Click here to download printer friendly version The Radical SR8 has taken the racing and trackday scene by storm in 2005. Based on the SR3 chassis, the SR8 boasts an all-new bodywork and aerodynamic package which endows it with class-leading handling characteristics, whilst maintaining enough room for two large adults. All who are fortunate enough to drive the SR8 are amazed at how easy such a high-performance vehicle is to drive.

At the heart of the SR8 is the amazing 363bhp Powertec RPA V8 engine. This unique powerplant provides enormous power, delivered with a very flat torque curve. Revving to 10,500rpm, this 2.6 litre engine has been described by Circuit Driver magazine as "the most important development since the Cosworth DFV".

Combine the power of the Powertec V8, with an all-up weight of only 650kg, more downforce than the combined weight of the car and driver, huge leve;s of mechanical grip courtesy of purpose-designed Dunlop tyres, a paddle-operated, semi-automatic gearbox and you have a true Le Mans prototype experience at a fraction of the cost.

Radical are working with the Le Mans Series organisers and Dunlop to develop a World Radical Cup in which the SR8 is the true stepping stone from club racing to Le Mans.
