What is it?
Remember how last year’s 620R was essentially a road-going version of Caterham’s R600 race car? Well, the 620S is, essentially, the same car, retaining as it does the febrile 310bhp supercharged four-pot, but it now takes the road-going part a bit more seriously.
Hence the R’s uncompromising sequential gearbox has been swapped out for a standard five-speed manual, the suspension components have been taken down a notch (from 'race' level to 'sport') and you get a windscreen. Plus the hood and doors to go with it.
The alterations, not to mention a £5k reduction in starting price, are likely to play well to prospective 620 buyers. Caterham readily concedes that despite the model’s overt relationship with the track, not all its customers are interested in the lap record at Brands. Many simply want the supercar-troubling performance twinned with a Seven’s normal amenability.
'Normal' though, in the 620‘s case, is to be taken advisedly. While the springs and dampers may have changed, you still get the ‘wide track’ front geometry and uprated brakes, plus an adjustable anti-roll bar and limited-slip differential at the back to go with the bespoke rear-exit exhaust system.
Even with the extra weight of bigger, 15in wheels, more kit and the now optional SV chassis, the 620S, at 508bhp per tonne, remains a decidedly senior option.
