BMW Vision EfficientDynamics Concept unveils as we speak and car fans are already raving about it. The new Vision Concept is was designed with the EfficientDynamics approach in mind, and while many expected to see a supersports car, BMW has prepared for us many surprises.

We’ll try to keep this short and to the point, but expect a more detailed review and lots of information in the upcoming hours. The BMW Vision EfficientDynamics is an exciting concept and it deserves our full, undivided attention.

So, let’s take a look at some of the facts that we gathered and we believed are impressive.

    whats with the rotating front grill? does it really allow a substantial amount of extra air flow?

    and notice how the rear wheels are subtly placed wider than the front, much like the concept we saw earlier on where the back wheels were completely unattached from the main body and had their own mud guard like covers. This must be due to motor and the electric motor.

  • viper

    seriously those are nice facts!…..will never come to life though

    • L1ndja

      Believe me they will…And that very soon. Im fascinated by the way,this is the coolest concept ever build.

      • wazon

        Agree, technology applied in this concept will appear soon in production models, however I’m not sure about car itself. Hope that it won’t share sad CS’ fate and indeed will go to production.

  • Mauro Corti

    @Nick

    Considering there is no cooling fan in this car (not even one), an extra air flow is crucial.

  • Mauro Corti

    @ L1ndja

    You say this car will come to life because you believe it or because you know something we do’nt know?

    • L1ndja

      hahaha probably not much more then you but there were a lot of rumors for a green supercar and it would make real sense so its more that i believe it.

  • Doug

    “No active cooling” might need some clarification; does it refer to a specific component (engine, battery, electric motors, a/c), or all of them? Does it mean that there are no cooling fans or coolant pumps anywhere?

      Here is a quote from one of my friends:

      “No active cooling refers to Li-Poly battery complex only. Since the energy management is so efficient, batteries do not heat up to a level requiring active cooling.

      All the other systems (engine, AC, thermo-electric generator) still have active cooling systems. “

  • A R Ansari

    It will be a tough competation for the Audi R8, I am really happy and BMW is the Best and it rocks

  • Shawn

    Doug, as I understand it this lack of a cooling system refers specifically to the batteries/hybrid drive system and nothing more. This is significant as the cooling systems on current hybrids account for great space and weight penelties. The diesel will have standard cooling systems – though it will no doubt feature an “on demand” electric cooling fan as is already standard on some new products. Not sure if your question has already been answered elsewhere! By the way – that’s one Hellofa Diesel!!! 1.5L I-3 Turbo with 163 hp and 214 lb-ft of torque!!! What a MoNsTeR!!! The specific output would equal 326 hp and 428 lb-ft from 3 L. A notable improvement over current spec 3L BMW diesels.

    My biggest concern/fear for BMW’s new hybrid drives was it’s batteries. Nickel Metal Hydride batteries are antiquated and do not belong on a BMW. I was very dissapointed to learn of their use on current BMW Hybrids such as the new X6 hybrid (though still the most powerful hybrid in the world!). On the positive, it looks like BMW’s partnership with SB LiMotive (a German/Korean company backed by Bosch and Samsung) is yeilding awesome results as the VED concept is powered by Lithium Polymer battery technology – the very latest and greatest in battery tech.

    Here’s why the VED concept’s use of Lithium Polymer Batteries makes be SO EXCITED and IMPRESSED:

    Compared with nickel–metal hydride batteries, lithium polymer batteries deliver the same power with 30 percent less weight, 50 percent less volume and 10 percent greater efficiency over nickel–metal hydride batteries. Lithium polymer batteries offer more than twice the energy density of nickel–metal hydride batteries, and 175 percent greater volumetric energy density, meaning BMW engineers can devote less space and weight to the battery pack, and have better placement resulting in a lower Center of gravity, 50/50 balance, etc.

    Lithium polymer batteries also hold their charge 20 times longer than NiMH. Lithium polymer batteries are more resistant to changes in temperature, which improves cycle life and makes them better suited for use in extremely Hot or Cold climates. Lithium polymer’s self–discharge rate is less than a third of a nickel–metal hydride batteries (meaning you can let your car sit for 66% longer without loosing your charge). Lithium polymer is more resistant to physical damage since the functional unit of the battery consists of a polymer Gel instead of liquid. This allows for thinner walls housing the gel made of aluminum, instead of the thick and heavy protective metal walls of a NiMH battery. Lithium Polymer batteries can handle more charge–discharge cycles before storage capacity begins to degrade. Lithium polymer technology also offers significant advantages in safety compared with typical lithium–ion batteries.

    Obviously, this is a triumphant announcment by BMW and I am ecstatic at the news!!!

    There are many good things to come in the future of BMW Efficient Dynamics.

    Of note, Hyundai motors is acutally the first to use Lithium Polymer battery tech on their new Hybrids though their cooperation with LG of Korea. The above technical specs are from Hyundai. I’m noticing a trend here… Korea is leading the world in battery development!!! Again, it’s great to see BMW partnership with SB LiMotive!

      Shawn, that’s interesting. The Tesla’s battery unit is water-cooled, isn’t it?

      Actually, I had the same thought about NiMH a year ago when Ford announced their plug-in suv hybrid and investment in that particular technology (that thought being: “nimh– seriously???”). But there apparently were good reasons for that in manufacturing, longevity and overall economics despite lower power density. Those specific reasons I didn’t manage to remember.

      Actually, one thing I do remember is that mechanical flywheels (particularly solid carbon fiber) so still theoretically have more power-storage “density” than any of the battery technologies, hence their use in space applications, power grid management and BMW’s apparently disappointing hybrid system.
