Pagani Zonda Roadster F

The Pagani Zonda Roadster F debuted at the 2006 Geneva Motor Show. Exterior wise the roadster was similar to the coupé, but with a removable carbon fibre roof and canvas side curtains, weighing just 5 kg more than the coupé. Power output of the engine increased to 650 PS and 780 N.m of torque, and production was limited to 25 units. The Roadster F maintained chassis rigidity without any gain in curb weight, eschewing conventional thinking by not strengthening the sills, a process which would have needed more than 35 kg of reinforcement. Pagani instead used racing car materials and construction techniques, strengthening the firewall structure of the chassis tub together with billet alloy braces, and the windscreen was strengthened for safety.
