The Pagani Huayra BC has already made its global debut some time ago. However, that won’t stop the carmaker from releasing this utterly cool “making of” video of the one-off supercar while it underwent testing in extreme cold weather conditions.

In the two-minute video, the Huayra BC is seen with its unique “QR code” prototype camo as it is guided carefully on the slippery, snowy surface. Of course, this isn’t made easy by the fact that the Huayra BC is rear-wheel drive by default, and you’ll get to see some sideways motion as a result.

Fitted to the Huayra BC is a new electronic active differential that allows the car to better adapt to a full range of driving conditions, from low grip situations, to the driving performance required on the track. We’re guessing the snowy conditions seen here is test out the former.

Of course, a new differential isn’t the only change here. Pagani is adamant that the BC is “a product that includes innovative changes in every part of the vehicle.” Therefore, the 6.0 litre biturbo V12 gets bumped up to 750 hp, and a lightweight seven-speed AMT gearbox with new tripod axle drive shafts derived from the world of Le Mans racing are also fitted.

Under the metal (or carbon fibre), the car’s suspension system has its components forged from HiForg, a lightweight aeronautic aluminium alloy. Improvements elsewhere include a Brembo-developed carbon ceramic braking system as well as new aerodynamic bits. Pagani also worked with Bosch on improving the car’s ESP and ABS systems.

The Huayra BC was made as a tribute to Benny Caiola, the company’s first-ever customer, and close friend/mentor to Horatio Pagani. Only 20 units of the hardcore Huayra will be made, and it’s too late for you to get one even if you have the 2.3 million euro (RM10,597,782) asking price, as all were sold long before it was even revealed.
