Pagani Huayra

The Pagani Huayra is a mid-engine sports car produced by Italian sports car manufacturer Pagani, superseding the company's previous offering, the Zonda. It is named after Wayra Tata, the Quechua (indigenous South American) wind god. The Huayra was named "The Hypercar of the Year 2012" by Top Gear magazine. On 11 February 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 Pagani Huayra was officially debuted online with several pictures in a press release on 25 January 2011. The official world debut was at the headquarters of Pirelli in Milan in February 2011.

Specifications
The Huayra has a top speed of about 238 mph and it has a 0-60 mph acceleration time of 2.8 seconds. Using Pirelli tyres, the Pagani Huayra is capable of 1.66 g of lateral acceleration.

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

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 in diameter and 34 mm thick.

The Huayra uses a 5980 cc twin-turbocharged M158 60° V12 engine developed by Mercedes-AMG specially for the Huayra, which has a power output of 740 PS at 5,800 rpm and 1000 Nm of torque at 2,250-4,500 rpm. The engine has been designed at the request of Pagani to reduce turbo lag and improve response, achieved with smaller turbochargers, 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 mpgus in city and 14 mpgus 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 minimise 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.

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 counter-act 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.

BC
The Huayra BC is a track focused version of the Huayra which was unveiled at the 2016 Geneva Motor Show. 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 L twin-turbocharged V12 engine having a power output of 764 PS at 5900 rpm as well as 1000 Nm at 2500-5600 rpm of torque. The dry weight is reduced by 132 kg to just 1218 kg, thanks to the use of a new material called 'carbon triax' which Pagani claims is 50% lighter and 20% stronger than regular carbon fibre, giving the car a power-to-weight ratio of undefined kg per horsepower. The Huayra BC comes 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 front splitter and winglets, deeper side skirts, and an air diffuser that stretches the entire width of the rear bumper with a large rear wing. The car could be ordered with an optional roof scoop. All of the exterior components in the car are used to optimize downforce and drag. The Huayra BC uses an Xtrac 7-speed sequential manual transmission. Pagani has stuck with a single-clutch gearbox because it weighs 40% less than double-clutch gearboxes.

Pagani planned to make 20 units of the Huayra BC, which were all sold out. In reality, Pagani drastically overproduced the Huayra BC, producing 30 units instead of the promised 20, to the irritation of some owners.

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

The over-all appearance of the car has changed, with the most obvious being the removable top (hence the Roadster name). This part of the vehicle is also its key element. The design of the rear is also different, with new eyelid-like fixed flaps that continue with the design and eventually end on the rear lights. The rear engine cover also has a new shape to adapt to the roadster form and now has vents for efficient cooling. The wheels are unique and specifically constructed for the car. The car has conventional doors instead of the Gull-wing doors of the coupé as they are impossible to fit on an open top car while maintaining the low weight.

The vehicle utilises the same twin-turbocharged M158 V12 engine as the coupé, but it now has a total power output of 764 PS at 6,200 rpm and 1000 Nm of torque at 2,400 rpm. All of this power is delivered to the rear wheels via a 7-speed automated manual transmission by Xtrac. The car now uses a hydraulic and electronic activation system with carbon synchronizers. Bosch has also contributed in the construction of the car and the car uses their ECU system. The weight is now 70 kg lighter, for a total of 1,280 kg, making it the first roadster lighter than the coupe version. Only 100 will be made, all of which have already been sold. The tyre supplier is Pirelli, with P-Zero tyres. The tyre have a white narrow outline, resembling those of an F1 race car. Pagani has also used a new material for the Roadster called carbon triax, which is a tri-axis fiberglass meshed with carbon-fibre power bands.

Pagani states that the car produces 1800 lbs of downforce or 1.8 lateral G-force. However, this figure is unproven, but if true, Pagani will have set a new record.

Roadster BC
Introduced in July 2019, the Huayra Roadster BC, often mistakenly called the Huayra BC Roadster, is the track-oriented version of the Roadster. It shares few aerodynamic parts as present on the BC and has a modified version of the 6.0-litre twin-turbocharged V12 engine rated at 802 PS and 774.5 lbft of torque. The 7-speed Xtrac sequential gearbox with single clutch used on the roadster is 35% lighter than a contemporary dual-clutch gearbox. The Huayra Roadster BC sits at 1250 kg which is slightly heavier than the coupe, with a dry weight of 1218 kg. It is 66 lb lighter than the Huayra Roadster 1280 kg. The monocoque of the Roadster BC is constructed of carbon-titanium HP62 material to keep weight low and make the construction rigid. The Roadster BC is claimed to generate 1102 lb of downforce at 174 mph due to its large fixed rear wing and aerodynamic elements. In addition to movable active Aero elements, the titanium exhaust incorporates flaps in the catalytic converters to divert exhaust gases over the underfloor elements like a Formula 1 car's blown diffuser. Production of the Huayra Roadster BC will be limited to 40 units only.

