The firm says its new flagship model has been designed to offer “a raw, exhilarating driving experience” on road and track, with a focus on weight-saving and aerodynamic efficiency.
Powering the Rapture is Ford’s 2.3-litre Ecoboost, as available in the Mustang and new Focus ST - which has been tuned by Radical to produce 350bhp and 320lb ft. Modifications include a lightweight crankshaft, forged pistons and conrods, and the addition of a twin-scroll supercharger from the Ford Focus RS.
The Rapture will sprint from 0-60mph in a claimed 3.0sec, and on to a top speed of 165mph.
Power is sent from the mid-mounted engine to the rear wheels through a six-speed paddle-shift gearbox, with an ‘auto blipper’ that automatically matches engine revs to road speed.
With a lightweight spaceframe chassis, the open-cockpit two-seater weighs in at just 765kg, giving a power-to-weight ratio of 458bhp per tonne – around the same as its Dallara Stradale and Lotus 3-Eleven rivals.
The Rapture features the same fully-adjustable suspension, braking and drivetrain systems as the SR3 and SR8 racers, which Radical says are easily accessible and repairable due to the Rapture’s modular body construction.
