2023 Radical SR10 XXR has new front louvres that improve the car’s aerodynamics at high speeds, reduce understeer, and enhance cooling. Inspired by LMP racers, and also fitted to the SR3 XXR, the central fin is another novelty of the model. The high-intensity daytime running lights are standard, and so are the new lightweight alloys. Customers who want even more weight reduction can order the new carbon splitter and diffuser package as an optional extra.

Powering the SR10 XXR is the same Ford EcoBoost 2.3-liter four-cylinder engine, retuned in-house and fitted with bespoke turbocharger and management package, and hooked up to a Hewland GT3-derived six-speed gearbox. The result is 425 horsepower (431 ps/317 kW) and 380 pound-feet (515 Nm) of torque available via the right pedal, a quick look on the company’s official website reveals. This means that the output and thrust are identical to the normal SR10, which needs roughly 2.5 seconds to hit the 60 mph (97 kph) mark from a standstill, before running out of breath at 180 mph (290 kph).
