Read Autocar's exclusive interview with Caterham boss, Ansar Ali. This is the incredible new Caterham Superlight R500, the fastest-ever iteration of the standard Seven, with a power-to-weight ratio of 520bhp per tonne and capable of 0-60mph in just 2.9sec. It’s powered by Ford’s lightweight, all-alloy, 2.0-litre Duratec engine, which delivers 263bhp and 177lb ft of torque to the rear wheels via a track-biased, sequential-shift transmission. Along with more power, there’s new technology on this latest Superlight. It now comes with keyless start, a redesigned digital dash with shift lights, and optional launch control. It’s fitted with race-developed, super-sticky Avon CR500 tyres, optional Eibach springs and dampers, and a carbonfibre Induction airbox derived from the C400 race series. Despite all of these track-focused extras and more modern high-end switchgear, Caterham’s engineers have managed to cut around 9kg from the Seven’s already featherweight chassis by using more aluminium, carbonfibre and Kevlar in the build process.The new R500 also gets exterior styling tweaks taken from the flagship CSR model, including carbon winglets designed to improve downforce. The R500 has just gone on sale, with prices starting from £36,995.
