Radical Sportscars, the company that made headlines back in 2009 after setting a Nürburgring lap time of just 6:48 in its street-legal SR8 LM, unveiled two new models over the weekend. One is a tweaked version of Radical’s mid-range SR3 and the other is a yet-to-be-built high-performance version of the brand’s already extreme SR8 flagship.

The new SR3 variant is called the SR3 RSX and it’s essentially a slightly faster take on the SR3, which has been in production now for almost 15 years. The car packs a 1.5-liter four-cylinder ‘RPE Generation 3’ engine and has 210 horsepower and 124 pound-feet of torque to play with. The Gen 3 version of the engine benefits from larger-bore exhaust, bigger throttle bodies and revised mapping.

The car also benefits from LED detailing and new front and rear diffusers, and it features for the first time a hardline braking system as standard as well as the latest-spec LCD display.

Radical says SR3 RSX owners can expect 0-60 mph acceleration in 3.1 seconds and a top speed of 155 mph.

The other model unveiled by Radical is the SR8 RSX. This model is said to have been influenced by Radical’s SR9 LMP2 prototype race car and features a new FIA-compliant tubular steel spaceframe chassis.

Its choice of powerplant is a 3.0-liter V-8 engine that delivers its peak power at a lofty 10,500 rpm. Peak power is 440 hp while peak torque comes in at 280 lb-ft. Radical is yet to release performance figures for the SR8 RSX but with a curb weight of about 1,900 lbs you can bet it will be quick. The transmission is a paddle-shifted seven-speed unit and variable-assistance power steering is also featured.

Radical plans to launch the SR8 RSX early next year.
