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 Paganis 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 Switzerland is confirmed to own the last remaining Zonda C12, rejecting the offer from Pagani himself to redeem the car for historical reasons.
Zonda C12, small from the outside and comfortable on the inside, reveals to its passengers an exclusive universe where dreams and reality cross paths thanks to the interior details inspired to past, present and future cultures. The struggle and ambition involved in the creation of a timeless automobile that is able to trigger powerful emotions in virtue of its well-proportioned forms and details, is the key element to the meticulous research for an elaborate, technical design, where great attention is paid to even the most negligible and technical detail.
