If you're looking for a bare-bones, no nonsense roadster, the upcoming Autosport International motorsport show in Birmigham, England, is the place to be. That's where Caterham is set to unveil an all-new vehicle, and where Radical is also planning to debut its latest street-legal race car.

Now, that term is used to describe many performance automobiles, but if anyone can lay claim to it, it's Radical. The company makes Le Mans Prototype-style cars that are nominally street legal, but every bit the purebred racers they look like. The SR8 holds the lap record at the Nürburgring, and is soon to be joined in the Radical lineup by the SR3 SL. Fully street legal, the SR3 SL is aimed at track-day enthusiasts looking for a car they can drive to the circuit, lap to their heart's content and then drive back home... just like in the good old days.

The SR3 SL is powered by a 300-horsepower version of the Ford EcoBoost five found in the Focus ST, optimized in-house by Radical. It's mated to a six-speed paddle-shift sequential gearbox that automatically blips the throttle on the downshift, and with a curb weight under 1,500 lbs, is sure to be a serious thrill ride.

Radical Enters New Era With SR3 SL
16th December 2010

Radical Sportscars today announces the SR3 SL, a new trackday and road-focused roadster that spearheads Radical's 2011 product line-up. The SR3 SL will be formally unveiled at the Autosport International Show on 13 January 2011, held at the NEC, Birmingham.

Optimised for the growing trackday and corporate/race school market, the SR3 SL is Radical's most advanced sportscar ever, powered by a 2,000cc Ford-RPE (Radical Performance Engines) EcoBoost engine developing 300bhp as standard.

Whilst Euro5 emissions compliant, this brand-new turbocharged unit with Twin-Independent Variable Cam Timing and state-of-the-art, high-pressure Direct Injection transmits its power to the road via a six-speed sequential gearbox. With European Small Series Type Approval, the SR3 SL can be road registered in any EU country, and many more.

Available on the road with a Formula One-style paddleshift gearchange with auto-blipper, fly-by-wire throttle and advanced engine management system, it's the closest experience to a Le Mans car for the road. At only 675kg, and with full underbody aerodynamics, there's little that can touch a Radical for performance. For those that want to take the SR3 SL experience even further, Radical will offer a Race Pack, featuring options including an engine calibration map selection (giving 'road, 'wet' and 'racetrack' suitable maps), FIA-approved fuel cell, racing bi-plane rear wing and racing tyre options.

Radical will be revealing the SR3 SL on Thursday 13 January at Autosport International, alongside the 2011-model SR3 RS, and the new SR8 RX, featuring RPE's new 2.7 RPX V8 engine. Media are invited to come and view the 2011 product range, meet the Radical management team, and browse the Radical stand with refreshments.

      I sure hope radical comes to the usa.
        • 4 Years Ago
        They already are here. Well at least they have an American spec series that travels alongside the Viper Cup.
        • 4 Years Ago
        I am sure there are 100 U.S. safety standard it doesn't pass :( I hate regulations!!!! I really don't purchase based on wreck capabilities, DO YOU?

        Yeah they're here, I see them all the time at the track but they aren't street legal unless you manage to register them as a kit car. At least in California.

      sorry......the 'ring lap record was set by a german in a porsche.......something like 6:12 .. and it was done in the early 80's when the track was much more dangerous
        • 4 Years Ago
        Stefan Bellof's 6:11 lap time doesn't count as it was a race car. We are talking about street legal cars. His record is likely not to be broken for a long time if even simply because of the current state of racing at the ring. You would need a street car or a GT3 car that is faster than a group C car. Don't hold your breath.

        we're talking street legal here buddy.
      • 4 Years Ago
      Thats not a Ford Ecoboost five. Its a Volvo Turbo Five.
        • 4 Years Ago
        What Zmatt wrote.
        • 4 Years Ago
        It's a Radical-tuned Ford EcoBoost 2.0L.
        • 4 Years Ago
        Actually it's a duratec ST, that's the name of the I5 turbo used in the ST. It's a Volvo/Ford design.
        • 4 Years Ago
        Or even a Ford ecoboost 4

      I have seen Radical's at the Spring Mountain Race Track in Pahrump, NV. http://www.springmountainmotorsports.com/radical-division/radical-cars/ They have done some pretty wild things with Busa motorcycle engines in those light cars. In fact the owner made a car with 2-Busa engines and the car is pushing almost 500 HP and weights just under 1000 pounds. Power to weight is off the chart.
        • 4 Years Ago
        Radical themselves made it's V8 version. Also, it's not 2 Hayabusa engines. It's a V8 built with Hayabusa heads. There's a 2.8L and 3.0L option for the engine package. They're made by an American engine builder called Hartley Enterprises. The Ariel Atom 500, Caterham 7 Levante, and the Radical SR8 are powered by the same 3.0L Hartley V8.
