Green GT's All-Electric Supercar Unveiled 196

Posted by kdawson
from the hoping-bugatti-picks-up-this-tech dept.
Mike writes "Swiss auto company Green GT recently released the first details on a svelte all-electric supercar that is being heralded as the most powerful electric race car ever built. Designed with the 2011 Le Mans race in mind, the Twenty-4 will boast a sleek carbon fiber chassis and twin 100-kw electric motors totaling 400 hp — enough to push the vehicle from 0-60 mph in 4 seconds flat, and to a top speed of 171 mph. GreenGT's head engineer Christophe Schwartz has stated that 'The GreenGT Twenty-4 design study could become our 2011 Le Mans Prototype electric racer, or it could even become an electric road-going supercar. There is a possibility to do both!'"

    What interests me is how they'll power the car in a 24-hour race. There don't seem to be details on that.

    According to their site, there's a large solar-powered charging station (100 square meters of photovoltaic surface) which can be used to charge the car between races, but unless they're seriously loading the thing with batteries, they're either going to need long pit stops for charging or the ability to swap out battery packs as fast as other cars can pit for fuel.

    On the other hand, with their target date two years out and the rapidly evolving electric car scene, I wouldn't be surprised if there was some hot new prototype hitting the car show circuit around then that blew their doors off.

            • An electric car will do pretty well. It can provide a good weight to horse power ratio. One of the challenges in electric cars, is battery life. Discharge a lead acid battery more than 10%, and it's life goes from years to weeks. In a race, you don't care about battery life past the race. And with some engineering, a battery swap could come down to a reasonable pit stop.

              But the sex-appeal of something that does not rock the stands, or throw a flame is really low.

          I saw a f1 team roll a new nose cone on a trolley. It would probably be much easier to develop a trolley to swap out the batteries in one motion. First trolley grabs the batteries and moves them out of the way, second trolley with the new batteries rolls up to the side and slides them in. Sure it probably can't be done right now this very minute, there would be problems to overcome, but c'mon, a battery trolley with rails is beyond human capacity? (no pun intended).

      Done right, I can see a mechanical battery change process... Much faster than gasoline fuel.

      1. Pull up to red line.
      2. 4 clamps grab wheels
      3. car is left up in the air 2 ft, while spent batteries fall out, exit passenger side on conveyor belt.
      4. new batteries come in at same time, put in proper position.
      5. Car drops, latching in new batteries
      6. clamps release wheels.
      7. 0-60 in 4 seconds.

      I could see a see a 4 second pit stop here.

      Skip the 'lifting' process, and have them drop into a recess and you get rid of the GForce limitations on the driver. But you also make it so the system is embedded in the ground or the driver goes up/down a ramp.

      Then again, remember how they want to shoot microwave power from space? Imagine if your power is beamed to you from the center of the track. (sounds dangerous)
      And then instead of restrictor plates, you get resistor plates.

              Even racing supercars don't come close to running at 100% throttle nonstop -- and when they do slow down for turns, regen puts power back into the pack. Li-ion regen in the Roadster, for example, is around 65-70% efficient if I recall the numbers correctly. So you only lose 30-35% of the energy expended on an accel/decel cycle; the rest of your losses are primarily aero and rolling. Aero, which should be the primary loss mechanism, will depend heavily on how much downforce there is.

              I agree, though, in that it's probably not practical for the race unless the pit stops are long.

      How about Supercapacitors [wikipedia.org]?

      • If the car stores enough energy to run at full power - 200 kilowatts for one hour, that's a lot of energy you need to transfer in a short time. To transfer everything in a 1 sec charge = 720 Megawatts. 10 seconds charge = 72MW. 100 seconds charge = 7.2MW.

        Even if you halve the power to 100kW (say the car only goes 50% power on average), those are quite big numbers. Who wants to be sitting in the car while 36MW flows into it?

        The transfer is unlikely to be 100% efficient so there will be waste heat generated.

        Ahhh grasshopper. You are confusing horsepower with torque. A diesel engine with 100hp can create hundreds of pounds of torque. Horsepower doesn't tell the whole story and is not representative of how much torque the engine can produce, which varies with engine speed. A typical car has a torque curve that starts out gradually climbing and then reaching its maximum around 3000-4000 rpm (just an example here people) and begins to flatten and decline towards the red line, say at 6000 RPM. That means that this engine is only outputting peak torque at the maximum point in the curve. An electric engine has a purely linear torque scale. At 1 RPM it is generating 500lbs of torque. At 6000 RPM it is generating 500lbs of torque.

