The Pagani Zonda R[1] is a track day car developed and manufactured by Italian sports car manufacturer Pagani. It debuted at the 2007 Geneva Motor Show, using the 6.0-litre GT 112 engine sourced from the racing version of the Mercedes-Benz CLK-GTR.[2] The Zonda R's competition lies with track-based cars, such as the Ferrari FXX and Maserati MC12 Corse rather than the original Zonda's road competitors as it is not road-legal.
Despite sharing much of the Zonda's shape, the R is almost entirely new, sharing only 10% of the Zonda F's components. It has been obliquely suggested by Horacio Pagani that this car is a testbed chassis for certain components of the Zonda's replacement, the Huayra (in the same vein as the Ferrari 288 GTO Evoluzione and the successive F40) and that the Zonda R accurately reflects some of the Huayra's features. Only 15 Zonda Rs were produced along with an additional 5 Zonda Revolución cars and the Zonda R prototype.
Chassis
The central carbon chassis incorporates a roll cage and a rubber racing fuel cell with 4 fuel pumps and quick refuel filler cap, similar to GT race cars. The wheelbase has been increased by 47 mm (1.9 in) to increase stability. The front and rear subframes are brand-new, built to accommodate new suspension geometry, and produced in Avional. The slick-shod wheels are new forged-magnesium center-lock models, which in conjunction with on-board pneumatic airjacks allow rapid change of the entire wheel assemblies.
The car senses, displays and logs information about the amount of down-force that is generated at each wheel at all times. It is thought that this system will enable owners to adjust set-up according to track conditions and to improve their cornering technique.
Bodywork
In addition to the wheelbase increase (47 mm), overall length has increased by 394 mm (15.5 in) and track by 50 mm (2.0 in). The bodywork and aerodynamics have been altered to offer maximum down-force, featuring a longer front bonnet with flaps, a closed underbody and a new rear overhang with adjustable rear wing and race-derived diffuser. These are intended to translate into increased aerodynamic efficiency and down-force for maximum cornering speed. It is also noted that the car's new rear bodywork is minimal in the extreme, being composed mostly of vent. This is thought to be symptomatic of the need to keep the engine cool enough, even under hard track use.[3]
Engine

The engine, although shared with the Mercedes CLK-GTR, has been modified and has an increased power output of 750 PS (552 kW; 740 hp) at 7,500 rpm and 710 N⋅m (524 lb⋅ft) of torque. And a specific power output of 125 PS/litre. A lightweight carbon fibre high performance intake system, racing multiple disc centered clutch and Formula One-style exhaust system, hydroformed in Inconel 625 and ceramic coated for optimal heat dissipation, have been added. The AMG-built engine is mated to a 6-speed longitudinally-mounted manual sequential synchronized gearbox manufactured by Xtrac.[4]
Interior

The car's interior is mainly composed of track-related features and minimum creature comforts, reflecting the car's racetrack aspirations. It also features seats specifically customized to the body dimensions of its respective owner to offer maximum support to the owner while in use. As before, the Digitek instrumentation provides essential information and the sophisticated telemetry allows a variety of sensors to monitor numerous aspects of the car.
Performance
Track records
On 30 June 2010, Pagani claimed a new record for production-based cars using the Pagani Zonda R and completing the Nürburgring in 6:47, beating the Ferrari 599XX.[5][3]
The Zonda R completed a lap of the Top Gear test track in 1:08.5, but it was disqualified from the Power Lap board on the basis of it not being road legal. This marks the 3rd fastest car to ever go on the Power Lap leaderboard.
