Pagani Huayra

Performance

The Huayra uses a twin-turbo, V12 engine developed by Mercedes-AMG specially for the Huayra. The Huayra's 6.0-litre engine, the M158, produces 730 PS (720 hp, 539 kW) and 811 lb·ft (1,100 N·m) of torque. Its top speed is about 238 mph (383 km/h) and it has a 0-60 acceleration time of 2.8 seconds. Using Pirelli tires, the Pagani Huayra is capable of withstanding 1.66 g of lateral acceleration at speeds of up to 230 mph (370 km/h).

The Pagani Huayra uses a seven-speed sequential gearbox and a single disc clutch. The choice not to use a dual-clutch in an oil bath was due to the increase in weight of over 70 kg (154 lb), thus negating any advantage of the faster gear changes in a double-clutch transmission. As a result, the entire transmission weighs 96 kg (212 lb).

The car is equipped with Brembo brake calipers, rotors and pads. The calipers have four pistons in front and four in the rear. The rotors are drilled carbon ceramic, 380 mm (15.0 in) in diameter and 34 mm (1.3 in) thick.

Engine

Mercedes-Benz's AMG division provides the engine of the Huayra which is hand-built. The 5,980 cc, twin-turbo, 60° AMG M158 V12, has been designed at the request of Pagani to reduce turbo lag and improve response, realized with smaller turbos, a different intercooler configuration and re-programmed ECU settings.

Like many high-performance cars, the Huayra uses dry sump lubrication. This has several key benefits including guaranteeing oil flow even when the car is subjected to extreme lateral acceleration, preventing "oil surge" which allows the engine to operate more efficiently while the lack of an oil pan allows mounting the engine lower, lowering the car's center of gravity and improving handling. The fuel consumption of the Huayra is 10 mpg (23 l/100 km) in city and 14 mpg (17 l/100 km) in highway (EPA testing).

A water / oil heat exchanger reduces engine warm-up times on cold days and helps maintain a stable temperature for refrigerants and lubricants.

To minimize the use of pipes and fittings (and the overall weight of the vehicle), the expansion tank is mounted directly on the engine. Intercooler fins act as an expansion tank circuit at low temperatures.

The titanium exhaust system was designed and built by MHG-Fahrzeugtechnik. Hydroformed joints were developed to reduce back pressure and ensure a free flow exhaust. Titanium reduces the weight of the exhaust system while the Inconel silencers improve reliability in the most exposed parts of the exhaust at high temperatures. The entire system weighs less than 10 kg (22 lb).

Aerodynamics

The Pagani Huayra is different from its predecessor in that it incorporates active aerodynamics. It is capable of changing the height of the front from the ground and independently operating four flaps placed at the rear and front of the car. The behavior of the flaps is managed by a dedicated control unit that is fed information from systems such as the ABS and ECU, which pass on information about the car's speed, yaw rate, lateral acceleration, steering angle and throttle position. This is intended to achieve minimal drag coefficient or maximum downforce depending on the situation. The Huayra's designer Horacio Pagani states that it has a variable drag coefficient of between .31 and .37. The system also prevents excess body roll in the corners by raising the "inside" flaps (i.e. the left ones in a left-handed corner and vice versa), increasing the downforce on that side of the car. The rear flaps also act as an airbrake. Under hard braking, both the front suspension and the two rear flaps are raised to counteract weight transfer to the front wheels and keep the whole car stable, for instance when entering a corner. Air from the radiator is extracted through an arch in the bonnet at an angle that is designed not to affect the streamline around the body. The side air intakes behind the front wheels create a low pressure zone, resulting in downforce.

Official debut

The Pagani Huayra was officially debuted online with many pictures in a press release on January 25, 2011. The official world debut was at the Geneva Auto Salon 2011 in March.

EA secured the exclusive video game rights to the Pagani Huayra in 2011, available exclusively in Need for Speed titles in 2011, Shift 2: Unleashed and Need for Speed: The Run. This license expired on 31 December 2011. In 2012 it appeared in Need For Speed: Most Wanted at second place on the Most Wanted List. The Huayra also appears in Need for Speed Rivals as a racer vehicle. The Pagani Huayra also appears in the Jalopnik January DLC Car Pack for Forza Motorsport 4 along with other cars like the Ford Pinto, the Alfa Romeo Montreal and seven others. While all other cars in the pack can be purchased individually the Pagani Huayra can only be obtained by purchasing the whole pack. The Pagani Huayra was also featured in Asphalt 7: Heat, Asphalt 8: Airborne and in Forza Horizon Limited Edition, as well as CSR Racing, Assetto Corsa and Project CARS. The Pagani Huayra is also featured in Real Racing 3, Grid 2 and Grid Autosport. The Huayra is also playable in the Xbox One racing game Forza Motorsport 5, the PlayStation 3 racing game Gran Turismo 6 and the PlayStation 4 racing games Driveclub and "The Crew". A fictionalized version, branded the Pegassi Osiris, is included in the Ill Gotten Gains: Part 1 DLC update of Grand Theft Auto Online which was released on June 10, 2015.

The vehicle is used as an alternate mode for the Vehicon Stinger in Transformers: Age of Extinction film.

Huayra Roadster

After 2 years of development, the Huayra Roadster was officially unveiled in the 2017 Geneva Motor Show.

The appearance of the car has changed, with the most obvious being the open top (hence the Roadster name). This part of the vehicle is also its key element. The design of the rear changes, with new eyelid-like fixed flaps that continue with the design and eventually end on the rear lights. The rear engine hood also has a new shape to adapt to the roadster form. It also, unlike the Coupe, does not include a black carbon-fiber stripe across it. The engine hood also now has grilles. The wheels also change, with a new set specifically constructed for the Roadster model. There is now also a front spoiler. The doors are no longer gull-wings, as this is a convertible version of the Huayra.

