Caterham Seven 420R Race Car

Available from Williams Caterham

The Seven Championship UK is the pinnacle of Caterham Seven Motorsport and Britain’s only nationally recognised Seven race series. It’s the top end of the Caterham Championship and is the only Caterham series to race on race slick tyres with the option of full Avon wets also. The speed of this car is similar to a GT-4 race car and with the handling to match make it one of the greatest one make race series in the UK.

“What exactly does that mean” we hear you ask…. To put it simply, this is the racing series to find the Official British Caterham Champion. No other Seven-based racing series is recognised in this capacity – plus, like all of our Championships, it’s fully run by the manufacturer.

Caterham has a well-established history when it comes to racing, we’ve been at it since day one – so naturally it’s one of the most competitive and exciting competitions going. To keep the playing field level, every car on the grid is identical, and the car is question is specifically designed for the competition.

A 180bhp 2.0 Caterham Motorsport Tuned Engine, paired to a six-speed sequential gearbox, is nestled within the bespoke racing chassis. One seat, no lights, this thing means business. Unlike other national racing series, this is pretty much out-of-the-box competition, meaning the season is included with the cost of the car, and there is no need for expensive testing and set ups. It’s all down to the skill of the driver.
