Frankfurt Report: The Opel Flextreme Diesel Concept

Opel Flextreme concept
The Opel Flextreme

By Bob Lutz
GM Vice Chairman

As I've said before, I'm more excited about the Chevrolet Volt than anything else I've seen in my many decades in the auto industry. This week in Frankfurt, we unveiled a European version of the E-Flex line, which we call the Opel Flextreme diesel concept.

Even before anyone discusses the technology, I really think the first impression the Flextreme makes is that it's a great-looking car. Mark Adams, GM Europe's Vice President of Design, told the gathered media that the Flextreme shows the future design language for Opel. Its monocab proportions fall in between the popular Astra and Zafira models, but as you can see, its profile is much sleeker. And when it's time to install a car seat, parents of small children will appreciate the rear-hinged passenger door. In fact, it's been so popular with focus groups that we are moving ahead with plans to put the FlexDoor system into production.

Like the Volt, the Flextreme is powered by an electric motor, with a small internal combustion engine to recharge the batteries if needed. In the Opel Flextreme, though, that engine is a 1.3-liter CDTI diesel. The car will be able to run about 55 kilometers (almost 35 miles) on one charge. Our research shows that will cover the round trip of 75% of European commuters. Once the diesel engine kicks in, the Flextreme will emit less than 40 grams of CO2 per kilometer driven, far below the proposed European Commission's target of 130 grams of CO2 per kilometer.

And, as an added bonus, two specially designed Segway Personal Transporters will fit in the Flextreme's underfloor compartment. This will allow commuters to park outside the city center and ride their Segway Transporters the rest of the way. In Germany, commuters in Bavaria and Nordrheinwestfalen, Saarland and Hamburg — representing more than a third of the German population — are now allowed to ride their Segways on the streets.

So we think the Flextreme concept, along with the Segway Transporters, can significantly advance clean urban mobility. We'd like to hear what you think, especially those of you in Europe.

UPDATE: Check out FYI for video of the Flextreme.

    Noel,

    But I think you’d have to admit that Opel’s lightning bolt logo also has a lot of “pop.”

    There is no doubt that GM is coming out with quite a few great cars but you need to do something about your dealerships. This week I started looking for a new entry level luxury car. I’ve been to GM, Mercedes, BMW, Infiniti and Lexus dealerships and I have to say the GM dealerships are by far the worst of the bunch. Either the dealerships are run down with tacky looking salesmen in $50 suites and/or the Cadillacs are mixed with cheap looking Chevys or Pontiacs and/or the Cadillacs have these big goddy wheels that only a pimp would want. How can Cadillac compete with the other luxury makes in this type of environment. Your products are good and getting better but for you to really compete the dealerships need to be repositioned and improved.

    Volt would be a hit with youth and middle aged man.

    while Flex would be a hit with families that have children.

    Bring bother over.Chevy& Saturn!

    While your at it,if producing more models lowers technology cost.

    Add a Buick or Caddy sedan model.

    Saab should be getting Bio-Diesel too.

    Bob and GM,
    Hope you read this. Comment on providing rear doors like in the Opel Flextreme (called Flex Doors) in production version of E-Flex vehicles. I really like the looks of Opel Flextreme and would prefer a hatchback design over the sport car design of Chevy Volt. Only would not like the reverse swing of the rear doors. Initially when I saw them I thought it was really cool and would want them, but after thinking about it and the possible impact on design complexity and saftety and ablity for vehicle to hold up with that time of door, my vote it no. Be sure to do full market analysis before providing a door like that in production. Focus on quality and strong, long lasting vehicles. Recommend provide a E-Flex with outside look like the Opel Flextreme but make the rear doors and rear hatch like the standard todays design. Better for the masses.

    With Alicia’s good help, I finally found my way into the gm-volt.com website.

    It is really informative. I highly recommend it. Check it out!

    Gary,

    Your hypothetical Silicon Valley dude might have a hard time finding the volleyball court at the RenCen, but he could use the one up here at the Tech Center in Warren. C’mon, we’re not as backwards as you think!

    BTW: Opel Watt?? What?? I’ll admit that I’m not too crazy about “Flextreme”, but Opel is heavily invested in the “Flex” theme.

    I just don’t understand why Europe gets the best car designs. Even Ford won’t release the Modeo. I think it is smart that have Saturn mirror opel. No need to increase costs by developing different models. Just design these world cars like BMW, Volvo Vw etc.

