Pagani Huayra
Ancient legends of the Aymara tell us of Huayra Tata, god of wind, who commands the breezes,
winds, and blizzards that invade the mountains, cliffs and hills of the Andean highlands. It is
told that Huayra Tata resides deep in the high peaks and valleys, abandoning them only to
demonstrate his power to his wife, Pachamama, goddess of mother earth. With his power
Huayra Tata was able to lift the waters from lake Titicaca and rain them down on the fertile
Pachamama. When Huayra Tata sleeps, the waters and rivers lay quiet.
But the calm before the storm is about to be interrupted...
Design
The eternity of the element air. Gentle and refined, yet the strength of the wind it is able to
erode even the toughest of materials giving birth to distinctive shapes known in nature. Elegant
and muscular the Huayra merges the past, present and future in a timeless interpretation of
automotive art.
The styling of the car was perfected over the course of 5 years to find each line's beginning
and end. During this study, eight scale models were created, as well as two 1:1 models, each
an evolution of the previous in a never ending quest to perfect the form and refining the
substance.
The bi-xenon headlamps are just one of the many precious gifts from the Zonda R, and LED
daytime running lights are seamlessly integrated in the elliptical shape of the design. The rear
bumper integrates with the diffuser and is dominated by an elliptical frame that surrounds the
four central exhaust outlets, now becoming a characteristic Pagani element.
Backbone
The new central monocoque on the Huayra is an entirely new design made from carbon-
titanium. However, with the gull wing doors cutting deep into the roof, much research was
focused on achieving the highest levels of rigidity through the application of new advanced
composite materials and technologies first tested on the Zonda R. The fuel tank is located
integrally in the best protected area of the monocoque, behind the driver, reinforced by safety
cell made of different composite and ballistic materials. The front and rear CrMo subframes
offer an exceptional rigidity-to-weight ratio to allowing the suspensions to work at their best
while incorporating an advanced energy absorbing crash structure, ready to protect the occupants
in the unlikely event of an impact.
Heart
Mercedes-AMG provides the heart for the Huayra. The 60 degree 12 cylinder turbocharged
engine with a displacement of 5980 cm3 has been developed not just to meet the strictest
technical and quality requirements, but also to give the car its many faces.
The calm and harmony of driving one of the world's most refined GT car is interrupted when
the driver calls upon the Huayra to unleash its 700 horsepower and 1000 Nm of torque. The
turbos have been studied to offer immediate response to the slightest throttle input, giving
the driver full control over the engine at any rpm and preventing unwanted delays in the delivery
of power.
The engine's systems have been designed and tested to stand up to the most adverse conditions
of temperature and performance. The Huayra has been subjected to the highs of Death Valley
and the lows of the Arctic Circle. The two lateral radiators are positioned in the front to
guarantee the best cooling efficiency of the intercoolers placed over the cylinder heads. Dry
sump lubrication ensures an optimal oil feed to the engine even when the car is subjected to
the most extreme lateral accelerations. It also regulates the oil flow so that only the necessary
amount of lubricant is actually pumped into the engine from the external oil tank, reducing
the friction caused by an excessive volume of lubricant inside the engine sump. An oil/water
heat exchanger reduces warm-up times by heating the engine lubricant during cold start and
keeps engine coolant and lubricant levels at steady operational temperatures. Extensive weight
saving programs led to ingenious yet simple solutions. In order to reduce hoses and connections
as much as possible is built directly to the engine. The intercooler covers serve as expansion
tanks to the low temperature circuit and the engine coolant circuit. The vertical fins contribute
to the cooling of the tanks.
The M158 engine is homologated to meet the strictest environmental regulations, EU5 and
LEV2. Despite the increase of power compared to the other Mercedes-AMG V12 engines
developed for Pagani, C02 emissions as well as the fuel consumption have been reduced, to
make the Huayra class leading amongst 12 cylinder sports cars with values that are respective
of much smaller vehicles in the market. The two stage fuel supply system features two
microprocessor controlled pumps feeding fuel to the engine with the second pump only
activated when necessary, thus reducing the energy required to run the fuel pumps and
eliminates the waste of excessive fuel being transported and heated in the fuel lines. This
efficiency combined with a large 85 liter fuel tank ensure Huayra's grand touring ability.
