For motorsport enthusiasts, track-day aficionados, and racing enthusiasts worldwide, Radical Racing Cars has unveiled the latest addition to their lineup, the SR10. This high-performance vehicle promises to deliver more power and torque than any other model in Radical’s SR series. With its remarkable horsepower, long-lasting powertrain, and a touch of turbocharging, the Radical SR10 is designed to thrill.
The SR10 is purpose-built to dominate the competition while maintaining ease of use and cost-effectiveness. It achieves this through a collaboration between Radical Performance Engines (RPE) and Ford’s EcoBoost engine technology, resulting in a formidable 425bhp race engine with 380lb-ft of torque. This powerplant features a specially crafted Garrett G-Series turbocharger, enhancing throttle response and reducing lag. To ensure durability, the engine is equipped with forged pistons, connecting rods, and a bespoke dry-sump lubrication system. The high-performance engine is seamlessly integrated with a new Hewland GT3-derived six-speed gearbox.
The SR10 boasts a lightweight spaceframe chassis with an FIA-specification safety cell and crash structure. Its LMP-inspired, high-downforce composite bodywork, combined with latest-generation LED race lighting (including an FIA high-intensity central rain light), gives the car a distinctive and aerodynamic appearance. Additional aerodynamic enhancements come in the form of a bi-plane high-downforce track day rear wing and diffuser, XX-generation Le Mans pre-preg carbon composite mirrors, and latest-generation rear wing endplates.
Under the hood, the RPE-Ford 2261cc engine roars to life, delivering 425bhp and 380ft-lb of torque, thanks to turbocharging, direct injection, twin-independent variable cam timing, and drive-by-wire throttle. A custom Garrett turbocharger enhances performance. The engine’s internals include forged motorsport pistons, connecting rods, and a bespoke dry-sump system. Keeping it all in check is the latest Life Racing ECU with a detailed interrogation function for maintenance and analysis. The SR10 is also equipped with a high-flow racing exhaust system to ensure optimum performance.
Inside the SR10’s two-seater chassis, you’ll find a driver-focused environment optimized for a molded race seat insert. The AiM Formula Wheel with an integral LCD display, lightweight shift paddles, and on-wheel switching offers a modern and intuitive driving experience. Display functions include an LCD rev counter, gear indicator, shift light, and engine/gearbox strategy manettino controls. The ergonomic dashboard features a waterproof, backlit momentary touchpad and a dash-mounted brake bias adjuster. For added comfort, a wind deflector keeps the wind at bay.
The SR10 is equipped with powerful braking components, including Radical four-pot calipers on 315mm x 35mm front and rear fully-floating 48-vane disc brakes. Front and rear brake cooling systems ensure optimal brake performance. A solid-state Power Distribution Module (PDM) with Controller Area Network (CAN) linked wiring and telemetry enhances the car’s data integration capabilities, allowing additional data logging such as tire pressure and temperature monitoring and laser ride height logging. Safety is paramount, with an FIA specification foam-filled 77L fuel cell and a full electronic fire extinguisher system.
The SR10 is fitted with a six-speed Hewland sequential transaxle, and Radical has developed a paddle-activated gearshift system with an auto-blipper for smooth gear changes. The automatic torque-biasing limited slip differential ensures optimal traction. With its mid-engined, rear-wheel-drive configuration, the SR10 promises a thrilling driving experience.
The SR10 features a fully adjustable Nik-link suspension system with front and rear unequal length top and bottom wishbones, fabricated uprights, and front and rear adjustable pushrods. Lightweight cast aluminum updated uprights provide increased durability. The car’s interchangeable roll bars and Intrax triple-adjustable dampers with Anti-Roll Control (ARC) technology offer precise control and handling on the track.
In conclusion, the Radical Racing Cars SR10 is a track-focused marvel that combines power, precision, and performance in one thrilling package. Whether you’re a track-day enthusiast, a member of a motorsport country club, or a dedicated racer, the SR10 is designed to fulfill your need for speed while maintaining accessibility and cost-effectiveness.
