0-100 in about 4sec. A new generation electric car

Today we had a very interesting presentation at our office. Representatives of Tesla Motors came to talk about their prototype of an electric sports car. It is an amazing car, having an acceleration better than most sports cars, but a consumption of only 2 litres/100 km (if you translate the cost of the used energy into fuel costs). It is fully electrical, so you charge it overnight or at any energy outlet, and you can cruise for about 400km. After the talk we went downstairs to get a real look at the car, and it was even better than expected. I am convinced that this is the future...
