Radical SR10 smashes sales records

Radical Sportscars says that its latest offering, the SR10, has become the fastest-selling model in the company’s history. Having only launched in September 2020, 50 SR10s have been sold to date; the company’s SR8 model took four years to reach the same milestone.

The SR10 was designed to be a more driver- and endurance-event-friendly option than the SR8; as such, it features a turbocharged I4 rather than a highly strung V8. The Radical-developed Ford EcoBoost 2.3-liter turbocharged engine arrives as a crate engine from Ford, before being stripped to its core components, with the block machined and strengthened ready for forged internals, a dry sump, larger, custom-built Garrett turbo and a bespoke exhaust manifold.

The result is over 425bhp and 380 Ib-ft of torque. Radical notes that the unit was developed to be a high-output, long-life powertrain to help keep running costs low, with longer maintenance intervals than its competitors. To increase durability and performance, Radical turned to transmission and transaxle specialist Hewland for the six-speed transmission, which was originally developed for use in FIA F2 single-seaters.

Radical claims that with its digital dash and full datalogging capabilities, including video and telemetry, the SR10 can assist the progress of drivers and driver coaches. A clear example of how this plays out can, says Radical, be found in the Radical Cup in North America, where the SR10 has dominated the series, winning every round so far.

Steve Cameron, co-owner of Radical’s Northwest US dealership and two-times Daytona 24hr class winner, commented, “It has been an incredible first year for the SR10. The performance of the car is unparalleled and it’s not just something I’ve noticed as a racer, but so have our customers as well. It is the most competitive Radical out there at the moment and has shown that time after time, particularly in the Radical Cup we have over on this side of the Atlantic. The season is not over just yet, but we have already seen an increase in interest from those who have seen it on track. 2022 looks very strong.”
