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
carbontitanium. 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.The never ending quest for weight reduction resulted also into
the combination of structural and non-structural or aesthetical
elements. An example is the integration of all ventilation air ducts
into the monocoque’s structure, making the use of additional parts and
ducts unnecessary. The result of this attention to detail is a vehicle
weighing 1.350 kg making the Huayra the lightest sportscar in its class.
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, CO2 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.As an homage to the decennial tradition of
Mercedes-AMG in building world class sports car engines, the M158
displays the historic AMG emblem on the intake manifold alongside the
name of the technician that assembled the engine by hand at the
Mercedes-AMG headquarters in Affalterbach, Germany
