The car is absolutely nailed on - fantastic stability through the high-speed corners and tremendous acceleration. This thing feels like it can go on and on.

Ben Anderson, Autosport

After two days testing and racing this ‘torque monster’ at Sebring, the car performed flawlessly over eight 30-minute sessions. This  SR10 is a visceral dream to drive.

Jim Booth, multiple Radical owner and Radical Cup racer.
