Radical SR3 Turbo

www.supercars.net
The new record was made all the more impressive by the fact that the all-new 1500 turbo-engined car had only covered a small number of development miles at Lotus' Hethel test circuit, and the record was achieved during it's first and only flying lap of the awesome 14-mile German circuit.
Radical's latest incarnation of their all-conquering SR3 extreme road / trackday car boasts a Powertec 1500cc Turbo engine, developed in-house, which boasts 320bhp, and 213 ft/lbs of torque at only 0.8 bar of boost.

First launched in 2002, the SR3 RS incorporates a six-speed sequential transmission, and drives via the Power Drive gear drive system, developed in partnership with Quaife especially for the SR3.
A true ‘world’ supercar, the SR3 RS is as much at home flat-out through Eau Rouge, as it is providing passenger rides for your friends around the Nordschleife.