The vehicle still runs on the same M158 V12, but now has a total of 764 PS (562 kW; 754 hp) at 6200 rpm and 1,000 N·m (740 lb·ft) of torque at 2400 rpm. All of this power is delivered to the rear wheels via an all-new 7-speed automatic manual transmission by Xtrac. The car now uses a hydraulic and electronic activation system with carbon synchronizers. Bosch have also done some help for the Roadster, constructing ECUs and electronic differentials for it, giving it increased drivability. The entire system weighs 40% less than the gearbox. The weight is now 70 kilograms lighter, for a total of 1,280 kg (2,820 lb), making the first roadster lighter than the coupe version. There will be only 100 Huayra Roadsters made and all of them have already been sold. The tire supplier is Pirelli, with P-Zero tires. the tires also have a white narrow outline, resembling the F1 race car tire lines. Pagani has also used a new material for the Roadster called carbon triax, which is a tri-axis fiberglass meshed with carbon-fiber power bands.

Pagani says the car can do 820 kilograms (1,800 lb) or 1.8 lateral G-forces during acceleration. However, this figure is unproven, but if true, Pagani will have set a new record.

Special editions

Pagani has made several special edition Huayras.

Carbon Edition

The first special edition was the Pagani Huayra Carbon Edition, unveiled in 2012, along with the White Edition. It features a full carbon fiber build on the wheels, body, and most of the interior, hence the "carbon" part of the name. The interior features red leather wrapping and carbon fiber inserts. The specifications are the same as the standard Huayra.

White Edition

The White Edition was unveiled in 2012, along with the Carbon Edition. The car features a white and carbon fiber exterior, a white and black interior, and aluminum wheels.

La Monza Lisa

This special edition Huayra, called "La Monza Lisa", was another special edition of the Huayra. It features tricolore racing stripes and side stripes inspired by the Zonda Revolucion, and a bright red interior with white stitching inspired by a Zonda F Roadster. At the customer's request, Pagani also reengineered the firewall behind the occupants to be finished in a mixture of matte and gloss fully exposed carbon fiber, for visual effect as well as to pass more engine vibration through to the carbon fiber seat backs, per the customer's request.

Da Vinci

The Da Vinci / 730S special edition was unveiled at the AutoGallery of Beverly Hills in February 2015. The car was built in a collaboration between Pagani and Alejandro Salomon.

The first owner of the car was Alejandro Salomon, but was later sold to David Lee, a well known Ferrari collector, due to Salomon's complaints after driving it for a year. The car was later renamed "Da Vinci" by Lee after his purchase.

Huayra BC

An even more extreme version called the Huayra BC model debuted at the Geneva Motor Show in March 2016. The Huayra BC is named after the late Benny Caiola, a friend of Horacio Pagani, and the first Pagani customer. The Huayra BC has an improved version of the standard Huayra's 6.0 liter V12, twin turbocharged AMG engine, and now produces 800 PS (590 kW; 790 hp) as well as 1,100 N·m (810 lb·ft) of torque. The dry weight is now reduced to just 1,218 kilograms after a 132 kilogram decrease in weight, thanks to a new type of carbon fiber that Pagani claims is 50% lighter and 20% stronger than regular carbon fiber. Pagani have also fitted the Huayra BC with a lighter titanium exhaust system, new aluminum alloy wheels, and a stripped out interior. The tires are Pirelli P Zero Corsas that feature 12 different rubber compounds, and the suspension and wishbones are made of aeronautical grade aluminum, known as Avional. The Huayra BC also has a new front bumper with a splitter and winglets, deeper side skirts, and an air diffuser that stretches the entire width of the rear bumper, and a massive rear wing. All the components are made of carbon fiber, and are add-ons. The Huayra BC also has changes made to all but one of the body panels to maximize downforce and minimize drag. The Huayra BC uses a next-generation 7-speed manual gearbox, and has an electro-hydraulic actuation. Pagani has stuck with a single-clutch gearbox because it weighs 40% less than double-clutch gearboxes.

All 20 units of the €2.3 million Huayra BC coupé have been sold out, and orders are already stacking for the BC roadster.

Pearl

The Huayra Pearl, unveiled in May 2016, was another special edition of the Huayra. It features the split rear wing inspired by the old Pagani Zonda C12 cars, and the roof air scoop inspired by the Pagani Zonda Cinque. Like the Carbon Edition and Da vinci, the car is built on a woven carbon fiber body. It was involved in an accident in Paris in July 2016.

Dinastia

The Huayra Dinastia was another special edition Huayra revealed to the public in 2016. Horacio Pagani's inspiration for this car came from the Nine-Dragon Wall in China. There were only going to be 3 units of this car being sold, but after October 2016, there are now 4 of them. Each unit will also have a certain livery. The design of the car reflects Horacio's visit with each unit's livery design resembling one of the dragons on the wall, and it also has an aerodynamic fin on the rear, mostly likely to resemble a dragon's tail. In October 2016, Pagani decided to build a fourth Dinastia to the collection, in a purple carbon livery. This particular Dinastia has the Tempesta package.

The liveries of the cars are:

All four cars will still have the same specifications as the standard Huayra.

Rumors of new Huayra

There have been rumors that a new special edition Huayra will be made, and that it will celebrate 100 Huayras built from the factory. Pagani has already been uploading videos and photos of the new car in their website to show that this special edition is in the works.
