From the people that gave us the SR2 and the SRZero comes a new track-day and road-focused roadster that’s expected to be the company’s flagship model of 2011. Radical Motorsports recently introduced their new bad boy, the SR3 SL, at the Autosport International Show in Birmingham, England.

According to Radical Motorsports->ke3734, the SR3 SL is expected to be their most advanced supercar yet. Certainly, there's a lot to like about this British beast. It's got 300 horsepower inside of it, making for a scintillating open-top joy ride. It's lightweight structure - overall weight is just 675 kg - allows it to to quick and agile, even for Radical's standards.

And if you just happen to have an insatiable lust for power and speed, Radical Motorsports is offering a Race Pack for the SR3 SL that comes with added features, including an engine calibration map selection that provides ‘road’, ‘wet’, and ‘racetrack’ suitable maps, a racing bi-plane rear wing, racing tire options, and an FIA-approved fuel cell.

Suffice to say, Radical took the time to load up on the SR3 SL, much to our approval.

UPDATE 09/15/11:The Radical SR3 SL has been around for some time now, but it was only this week when it made its public debut at the Frankfurt Motor Show. Suffice to say, the car looks hella nice up close and personal, too. Check out the new images in the gallery provided!

Details on the Radical SR3 SL after the jump.

Exterior and Interior

Styled and built to look like a true-to-its-roots racer despite being a street-legal vehicle, the SR3 SL weighs in at just 675kg – and that comes with full body aerodynamics, including the same core chassis and a compliant suspension. The new Radical sports car also has an F1-style paddle-shift gear change with an auto blipper, a fly-by-wire throttle, and a set of street-ready wheels and tires.

Performance

Like any modern-day track racer, the Radical SR3 SL has loads of power hiding underneath that racer exterior. It’s powered by a 2.0-liter Ford EcoBoost four-cylinder engine that produces 247 horsepower with an additional 53 ponies tacked to it courtesy of Life Racing, rounding up the total output of the SR3 SL to 300 horsepower and 340 lb/ft of torque. The SR3 SL hits a 0-60 mph time of just three seconds with a top speed of 165 mph. The newest Radical to come out of the block also has a brand-new turbocharged unit with Twin-Independent Variable Cam Timing and state-of-the-art, high-pressure Direct Injection, transmitting power through a six-speed sequential gearbox.

Radical is also offering a Race Pack for the SR3 SL that comes with added features, including an engine calibration map selection that provides ‘road’, ‘wet’, and ‘racetrack’ suitable maps, a racing bi-plane rear wing, racing tire options, and an FIA-approved fuel cell.

Then there’s the matter of the European Small Series Type Approval, which the SR2 SL was given, making a registered racer in a lot of European countries.

Pricing

The Radical SR3 SL has been given a price tag of £67,750, or about $107,000 based on current exchange rates. It’s not cheap by any account, but the price of owning one of these vehicles should justify the exorbitant price tag attached to it.

Competition

The Autosport International Show witnessed the unveiling of another vehicle that could give the Radical SR3 SL a serious run for its money.

That vehicle is the Caterham SP/300.R, which comes with a 2.0-liter Ford Duratec Supercharged engine that delivers 301 horsepower at 7,500 RPM with a maximum torque of 290 Nm at 7,500 RPM and a Lola Formula 3 derived gearbox mounted rear suspension system. According to Caterham, the SP/300.R can run north-to-60 in just 2.8 seconds with a top speed of 180mph.

Compare that to the numbers posted by the SR3 SL and you've got two racers that should end up staring each other down in the near future.
