The all-new monocoque central Huayra is built in carbon-titanium, with its gull-wing doors that include a good portion of the roof. The research focused on the application of advanced composite materials and technologies first tested on the Zonda R, to achieve the highest levels of rigidity combined with maximum lightness.
The constant quest for weight reduction has led to an ingenious combination of aesthetic, structural and otherwise. One example comes from the pipes of the cooling and air conditioning: the ambitious choice of integrating them into the monocoque structure has rendered superfluous the inclusion of additional components. The result of the reduction program is summed up in a vehicle weight of 1350 kg which makes lighter Huayra the supercar segment.
Mercedes-AMG provides the heart of Huayra. The 12-cylinder biturbo engine with 60 ┬░ V? with 5980 cm3 has been developed to meet not only the technical application and the strictest quality aspects, but also to give the car its dual character. The calm and harmony that are perceived to drive one of GT's finest today are interrupted when the pilot called Huayra to unleash its power over 700 hp and a torque of over 1000 Nm.
The turbines are designed to offer an immediate response to the minimum stress of the butterfly, giving the driver complete control over the power at any speed and preventing unwanted delays in disbursement. The two radiators on the sides of the mouth anterior ensure the best cooling efficiency of the intercooler located above the cylinder head. This cooling system at low temperature is designed to operate in adverse conditions of Death Valley with temperatures above 50 ┬░ C.
The dry sump lubrication also feeds the engine when the car is subject to extreme lateral accelerations. Also regulates the oil flow so that only the required quantity of lubricant is pumped into the engine from the external tank, reducing the friction caused by an excessive volume of fluid inside the base. The dry-sump oil pan makes obsolete the conventional one, allowing you to mount the engine and have a lower center of gravity away from less land.
A heat exchanger oil / water reduces engine warm during cold start and keeps the refrigerant and lubricant temperatures stable. Extensive weight reduction programs have resulted in simple yet ingenious solutions. In order to limit as much as possible to pipe connections and the expansion tank is mounted directly on the engine.
Bulkheads intercooler act as reservoirs of the expansion of low-temperature circuit and the engine coolant circuit. The M158 engine is certified to the strictest environmental regulations and EU5 LEV2 and, despite a significant increase in power compared to engine developed by Mercedes-AMG in the past for Pagani, fuel consumption and thus CO2 emissions have been killed so that Huayra holds the record among female athletes to 12 cylinders, with values close to cars on the market of displacements and lower powers.
The large 85-liter tank ensures a longer range travel. The power system in two stages with no return has two power pumps that send fuel to the engine by activating the second pump when needed. To further increase the demand for fuel efficiency is controlled by a microprocessor on each pump, releasing the required amount from the engine control at any particular time.
This reduces the energy needed to operate the fuel pump and eliminates the waste of excessive fuel transport and heating ducts of gasoline. As a tribute to the decade-old tradition of Mercedes-AMG to build engines in the world for sports cars, the M158 boasts the historic AMG emblem on the intake manifold along with the name of the technician cha has hand-assembled at the headquarters Mercedes-AMG Affalterbach to Germany.
The titanium exhaust system has been engineered by MHG-Fahrzeugtechnik and is a direct application of technologies racing on a high-performance road car. The hydroformed junctions have been developed to reduce the pressure and ensure a free flow of exhaust gases. Titanium offers a limited role in the silencer while offering reliability Iconel exhaust parts most exposed to high temperatures.
The full exhaust system weighs less than 10 kg and research undertaken to ensure maximum pleasure sound translates into a harmonious and deep roar that portends a wave of power ready to erupt with a roar, accompanied by the hiss generated by aircraft intakes' air.
Think Huayra as a wing, able to actively change its angle of attack by changing the height of the front from the ground and operating independently of the four flaps placed at its ends. The result is that the machine constantly change its shape, from time to time to ensure the minimum friction coefficient and the maximum downforce.
The car fully respects the most exacting standards of Europe and the United States in terms of safety and environment. In addition, specific research has been conducted to study the dynamics most often involving this type of car accident. Several cars were used to validate these tests. The survey showed that the evaluations have led us to apply concepts of construction not specifically required by law but how to improve occupant protection.