    I really think the Opel e-flex design would be a big win if the final product is a little smaller like the Prius. Onece it comes out why not offer a sports sedan e-flex and then a small utilitarian version of those cute Mini cars you had us vote on.

    Please don’t give USA the retro HHR version of the mini’s. Make it moder to compete with Smart, UP, and toyotas new Micro car concept. Retro is out! Modern is in!

    I think you have a winner. Bring it here and we will buy. But first you have to talk to some of the states, such as PA, where it is illegal to ride(drive?) a Segway on teh street, sidewalk, or even bikeway – since it is powered. My state hates electric scooters as well (unless you make them DOT-legal).

    Frank,

    Not backward, I’m just saying there would be a culture clash between GM HQ and Apple. I imagine one as being very conservative with a “We can’t do that. Why, we’ve never done it that way before.” with mid-level managers and executives needing to signoff on every decision, and where showing up in the correct three-piece suit is more important than a person’s ideas. While I imagine the other as being, “Why not? Let’s give it a try.” while giving the junior designers and engineers as much free rein as they need to be at the cutting edge of technology and style.

    Of course I may not be right, but that’s my perception — and I suspect others share that perception.

    However, I have a sneaking hunch the culture clash between the Warren Tech Center and Apple would be a lot smaller than the gap between the RenCen and Apple.

    Best regards,

    Gary Dikkers

    I guess I must be the total cynic when it comes to these things. First, I think it’s a lovely concept. For once, I think a GM designer came up with some that looks attractive. But I heave a major sigh because, well, let’s face it, this ain’t never gonna see production, gang. It’s vaporware, pure and simple.

    Have we all forgotten there’s not battery in existence to make this car a reality? It’s a nice concept, but like the Toyota iQ, it’s just a concept. We’ll never see it on our streets, in the parking lot at the local shopping mall (or in my case, parked on the street with the parking meter ticking down the seconds until the meter maid comes to give it a ticket while the owner looks frantically for an outlet to plug it in). A heavy dose of reality would go so far.

    And even IF the batteries exited, clearly GM has no intention of bringing in this car to American shores because it would prove what a fraud the rest of the lineup is. Mega sigh…

    Mr. Lutz, I believe that you are doing an excellent job! I can’t wait to own a volt.

    I do wish that you would go one step further and stress renewable electricity including home rooftop PV electricity. Focusing on the electric only range is confusing. Nobody wants a car with a “40 mile range”. Perhaps you can memorize a little 5 second sound bite on the mpg between charges.

    Example “According to statistics, 82% of all commuters travel less than 40 miles each day. During these commutes, the Volt uses no gas at all. When driving 100 miles, the Volt will get around x mpg, 150 miles equals about x mpg, 250 miles = about x mpg and when going the full 650 mile range on those really long trips, the Volt will get over 54 mpg”

    There has to be a way for you to memorize and then repeat this statement at every opportunity. It should be in every advertisement.

    Electric Range, MPG at different ranges, lower maintenance costs, longer vehicle life, greater drivability, lower emissions and a much lower cost of ownership during the X year expected lifetime.

    Stan, 9/14, 2:23 PM:

    I could not agree more with every point raised in your comment. Well done and thank you very much!

    Believe it or not bloggers, but my mother tried to raise me to follow the maxim, “If you can’t say anything nice, don’t say anything at all”.

    Thus, the record will show, that I stifled myself and submitted no comments on the recent post discussing the HHR SS, or whatever it is.

    Now that Stan has broken the ice, however, I am compelled to agree with him. HHR? You’ve got to be kidding!

    That looks pretty neat. I just saw that GM is making a 4.5L version of the Duramax. I hope they have the good sense to put that engine in the G8 and other cars with that platform. Heck even the CTS and a new rear wheel drive Buick would be awesome with that kind of engine… 300 HP and 500 Ftlbs… and good fuel economy… GM would be pretty foolish to not do that. Pair it up with a decent transmission (6 speed auto and 6 speed manual) and GM has a decent performing high economy car. Now to see if it actually happens.

    For those of you who haven’t done the research.

    The E-flex in the Chevy Volt can be configured to run on gasoline, E85, and biodiesel.

    And for the people above who are wondering where GM’s hybrid systems aren’t in passanger cars. GM made the decision to put them where they would do the most good. I.E. public transportation.

