Pagani Zonda

The Pagani Zonda is a supercar built by the Italian manufacturer Pagani. It debuted in 1999, and production ended in 2011, with three special edition cars, the Zonda 760RS, Zonda 760LH and the Zonda 764 Passione, being produced in 2012. By June 2009, 135 Zondas had been built, including test mules. Both 2-door coupe and roadster versions have been produced. Construction is mainly of carbon fiber.

Some of the early Zonda engineering was done by Formula One champion Juan Manuel Fangio. The car was originally to be named the "Fangio F1" after him but, following his death in 1995, it was renamed for an air current above Argentina.

Zonda C12

The Zonda C12 debuted in 1999 at the Geneva Motor Show. Powered by a 6.0 L (366 cu in) Mercedes-Benz V12 engine producing 394 PS (290 kW; 389 hp) at 5200 rpm and 570 N·m (420 lb·ft) at 3800 rpm mated to a 5-speed manual transmission gearbox. The C12 could accelerate to 60 mph (97 km/h) in 4.2 seconds and to 100 mph (160 km/h) in 9.2 seconds.

Just five of the original 6.0 L Zondas were built, though it was still available in 2002 when the C12 S debuted. One was used for crash testing, while another was a demonstrator and show car. The remainder were delivered to customers during the next three years. A woman from Sweden is confirmed to own the last remaining Zonda C12, with rejecting the offer from Pagani himself to redeem the car for historical reasons

Zonda S

The Zonda S uses a 7.0 L (427 cu in) AMG–tuned version of the engine producing 550 PS (400 kW; 540 hp). It can accelerate to 62 mph (100 km/h) in 3.7 secs, to 100 mph (160 km/h) in 7.5 secs and complete the quarter mile in 11.3 secs. Lateral acceleration on the skidpad is 1.18 g (11.6 m/s²), it can reach a top speed of 208 mph (335 km/h), and carries a price tag of US$500,000.

The Zonda S features an elongated nose, flaps at the rear for improved aerodynamics, and new light clusters and exhausts. Only fifteen 7.0 L Zonda S cars were produced.

Zonda S 7.3

The Zonda S 7.3 of 2002 used a new, larger V12 engine displacing 7.3 L (445 cu in) designed and manufactured by Mercedes-Benz AMG producing 555 PS (408 kW; 547 hp) and 750 N·m (550 lb·ft). And to better handle the power, traction control and ABS were made standard. Performance claims were unchanged from the Zonda S.

In February 2003 the UK automotive magazine Evo attempted a top speed run on the Autobahn in which the car topped out at 198 mph (319 km/h), 10 mph (16 km/h) off the mark of its claimed top speed of 208 mph (335 km/h). Company representatives at Pagani's factory claimed this was the result of the car being in the setting for maximum down force, something that would drop its top speed to around 200 mph (320 km/h). 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.

Zonda Roadster

In 2003 Pagani presented the Was upa Roadster, a roadster version of the Zonda S 7.3. Carrying the same components as the coupe, Pagani promised no loss of performance, a claim supported by the minimal weight gain of 30 kilograms (66 lb). A total of 40 roadsters were produced

Zonda F

The Zonda F (or Zonda Fangio) debuted at the 2005 Geneva Motor Show. It is the most extensive re-engineering of the Zonda yet, though it shares much with its predecessors including the 7.3 L AMG V12 engine which through enhanced intake manifolds, exhaust and a revised ECU now produces 602 PS (443 kW; 594 hp) at 6150 rpm and 560 lb·ft (759 N·m) at 4000 rpm.

Production of the Zonda F was limited to 25 cars. Named after Formula One driver Juan Manuel Fangio, it came equipped with an extra headlight and different fog lights at the sides, new bodywork (revised front end, new rear spoiler, more aerodynamic vents all around) that improved the car's aerodynamics, and different side mirrors. Further enhancements over the 'S' centered 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.

Zonda Roadster F

The Zonda Roadster F debuted at the 2006 Geneva auto show. It was similar to the coupe, but with a removable carbon fibre roof and canvas side curtains weighing just 5 kilograms (11 lb). Production of the Roadster F was limited to 25 units.

The Roadster F is able to maintain chassis rigidity without any gain in curb weight by eschewing conventional thinking by not strengthening the sills - a process which would have needed more than 35 kilograms (77 lb) of reinforcement. Pagani instead uses racing car thinking, materials and construction techniques, strengthening the firewall structure of the chassis tub together with billet alloy braces that connect the points where the roof rails would have joined. The windscreen is also strengthened for safety reasons. These techniques enable the Roadster to have virtually the same weight as the coupe, 1,230 kilograms (2,710 lb).

The Zonda Roadster F Clubsport was tested by Top Gear's The Stig and James May and achieved a lap time around their test track of 1:17.8, beating the Bugatti Veyron 16.4 tested during the same episode, but lost in a quarter mile drag race against the Veyron by nearly 2.5 seconds. According to James May, the Zonda F Roadster costs £825,000. German racing driver Marc Basseng managed to lap the Zonda F Clubsport around the 20.8 kilometres (12.9 mi) Nürburgring Nordschleife in 7:24.7.
