The New Radical SR10: Pure Extreme Performance

With a high horsepower, long-life powertrain, the new Radical SR10 is everything you’d expect from a Radical – turbocharged. Targeted at track-day enthusiasts, motorsport country club members, and racers across the globe, the SR10 delivers more power and torque than has ever before featured in Radical’s SR line-up, with a new engine and drivetrain package optimised for both performance and durability.

The new SR10 is designed to keep you on the track for longer, faster. Whether lapping casually at your local motorsport country club, or dicing with GT and LMP competition in an around-the-clock enduro, the SR10’s sole purpose is to out-run and out-manoeuvre the competition whilst remaining easy to drive and cost-effective to run.

Demand from Radical’s customers for a turbocharged variant of our legendary SR line of Sports Racers propelled the new model’s extensive test programme, which continued behind closed doors throughout the UK’s COVID-19 enforced lockdown. Given the SR platform’s longstanding reputation for providing electrifying performance through optimised aerodynamics and outstanding grip, the primary focus was on maximising both the new powertrain’s incredible performance as well as its durability, for easier operation and long service intervals.

The SR10 applies Radical Performance Engines (RPE) cutting-edge engine tuning capabilities with the proven durability of Ford’s EcoBoost engine architecture. This is no ordinary production unit; as Radical’s in-house powertrain division, RPE have developed a bespoke turbocharger, induction and engine management package to release over 425bhp and 380lb-ft of torque from the engine. A bespoke Garrett G-Series turbocharger delivers better throttle response and reduced lag, with forged pistons and connecting rods and a bespoke dry-sump lubrication system for bulletproof durability.

This high-output engine is integrated with a new Hewland GT3-derived six-speed gearbox. The SR10 is Radical’s first application of the Hewland TMT transaxle, originally developed for the FIA F2 single-seater.

This compact unit includes an integral paddleshift actuator and innovative WaveTrac ATB differential for maximum traction in all conditions, and is a perfect match for the high torque generated by the 2.3L High Output variant of the RPE-Ford inline four-cylinder engine.

As recently debuted on the SR3 XX, the driver’s environment features a new wheel-mounted LCD multi-page display and additional car controls at the driver’s fingertips. On the SR10 this includes multiple engine and gearbox mapping options and adjustable weighting for the optional electronic power steering system, also a first for the SR model line.

“With the SR10 we’ve truly achieved our objective of creating a car with the visceral performance of our SR8 but in a longer life, more durable package, packed with the latest Radical data and electronics capabilities,” said Joe Anwyll, CEO of Radical Sportscars. “We’ve brought together the best powertrain technology from RPE, Ford, and Hewland to create a package with over 425bhp and 380lb-ft of torque, making the car both incredibly responsive and easier to drive.

“The SR10 expands on the class-leading architecture of the SR model line and gives SR3 and SR8 owners alike a great next level of Radical performance – wherever they use the car.”

The new Radical SR10 is available to order now with the first deliveries scheduled from October 2020. Indeed, with Radical having teased the SR10 to some of its most loyal owners, several deposits have already been taken for the first cars out of Radical’s Peterborough, UK production facility. Closely following the launch of the latest SR3 XX iteration in May, production at Radical has bounced back quickly post-Coronavirus lockdown. An intensive calendar of factory and dealer-supported track and race events into 2021 ensure Radical owners can enjoy their new cars to the maximum.
