Caterham has the Superlight R300, R400, R500, and now the R600. One of these is not the same, though. The new R600 is Caterham's fastest Seven thanks to the first production supercharged model, boosting it to 275bhp from the two-litre Ford Duratec engine. This awesome little racer will cost you $72,00.
