BMW Toyota Sports Car Rendering

The BMW-Toyota sports car is well underway and new details emerge every month. The new car was already confirmed by BMW chairman Norbert Reithofer and Toyota boss Akio Toyoda, and it’s scheduled to arrive in 2017.

BMW Toyota Sports Car Could Be a Real Shocker

According to Autocar, the two-seat sports car that will bring performance-boosting supercapacitor technology to a series-production model for the first time. It will also feature a front-engined layout and it is likely to be four-wheel drive thanks to the use of a direct-injection petrol engine and electric motors. These power sources will form part of a high-tech supercapacitor-touting hybrid system that draws on technology and expertise gained from Toyota’s Le Mans LMP1 sports car program.

It uses supercapacitors for short-term kinetic energy storage and a performance boost.

BMW and Toyota have chosen supercapacitors because they can absorb and discharge kinetic energy more rapidly than the latest generation of lithium ion batteries. They are also typically smaller and lighter than existing energy storage sources.

BMW brings to the table a powerful 2.0 liter turbocharged engine combined with electric motors produced by BMW at its engine plant in Munich to specifications supplied by Toyota. The engine is paired with a sequential manual gearbox. A Toyota-developed electronics system is expected to provide torque-vectoring capability.

Learning much from the i3 and i8 models, BMW will move some of those ideas into the new sports car.

The sports car will be one of a series of future BMW-Toyota projects to use common engineering solutions and shared components.

    Nice looking sports car. Wonder if it will have a high content of CFRP.

    Wait and see what Tesla will do with these capacitors. To start with Tesla does not have to push an ICE that is in the car. Also Tesla is going to build a Giga factory. It is not only going to be used to make batteries but capacitors too.
    It is already listed on Wikipedia a 480 wh/kg capacitor. That is at least 2 times more than the Li ion batteries. It chares in seconds and is not affected by tempreture and can be charged and discharged millions of times!
    Look for Quantum nanoclusters of dipolar metal oxides in TiO
    2 or TAO

      “To start with Tesla does not have to push an ICE that is in the car”

      No, it needs to push a 2-3x heavier battery instead.

      ICE+supercapacitor is the way of the future for high performance automobiles. You only need a few kWh (enough to get you up to your max speed) and 200-300 horsepower ICE (to maintain the max speed), and it can power even 2000hp motors for acceleration.

      “Look for Quantum nanoclusters of dipolar metal oxides in TiO”
      That Wikipedia reference is a 10-year old patent that has never been made a reality.

      The good news is that we don’t need that kind of density, because less than 5kWh is needed to hit 200 mph, and that energy can be released in seconds. So 50Wh/kg (exceeded last year) would need less than 100kg to meet all your needs.

    That rendering looks 100% BMW. It has seven BMW logos on it (eight if there is one on the back), yet I don’t see any Toyota logos.

    I could be wrong, but this resembles Toyota’s Tesla partnership. A partnership to hide the fact that Toyota is not really innovating beyond their Synergy hybrid drive.

      Toyota coasts on Camry sales.

  4. A///M5 says:

    lol @ the rendering, thats a freakin Z4 with mods LOLOL

    1. ELROY says:

      You might be correct. But a hopped up Z4 is not a bad looking car at all. One of the best looking cars on the Le Mans race series:

      From what I understand, supercapacitors make great short term, high cycle, storage solutions.

  5. Thomas says:

    “They are also typically smaller and lighter than existing energy storage sources.”

    This sounds very wrong if we are talking about energy storage. Their power density is great, but energy density is far away from real world storage, its more a short time buffer.

    The link in the article went wrong:
    http://www.bmwblog.com/2014/03/25/rumor-bmw-toyota-sports-cars-use-wheel-drive-supercapacitors/

    @Open-Mind There would be two pretty identical cars, sharing the same platform, but obviously one desgined for BMW and one for Toyota.

    1. Alaa says:

      This is not true. The energy density is very high now. It is more than Lithium batteries. At least more that what Tesla is using.
      Look for Quantum nanoclusters of dipolar metal oxides in TiO2 or TAO

      http://en.wikipedia.org/wiki/Supercapacitor

      There are many articals about Graphene and capacitors. Elone Musk was going to do his PhD in that.

      1. Thomas says:

        Those new developments are far away from series production. Graphene supercaps seem pretty promising, but that takes time and would still be about as energy dense as a NiMH battery.

        The 480 Wh/kg claim seems somewhat questionable so far and the wiki lists only patents as sources, pretty old ones actually. I would like to read more once it is more than paperwork and there is a working prototypes of that. That Rolf Eisenberg can’t even impress those EEStory guys: http://theeestory.ning.com/forum/topics/what-has-become-of-rolf-eisenrings-ideas

        1. Alaa says:

          I am glad you noticed that they are old patents. If anything this indicates that there is a hush hush agrement about this. This is a killer application, and I would not be surprised if the army is behind the hush hush thing! Most certainly there are people working on this subject and I would not be surprised if the 480 Wh/Kg is imporved upon many folds.

    Up in the air.. whats that? Its a Supercapacitor!

    Anyone remember Super Flywheels? That was a popsci favorite a while back….
