As a boutique supercar manufacturer, Sin kind of has carte blanche when it comes to parts. The R1's engine, for example, is a 6.2-liter V8 from the Chevrolet Corvette. Situated in the back, the American engine is mated to the transmission from a Porsche 911 GT2. With 525 horsepower on tap from the LS3, the R1 has a claimed top speed of over 200 miles per hour and can hit 60 in just 2.5 seconds.
Helped along by a low curb weight of just 2645 pounds, the R1's speed shouldn't be a huge surprise. With aerodynamics (including a very meaty wing) producing upwards of 550 pounds of downforce and a 40/60 weight distribution, this is bound to be a car that can dance, so long as it's in a very talented pair of hands.
All that said, the Sin R1 is still something of a question mark. This is the only one we've seen, and there's no mention of pricing or availability. Sin made a name for itself building racing cars, but this is its first road-going model. It has the name-brand parts, with a steering wheel and seats from OMP, wheels from AP Racing, and Braid wheels. Only time will tell, though, if it's the next Koenigsegg or Pagani, or just another one-off that never found an audience.
