This car uses the 220 bhp RSX Type R engine and only weighs 500kg. The new limited edition one uses the same engine only supercharged to 300bhp. 0 - 62 in 2.9 seconds providing you can shift that fast. power to weight ratio of 600bhp per tonne, better than a Ferrari enzo.just found this interesting and thought you guys might too. It only costs £20000.

Yeh, they're crazy, although its a rull race car, its not like you can drive one on the streets. However you can drive a Lotus on the streets and get a K20A swap :D
