Green GT's All-Electric Supercar Unveiled

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!'"

24 hour charge??

[gbulmash]

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.

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.
