Chassis No. SA93SLL24CP207006

Radical Sportscars built its name on Britain's club-racing circuits, and the SR3 SL carried that formula onto the public road. Reportedly the sixth of 55 road-legal SLs built, this early example was imported by Radical Switzerland and served as the model's Swiss homologation car. It also retains the early cars' straight-cut gearbox, which shifts remarkably quickly. First registered in April 2013, it saw track-day use under its first owner before the consignor acquired it in 2015.

In 2019, EAS Fahrzeugtechnik rebuilt the engine with forged pistons and H-beam rods and fitted a larger Pro Alloy radiator and intercooler. Between late 2021 and early 2023, A&M Autotech und Motorsport reengineered the car over more than 285 hours, adding front radiators designed from a 3D scan, Haltech Nexus R5 engine management with a bespoke harness, port injection, and an electric water pump. An upgraded TTE turbocharger followed in 2024, and three steering-wheel-selectable maps now deliver approximately 240, 300, or 330 PS.

The consignor also commissioned the car's exposed carbon fiber body, which, unusually for full carbon bodywork, is homologated for Swiss road use. At a reported 680 kg, the SL has a power-to-weight ratio of roughly 2 kg per PS, comparable to a GT3 race car. Apart from a 2023 shakedown, it has reportedly not seen track use since its rebuild. The consignor has offered, at his expense, to deliver the car to A&M Autotech after the sale for a fresh service and Swiss inspection, where the buyer may collect it. Fully documented by invoices, this thoroughly sorted SR3 SL is as at home on the street as it is capable on track.
