Pagani Zonda C12 S Roadster 2003

The Zonda C12 F debuted at the 2005 Geneva Motor Show. It is the most extensive reengineering of the Pagani car yet, though it shares much with its predecessors including the 7.3 L V12. Power is increased to 602 PS (443 kW; 594 hp) with a special clubsport model producing 650 PS (480 kW; 640 hp). The company promises a 3.5 second sprint to 62 mph (100 km/h), a top speed over 215 mph (346 km/h). The Zonda F clubsport has a power to weight ratio of 528 bhp/ton (384 W/kg). An Enzo Ferrari, comparatively, has a power to weight ratio of 483 bhp/ton (356 W/kg).

The Zonda F Clubsport lapped the Nurburgring, in 7 minutes 27.82 seconds, beating the Porsche Carrera GT. It was surpassed by the 2009 Corvette ZR1 on 7 June 2008, with a time of 7 minutes 26.4 seconds.[3] With Marc Basseng at the wheel the Zonda F CS has set a new time around the Nurburgring, lapping the 12.9 miles (21 km) Nordschleife in 7:24.7 now only surpassed by the Maserati MC12 which set a time of 7:24.3, the Dodge Viper SRT-10 ACR with a time of 7:22.1. and the Radical SR8LM with a record time of 6:48.

Production of the Zonda F will be limited to 25 cars, not US compatible. The next model (codenamed C9), due to be unveiled in 2009, will be fully EPA/DOT compatible.

The Zonda F, named after Formula One driver Juan Manuel Fangio, comes with an extra head light and different fog lights at the sides, new bodywork (revised front end, new rear spoiler, more aerodynamic vents all around) that improves the cars aerodynamics and different side mirrors. Further enhancements over the 'S' centre around optional carbon/ceramic brakes developed in conjunction with Brembo, magnesium wheels, inconel titanium exhaust system, hydroformed aluminum intake plenum and a redesigned 'Z preg' weave in the crash structure to improve rigidity and reduce weight.
