The Seven® 420 is the most potent naturally aspirated Seven® that we make.

Designed to provide a new high performance benchmark, the 2.0-litre Ford Duratec engine which powers Caterham’s premium range of Sevens® has been re-developed in conjunction with the Caterham Group’s engineering consultancy, Caterham Technology & Innovation (CTI). CTI’s extensive development work has resulted in an additional 65bhp over the cars predecessor delivering formidable, high-adrenalin performance. The new engine delivers its peak power at a lofty 8,500rpm,  and boasts an incredible 120ps-per-litre.

New to Caterham, the latest car includes a ‘Sport’ mode which, when selected, provides the car with even sharper driving characteristics, while enabling the vehicle to deliver its peak performance. Performance is bold – the sprint to 60mph takes just over three seconds, before propelling the Seven® 420 to a maximum speed of 140mph. The power is conveyed to the road via a six-speed gearbox and the new car sits on adjustable dampers with Eibach Springs.

The Seven® 420 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. Your engine and gearbox will be available as a seperate package.

All you'll need in addition to this are some basic tools, a little patience, some oil and a splash of gas! 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.

If you opt for a factory build, your Seven® will be shipped as a factory-built rolling chassis. The engine and gearbox are not included in the base price and are available as a separate package, which can then be fitted by a third party that will be recommended to you by your local dealer.

Available in left or right hand drive.

1. The Seven 420 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.