    BMW and the X6 state the case that the crossover is crossing over to the sedan segment.

    Let me tell GM exactly what I told them long ago (and you can check the record, ie. the blog) that the sedan is next in line for an SUV style high seat, high roof, command seating, a la the SUV.

    And BMW which is always 5 years ahead of the design curve is the first to do it with the X6. The first crossover with a coupe style hatch and four doors.

    What’s next? A similar conceived crossover with a standard trunk.

    All of this does not surprise me, it was only a matter of who would be first.

    I know development takes time and I know the market for the X6 is not proved and I know it is just a concept at this point but from the looks of things, just prepare to be dazzled once again by BMW who brought us the X3 and other ground breaking segments in the SUV arena.

    I know GM is making world class progress in design and technology with the Volt and Camaro and either one of these will shake the automotive world but there is that saying…

    No matter how good you are, there is always room for improvement.

    In this case it has a high roof, SUV style seating, four doors and a coupe style hatch in the back.

    Note a story today from AP, posted on Yahoo. I can’t quote the headline verbatim, but the essence is: “Hybrid sales up 49% in the US”.

    They report that this was led by a “boom” in hybrid sales in the Midwest, up over 50%!

    So much for latte drinking, chardonnay sipping, tree hugging left coast liberals!

    Good to see GM show the Diesel version of the E-Flex which should do well in Europe, this rounds out the options well with E-85 for the U.S. and Diesel for Europe with the potential of a Fuel Cell shown for Asia (if they go that way).

    I like your new ad campaign showing how GM is offering a wide range of vehicles from gasoline efficient to gasoline free. It is about time, I have been saying for over a year that GM is the ONLY major automaker that is doing something in ALL areas to improve fuel efficiency.

    Although you really need to fill the high MPG car market in the U.S. (this is made more frustrating by the fact GM already makes these cars and has made them for years).

    Getting back the the Flextreme, I have seen where the Volt maybe in showrooms in late 2009 (if all continues to progress as I guess it has been) with a “second” vehicle to follow shortly therafter. Will the U.S. get something along the lines of the Flextreme? I also heard that the Plug-in VUE will be available sooner than originally expected.

    Congratulations and I can’t wait to hear what all the doubters will say when the Volt makes it to market.

    Personally, I prefer the style of the Flextreme to the Volt, but there is a market for both.

    I don’t like the rear hinged doors. Like Fred, I think sliding doors (like on a minivan, only smaller) would be better. Or even regular hinged doors – B pillars aren’t that bad!

    The rear center post won’t do, and certainly won’t be in the final design, although the twin rear hatch butterfly doors were kinda neat.

    The Segways are too expensive to be a standard feature. Optional, well, maybe.

    @Nate,

    You can’t seriously think a 4.5L engine will provide good economy?

    I drive a Jetta TDI with an automatic transmission, which gets about 40MPG driving comfortably in excess of the legally posted speed limit. My girlfriend’s Prius gets 45MPG-50MPG under the same conditions.

    A car that only gets 35MPG seems pretty average, once you’ve driven these cars. Any passenger vehicle in the 20s looks like just an expensive nuisance.

    Now that you have some perspective on what “good mileage” means, I can say that I’d *love* to drive a vehicle with 300HP and 500 FT-LBS of torque that gets (just guessing) 25MPG (which would be great efficiency, from a physics perspective). That would be a wild ride, and could probably tow a heck of a big boat. But, don’t confuse a 25MPG sport-sedan/wagon with an efficient (from a social perspective) commuter and highway cruiser like the Jetta TDI or a happy-on-the-highway city-car like the Toyota Prius.

    EPA emission standards for a Volt or Flextreme with a diesel-powered generator set

    A question for GM to consider — if they haven’t already:

    Would a Volt or Flextreme with a diesel-powered generator set have to meet the same EPA Tier 2 Bin 5 emission standards a diesel-powered car would have to meet?

    The reason I ask is because there is a big difference: In a diesel-powered car the diesel motor is physically connected directly to the drive train and rear wheels; while a in a diesel-poweed electric, the diesel motor would only charge the battery, and is otherwise not physically part of the drive train.

    If a Volt or Flextreme with a diesel-powered generator set didn’t have to meet the EPA Tier 2 Bin 5 standards, that would give GM a lot more flexibility to use an efficient turbo-charged diesel in the North American versions of their electric cars.

