A fly-by-wire throttle ensures immediate power and response and the car will meet full Euro 5 emissions compliance for markets across the world. Despite their racing specification the engine and gearbox service intervals are up to 10,000km.

For territories and championships that allow it, Radical can also offer a 3.0-litre 480bhp variant of its RP-series V8 engine. In production since 2006, the RP V8 is a proven high-performance powerplant used by Radical's SR8 RX racecar and many other racecars worldwide. This latest 3.0-litre configuration takes the Radical concept to the absolute, while still offering affordable running and rebuild costs well below any other bespoke racing engine.

Both engine options drive the rear wheels through an all-new bespoke RPE/Quaife seven-speed transverse gearbox that is low in weight and ensures the overall weight balance remains very close to that of an SR3. Featuring paddleshift and an integral Quaife Automatic Torque Biasing differential, gear ratios are quickly and easily changed from the side of the gearbox like current F1 design practice. The in-house developed paddleshift system allows full-bore, 50ms seamless upshifts and automatically blips the throttle for clutchless downshifts without the need to heel-and-toe.

For the first time on a Radical the RXC features a bespoke Intrax Racing Suspension inboard push rod suspension system with double wishbones all round to reduce unsprung mass and further improve Radical's class-leading ride quality and handling. Four-way adjustment is available as an option on the RXC-optimised dampers, with all cars benefitting from GT3-style camber and suspension geometry adjustment.

330mm front and 310mm rear fully-floating disc brakes with six-pot calipers take care of braking. Carbon ceramic discs and calipers are available as an option. The brakes sit inside 17" centre-lock wheels front and rear - the biggest ever fitted to a Radical production car.

The AiM MXL2 LCD multifunction dashboard debuts on the RXC and provides a comprehensive snapshot of both engine information and performance figures. The optional datalogging system adds a comprehensive portfolio of configurable inputs, from brake pressure and temperature logging to G forces and suspension travel. AiM's acclaimed SmartyCam system can also be added to the system to provide video with a realtime overlay of data, ideal for lap time improvement or corporate use.

Not only is the RXC Radical's most technically advanced car but it is also its most comprehensively specified. The interior of the RXC features a multi-function fully adjustable steering wheel, EPAS power steering, electrically adjustable and heated wing mirrors, air conditioning, heated windscreen with single wiper and an adjustable pedal box. Occupants sit in bespoke Corbeau FIA-compliant trimmed bucket seats with six-point racing harnesses.