        "The torque of an electric motor is independent of speed. It is rather a function of flux and armature current." - Wiki

        Coupled with a continuously variable transmission (ala Prius) electric engines are both highly efficient and insanely powerful. If we can get past the hurdles of energy storage, which clearly dominates this discussion, then internal combustion engines will start to look as antique as the coal fired steam engine. I mean seriously. Which is more elegant, a giant motor, a shaft of metal surrounded by magnets and a coil of wire which is like 95% efficient or an insanely complex machine made of thousands of moving parts and components, which including a whole lot of small motors is only like 23% efficient at best? Never mind all the crap you had to go through to get the fuel that only yields 23% efficiency. Oh and forget about the terribly messy process of getting some black tar that was supposed to probably stay in the ground for a few million more years to cook down and refine into gasoline. (And people wonder why they haven't been building new refineries in the United States, maybe those people should have one in their backyard) I mean geez, solar panels are starting to exceed those kind of numbers already.... To hell with spending money on how to suck out the last few drops of oil from some sandy shoals. We should be spending all of our money on figuring out how to cleanly produce electricity. Our very future depends upon it in more ways than one.

        Hmmmmmm....now where do we have a huge source of energy close by?

      You hit it, the cooling is for breaks and tires, as well as down pressure.

      Every once and a while in the NASCAR races they'll show you a camera view from inside the wheel well. You can see when the driver hits the breaks the rotors literally become red-hot from the friction of trying to slow the car down.

      Now imagine that same situation, with wider tires and faster speeds on tracks with significantly more braking.

      Odds are though, that the frame they are starting with is from some company that produces frames for indy or some other circuit cars. Just as the Tesla Roadster is actually a Lotus frame and body. So the cooling requirements will likely vary significantly from the function of the imaged vehicle.

Of course assuming they use some form of regenerative braking the load on the brakes should be reduced which brings us to:

      2) Electric motor cooling. 100kw electric motors will get quite toasty if not cooled.

    • Actually, since they are shown in both up an down positions, my bet is that they are air-brakes, supplementing the regular braking system.

        Aren't variable aerodynamics banned, though?

        • There have been cars with air brakes in the Le Mans before (in fact, they were introduced there), although the rules may have changed since then. And depending on the exact definition, air brakes may or may not count as variable aerodynamics: They intend disrupt the aerodynamics, not change it into a new form.

    0-60 in 5 seconds and top speed of 171? that's about the same performance numbers as my family sedan (a chrysler 300C SRT-8) which is DECIDEDLY not a supercar! i did not know my 5-passenger luxury sedan was a viable candidate for lemans.

      Whatever it is, you probably couldn't race one "continuously" for 24 hours and I about guarantee that it handles like dogshit compared to an actual LeMans car.

      • by pezpunk (205653)

        do lemans cars get pit stops? if so i see no reason it couldn't. handling, of course, is about what you'd expect from a 4000lb car.

        but my point was 0-60 in 4 seconds and 171mph is not supercar territory, unless this is 1986.

          The acceleration is fine; most supercars do not have the best possible acceleration because it would interfere with top speed (e.g. gearing issues.) The top speed, however, is less than 200 mph, which is pretty much mandatory for a supercar today.

      Until you try to corner with you little bus. And it was 4 sec not 5.
  • 1) They are way underpowered, even compared to the 2008 front runners.
    2) There currently is NO electric car class at all
    3) LeMans is by "Invitation only", not just anyone can show up and race.

    ~2008 specs for the front runners:

    Audi R10: 650 hp-1100 Nm-925 kg
    Peugeot 908: 700 hp-1200 Nm-925 kg

    171 mph top speed jumps out at me as very uncompetitive at Le Mans. The Circuit de la Sarthe [wikipedia.org] is a long track with a lot of straights, especially the Mulsanne Straight. Last year, the cars in the GT2 class which I assume this will compete in (the slowest class) topped out at 182-186mph for the most part.

    "...the most powerful electric race car ever built."

    Maybe for a certain class of race car, but The Buckeye Bullet [buckeyebullet.com] broke 300 mph years ago, and the new model will have been tested before this Green GT car is built.

  • I haven't followed the research closely, but it seems like the majority of stories are about high-end electric race cars when the real money would be in much more modest family sudans or commuters. I'd love to see an endurance racing challenge where manufacturers had to hit real-world benchmarks (hauling around mom, kids, and groceries equivalent in weight for X miles or X hours).

      Every 15 minutes the driver will have to announce whether or not they are there yet?

  • If EESTOR was for real AND has produced prototypes, now would be the ideal time to bring it out for use. Put it in a decent car and see what happens.
  • twin 100 kW motors = 400 HP?

    What an idjot.

    This is actually about 268 HP.
