The Pagani Zonda GR is initially based on the Pagani Zonda "S", and was built on a basis of a carbon chassis, with in the front as well as at the rear a tubular frame. The modified bodywork, including front and rear diffuser and louvers, has the most excellent aerodynamic results. The total width of the car was brought to 2 meters, according to the regulations of both FIA and ACO. The weight of the Pagani Zonda GR was reduced to 1100kgs and also the team developed a completely new suspension with double supporting beams. The central locked wheels also were especially made for this Pagani Zonda GR, as well as the carbon brakes, that should allow the car to reduce the braking distance. The strong and powerful engine was equipped with an extra large radiator. Engine and gearbox also have a heat exchanger for the oil.
