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 (594 hp/443 kW) with a special clubsport model producing 650 PS (641 hp/478 kW). 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 top speed can be further tweaked by adjusting the aerodynamic settings. 215 mph (346 km/h) is the car’s top speed on the setting for the best handling which provides the most down force but also has the highest drag coefficient. If the aerodynamic settings were adjusted the top speed would be a bit higher. This also seems to be the reason that when EVO Magazine attempted the Pagani Zonda S’s top speed on the Autobahn, that they were only able to get the car to 197 mph (317 km/h), as opposed to its claimed top speed of 220 mph (350 km/h). It would make sense that if the car was set up for maximum downforce then its top speed would drop to around 200 mph (320 km/h). Company representatives at Pagani’s factory backed up this claim. However, the EVO article claimed that aerodynamic parts, specifically ones which created drag were in fact removed during the run, bringing Pagani’s claims into question.
