What is it?
This is the Caterham Seven Superlight R300, the latest addition to the brutally quick yet feather-light Superlight series.
We’ve seen a Caterham Seven Superlight R300, but that was the old version with the 1.8-litre K-series Rover engine. This new Superlight R300 now uses the effortlessly torquey - and no doubt far more dependable - 2.0-litre Ford Duratec motor also found in the 263bhp R500 and the 210bhp R400.
In the Caterham Seven Superlight R300, the 2.0-litre Ford motor is detuned to produce 175bhp, so the R300’s acceleration isn’t quite as savage as in the R500. The R500 hits 60mph in a frankly terrifying 2.9sec, but the R300’s 0-60mph time of 4.5sec is still more than brisk enough - especially in a car where a windscreen is an optional extra.
But while the Caterham Seven R300 doesn’t get the extreme performance of its bigger brother (or the R500’s optional sequential gearbox), it still gets the same beefed-up front suspension and sticky, track-oriented Avon CR500 tyres.
