Irrespective of which model you choose the unmistakable howl of a high-revving Radical engine on full throttle will prickle the hairs on the back of your neck. The source of that wonderful noise is our unique range of high-performance engines, assembled and built in-house since 1997.
We have developed our four-cylinder superbike powerplants to give drivers the experience of their lives – all of which give extreme, reliable power. These remarkable lightweight units have to withstand far greater cornering forces than they would on the road, so a dry sump and scavenge system has been developed which enables the motor to endure loadings as high as 3G.
The latest development of the RPV8 series is the most powerful, compact lightweight V8 on the market, and has been extensively developed for maximum reliability in extreme racing conditions. Over 300 RP units have been built to date, all benefiting from an F1 style crankcase design as well as MotoGP cylinder head technology. The engine also features four integral oil scavenge pumps, and it produces unrivalled levels of performance and reliability.
Any car in the range may be specified with the extraordinary PS1 electro-pneumatic paddleshift system, which enables incredible seamless gear shifts up and down the gearbox at the flick of a paddle. The combined autoblipper allows the driver to flat-shift on the way up through the gears, and downshift without using the clutch.
