What is it?
The Caterham Seven Roadsport 175 is the latest and most powerful variant of Caterham’s Roadsport range. Unlike the 125 and 150 versions, which use a 1.6-litre Ford Sigma engine, the 175 uses a 2.0-litre Duratec engine producing, you guessed it, 175bhp.
That’s exactly the same engine and state of tune found in the recently introduced Caterham Seven Superlight R300. So are we looking at the same car by a different name? While to an extent all Sevens deliver the same thrill-a-minute experience, in the nuances of how they go about it there is a fair difference between a Superlight Caterham and a Roadsport.
First up, Caterham Seven Roadsports run less sophisticated suspension, with a narrower front track and less adjustability (the platforms and dampers aren’t variable). Secondly, Roadsports get a five-speed gearbox in place of the six close ratios on Superlights. Thirdly, a Roadsport gets a heater and windscreen as standard, items you have to pay extra for on a Superlight.
To confuse matters, this particular Caterham Seven Roadsport 175 has the wider SV chassis (for those who want a little extra room), which incorporates the wider front suspension of the Superlight, but without the trick dampers.
