Sorry to bring her back from the dead, but I'm having a hard time believing that this car will be faster than the McLaren F1, as previously reported:
"The Carrera GT has a pure racing engine. Its 10-cylinder powerplant with dry-sump lubrication is based on Porsche’s 5.5-liter V10 naturally aspirated engine developed especially for racing. For production, technicians at the Development Center in Weissach, Germany, have increased the displacement to 5.7 liters. Maximum output is 612 horsepower (DIN*) at 8,000 rpm, with peak torque rated at 437 pound-feet. The Carrera GT has a top test-track speed of 205 miles per hour (330 k/h) and accelerates from zero to 62 mph (100 km/h) in 3.9 seconds. Its specially developed six-speed manual gearbox allows it to go from zero to 124 mph (200 km/h) in 9.9 seconds.
The specifications demanded a consistent lightweight construction and sports car dimensions. With a length of 15.12 feet (4.61 meters), a width of 6.3 feet (1.92 meters), a height of 3.81 feet (1.16 meters) and a wheelbase of 8.96 feet (2.73 meters), the roadster weighs 3,042 pounds (1,380 kilograms). "
Only 205 mph? Weaksauce

But the McLaren got to 220 (I think), so it looks like it still owns the crown for fastest production car in history.
