The Zonda R debuted at the Geneva Motor Show 2007, using the 6.0 litre V12 M120 engine sourced from the race version of the Mercedes-Benz CLK-GTR. The Zonda R's competition lies with track-based cars, such as the Ferrari FXX and Maserati MC12 Corsa rather than the original Zonda's road competitors as it is not road-homologated.
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 Pagani 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 R were produced.
The Pagani Zonda R has a top speed of 218 mph (350.8 km/h), accelerates to 0 to 60 mph (0.0 to 96.6 km/h) in less than 2.7 seconds, can brake from 60 to 0 mph (96.6 to 0.0 km/h) in 96.0 ft (29.3 m), and corners at 1.62g.
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 (again, like the FXX) 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.
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. Again, this is similar to the gutted bodywork of the Ferrari FXX Evoluzione.
Output has increased to 750 PS (552 kW; 740 hp) at 7500 rpm and 710 N⋅m (524 lb⋅ft) of torque. 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.
The car's interior is spartan, reflecting the car's racetrack aspirations and intended home, and features seats customized to the driver to offer maximum support. As before, the Digitek instrumentation provides essential information and the sophisticated telemetry allows a variety of sensors to monitor numerous aspects of the car.
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.
Zonda R Evolución
The Zonda R Evolución is an updated version of the Zonda R. It features many changes over the previous Zonda R. Also the car takes many pieces and inspirations from the Zonda 760RS. It is finished in pearl white with exposed carbon-fibre on the nose. The 6.0L V12 engine is uprated to 800 PS (588 kW; 789 hp). The bodywork is still the same but has improved aerodynamics. It features a bigger air splitter above the two standard air splitters on the front bumper and a pair of small splitters on the sides of the rear bumper. A bigger rear central fin — even bigger than the 760 series Zondas — and a small spoiler added below the standard Zonda R spoiler improves aerodynamics and increases down-force.
Pagani unveiled the final version of the Zonda R, called Zonda Revolución to clients and family members during "Vanishing Point 2013", the International Pagani gathering. The central monocoque is carbon-titanium, the needle on the scale stops at 1070 kg. The Mercedes-AMG engine is an evolution of the Zonda R powerplant. The 6.0-liter V12 now develops an output of 800 PS (588 kW; 789 hp) and 730 N⋅m (540 lbf⋅ft) of torque,resulting in a power to weight ratio of 748 hp per tonne. The Xtrac 672 6-speed transversal and sequential gearbox changes gears in 20ms. The traction control developed by Bosch with 12 stage traction control and the renewed ABS system, allows the vehicle to further adapt to the driver's driving style. The aerodynamics feature new and updated canards on the front, as well as a vertical stabilizer supporting the main rear wing. Beside using R Evolución's body, the Zonda Revolución also features a DRS (Drag Reduction System) on the rear wing. The system has two different operating modes, both can be activated by the driver at any time. The manual system is controlled with the DRS button on the steering wheel. The rear wing changes between maximum and minimum down-force settings, at the occurrence of a lateral acceleration of 0.8 g and a minimum speed of 100 km/h (62 mph). Holding down the DRS for more than two seconds engages the DRS to work automatically according to the algorithms developed by the Pagani engineers during the development phase. The main rear wing also utilises mounts on the side of the vehicle alongside a smaller wing at the end of the vertical stabiliser. The Brembo braking system adopts new CCMR discs derived from F1 technology. With a weight saving of 15% compared to the previous CCM discs, the CCMR offer higher stiffness and lower operating temperatures on extreme track use. This contributes to the life of the disc which is increased by four times, with no sign of fading and a significant overall increase in braking power. Each Revolución, of which only five were built, was priced at €2.2 million before taxes.
