Targeted at “track day enthusiasts, motorsport club members and racers from across the globe,” the all-new Radical SR10 is the latest in a long lineage of lightweight British track racers. Manufactured in Peterborough at the Radical Sportscars United Kingdom production facility, it aims to keep the drivers on the track for longer stretches at faster speeds, 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-maneuver the competition whilst remaining easy to drive and cost-effective to run,” the manufacturer explains.
Inside the body is a 2.3-liter Ford EcoBoost engine with custom Garrett turbos, along with new induction and engine management systems. Equipped with a powerful racing exhaust, the tiny Radical SR10 now produces 430 hp and 380lb-ft (515 Nm) of torque – that’s more powerful than the SR1, SR3, and SR8 – and sends it to the rear wheels via a new Hewland six-speed paddle-shift auto-blip gearbox and a torque-biased limited-slip differential.
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.
Built on a lightweight spaceframe chassis to FIA specifications, the SR10 has a body with great downforce, LED headlights, a two-plane rear wing, fully adjustable suspension, and triple adjustable shock absorbers, as well as massive front and rear brakes. 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 engines and gearbox mapping options and adjustable weighting for the optional electronic power steering system, also a first for the SR model line.
Overall, Radical estimates the SR10 weighs 725kg, is capable of delivering 2.3g, and offers a power-to-weight ratio of 595hp per ton.
The new Radical S10 with Ford engine is a great choice for on-track entertainment. The SR10 is already available to order for £105,000 (about $137,000), excluding delivery fees, the first SR10s should reach customers in October.
