Pagani Huayra BC at Miller Motorcars – Video
Immediately you can notice the Pagani Huayra BC is louder than the standard Huayra with the new exhaust system on the car along with the upgraded engine. Even when it’s revving the crackle and popping from the exhaust seems to be even more intense.
Pagani Huayra BC Specs:
Engine
The Huayra BC is powered by a V12 Bi-Turbo engine developed by Mercedes AMG exclusively for Pagani. The engine unleashes more than 750 horsepower, and is approved CARB and EU6.
The sports exhaust includes a low back pressure muffler and is substantially lighter compared to the system used on the Huayra coupe. The result of careful acoustic design in geometries and materials such as titanium, the sound of the car with the sports exhaust system becomes even more intense and exciting delivering a truly unique experience when driving the Pagani Huayra BC on track.
Transmission
The Huayra BC features a 7-speed AMT (Automated Manual Transmission) developed from scratch and represents a new benchmark in this transmission technology. The gearbox, developed and manufactured by Xtrac, features a new electro-hydraulic actuation system and new carbon fibre synchronizers, designed to increase the precision of gear engagement and further reduce gearshift times. The clutch control program has also been heavily revised, allowing greater accuracy, despite the increased torque of the engine.
A brand new electronic active differential has been introduced to the platform. The advanced electronic differential control allows the differential to adapt to a full range of demanding driving conditions, from low grip situations, to the extreme driving performance required on the track, always maximizing the traction and increasing the stability of the vehicle. The result is a highly rewarding and dynamic experience that always inspires confidence.
The weight of the gearbox, including the electronic differential, is approximately 40% lower compared to that of a dual clutch transmission of the present generation. The transverse layout contributes towards the compact packaging and focuses the mass towards the vehicles’ centre of gravity. The net result is that it reduces the polar moment of inertia which has a negative effect on the stability and can create a tendency to oversteer.
To complete enhancements to the transmission package, there are all new tripod axle drive shafts, derived from the world of Le Mans racing. No drive shaft system used on other road cars can guarantee the same efficiencies in the transference of the power through the drivetrain compared to the solution now adopted by Pagani and this represents a significant step in introducing this pinnacle of drivetrain technology to a road car platform.
Suspension
The specially developed, bespoke suspension system of the Huayra BC, is the lightest and most effective ever applied to a road going hi-performance vehicle. The suspension components themselves are forged from HiForg, a lightweight aeronautic aluminium alloy of exceptionally high strength. Continuous eva- luation, calculations and testing have allowed us to optimize the design to achieve a weight saving of 25% compared to the suspension of the Huayra Coupe. Even the uprights have been completely redesigned, reducing the weight and increasing the rigidity of the components. This translates into a noticeable increase in the dynamic capabilities of the car, being even more responsive and reactive than before.
Braking System
Brembo is a long standing partner of Pagani Automobili and for the Huayra BC they have developed a dedicated CCM (carbon-ceramic) braking system, with a design that integrates seamlessly and is able to withstand the additional demands that are a result of the increased performance of the vehicle. The callipers are made with a new proprietary manufacturing technology developed by Brembo, through which their engineers have managed to significantly reduce unsprung weight. The calliper is also stiffer thus allowing increased stability in performance under repetitive high performance braking scenarios which is critical to the design requirements of a Pagani.
Wheels & Tyres
Like all Pagani models, the Huayra BC will be exclusively equipped with Pirelli tyres. Specifically, the car will run on P Zero Corsa in 255/30ZR20 and 355/25ZR21 sizes, guaranteeing the new hypercar from Modena high levels of safety in all usage conditions. The latest P Zero Corsa has a more aggressive-looking asymmetric tread pattern, with three longitudinal grooves reminiscent of the Formula One slick tyres from a few years ago. Another link with Formula One exists in the tyre’s geometry and the structure of the bead, which has been designed to absorb the intense stress and flexing generated by a car that puts out more than 1000 horsepower. Pirelli’s engineers have created a bespoke product for the Huayra BC that uses new polymers of high molecular weight, improving grip. New mixing systems also mean that the distribution of materials is optimised. Finally, a new structure has reduced the weight of the tyre by around 3%. The lightweight, functionally focused, forged wheels are sized 20 inches on the front axle and 21 inches on the rear axle. In a track optimised speci cation the Huayra BC can be equipped with the Pirelli P Zero Trofeo R on dedicated 19 inch front wheels and 20 inch rear wheels. These tyres have been developed for track use only and help the vehicle to achieve staggering lateral accelerations with peaks of 2G.
