Longer ran ge missile

UK-based Radical Sportscars was one of the pioneers of the track day special market when it launched its 1100 Clubsport in 1997. Now, following some recent forays into road cars, and a management change in 2017, the company continues to go from strength to strength. Its best-selling car, the SR3, has shipped over 1300 units and the various one-make series running its cars are flourishing across the globe.

Where we are seeing the market moving is a longer range car, with increased durability and ease of use
James Scott, technical development manager at Radical Sportscars

According to James Scott, technical development manager at the company, even through the ongoing pandemic Radical has been seeing a boom in demand for its products, and the order books are currently full, including requests for its latest model, the SR10.

Radical’s cars have always been characterised by their high-revving, motorcycle-based engines. From the diminutive SR1, up to the raucous SR8, the company has largely developed its powertrains around motorcycle technology. However, for the SR10 it has diverged from this path and opted instead for a turbocharged in-line four, in the form of a 2.3-litre Ford EcoBoost engine. The lightweight four pot delivers 425bhp and 386ft.lbs of torque, which, thanks to the SR10’s all-up weight of 725kg, equates to a power-to-weight ratio of 586bhp per ton. This makes it the most powerful machine in Radical’s line up, pipping the SR8’s 411bhp.
