Overview

Pure extreme performance

Ideal for 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 high horsepower, long-life powertrain, the Radical SR10 is everything you’d expect from a Radical – turbocharged.

The SR10’s sole purpose is to out-run and out-manoeuvre the competition whilst remaining easy to drive and cost-effective to run. Radical Performance Engines (RPE) cutting-edge engine tuning capabilities and Ford’s EcoBoost's reliable engine architecture come together to unleash a powerful race engine with 425bhp and 380lb-ft of torque. 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
