Lower Costs, More Data, Crazy Fast
Easy to use and economical, the all-new Radical SR10 aims to keep riders on the track for longer periods of time at faster speeds, whether dicing on the local club’s track day or racing in the Radical Cup. Building on the architecture of the Radical Motorsports SR model line-up, which includes the SR3 and SR8, the SR10 delivers the next level of Radical performance, incorporating aspects of the brand’s larger RXC car lineup.
Made in Peterborough at the Radical Motorsports UK production facility, the rear-wheel-drive mid-engined SR10 is powered by a turbocharged 2.3-liter inline-four developing 425 horsepower and 380 lb-ft of torque. Developed by the Radical Performance engines of the Ford EcoBoost engine, the SR10’s four-pot features a Garrett G-Series turbocharger and a dry-sump lubrication system. Radical claims that the internal turbocharger offers reduced lag and better throttle response.
Another novelty is a Hewland GT3 six-speed gearbox mated to a Hewland TMT transaxle. The SR10 is the first Radical to use the TMT transaxle, which was first developed for the 2009 FIA F2 race car. Built on a lightweight Spaceframe chassis to FIA specifications, the SR10’s priorities are centered on maximum durability and performance. A fully adjustable Nik-link suspension system, interchangeable anti-roll bars, Intrax triple-tuned shocks with anti-roll control technology and center-locking forged hubs provide chassis control. A paddle-activated shift system with automatic throttle flashing and a torque-sensing limited-slip differential complete the performance kit. Radical estimates the engine rebuild interval at 80 hours of use, or over 6,200 miles of action at race pace.
The two-seater open cockpit features an ergonomic (waterproof) instrument panel, AiM Formula steering wheel, lightweight shift paddles, a steering wheel-mounted multi-page LCD display with plenty of real-time data (as on the SR3 XX ) and an adjustment of the brake polarization on the instrument panel. In another first for the SR model line-up, the controls on the Radical SR10 include adjustable steering assistance for the optional electric power steering system, as well as engine and transmission mapping options. Other optional features and enhancements include a carbon composite high-pressure dive aircraft package, a mid-position single-seat layout and a pneumatic cylinder system.
Aimed at endurance racers, track day enthusiasts and motorsport country club members, the Track-Only Radical SR10 promises electrifying performance, exceptional grip and true aerodynamics. Ready to order now and selling worldwide for £ 105,000 (around $ 137,000 at current prices) excluding delivery charges, the first SR10s are expected to reach customers in October.
