increase in power, braking performance, aerodynamic efficiency and downforce. The result: performance experience equivalent to that of the Le Mans Prototype 2 race cars.
The outer design of the car, which incorporates the innovative Class A carbon fiber that contributes to a 38 percent increase in stiffness characteristics at the same weight, emphasizes aerodynamic efficiency from the very front of the car through the back. For example, the design team conceived of a compact and aerodynamically efficient layout through a sophisticated system of air conveyors to manage the optimal distribution of the cooling required between the brake discs, calipers and water radiator. And from the front bonnet, a complex fusion of shapes and surfaces not only allows the venting of air and heat accumulated in the arches of the front wheel but helps generate an air flow that aerodynamically cleans the rear engine compartment.
Then, there is the long tail, which, with the 190 mm (~ 7.5 inches) extension of the rear end, balances the previously mentioned features. For example, the sinuous rear hood supports the new central stabilizing fin while the group of supports integrated into the rear wing equipped with metal lateral fins evoke icons of past designs. The bodywork is completed by a rear extractor that incorporates the characteristic aerodynamic fins essential to linearize the air flows in the rear part of the vehicle. Such evolutions also lead to an increase in the surface of the aerodynamic underbody. Taken collectively, these and other improvements
allows maximum aerodynamic performance, guaranteeing safe and predictable behavior in all conditions. Consider, for example, with the same resistance, the result is an impressive increase in downforce of 45 percent accompanied by an increase in efficiency of 21 percent. The open-top configuration also results in a gain in vertical load, both at the front and rear, increasing the total downforce by a further five percent. Such efforts required meticulous balancing, with 45 percent – 55 percent distribution throughout the speed envelope.
Inside the cockpit, the Huayra R Evo offers the driver full frontal visibility whether configured for right- or left-hand driving. It also incorporates various element made from Carbo-Titanium HP62-G2 and Carbo-Triax HP62 to reduce weight – from the safety cage to the seat and headrest structures. Seats are upholstered in fireproof material and equipped with six-point seat belts.
Under the hood, the Huayra R Evo project continues a strategic collaboration between Pagani and HWA AG. Building off an updated and enhanced engine, the new engine, named the Pagani V12-R Evo engine, delivers a power of 900 hp (662 kW) at 8,750 rpm and a maximum torque of 770 Nm, available from 5,800 up to 8,200 rpm. To achieve such performance, engineers needed to focus on such fundamental components as the intake manifold, the engine control unit, and the design of the exhaust system.
The six-speed sequential gearbox was also designed in collaboration with HWA AG. Actuated by a racing clutch with 3 sintered metal discs, the front-mesh gearbox guarantees a friction efficiency of 95 percent, offering maximum precision in gear insertion, extremely short shift times and an overall weight of just 80 kg (176 lb).
Suspension and braking have also been improved. Suspension has been improved with the integration of a heave damper, a third hydraulic element that separates the
