2011 Radical SR3 RS

2011 Radical SR3 RS
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. 2011 Radical SR3 RS
It is the world's most successful sports-racer, with over 600 satisfied customers. The SR3 RS is a sure-footed, highly-developed racer, adept and rapid in the hands of both the novice trackday driver, and seasoned racing professional.

2011 Radical SR3 RS
The SR3 RS is powered by the Powertec four-cylinder range of engines, from 1340cc to 1500cc and beyond. It's a proven classwinner, not only in Radical's single-marque race series, but many other multi-marque championships around the world too.


2011 Radical SR3 RS
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. With an integral torque-biasing differential, this reliable, easy-to-maintain unit is one of the SR3 RS's strengths, offering strong traction out of corners. Swapping gear ratios to suit specific tracks is a straightforward job.

2011 Radical SR3 RS
Four-pot callipers, with vented discs on each corner, endear the SR3 RS with awesome stopping power.


The SR3 RS features Radical's FIA-specification crash box and central safety cell, whilst styling cues taken from the SR9 LMP2 car, including the high-nose front-end, offer not only dramatic styling, but also advanced aerodynamics, with a full-underfloor diffuser for leech-like grip. Dunlop tyres, developed exclusively for the SR series, complete the package.

An ergonomic and comfortable twin-seat cockpit makes the SR3 RS an ideal trackday car and endurance racer, with in-built engine datalogging, and an advanced LCD dash/multifunction display. Centre-locking wheels, and optional air jacks mean that, should the weather turn, the switch from slick to wet tyres is rapid and easy.
