Porsche 911 GT1

The Porsche 911 GT1 was a racing car designed for competition in the GT1 class at the 24 Hours of Le Mans and sold as a road car for homologation purposes. The roadgoing version was labeled the 911 GT1 Straßenversion (Street version).
Regulations for the GT1 category stipulated that to be eligible, a total of 25 cars must be built for road use. Porsche developed a fully road-legal version of the GT1 and delivered one in early 1996 to the German government for compliance testing, which it passed.
The engine had to be slightly de-tuned to meet European emissions laws, although its 544 PS (400 kW) and dry weight of 1100 kg (2425 lb) proved to be more than adequate; the vehicle could accelerate to 100 km/h (62 mph) from a standstill in 3.5 seconds on its way to a top speed of 310 km/h (193 mph).
