The Sin R1 road car, a 444bhp lightweight sports car, is on sale for £72,000.
The V8-engined sports car, which was revealed in pre-production form but described as being "very close" to the final product late last year, will be assembled in the UK. The R1 road car is a collaboration between Sin Cars and British supplier ProFormance Metals.
Powering the R1 is a Chevrolet-sourced 6.2-litre V8 engine producing 444bhp. Sin says the R1 has a top speed of around 170mph and that it's capable of 0-62mph in just 3.5sec. Officials also claim the R1 is capable of returning up to 24mpg.
The V8 is mated to a six-speed manual transmission, which drives the rear wheels. Paddle-shifted sequential options will be introduced in the future. The car weighs 1100kg, and uses an FIA-homologated tubular spaceframe chassis. Its aerodynamic bodywork is made of carbon composites.
Other features include bespoke 19-inch alloy wheels, performance brakes, a Formula 1-style FIA-approved fuel tank, adjustable double wishbone suspension and an interior that features carbonfibre trim and two leather sports seats with racing harnesses.
The road-going R1 is the sister car to Sin’s GTB racer, which this year competed in the GT Cup Championship, driven by company boss Rosen Daskalov.
The racing version, which costs £110,000, features unique bodywork and a modified chassis, but Sin officials stress that the road car uses many of the same technologies developed for the racer. A GT4-class Sin car is also in development.
The track-only racing version of the R1 made its debut at the Autosport show in 2013, and made its dynamic debut at the Goodwood Festival of Speed. An early prototype model of the road-going R1 was revealed at the Autosport show in January 2014.
