SIN R1

The R1 features an FIA-certified tube frame construction, carbon fiber body and an active rear spoiler.

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.

It is built around a strong, heavy and relatively easy-to-make tubular spaceframe chassis rather than a carbon fiber monocoque.

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.

A sequential paddleshift gearbox and a traditional six-speed manual can be chosen freely, and the car has a limited-slip differential.
