Radical SR3 XXR for Sale

The World's Best-Selling Race Car

Launched with more power and precision, the latest edition of the world's most popular race car improves on the legendary SR3 formula to enable drivers to lap faster, harder and for longer.

The SR3 XXR is the first Radical model to be fitted with Radical Performance Engines' Generation 5, biofuel-ready, 232 bhp engine as well as brakes from new technical partner, AP Racing.

Styling upgrades for the new SR3 XXR include revised LED lighting, LMP-inspired central tail 'shark fin' and new lightweight wheels. A carbon fibre splitter and rear diffuser will be offered as an option.

The SR3 XXR continues to offer AiM’s solid-state technology including a suite of data options and technology to help Radical drivers be the fastest on the race track. It also retains AiM’s popular Formula steering wheel technology, akin to those usually seen in high-level single-seater racing cars and Le Mans Prototypes.
