Pagani says the Huayra will be sold in the U.S. in 2013

As you may know already, NHTSA said yesterday that the $1.1 million Pagani Huayra supercar can’t be sold to the U.S. due to the fact that the vehicle doesn’t have advanced airbags. It appears that this decision was quite annoying for Horacio Pagani, founder of the Pagani company, who decided to explain the situation. According to the official Pagani letter brought by GTSpirit, Horacio said that his company created a safe supercar.

According to the press release, the Pagani Huayra features center tub in carbo-titanium, as well as an intelligent fuel system that behaves in a precise fashion during a crash. Moreover, a significant investment was made when the company was studying how the subframes would behave in a side crash, especially the rear subframe.

According to the manufacturer, the car detaches from the carbon safety cell, dissipating kinetic energy by getting rid of over 400kg of the weight to which the occupants are attached at that moment.

What is really interesting is that Pagani said that the integration of advanced airbags are in its plans and that the airbag components found on the Huayra are already compatible with advanced airbag management (airbag, advanced belt retainer, steering column).

Moreover, cars such as Bugatti, Lamborghini, Ferrari, Koenigsegg and Spyker don’t feature advanced airbags, and are already on U.S. streets, so why not give Huayra a chance? Regarding he debut on the U.S. roads, it appears that the Pagani Huayra will start deliveries in early 2013.

“Friday the 29th of July, we received from NHTSA the denial of our petition (Five days prior to our first US event and about three years after it was requested). This news spread like wildfire. Fortunately, however, over the last months, after having not heard anything from the authorities, we sped up the development of the advanced system with a large number of simulation runs and tests.” said the official letter.

The Pagani Huayra follows the aerodynamic concept of the wing. You can change the aerodynamic properties of the car by changing the front ride height and by adjusting the control flaps that you find at the corners of the car. The aim is to give you a smoother ride under all road and weather conditions, and control the car using the aerodynamic features.

There is a dedicated control unit that controls the flaps. These control units get information from the ECU and the ABS, such as the steering angle, yaw rate, speed, throttle position, and lateral acceleration.

Daily driving and other driving conditions do not rely on low drag coefficient all the time and this is where the system helps. When you apply the brakes, for instance, the front suspension and the rear flaps are raised to help balance the weight distribution and counteract the weight transfer between the rear and front axles.

Another important design aspect for the Huayra is the clean airflow over the car’s body. The two engine air intakes that you see here are reminiscent of the supersonic aircraft that you see during the 1950s and 1960s. It allows the motor to breathe without disturbing the airflow.

The intake for the gearbox radiator

Between the carbon clamshell and the engine bay window of the rear bonnet, you will find the gearbox radiator intake that gives outstanding airflow to the radiator without affecting the aerodynamic drag. This is also why instead of a rear wing, you have movable flaps.

The car’s airflow was thoroughly studied, and the radiators were angled for added downforce and better exhaust. Air coming from the central radiator is let out by vents found on the trough of the front wheelhouses and the vents you find on the front bonnet. Similarly, air coming from the side radiators is extracted via ducts that help cool the wheel hubs and the brake discs. This air blows on the brakes at around 50 degrees Celsius effectively heating the brakes up during cold weather, and you get a better first bite. Behind the front wheels, you have lateral air outlets that help lower the drag to give you more downforce.

Complementing the downforce created by the body and the flaps, you also have a pair of high negative pressure areas that follow the shape of the underbody as well as the diffuser at the back, giving you more aerodynamic stability while also giving you more downforce no matter what the circumstances.
