Corvette-Powered Sin R1 Road Car Enters Production: Video

We first caught wind of the Sin R1 supercar in 2013. Back then, it was still a track-only car and its maker, Sin Cars, was based in Munich, Germany. Since then the company has moved to Bulgaria, and the R1 has spawned a road-going version known as the R1 RS. The first example of the Sin R1 RS is now being shown to potential customers ahead of an official world debut at the 2015 Frankfurt Auto Show in September.

Sin started out building race cars for private customers, usually as rolling chassis, but eventually decided to expand into the world of turnkey models. The company works closely with British firm ProFormance Metals to develop its cars, with the latter primarily responsible for building the lightweight chassis underpinning them. Available powertrains, meanwhile, will be familiar to any Corvette fan.

The chassis is a tubular spaceframe design, and wrapped around this is a carbon fiber body. The engine is mid-mounted, with Sin offering three performance levels. The standard option is General Motors Company’s [NYSE:GM] 6.2-liter LS3 V-8, rated at 430 horsepower. Those seeking more power can opt for a 530-hp 7.0-liter LS7 or even the 650-hp supercharged 6.2-liter LS9.
