Zonda R
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.[17] The Zonda R's competition lies with track-biased 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 (in the same vein as the
Ferrari 288 GTO Evoluzione and the successive F40) and that the Zonda R accurately reflects some of the Zonda's successor's features. Only 15 Zonda R were produced.
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 (again, like the
FXX) allow rapid change of the entire wheel assemblies.
The car senses, displays and logs information about the amount of
downforce 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 downforce, 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
downforce 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.
Engine
Zonda R engine (Mercedes-Benz M120 AMG)
Output has increased to 750 PS (552 kW; 740 hp) at 8500 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.
Interior
The car's interior is spartan reflecting the car's racetrack
aspirations and intended home, and features bespoke 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.
Zonda R Evolution
The Zonda R Evolution 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 hp. The body work is still the same but has improved
aerodynamics. It features a bigger air spliter above the two standard
air spliter on the front bumper and a pair of small splitter on the
sides of 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 downforce
