As proven by Radical’s own best-selling SR3 race car, our stroked 1500 proves you don’t need capacity to deliver outstanding performance. Loved by circuit and off-road racers alike, this RPE-developed variant benefits from bespoke components including a forged Arrow crank and unique Cosworth pistons.

Core to the Radical DNA is the aerodynamic grip, nimbleness and balance. Known all around the world, by drivers of all abilities as a terrific car to drive – easy to pick up but hard to master.

Unlike road cars that have been modified for track use, the full Radical range has been designed for track use from factory. The chassis is optimized for performance, focusing on aerodynamics, high downforce, and stability at high speeds. This ensures that the car provides maximum grip and agility during high-performance driving.

Beneath the skin of every Radical is a tubular spaceframe chassis that provides an excellent strength-to-weight ratio, enhancing the car's overall performance and safety. The design of the chassis helps reduce the overall mass of the vehicle, resulting in improved acceleration, braking, and cornering performance. Surrounding the chassis, the lightweight composite fiberglass bodywork is available in a choice of seven colors from factory. Combined with the spaceframe chassis, this provides unbeatable value for money for a pure track car that is easy to maintain and repair anywhere in the world.

Adjustable rear push rods and three-way dampers allow drivers a full range of control to setup the car ready for the track ahead. An adjustable rear wing allows the driver to change the setup to suit the conditions, exploring the balance between straight-line speed and cornering performance.

With over 25 years of experience and almost 3,000 cars sold to date, every component on a Radical has been tested under extreme conditions to give customers the confidence they need to push lap after lap. New innovations, such as the optional cockpit safety structure, are designed to further protect the driver. FIA specification crash boxes and fuel cells along with full electronic fire extinguisher systems come as standard.

Choose from single or dual seat options to allow for driver coaching or entertaining passengers. Each car is also available with various seating position options including centre-seat, left or right-hand drive. The dashboard features a customizable digital display to bring real-time information to the driver, and comes equipped with an onboard video system with GPS and race logging, including brake pressure and steering sensors.
