| Tweet | ||
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. It is the world's most successful sports-racer, wîth 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.
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.
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 wîth 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.
Four-pot callipers, wîth vented discs on each corner, endear the SR3 RS wîth 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, wîth 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, wîth 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.

 | While Formula One will be forever considered the pinnacle of motorsport, from a period between 1966 and 1986 there existed a series that would likely be the closest to 'anything goes' as any motor racing series could truly get. Based upon the FIA Group 7 cars but allowed to showcase unlimited engine sizes and unfettered aerodynamics, the Can-Am cars would have to be considered the pinnacle of motorsport technology and power of their era. And for more than a couple of years there would be one tea...[Read more...] |

Although the gentleman on the bicycle would drop out rather early due to leg cramps constantly going up and down on the mountainous roads, the battle between the de Dion motor tricycle and the horse would be an intriguing one. In the end, the same principles that played out in that first race would come into play many years later when the island hosted the 1961 Targa F...[Read more...] |
