Video: Radical reveals road-going SR3 SL at Autosport International

It might look like an exile from the Le Mans paddock, but believe it or not this is the road-legal Radical SR3 SL. The 300bhp, 2.0-litre Ford engine means it has the power to match it racecar looks.

Considering the performance, the fact that this engine meets Euro5 emissions regulations is impressive. It's also fitted with twin-independent Variable Cam Timing and state-of-the-art, high pressure Direct Injection.

We take a closer look at this extreme British rival to the evergreen Caterham Seven.
