The LMP (Le Mans Prototype)-inspired two-seat SR1 aims to widen Radical's automotive enthusiast audience beyond hardcore racers to those looking to take circuit driving to the next level with a more focused sports car ideal for trackdays, club level motorsport, hillclimbs and sprint events.
Developed by the same manufacturer that created the Radical SR9 LMP2 racecar and SR3 'road car', the SR1 sports a carbon steel spaceframe and lightweight fibre-glass bodywork to keep the mini-racer's weight down to just 520 kg.
The SR1's 154kW/176Nm Suzuki-sourced 1.3-litre four-cylinder motorbike engine combines with a six-speed sequential gearbox, lightweight flywheel and Quaife ATB limited-slip differential to see 100km/h come up in 3.6 seconds before hitting a top speed of 222km/h.
Helping to bring all that go to a 1.8g-enducing stop are the more than ample 240mm ventilated disc brakes with four-pot calipers fitted both front and rear. A comprehensive FIA-approved safety cell, racing harnesses, integrated fire extinguisher system, fully adjustable pedal box, fully adjustable suspension, brake bias adjuster and Radical-specific optional Dunlop slick, wet and road tyres all ensure this play-thing isn't just a toy.
Radical co-founder Phil Abbott said, "The SR1 is brilliant fun to drive and the performance is readily accessible for drivers of all abilities and ages".
While not legal on Australian roads and with Radical Australia yet to decide if they will bring it in, the £29,850 ($46,410) Radical SR1 still makes for a tempting track-day-only purchase.
