The term "racecar for the road" gets thrown around a lot, but if there's any company whose products are deserving of the title, it's Radical. The British firm makes LMP-style track cars that can (technically) be driven on public streets, as long as your chiropractor approves. With many Le Mans Prototypes switching from open cockpits to closed, Radical is doing the same with the new RXC. With a 3.7-liter Ford V6 producing 380 hp and 320 lb-ft of torque, and a spritely 900kg curb weight, the Radical RXC promises a 0-62 time of just 2.8 seconds.

The aerodynamically-optimized bodywork - complete with functional diffuser, full-width rear wing and front splitter - is also capable at its 175mph top speed of producing as much downforce as the car weighs, putting it into that rare and completely theoretical league of supercars that could (again, in theory) drive upside down in a tunnel. The composite body panels are draped over a high-tensile steel spaceframe chassis. Brakes are 330 mm at the front 310 at the rear (with optional carbon-ceramic discs) packed inside 17-inch wheels. Power is transmitted to the rear set through a seven-speed sequential gearbox.

Radical will be displaying both the race version at the Autosport International Show - the leading exposition of racing machinery - on January 10 in Birmingham, England. The roadgoing version is being put through the same European regulatory process as the SR3 SL roadster, and once it's approved, it will revive the classic formula of driving your car to the track, swinging it around lap after lap and then driving it back home.
