The SIN R1 is a sports car made by Bulgarian manufacturer SIN Cars.
Background
Rosen Daskalov, the founder of SIN Cars & former racing driver, was working with a British business partner in the United Kingdom in 2012. After disagreements they split and Daskalov moved the company to his hometown and continued developing the R1.[1]
Specifications
The R1 features an FIA-certified tube frame construction, being built around a strong, heavy and relatively easy-to-make tubular spaceframe chassis rather than a carbon fiber monocoque. It features carbon fiber bodywork and an active rear spoiler. It came with 3 engine choices – LS3 (6.2-liter N/A V8), LS7 (7.0-liter N/A V8) and an LS9 (6.2-liter supercharged V8).[2][3] The standard transmission was a 6-speed manual, with a sequential paddleshift gearbox offered on some models, sending power to a limited-slip differential.[4] The brakes are supplied by AP Racing and the dampers by Öhlins. It has double wishbone suspension all around with in-board mounted springs and dampers. The car weighs 1,250 kg (2,760 lb)[5] and has a top speed of 300 km/h (186 mph). The 7.0-liter naturally aspirated engine has its pistons and bearings replaced with high-performance items. A dry sump lubrication system is better fitted for track driving, which means the engine can be positioned lower in the chassis – and it uses a bespoke, part-titanium exhaust.
The R1 series includes 3 models (450, 550 & 650) for road and 2 models (VTX & GT4) for track. The first R1 was revealed in track-only prototype form in 2013 at the Autosport International show. In 2014, a road-going prototype was shown. The R1 will be produced no more than 20 units annually.
