Pagani introduces Huayra BC


E1---Pagani-Huayra-BC-320160308More powerful model includes lighter components, bespoke gearbox

Pagani has unveiled a more powerful version of its Huayra hypercar called the Huayra BC. The Italian supercar maker said in a statement the model is named after the late property magnate Benny Caiola, who is a close friend of company founder Horacio Pagani and the first person to buy a Pagani super car. The company also said the Huayra BC was inspired by its track-oriented predecessors: the Zonda R and the Zonda Cinque.

30-HP increase, all-new gearbox
Like the standard Huayra, the Huayra BC is powered by a twin-turbocharged, 6.0-liter, single-cam, 36-valve, direct-injection, Mercedes-AMG V12 engine. But this version gets an additional 30 horsepower for a total of 750 horsepower, aided by a lighter titanium sports exhaust system that includes a low back-pressure muffler.

In addition, the punchier powerplant has been mated to an XTrac seven-speed automated manual transmission or AMT designed for the Huayra BC – some 40 percent lighter than the standard Huayra’s transmission – that features a new electro-hydraulic actuation system and new carbon-fiber synchronizers that are designed to increase the precision of gear engagement and further reduce gearshift times. The clutch-control program has also been heavily revised for greater accuracy, despite the increased engine torque.

The transmission is mated to a new, electronic, active rear differential that the company said can adapt to a full range of demanding driving conditions from low-grip situations to the extreme driving performance required on the track. Completing the drive train are all-new, tripod-axle driveshafts, which the company said is derived from the world of Le Mans endurance racing.

Lightweight suspension, carbon-ceramic brakes
To handle the extra power, the company said the Huayra BC has a specially developed, bespoke suspension system forged from HiForg, a lightweight, aeronautic aluminum alloy of exceptionally high strength, which makes the system 25-percent lighter than the standard Huayra suspension. Further lessening weight are the completely redesigned suspension uprights.

Attached to the suspension are lightweight, forged wheels, wrapped in Pirelli P Zero Corsa tires, which are 20 inches in front and 21 inches at the back. The optional track-optimized specification gives the Huayra BC 19-inch front wheels and 20-inch rear wheels with Pirelli P Zero Trofeo R tires, which the company said have been developed for track use only and help the vehicle to achieve lateral accelerations of up to 2g.

Hiding behind either wheel option is a Brembo carbon-ceramic braking system made exclusively for the Huayra BC that the company said is able to withstand the additional demands of the increased performance of the vehicle. The six-piston front and four-piston rear calipers have been made lighter and stiffer, thus allowing increased stability in performance under repetitive high-performance braking scenarios.

Revised esp, new aerodynamics
Working in tandem with the brakes is a specially calibrated Bosch Electronic Stability Program or ESP that the company said comes with the familiar Comfort and Sport driving modes. For the Huayra BC, a third mode has been added for track use, called Track.

Meanwhile, the company said the Huayra BC’s exterior has been completely redesigned, sharing only the roof with the standard Huayra. Notable changes include a deeper front splitter with winglets, a revised side skirt, a wider rear lower diffuser and a fixed rear wing in lieu of the active rear spoiler in the regular Huayra.
