Any Radical in the USA is fantastic to experience up close, especially in its native environment: the racetrack.
The Radical SR3 SL here is the only two-seat model in the United States – so it is:
a) the quickest car around almost any racetrack — including the Nurburgring, where Radical has long held an unbeat-ably quick pace in the 6.44-second SR8. The SR3 SL is no slouch either: its roughly 7:00-second Nordeshleiffe lap is still in the top 20 for any kind of car, racers included.
b) one of the only street-legal track cars of this caliber of performance
c) a two-seater!
Amazing stuff. 45 original, super-high-res photos of this SR3 SL at Atlanta Motorsports Park. Plus 30 or so photos of the latest official Radical SR3 SL photos.

TECHNOLOGY & SPECIFICATION
The SR3 SL flatters on all levels: performance, handling, styling and specification.
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.

BREATHTAKING PERFORMANCE AND EASY TO DRIVE
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, with over 900 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 such as the Radical SR3 Challenge, 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 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.
Four-pot callipers, with vented discs on each corner, endear the SR3 RS with awesome stopping power.
