Pagani Huayra 2011

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.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.

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 aerodynamic concept of the Huayra is that of a wing. The vehicle can modify the properties of this wing by varying the front ride height, which can be adjusted dynamically, and by adjusting the 4 control flaps on each of the four corners of the car. The goal is to have a neutral vehicle behavior under all conditions and control body roll via aerodynamic means. The behavior of the flaps is managed by a dedicated control unit that is fed information from the ABS and ECU, which pass information about the car’s speed, yaw rate, lateral acceleration, steering angle and throttle position.
The system improves aerodynamic efficiency in a variety of driving conditions, where a low drag coefficient is not the determining factor. During braking, for example, the rear flaps and the front suspension are raised to counteract the weight transfer and balance the weight distribution between front and rear axles, allowing a better use of the rear brake force.

Another vital design tenant for the Huayra project was to ensure clean airflow over the body of the car. The shape of the two engine air intakes behind the occupants shoulders are a tribute to the supersonic aircraft of the late 1950s and 1960s, but also allow the motor breath without disrupting the flow. The intake for the gearbox radiator is located between the engine bay window and the carbon clamshell of the rear bonnet, which provides an excellent airflow to the radiator without having a substantial impact on aerodynamic drag. This decision also led to the omission of a rear wing, replaced by the movable flaps.

In addition to the downforce generated by the flaps and body, two high negative pressure areas were designed into the shape of the underbody and the diffuser at the rear, thus enhancing the aerodynamic stability and guaranteeing the Huayra downforce under all circumstances.
