The SIN R1 is a sports car made by Bulgarian manufacturer SIN Cars. The R1 features an FIA-certified tube frame construction, carbon fiber body and an active rear spoiler. It came with 3 different engine choices – LS3 (6.2-liter N/A V8), LS7 (7.0-liter N/A V8) and an LS9 (6.2-liter supercharged V8). The only transmission offered is a 6-speed manual. The car weighs just 1,250 kg (2,760 lb) and has a top speed of 300 km/h (186 mph).

The dimensions are L x W x H: 4,830 mm (190 in) x 2,000 mm (79 in) x 1,285 mm (50.6 in), with a wheelbase of 2,760 mm (109 in).

Background

Rosen Daskalov, the founder of SIN Cars & former racing driver, was working with a British business partner at The United Kingdom in 2012, but after a number of disagreements they went their separate ways. Daskalov also moved the company back to his hometown and continued developing the R1.[1]

Model information

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 models annually. It is built around a strong, heavy and relatively easy-to-make tubular spaceframe chassis rather than a carbon fiber monocoque. Nonetheless the car is still light at around 1,250 kg (2,760 lb).[2]

There are 3 different engines - GM LS-based (6.2-liter N/A V8, 7.0-liter N/A V8 & 6.2-liter supercharged V8) for choices.[3][4] The 7.0-liter naturally aspirated engine tested here 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 bodywork of the R1 is all carbon and the rear wing is active. 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. A sequential paddleshift gearbox and a traditional six-speed manual can be chosen freely, and the car has a limited-slip differential.[5]
