The Radical SR10 iRacing partnership is official. iRacing has formally announced that the Radical SR10, the turbocharged powerhouse of the British manufacturer’s fleet, will join the service for the 2022 Season 3 build. This next-generation sports racer is set to replace the legendary SR8 as the primary vehicle for official Radical competition, bringing a massive jump in torque and modern electronic systems to one of the most popular single-make series on the platform.
Turbocharged Performance: The EcoBoost Leap
The Radical SR10 iRacing model is built around a bespoke 2.3-liter RPE-Ford EcoBoost engine, a significant departure from the high-revving V8 units of previous generations. This turbocharged four-cylinder produces a staggering 425 horsepower and 380 lb-ft of torque. By utilizing a custom Garrett G-Series turbocharger, Radical has minimized lag and maximized mid-range punch, allowing the SR10 to accelerate from 0 to 60 MPH in just 2.4 seconds. This engine is integrated with a Hewland GT3-derived six-speed sequential gearbox, ensuring that every ounce of power is delivered to the rear wheels with surgical precision.
iRacing’s official announcement highlights the vehicle’s incredible power-to-weight ratio. Weighing only 725 kilograms, the Radical SR10 iRacing car delivers nearly 600 horsepower per tonne, rivaling the performance of top-tier LMP2 and GT3 programs. The simulation will feature high-fidelity audio recordings of the turbocharged engine and a meticulous recreation of the car’s aerodynamics, including its high-downforce composite bodywork and carbon-fiber bi-plane rear wing.
Advanced Electronics and Driver Aids
One of the standout features of the Radical SR10 iRacing car is its modernized cockpit. The vehicle features a Formula-style steering wheel with an integrated 4.3-inch TFT display, providing drivers with more real-time data than ever before. From engine strategy manettino switches to detailed tire pressure and temperature monitoring, the SR10 is a “technical” racer’s dream. Additionally, the car introduces an optional electronic power-assisted steering (EPAS) system and an automatic torque-biasing limited-slip differential, making it a more approachable yet equally rewarding machine compared to its raw predecessor.
The New Home of the Radical Cup
With the launch of the Radical SR10 iRacing car, the official “Radical Challenge” series is undergoing a transformation. The SR10 will become the exclusive car for this high-tier road racing series, which features standing starts and sprint-style competition on the world’s greatest circuits. While the beloved SR8 will move to the “Legacy” content tier and become free for all members, the SR10 will lead the charge as the premier choice for competitive sports racer competition. Whether you are looking to hone your skills for an LMP debut or simply want to experience the thrill of a 180 MPH open-cockpit rocket, the SR10 is ready to deliver.
Launch Details and Availability
The Radical SR10 iRacing machine will be available for purchase at the standard car price of $11.95. Its inclusion in the 2022 Season 3 build alongside iconic tracks like Fuji Speedway and Sandown International Raceway ensures a packed debut season. The car’s long-life powertrain—designed to run for 80 hours between rebuilds in the real world—is reflected in the sim through its reliable and consistent performance during long endurance stints. The era of turbocharged Radical racing has officially arrived; prepare to experience the torque.
