Pagani Huayra wears its blue coat at the 2013 Geneva Motor Show

The Pagani Huayra, the one million euro hypercar that replaces the Zonda, is on display at the 2013 Geneva Motor Show. During development, the Huayra was known as the C9. The Huayra, which means ‘god of wind’, is pronounced ‘Wirer’ with a heavy Spanish accent. Company boss Horacio Pagan said that developing the Pagani Huayra took seven years and that it offers a type of supercar that’s different from the Zonda.

The Huayra, which is powered by a bi-turbo 6.0-litre V12 engine, continues Pagani’s collaboration with Mercedes’ AMG department. Pagani will be selling two Huayra versions. The standard engine has an output of 700bhp and 664lb ft while the Sport version offers 730bhp and 811lb ft. 

This block is shared with Mercedes’ SL65 Black Series but Pagani has tasked AMG to diminish turbo lag and boost the throttle progression. This resulted in new heads, pistons, manifolds and turbos. Pagani has not released many details about the Huayra’s performance but so far, it claims to have reached a top speed of 230mph and to have accelerated from zero to 62mph in 3.3sec.

It is also equipped with a three-stage Bosch traction control system.  The Huayra comes with a mandatory seven-speed paddle-shift gearbox that’s produced for Pagani by UK race specialist XTRAC.

To lessen the drivetrain’s length, the gearbox is mounted transversely at the back of the engine. The Huayra is bigger than the Zonda and bears more safety equipment but its kerbweight has been maintained at 1350kg (dry). Coupled with the forced induction, the Huayra is homologated for the US. This marks the first time for a Pagani to have done so.

The new Pagani Huayra follows the aerodynamic concept of a wing. The Huayra is designed so that it could modify the attributes of the wing just by changing the front ride height and by adjusting the four control flaps on each corners of the supercar. This way, the new Huayra will have a neutral vehicle behavior in any condition while enabling the driver to control body roll through aerodynamic manner. These flaps – their behavior in particular – are controlled by a dedicated unit, which receives information regarding the car's speed, lateral acceleration, yaw rate, throttle position and even steering angle.

Thanks to this system, the supercar’s aerodynamic efficiency has been enhanced in a number of driving conditions, especially when a low drag coefficient isn’t considered a vital element. For instance, the rear flaps and the front suspension are raised during braking to offset the weight transfer as well as to balance the weight distribution between front and rear axles. This way, the supercar could better employ the rear brake force.

In designing the new Huayra, Pagani aimed to ensure clean airflow over its body. While the shape of the two engine air intakes located behind the shoulders of the occupant pays homage to the supersonic aircraft of the late 1950s and 1960s, they also allow the motor to breathe without upsetting airflow. Meanwhile, the intake for the gearbox radiator has been placed between the rear bonnet’s carbon clamshell and the engine bay window – thereby providing outstanding airflow to the radiator without affecting the Huayra’s aerodynamic drag. Because of this, Pagani decided to replace the rear wing with movable flaps.
