The Superlight R400 uses a two-litre Cosworth engine producing 210bhp and 150lb/ft of torque at 6300rpm.

It weighs just 525kg, resulting in a power-to-weight ratio of 400bhp per tonne and a 0-60mph time of just 3.8 seconds.

The car was the first Caterham model to benefit from new laser cutting and robot welding chassis technology and the result is a 12% increase in torsional rigidity.

Assessed by the RAC at the time, they concluded: “Mated to a new robot-jig welded chassis, the R400 provides the driver with even more confidence to plant this legendary sports car into corners.

The rigidity of the space-frame has increased by 12% and the greatly reduced flex provides improved grip, improved feedback to the driver and ultimately more speed on the track.

The torque characteristics of the R400 power plant provide instant performance and, more than ever before, there is an emphasis on ensuring all the messages from the road are faithfully transmitted to the driver through the suspensio...
