The Radical SR3 XX is a track-focused sports prototype developed by Radical Motorsport, introduced in 2020 as an evolution of the SR3 model. Designed for both amateur and professional drivers, it offers a lightweight chassis, LMP-inspired aerodynamics, and a high-revving Suzuki Hayabusa-based engine. The SR3 XX is available with two engine options: a 1,340 cc unit producing 195 bhp and a 1,500 cc version delivering 226 bhp, both paired with a six-speed sequential gearbox. It features advanced electronics developed with AiM Technologies, including a multifunction steering wheel with a built-in LCD display for real-time data. The vehicle achieves 0 to 60 mph in approximately 3.1 seconds and a top speed of 147 mph. In late 2022, Radical introduced the SR3 XXR, which includes a biofuel-ready engine producing 232 bhp, improved braking, and aerodynamic upgrades like a shark fin for better stability. The SR3 XX series combines cutting-edge technology with thrilling performance for an exceptional track experience.
