Say hello to the mighty Caterham 620R. The new top-of-the-range model is set to make its first public appearance at this weekend’s Goodwood Festival of Speed.

Don’t let its unassuming looks catch you out – its supercharged 2.0 litre Ford Duratec motor produces 311 hp at 7,700 rpm and close to 300 Nm of torque at 7,350 rpm, making it the most powerful production Seven ever made.

As a direct result, the lightweight sports car can do the century sprint in a neck-snapping 2.8 seconds and is capable of a top speed of nearly 250 km/h (not with no roof, thank you).

The Caterham 620R features a gunmetal chassis held up by De Dion rear suspension and 13-inch alloys. Its nose cone is designed to optimise airflow, and there’s a race-developed cooling system. The driver faces a race-spec steering wheel and performance-focussed gauges amidst a sea of carbon fibre.

Certainly, it’s a far cry from the crossover SUV and subcompact car Caterham is planning!