Imola
Introduced in February 2020, the Imola is named after the Autodromo Internazionale Enzo e Dino Ferrari (Imola Circuit), where it underwent 16,000km of high-speed testing. It is the most powerful street-legal variant of the Huayra, using the same Mercedes-AMG V12 tuned to 838 PS and 1100 Nm. Weight saving measures such as a new carbon fibre blend and lightweight paint application have reduced the Imola's dry weight to 2747 lb. Exterior changes from the standard Huayra include a large seven-section diffuser, a large roof scoop, a shark fin, more pronounced side skirts and a wide fixed rear wing with an integrated stoplight. Six Imola were built: 5 for customers and 1 prototype for Horacio Pagani.

Tricolore
On December 16, 2020, Pagani introduced the Huayra Tricolore, was built to celebrate the 60th Anniversary of Frecce Tricolori, Italy's aerobatic team. The Tricolore uses a twin-turbo 6.0-liter V12 engine sourced from Mercedes-AMG which has been tuned to produce 829 horsepower and 811 pound-feet of torque, which is 38bhp and 37lb ft more than the power and torque produced by a standard Huayra BC engine. The car is only available in roadster form and shares much of the bodywork of the Roadster BC. It is unpainted except for a clear blue lacquer, and red, white, and green stripes from the nose along the top of the car's surface. Inside, the Tricolore is equipped with white and blue leather seats with Italian flag stripes, and the Tricolori logo is embroidered into the headrests. The Pitot tube mounted on the nose of the car, a metal measuring device that's typically uses on planes to measure air speed, is a unique feature of the Tricolore.

The production is limited to three customer units as its predecessor and priced at €5,500,000+taxes ($6.7 Million+taxes) each. In reality, there will be four Huayra Tricolore: 3 customer cars and 1 prototype owned by the company. The first two customer cars have been delivered, as of early 2022. One car went to a customer in Stuttgart, Germany, while another went to a customer in Wisconsin, USA (but delivered through Pagani of Dallas).

R
In March 2021, Pagani introduced the Huayra R, a track-only version of the Huayra and the successor of the Pagani Zonda R. The Huayra R uses the "Pagani V12-R", a version of the 6.0 L naturally aspirated Mercedes-Benz V12 engine built from the ground up by HWA AG to produce 850 PS at 8,250 rpm as well as 750 Nm of torque at 5,500 rpm to 8300 rpm, and a redline at 9,000 rpm. The Huayra R has a 6-speed sequential transmission newly developed for the car, and various weight saving measures have resulted in a lower dry weight of 1,050 kg.

Pagani plans a limited 30-car production run for the Huayra R, similar to the limited 15-car production run of the track-only version of the Pagani Zonda, the Zonda R. It will cost €2.6mln + taxes (around $3.1mln + taxes).

Codalunga
On June 16, 2022, Pagani introduced the Huayra Codalunga, a 5 units limited version of the Huayra, to pay homage to the lines of racecars from the 1960s, like the Porsche 917 (Horacio's favorite car). Prices started at €7mln+tax (around $7.36mln+tax) with all 5 units being sold before its unveiling. This car was the result of a special project by Pagani Grandi Complicazioni.

Imola Roadster
On November 23, 2023, Pagani introduced the Imola Roadster, the convertible version of the Pagani Imola but inspired by the Huayra R.

The Imola Roadster uses the same Mercedes-AMG V12, 6.0-liter twin-turbo engine to produce 850 PS (625 kW; 838 hp) at 5,600 rpm as well as 1,100 N⋅m (553 lbf⋅ft) of torque from 3,600 to 5,600 rpm.

Production of the Imola Roadster will be limited to 8 units only.

Lampo
In December 2017, Pagani introduced the Huayra Lampo in partnership with Lapo Elkann of Garage Italia Customs. The car is inspired by the Fiat Turbina concept introduced in 1954. This particular Huayra gets the ‘Tempesta’ pack too: larger front openings, plus new aero elements on the front splitter and sills.

Epitome
In July 2024, Pagani introduced a one-off version of the Huayra called the Huayra Epitome, which was developed by Pagani Grandi Complicazioni. It is powered by a twin-turbocharged 6.0-liter V-12 engine sourced from Mercedes-AMG that develops 852 horsepower and 811 pound-feet of torque, and revs to 6,700 rpm mated to a seven-speed manual transmission.
