Whilst still being built around Colin Chapman's ethos of "add lightness", the R400 adds something else too... Horse power. Lots of horse power.

 As was Mr. Chapman's wish, all unnecessary comforts remain absent to save weight and reduce mass. What this means is that the R400 breaks the 400 bhp-per-ton barrier, something which many contemporary supercars struggle to achieve. The result is a car that delivers pure, unadulterated driving thrills.

The Superlight R400 is supplied as standard in component form for self assembly, complete to your chosen specification with all the parts you'll need to get your car on the road. It'll come with a first fill pack with all the necessary fluids required to complete your car, so all you'll need in addition to this are some basic tools, a little patience and a splash of fuel! Average build time for a novice is between 60 – 70 hours, with our team at Caterham already putting 20 hours of build work into the car before you receive it. Further more, our technical advice line and detailed build manual ensures the process is stress free and enjoyable. Building a Seven is a unique, exciting and rewarding experience, but if you don't have the time or space you also have the option to have your car factory built.

The Superlight R400 is available with both the standard chassis and the wide-bodied 'SV' chassis. The standard chassis offers the compact lightweight dimensions that have made the Seven a legend in its 50 year history.

The SV chassis gives increased interior and luggage space due to the greater width and length of the car, making it suited for extended touring or for customers over 6'2" in height. The SV also benefits from the additional stability offered by wide-track front suspension and increased range from a larger fuel tank, with only a 25kg weight penalty over the standard chassis.
