2011–2014 Radical SR3 SL Specs & Performance

The Radical SR3 SL is a road-legal, track-focused sports roadster that brings the lightweight engineering of a racing machine to a car designed for public roads. Its low, open body, mid-engine layout, and rear-wheel-drive configuration prioritize balance and driver involvement over everyday comfort. With a curb weight of just 1,753 pounds, the SR3 SL combines a compact footprint with serious performance, giving it the character of a purpose-built sports prototype rather than a conventional roadster. The result is an unusually focused driving experience for enthusiasts who value rapid acceleration, responsive handling, and a direct connection to the road.

For the 2011–2014 model range, the SR3 SL uses a turbocharged 2.0-liter inline-four producing 300 hp and 265 lb-ft of torque. Power reaches the rear wheels through a six-speed manual transmission, while double-wishbone suspension and ventilated disc brakes at both ends support its performance-focused setup. AutoSpecsHub lists a 0–60 mph time of 3.3 seconds and a top speed of 161 mph. Its two-seat layout, 93.5-inch wheelbase, and 14.3-gallon fuel tank round out a machine engineered around speed and agility rather than passenger space or conventional practicality.
