The most extreme of Caterhams to date, the 620R is the only exception to the rule because it is not sold as a kit car.
It is a supercharged version of the R500, which gives about 311hp on a car that weighs just over 500Kg. The result is 568bhp/tonne!
To put it in perspective, it’s up there with the Bugatti Veyron and the Pagani Huayra.
Match that with a manual gearbox and I think it’s every petrolhead’s wet dream.
