The Pagani Huayra (Italian pronunciation: [ˈwai̯ra]) is an Italian mid-engined sports car produced by Pagani. Succeeding the company's previous offering, the Zonda, it costs €1,198,000 ($1,314,000), (£910,905). It is named after Huayra-tata, a Quechua wind god. The Huayra was named "The Hypercar of the Year 2012" by Top Gear magazine and received a very positive review when tested by Richard Hammond on Top Gear. The Huayra was previously the fastest road car to go around the Top Gear Test Track, setting a time of 1:13.8, beating the previous record of 1:15.1 set by the Ariel Atom V8 in January 2011, but was beaten by the McLaren 675LT in June 2016 that set a record of 1:13.7.
On February 11, 2015 it was reported that the Pagani Huayra has been sold out. The Huayra was limited to just 100 units as part of Pagani's agreement with engine supplier Mercedes-AMG.
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 metric horsepower (720 bhp (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 rating 0–62 miles per hour (0–100 km/h) 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.
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).
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.
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.
Pagani has made several special edition Huayras.
La Monza Lisa
The first special edition Huayra is called "La Monza Lisa". 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.
Pagani's second special edition Huayra is called "730S" and was ordered by Mexican supercar enthusiast Alejandro Salomon. In early 2016 Salomon put his Huayra up for sale, and it was purchased by David Lee, who is a notable Ferrari collector in California. Lee now calls the car "Da Vinci" but the car still has a plaque calling it the 730S. 
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 789 brake horsepower (588 kW) as well as 811 lb⋅ft (1100 Nm) 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% lighter than double-clutch gearboxes.
Pagani Huayra Roadster
On February 11, 2015 Pagani confirmed to GTspirit that a roadster version will be unveiled at the Geneva Motor Show 2016. Autoblog later reported that Pagani had decided to unveil the Huayra BC instead, and the roadster would debut later in the year. The Pagani Huayra Roadster will run on a 6-litre twin-turbocharged V12 Mercedes-Benz AMG engine.