    Best,

    Gary:

    If Honda is going to meet the EPA requirements with a diesel next year, it would seem pretty doable to do it with the size of an engine equivalent to the 1000cc turbocharged gas engine proposed for the Volt.

    The last rumor I saw was that the diesel was going to be the replacement for the failed Accord Hybrid. If Honda can power a car the size of an Accord, which supposedly meets the standards with a stand alone diesel (no e-flex, or equivalent), what’s the problem with a plug-in hybrid?

    Let’s not give these guys too much slack.

    Maybe GM should do what we always accused the Japanese of doing in the past. Buy a Honda diesel and reverse engineer it.

    By the way, I couldn’t help but notice the series of Chevrolet ads in the LA Times yesterday for the Volt, fuel cell Eqinox, and the hybrid Tahoe. Nice looking ads.

    Is the intent that we should be so impressed with Chevy’s good intentions that we run out and buy a current offering, or that we should wait for the plug-in hybrid or the fuel cell car? My decision is the latter.

  • Luke

    Clarification:

    On my response to Nate’s comments, I said that I’d love to drive a 300HP car. That doesn’t mean I’d want to own one, on account of the ongoing fuel-cost. I’ll own my efficient commuter / highway cruiser, and rent one of those if I want a wild ride for a weekend.

    There will always be criticism about the advancements that people/corporations make but the truth of the matter is right now at this very moment Bob Lutz should be applauded because GMC is currently leading the pack in terms of creating greener cars. The problem is taking fossil fuel out of the equation 100% and they have come the closest so far. It is a great design and is environmentally friendly. Cheers!

    Luke: The 4.5L Diesel will delivler more like 32 MPG in a G8, the 6.0L Gas engine should be rated close to 25 MPG if not 26 MPG.

    The 25 MPG figure is for GMT900 model Trucks and SUV’s.

    That represents a 20-25% improvement in MPG with little to no sacrifice in performance. That is impressive and if the 4.5L proves popular GM could offer a smaller 3.8L version with 250 HP.

    I would like to see GM’s new 2.9L Turbo Diesel in something stateside – the new Malibu? At least the 9-3.

    GM should have been brining Opels to the US 25 years ago. They just never figured any of this out. Japan could have been defeated in the 1980’s had they moved the cars of GM Europe to America.

    What in the name of god would I do with a 300 horsepower car that I can’t do with a 120 horsepower car that gets twice the mpg?

    My scooter has 9 horsepower, which is more than enough to get me to and from work on a daily basis and still get 70-80 mpg.

    I can understand why people who race or who tow trailers might want a huge engine. But I could never use 300 horsepower. I’d rather trade a few seconds 0-60 for a healthy improvement in fuel economy.

    Paul,
    Not everyone’s life is so spartan. Many of us have families–with children (maybe most of us) and live outside of the cities (no place to raise children).
    ———————-

    Mr.Lutz,
    I have got to bug you again about Cadillac–my favorite marque.

    1. Why is there no model-for model direct answer to BMW’s 3 and 5 Series (X3 an X5 included)?

    Can you imagine a Cadillac full of models as good as or better than the 2008 CTS? At the top of their respective classes?

    2. Are you all waiting for Lexus to invent the Bose Suspension before you all use it?
    It should have been in its third iteration by now, in a leaner, meaner configuration and coupled with Magneride technology.
    It should have been looking to go into the upcoming 3-Series competitor and all the SUVs.

    Gm needs to wow people again. This would do it hands down.

    Cadillac needs this.

    3. Why do you hate the SRX?
    The car was a hit with th e press. Make it look less “wagonny” and make it a stunner inside and out and underneath like he 2008 CTS.

    It will sell!

    That was the only thing wrong with it and everybody knew that!

    It is too good to put on Lambda (no way Sir!). Put it on Sigma 2!

    Love and respect,
    E.L.

    Dear Mr. Lutz,

    I’ll echo those US residents who prefer the Flextreme’s styling and diesel generator (which’ll hopefully handle B100) over the Volt’s styling and E85 generator. I also like the suicide, er, FlexDoors, though I hope the production rear cargo door will be more of a clam-shell (i.e. without the view-blocking center pillar).

    Please offer the Flextreme in the US, but without the Segways; either keep that compartment as concealed storage or just make the luggage space bigger. Thank you.

    Sincerely,
    Suman M. Subramanian
