At the heart of the SR3 SL beats the advanced Ford EcoBoost engine. Turbocharged and with 300 bhp, it has direct fuel injection and a fly-by-wire throttle, coupled to a six-speed paddleshift to allow for lightning-quick 80ms gear changes.
Protected by a lightweight spaceframe chassis that’s tested and approved to FIA sportscar racing standards, and an aluminium honeycomb crash structure developed at Cranfield’s Formula One testing facility, you’re driving the safest car of its type.
Fully-floating 280mm disc brakes at the front and rear provide stopping power beyond the abilities of any other supercar. Ferrari, Lamborghini and Porsche owners should watch their mirrors… no other road car comes close, or passes, on a track day.

The SR8 RX is based on the SR3, the SR8 is a more extreme version intended for track use but can be registered for the road. The SR8 also features the largest engine Radical has ever put in their cars, with the 2600 cc RPE RPA V8 constructed by combining elements of Suzuki inline-4s, and producing 363 hp (271 kW). A further variant, known as the SR8LM, increases the engine to 2800 cc and brings power output to 455 hp (339 kW). In August 2009 Michael Vergers, driving an SR8LM, set a new lap record (6 minutes, 48 seconds) for a road legal production car at theNürburgring Nordschleife circuit. The previous record (6 minutes, 55 seconds) was also set by Vergers, in 2005 at the wheel of a Radical SR8.
