The 152bhp Seven 310 is priced from £24,995 fully-built (£21,995 if you want the pleasure of building it yourself). It has been subjected to various tweaks, including upgraded camshafts and engine remapping. Owners of the 270 on which the 310 is based can upgrade to the 310 for just £1495.
The tweaks came about through Caterham's motorsport programme, although the extra 17bhp was a surprise discovery. Caterham expects demand to be strong, so it has launched the 310 as a full variant on the Seven formula, rather than simply as an option on the 270 range.
A six-speed gearbox is a £2500 option, and LED headlights – a first for Caterham on the 310 - will also be rolled out across the Caterham range as an £800 extra. Caterham's R Pack, which makes the car more track-focused, is a £3995 option.
The performance upgrades take the 310 to 62mph from a standstill in 4.8sec, and onwards to a top speed of 126mph. Caterham claims the 310 is the most balanced Seven since the Superlight R300 model.
Caterham’s chief motorsport and technical officer, Simon Lambert said: “If Caterham was only going to make one car for the rest of its days, this would be it. It’s entirely fitting that the Seven 310, which we feel perfectly synchronises power and handling, has come out of the motorsport engineering process.”
Caterham has sold 305 cars across 2016 so far, and is expected to hit 550 before the year's end. This is in stark comparison to Lotus, which has sold 141 cars in 2016 so far, and only one car in July 2016. The 310 is available to order immediately.
