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.
