The British sports car maker Radical announced launch of a new entry-level SR1 model for club racer and trackday driver on a budget. The SR1 costs just under £30K, and offers an LMP style race car with superb performance thanks to a 210bhp RPE-Suzuki four-cylinder engine. The lightweight Radical can outperform almost all the super cars and GTs on the race track with its unique handling characteristics and cornering capabilities.
Besides the magical chassis and the reliable powertrain, the SR1 also benefits from 240mm, 30-vane ventilated discs with four-pot calipers, a comprehensive safety cell and deformable crash structure tested to FIA standards, racing-specification harnesses and an integral fire extinguisher system. Superior grip is guaranteed with not only enhanced aerodynamics, but also the Radical-specific Dunlop slick, wet and road tyre options.
The running gear includes a six-speed sequential gearbox as standard, with a Quaife ATB differential. The 480 kg SR1 does 0 to 60 mph in 3.8 seconds and has a top speed of 138 mph. It is capable of generating maximum cornering G’s of 2.3, which is very remarkable.
The car’s official pricing is £29,850+VAT. It is impossible to go faster, and have more fun on a race track, for less.
