2017 PAGANI Huayra BC – Hyperlight Aero + Xtrac Race Drivetrain for Street-Legal Masterpiece

Huayra BCWelcome to the hottest new Pagani!

The BC is named after Horacio’s very first customer, Benny Caiola, and is a hell of a tribute indeed.

Every body panel except the roof is all new for this track-ready beast of a machine.  Power is up, weight is radically down, and a new active diff and Xtrac racing paddle-shifter will drop laptimes down radically as well.

And one of its best details?  One that will send your happiness quotient through the clouds?!

Unlike the Pagani Zonda R or Zonda Revolucione, the Huayra BC will be fully street-legal worldwide.  Yes, this includes the US market.

Pagani has graciously provided a very detailed 70-photo pack along with the initial tech details and ballpark performance numbers for its freakishly-focused new flagship.  We will consciously try to use fewer exclamation points than a car like this demands…. purely as a service to you, dear reader. =]2017-Pagani-Huayra-BC---Exterior-Photos--622017 Pagani Huayra BC - Exterior Photos 63 2017 Pagani Huayra BC - Exterior Photos 37


The design of any Pagani has always been led by aero, performance and strength metrics more than classical beauty.  Where other supercars hide their nitty gritty details like screw-heads, Pagani made his own titanium-alloy nuts and bolts. Strong enough for NASA, but beautiful enough for MoMA — has been the divine purpose of all his machines.

Over time, the auto world has come to respect — at very least — the raw aesthetic Pagani is unique in delivering.  For a select group of about 110 (total!) owners of any Pagani in the last 15 years, the complete sensory immersion — tacticility and full, heart-stopping sight sound and motion — the man is revered as a God-like engineer among mere mortals.

In that vane, the Huayra BC is a return to form.  Beauty and first-impressions are not nearly as important as raw functionality.

That certainly applies to the Huayra BC — as its first-look Facebook comments can attest.  People hate its looks.

But you know what?  Online commenters suck.  And are rarely, if ever, right — despite their blunt insistence to the contrary.  F*** ’em.  They will never appreciate great fine art, either.

We have a finer appreciation for the detailed, highly labor-intensive makeover the Huayra Coupe needed to become as focused, fast and record-setting as the previous Zonda R and Revo track models.

In short, this is a serious car for serious drivers.  Who will — in all seriousness — never experience a more thrilling way to part with $3-million.2017 Pagani Huayra BC - Exterior Photos 21 2017 Pagani Huayra BC - Exterior Photos 25


The design of the BC is all-new and controversial largely thanks to its insane aero revamp.  The quad active wings (two in front, two in back) still do their G-force dance to keep the car sucked into the pavement even in rapid transitions.

And the underbody is still smooth as glass.

But where the Huayra took a smoother approach to its intakes, outlets and air ducts — the BC makes them all 4X more powerful.  It starts with a long-nose point in the leading edge of the BC’s grille.  And below there, an all-new lower splitter and chin spats just centimeters off the tarmac.

Integrated planes extend from the new-look LED DRLs and out into an upward arc. 2017 Pagani Huayra BC - Exterior Photos 27 2017 Pagani Huayra BC - Exterior Photos 24

The real action continues up the fenders: new integrated slices free trapped heat from the wheel-wells out the top of the car’s wings.  Behind the front axle, new slices and carved-out elements shoot air from the underbody and away from the car — enhancing downforce radically.

New scoops ahead of the rear axle funnel the needed air to the new active diff in back and Xtrac transaxle.

A new airfoil just behind the doors is functionally needed to maximize the aero of the tailwing — a giant fixed element that looks LMP1-strong, yet also quite beautiful.

Square rear fender exits live in the upper rear flanks, while a full-width — and very tall — rear diffuser again creates mini-vortices of rapid air.  This lightens the vehicle and creates a ground-effect suction onto the pavement. How?  The air pressure under the car can be marginally lighter than normal — again creating a ground-effect level of intense downforce.

Like the Pagani ZOnda R and Revo previously, the BC is honed for track attack laptimes.  One track in particular: the Nurburgring.  This 12.9-mile green hell is where the R and Revo shocked the world with 918, P1 and LaFerrari-beating pace.  And deeply embarrasses any Aventador, including the new SV.

But those records were hard to tout, as the cars were not road legal.

The BC makes all those astrices irrelevant: the BC is road legal and a production car.  This will make its eventual pace around the Green Hell stand the test of time on fastest-lap boards of the world’s hypercar elite.

The near-singular laptime focus of the BC upgrade let the engineers go wild with downforce aero — sans any concerns that it will slow down the ultimate speeds possible.  A radically lightened suspension uses a new forged alloy to cut weight nearly in half.  The new active diff, variable race ESP settings, and Xtrac gearbox are all finely honed to this purpose, versus overall top speeds, for example.   Gear ratios and power are also fit for purpose — with a pre-sale estimate of 750HP-plus from a recently-tweaked AMG V12TT.

Fit to be the fastest, most intoxicating supercar of all time — right down to its bespoke nuts and bolts.

Huayra roars….

God of Wind, indeed!

2017 Pagani Huayra BC


The Pagani huayra BC

Pagani over the years. Benny was so impressed by the passion and technology of the cars Horacio was designing from the very beginning, he made history as the first customer to buy a Pagani Automobile.he name “BC” represents the initials of Benny Caiola, a person who has greatly inspired Horacio 

The Huayra BC is the most technologically advanced Huayra Coupé yet, introducing innovative technical solutions which will be applied in the Pagani cars of the future. This not just a “restyling” of the Huayra, but a product that includes innovative changes in every part of the vehicle. It’s a car that has a completely different personality to that of the Huayra Coupé.

Conceived primarily as road going car that will give the maximum exhilaration and performance during track days and special events, the Huayra BC has been inspired by its “track focused” predecessors: the Pagani Zonda R and the Zonda Cinque.

In recent years we have been presented with products that have delivered a new direction for the supercar, introducing hybrid propulsion, a combination of combustion engine and electric motor.

After much careful consideration and research, Pagani Automobili decided not to go the route that others have followed and chosen instead to focus efforts on other technological areas of development that aimed to:

  • Create the lightest, globally homologated, Hypercar
  • Develop chassis and suspension systems that are derived from motorsport to deliver dynamic and secure car, fast and fun, that retains the comfort typical of a Pagani.
  • Develop a completely new AMT (Automated Manual Transmission) paying particular attention to both the performance and comfort, without compromising the weight and balance of the car.


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.


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.


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 evaluation, 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 specification 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.


The Bosch ESP system has been specially calibrated to make the most of the newly developed components and in addition to the familiar driving modes of “Comfort” and “Sport”, a third mode has been added for track use, suitably called “Track”. The modern generation of traction control systems, allow you to optimize performance, and maximize the available traction, assisting even the most experienced drivers, without hindering the driver involvement or enjoyment.


Underpinning the design of the Huayra Coupé was concentration to maximize the aerodynamic efficiency in terms of resistance to attrition and the cancelling out the effect of “lift” on the vehicle body, incorporating for the first time in the history of supercars, active aerodynamics.

The philosophy behind the Huayra BC sought to bring this concept to extremes in the pursuit of aerodynamic performance by increasing downforce even further. During the birth of the Zonda, Horacio Pagani worked in the wind tunnel together with Gian Paolo Dallara, founder of Dallara Automobili and was a great inspiration and mentor to the young Horacio. For the Huayra BC, Horacio and his team have worked extensively on the aerodynamic properties of the car. The many months of study and CFD simulations have defined a form that generates maximum downforce for a performance car like the Huayra BC whilst retaining the unmistakable design language of Pagani.
