Endurance Races With Electric Cars

after you run out of battery (this was accomplished after about 10 laps around Grand Valley) the car slows down to around 50 mph when the engine is making the same amount of power that it puts out (this car makes electricity by braking). I haven't tried them yet, but it seems odd that the concept car has more performance points than the rest of the GT's. Seriously? In a car with one gear??
