764HP Pagani Huayra Roadster Twin Turbo V12
One of the ambitious goals set at the beginning of the project was to build a Roadster that would be lighter than the Coupe, improving the torsional rigidity of the frame. Armed with the expertise gained from the Zonda R, Huayra Coupe and the Huayra BC, the Pagani engineering team further refined the development of carbo-titanium. Combined with a new form of composite material and developed for the Huayra Roadster, it is considered more advanced than materials used for Formula 1 cars. This complex and highly ambitious undertaking has allowed for a 52% increase in stiffness, at the same weight, thanks to the combination of the Carbo-Titanium and the Carbo-Triax HP52. The dry weight of the Huayra Roadster measures 1,280kg, about 80kg less than the Huayra Coupe, while also increasing in torsional flexional rigidity – an incredible achievement by its own right, from a purely technical standpoint.
The Pagani Huayra Roadster is powered by the Mercedes-AMG M158 engine. The twelve-cylinder engine, built specifically for Pagani by Mercedes-AMG, has benefitted from the research and development done for the Huayra BC, delivering power of 764 HP at 6200 RPM, with a torque of over 1000 NM already available at 2400 RPM. Equipped with the most cutting edge technology, the twin-turbo, 12 cylinder, narrow angled 60 degree engine with 5,980 cm3 has been developed to satisfy both the international homologation standards and the even more stringent Pagani internal standards, resulting in a driving experience both relaxed and electrifying. The turbines have been developed to provide an immediate throttle response without delay, providing the driver with full control of the vehicle. The dry sump lubrication allows for perfect engine response, even under the most extreme lateral acceleration conditions. The M158 motor is approved for the most restrictive EURO 6b and Carb environment regulations.
The extraordinary power and torque of the Huayra Roadster is powered by a new gearbox seven-speed AMT successfully developed for the Huayra BC. Built by X-Track, it incorporates a hydraulic and electronic activation system and is combined with new carbon synchronizers, resulting in seamless and absolute precision when shifting, thanks also to the development of a new ECU together with Automac. The differential is electronic, with an advanced control system developed in conjunction with Bosch, ensuring adaptation to all possible driving conditions: from day to day drivability to track performance, always providing driver stability and exceptional vehicle safety. The weight of entire unit, including the electronic differential, is approximately 40% less than the standard dual-clutch gearbox. The gearbox itself is mounted in a transverse position, significantly reducing the polar inertia of the entire vehicle and moving optimally at the center of gravity of the car. This results in a safe understeering response of the Huayra Roadster, ensuring comfort and safety for road driving and predictable behavior and control on the track.
The refinement of the suspension of Pagani Automobili creations has always been a point of pride and a key component in the design of the cars signed by Horacio Pagani. In the same way the development of the technology behind the Zonda R flowed naturally into the development of the technology of the Huayra Coupe, the Huayra BC development was the staging ground for the Huayra Roadster. Every concept learned from the previous model is applied and further developed for the new model. All of the suspension assembly is a work of art and a concentration of the latest technology, made in a lightweight aluminum alloy, called HiForg, designed specifically for the Huayra Roadster. This lightened the car by 25%, compared to the Huayra coupe, an extraordinary result for a car already considered the paragon in optimizing power-weight ratio. This sophisticated and technological marvel enables in the Huayra Roadster perfect behavior under any driving situation.
A long time partner of Pagani, Brembo has always delivered outstanding performance to Pagani cars. Since the Zonda F in 2006, Pagani cars have some of the shortest recorded stopping distances for 100-0 and 200-0. Certainly, the lightweight form of the car helps, but the results are a testament to the power and efficacy of the braking system. For the Huayra Roadster, Brembo has developed a new carbon ceramic (CCM) implant with 380×34 mm and a 6-piston caliper in the front and 380×34 mm, 4-piston caliper at the rear. The design of the caliper has been developed by Pagani and Brembo to decrease as much as possible the weight of the unsprung mass, resulting in a perfect balance of beauty and technological advancement. The most advanced brake caliper Brembo has ever created.
“Power is nothing without control.” This is the famous mantra that drove the Pirelli engineers to sculpt and design a specific rubber for the Huayra Roadster tires, allowing the vehicle to achieve an incredible performance of 1.8 g of lateral force. Performance was not the only factor in consideration for the development of the new tire; the Pirelli PZero Corsa for the Huayra Roadster was also designed to have a lower rolling resistance, reducing fuel consumption and CO2 emissions into the atmosphere. Developed and built inside Pirelli “MIRS” Modular Integrated Robotized System, the department for the manufacturing of high performance tires, the new Pirelli PZero Corsa measures 21 inches in the rear and 20 inches in the front. Developed along with Horacio Pagani, the tire displays for the first time the “HP” logo on the shoulder.
Continuing intensive development over the past five years, Pagani Automobili and Bosch have developed a new ESP system for the Huayra Roadster – an electronic stability control system enhancing the dynamic capabilities of the Huayra Roadster without ever being invasive, without ever giving the impression that any power other than the pilot himself has control of the vehicle. The system is a natural extension of the dynamic abilities of the car. It has always been a baseline requirement from the earliest design phases that the car must be mechanically sound with safe understeering, before starting the development of electronic control systems. The development started on the Huayra BC and was refined for the characteristics of the Huayra Roadster, leading to the identification of five distinct driving modes: Wet, Comfort, Sport, Race and ESC Off. Each with its own soul, fully maximizing the potential of the latest creation from the atelier of San Cesario sul Panaro.
