The Caterham Seven 620R, the company’s most extreme car yet, will be unveiled at the Goodwood Festival of Speed this weekend.

Powered by a new 2.0-litre supercharged Ford Duratec engine developing 311bhp at 7,700 rpm and 219lbsft of torque at 7,350 rpm, the 620R can sprint to 60 mph in under 2.8 seconds, topping out at 155 mph.

Replacing the Superlight R500, the 620R is available to order now priced from £49,995, with first deliveries expected later in the year.

Caterham F1 driver Charles Pic and Caterham reserve and GP2 driver Alexander Rossi will drive the 620R up the famous Goodwood hill.

A display car will also feature on Caterham’s stand elsewhere at the Festival of Speed.

Caterham Cars CEO, Graham Macdonald, said: “The 620R is the most hardcore production Seven ever built for the road.  The R500 claimed its place in motoring history as a benchmark for lightweight sportscar performance but this new vehicle pushes the boundaries even further.  While I wouldn’t necessarily recommend this car for those inexperienced in driving Caterhams, we always ensure that even our fastest cars retain the manageable delivery of power that makes them accessible, despite the daunting statistics.”

The 620R uses a unique gunmetal chassis, airflow-optimised nose cone and race-developed cooling.  Carbon-fibre interior panels and race seats, together with a Q/R race steering wheel, complete the look.

“The Seven 620R is an extreme piece of kit,” continues Macdonald. “We know there is demand for cars that re-write the rules of performance and, if you’re brave enough to take it on, the 620R will be an enormously rewarding, fun car to pilot.”

A 620S version, with identical power output but a little extra in the way of accessibility, will be launched later in the year.
