drivetrain and the GM 2.0l turbo motor. Which motor should Cadillac use? The parallel/serial drivetrain trumps the Karma there. Perhaps the 1.4l turbo motor would be best.

    The 2+2 vs. 4 doors means that the Cadillac, by default, will have a greater range than either the Volt or the Karma. So, should the Caddie bump up the Voltec battery capacity to match the Karma? Piece of cake to add the cells but what about the weight?

    And which car will have the greatest driveway appeal? How can you put the ELR in the same row as the Volt and the Karma without any apology whatsoever?

    And Don, this is for you. Don’t ever, ever, give anyone the impression that a Cadillac can even come remotely close to sharing a bolt with Chevy. See how the Buick Verano is different from the Cruze? Even Toyota knows that differentiation. What Prius components are shared with the first Lexus hybrid? (Well, actually, the Lexus is indeed a Toyota in Japan, just not a Prius!)
    The lessons learned from the Cavalier/Cimarron disaster are still on a blackboard somewhere at GM.
    I’d rather associate the ELR with a world standard above the Chevy and leapfrogging past Lexus.
    Why not target the cache, exclusivity, technology, performance and the k(K)arma from Fisker?

    Never been a fan of steroids ;-)

    A simple serial hybrid that doesn’t need to take you @ 80 mph over the steepest mountain passes is good enough for me. It doesn’t have to be an ICE car & an EV. Just use it to make the last few miles or to overcome strange phobias like range anxiety.

    i3 will be a simple range extender with enough EV power. Just need to start the engine earlier if you need reserve power – and in any case it will just have enough dyno juice to go another 100 miles.

    i agree with a previous poster that gm did have to go forward with the converj concept car. it appears to me that a luxury hybrid segment of the “erev” sort (or whatever marketing terminology you choose to use) is developing with recent product announcements, so gm needed to have a product to announce for that market segment.

    how the voltec 1.5 platform will work is an interesting question. as to your suggestion that the power output of the traction motor be doubled; it makes sense that they would need to do something toward that objective since i would imagine that the elr will be a heavier car than the volt. given that there are limitations in the current generation of voltec technology, i suppose that that might help explain why gm wants the elr to have the approximate dimensions of the volt (although from the pictures the converj looks like a bigger car). the problem with increasing traction motor output is that it would reduce all-electric range and one of the stated goals is to increase all-electric range in the elr relative to the volt. maybe they will use a substantially larger battery or maybe advancements in technology will allow higher energy density…

    one possibility that they could implement to achieve improved performance (although i very much doubt it but i’ll just throw it out there as speculation) is one that would be similar to the “sport” mode that is implemented in the fisker karma, where the ICE helps generate power to supplement the power output from the batteries, thus allowing the traction motors to operate at higher output. under this scheme, the elr would have multiple traction motors and a higher output ICE/generator. while you might get better performance, a drawback that comes to mind is that the ICE would be running more of the time, at higher rpm and at higher noise levels relative to the volt.

    George S. Bower:

    Try to visualize the ELR/Converj as a real production unit. In that, scratch the HUGE 22″ Wheels of the concept, and visualize 17″-18″ wheels with much larger spaces between body and tire. Then scratch the larger-than-the-video-display-at-Cowboy’s Stadium Caddy grille, and make it a bit larger than Volt’s faux grille for brand identity, but much less gaudy. Now we have to pretty much toss out the entire whiz-bang showcar interior ( remember the odd retro-Jetson interior of the original Volt Concept? ). Designers can be flagrant with blue underlighting and fake LCD displays when they’re mocking up a show car – it’s all about “WHOOEE” appeal and photographs and not at all about functionality or reality in any way. In production ELR expect a cross between a Buick Verano interior and Volt’s center stack with perhaps a one inch larger display. The increase in quality perception will come from some slick metal, faux wood and/or carbon fiber inserts. It would be nice to see a fairly accurate interpretation of the seat design, which is actually very nice with Cadillac design language tie ins.

    It makes sense GM finally pulled the trigger on Converj since Fisker has gotten it’s headstart and will turn a lot of heads. Tesla’s Model S seems less “competition” since it’s an entirely different type of car being and EV, larger and a four door with a “third row” and hatch. The guys at GMauthority.com have a pic up of their idea of a Converj 4 door. To me, that makes much more sense as the market for Caddy coupes is relatively small and ELR’s niche would seem to be marginally smaller. ELR appeals to mainly upscale or climber types who want to be percieved as successful AND environmentally concious. Professional, corporate women would be a target – since style and conscience over performance would fit nicely into their priorities.

    To me, the Volt pushes all the right buttons. The smarter side of me only wants the drivetrain to be cutting edge and believes all the electronic doo dads only make the simpler parts of a car complex and create problems for us future owners. The gadget nut-smartphone owner part of me loves the idea of inductive charging in the garage, a charge-pad for my phone in the console, GPSeverything and the whole nine! In the current Volt, my gadget guy gets stroked, yet it’s price is realistic yet with plasticky interior bits and a rear passenger area akin to a ’90s Kia – but that’s OK… I don’t want to pay $20k for some leather door inserts, video displays for the rear passengers and loads of complex technogizmology.

    There is a customer out there for ELR. They’ll gush at self-park control and lane keep assist. They’ll want a heated steering wheel and voice activated sunvisors. They’ll feel smug going all electric, even though they paid enough bonus over a Volt to buy gas for a CTS-V the rest of their lives. I just don’t think there is A LOT of such customers. I could be wrong. There are too many big Mercedes and lunker Lexi out there sporting hybrid-assist – it makes zero sense to spend such a premium to get an extra 7 mpg from a car so decadent…but… I am certain the ELR would have a larger market if a four door version were offered – to that, there is no doubt.
