WTF, I hear you ask. There was only one generation of Porsche 959 and it had 450 horsepower, I hear you say. And you’re right. But you see, this right here is no ordinary 959. This is Bruce Canepa’s personal and extremely special 959, and it’s mind-blowing how amazing this car is.

As for that Gen III thing, well, that refers to the third stage of upgrade implemented on this car. Mr Canepa bought this car new back in 1988 with the standard 450 horsepower. Obviously, he wasn’t happy with it, because the other 292 unit also had the same power. So over the years he kept upgrading the car and added more power until he reached this Gen III version with 763 horsepower and 635 ft-lb of torque (Gen I had 576 hp and Gen II 640 hp).

This car is what, Canepa believes, the 959 would have become had Porsche continued its production.

In order to get 763 hp from the 959’s flat-six turbo engine, Canepa engineers and technicians got rid of the factory turbochargers and installed all-new parallel twin-turbo system including new Borg-Warner turbos, integrated wastegates, and titanium heat shields. Intakes, outlets, exhaust, camshafts, ignition, fuel system, air filters, engine management, air pumps and air regulator valves, spark plugs, idle control valve, sensors, connectors, harness shielding, switches, adapters, wiring harness, and… are among the other parts either upgraded or replaced with a better unit.

Other highlights of Canepa’s Gen III Porsche 959 include S-spec coilover suspension, upgraded magnesium wheels, and a sweet interior trim with a chocolaty brown leather and Alcantara that cover pretty much every visible surface.
