Caterham has unveiled the most extreme road-going model it has ever produced.
The new Seven 620R will replace Caterham's current range-topping Superlight R500, and the company says it'll "set a new benchmark in outrageous performance".
It'll be powered by a supercharged version of Ford's 2.0-litre four-cylinder Duratec engine, which will produce a whopping 310bhp – enough for a kidney-pulverising 0-60mph time of less than 2.8 seconds and a top speed of 155mph.
The weight of the new car, which will make its debut at this weekend's Goodwood Festival of Speed, hasn't been released yet. But a source at Caterham told us we can expect it to tip the scales at somewhere around the 506kg of the outgoing Superlight, if not fractionally more thanks to the addition of the supercharger and intercooler.
That should give the Seven 620R an astonishing power-to-weight ratio approaching 600bhp/tonne.
Under the skin, a unique gunmetal chassis, a race-developed cooling package, De Dion rear suspension and high-performance dampers ensure a driving experience like no other. An air-flow optimised nose cone will also feature.
"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."
Such extreme performance doesn't come cheap, though – the Seven 620R will set you back a not-inconsiderable £49,995.
Orders are being taken now, with first deliveries expected later on this year.
