Lamborghini Huracán Perfomante Revealed at the 2017 Geneva Motor Show

Automobili Lamborghini unveiled the Huracán Perfomante at the 2017 Geneva Motor Show, combining new lightweight technologies, active aerodynamics with aero vectoring and a new set-up of chassis, all-wheel-drive system and further improved powertrain. The Huracán Performante is the result of Lamborghini innovations, producing a super sports car balanced between achieving the best lap times on a circuit with the most engaging and dynamic road driving. On 5 October 2016, the Lamborghini Huracán Performante set a new production car lap record of 6:52.01 min on the Nürburgring Nordschleife in Germany.

Lightweight Engineering

Based on a hybrid aluminium and carbon fibre frame, the Huracán Performante’s body is produced from aluminium in conjunction with significant use throughout of Lamborghini’s award-winning Forged Composite. Using chopped carbon fibres in a resin, Forged Composite allows the creation of lightweight, complex geometrical shapes beyond that possible with traditional carbon fibre composite materials, while maintaining optimum stiffness.

The Performante features Forged Composite in structural components including front and rear spoiler, the engine bonnet, rear bumper and aerodynamic diffuser, contributing to the car’s weight reduction of 40 kg.

Active Aerodynamics – Aerodinamica Lamborghini Attiva (ALA)

The Lamborghini Huracán Performante adopts Aerodinamica Lamborghini Attiva (ALA): ALA is also the Italian word for wing. This patented active aerodynamic system developed by Lamborghini for the Huracán Performante provides an active variation of aero load for high downforce or low drag.

The system is completely integrated into the vehicle in terms of design, weight and performance. The front spoiler integrates the electric motor of the front ALA system, built in a carbon forged frame with active flaps on the top exterior surface. The rear bonnet is designed around the air ducts to the rear wing as well as the wing pylons.

Lamborghini’s Piattaforma Inerziale (LPI) governs all the car’s electronic systems in ‘real time’ and is perfectly integrated with the ALA system, activating the ALA system flaps in less than 500 milliseconds to ensure the best aerodynamic set-up of the car in every driving condition.

When ALA is off, the active flaps inside the front spoiler are closed, generating the desired high downforce for high speed cornering and full brake conditions. When ALA switches to on the front flaps are opened by the front electric motor, reducing air pressure on the front spoiler and directing air flow via an inner channel and through the specially shaped underside of the car. This drastically reduces drag and optimizes conditions for maximum acceleration and top speed.

In the rear of the Performante four ducts are installed below the rear bonnet. The two central ducts are always open to allow underhood ventilation and exhaust cooling, while the two external ducts are connected to the inner channels of the rear wing. The air flow through the rear wing channels is controlled by two electro-actuated flaps. The entire system is 80% lighter than a traditional hydraulic system.

When ALA is off the rear flaps are closed, permitting the rear wing to act as a traditional fixed wing. Stability is enhanced in high-speed cornering and full braking by creating maximum vertical downforce; 750% more than a Huracán coupé.

The LPI turns on the ALA in high throttle conditions, opening the rear flaps to allow air through the rear wing’s inner channels and directing air flow through ridges underneath the wing. This reduces drag and maximises the car’s acceleration and top speed capabilities.

In addition, the rear wing’s inner air channel is split right and left, allowing aero vectoring for high speed cornering. Depending on the direction of the turn, the LPI instructs ALA to be switched on in either the right or left side of the spoiler, increasing downforce and traction on the inner wheel, counteracting the load transfer in rolling conditions. This in turn optimises the chassis’ momentum, requiring a reduced steering angle and improving the car’s overall dynamic stability.

Design

The Lamborghini Huracán Performante contains the DNA of a true Lamborghini, with its design unmistakably describing and emphasising the car’s purpose and inherent technologies, like a piece of technical art.

Reflecting the pure lines and performance of Lamborghini Super Trofeo race cars, the design also takes inspiration, particularly at the rear, from naked performance motorcycles, with their exposed frames and ‘streetfighter’ structures expressing function and performance.

Moreover, the design highlights the active aerodynamics (ALA) and lightweight build that are so integral to the car. Gloss, naked Forged Composite with its ability to be shaped or moulded in a single piece, is always used in ALA components, alongside matt and gloss black carbon fibre features contrasting with the matt body colour: shown in a new matt orange (Arancio Anthaeus) on the Huracán Performante in Geneva.

The new front is sophisticated and razor-blade sharp like a race car, with the design of the air intakes and splitter giving the impression of incisors, reminiscent of a striking snake. The active aerodynamic front spoiler is clearly visible in Forged Composite. The front bumper has no grills emphasising lightweight, efficiency and sportiveness.

The engine bonnet in Forged Composite emphasises its lightweight construction. Air intakes are integrated in the engine bonnet to provide airflow to the rear wing inner ducts and cooling air to the engine, with a Plexiglas cover over the engine inside. The V10 power plant’s manifold cover in bronze, a finish used in other special edition engines, is a reminder of Lamborghini heritage as well as denoting the enhanced engine and increased power output.

The racing inspired and fascinating rear, features extensive carbon fibre, with Forged Composite components reinforcing the significance of active aerodynamics. The rear wing with integrated air ducts could only have been created in one piece using the Forged Composite technology.

The sportiness of the Performante’s design is exemplified by the high-mounted exhausts, similar to extreme sports motorcycles, which create a more direct physical connection with the engine. The rear diffuser in matt black is directly inspired by Lamborghini Super Trofeo race cars, in both appearance and function. A trapezoid line from the bottom of the diffuser, also in Forged Composite, emphasises the width of the car’s rear: technical and sporty with an immense presence.

From the side, the design is characterised by the accelerating line of the rocker cover with air intakes in matt black, the Italian tricolore colours of the Performante’s Sant’Agata Bolognese birthplace on the doors, topped with wing mirrors in shiny black. The lightweight, Narvi 20″ forged wheels, dedicated to the Huracán Performante, are painted in bronze.

Powertrain and performance

The enhanced naturally aspirated Huracán engine is the most powerful V10 produced to date by Lamborghini. Outputting 640 hp (470 kW) at 8,000 rpm and producing 600 Nm of torque at 6,500 rpm, it is distinguished by a new bronze manifold that draws on the heritage of previous special edition engines such as the Diablo 30th Anniversary power plant.

The Performante’s new powertrain draws on sophisticated technologies including developments from Lamborghini’s motorsports program. Engine fluid dynamics for both intake and exhaust have been optimised, as has the V10’s air intake system with reduced loss improving responsiveness. New titanium valves allow higher valve lifts to increase engine permeability and performance.

The exhaust system has been redesigned to achieve weight reduction and less back pressure. The exhaust pipes, positioned at a higher and more central position, deliver a more aggressive sound in high-performance use, resonant of motor racing.

The car’s powerful engine produces an optimised torque curve, with more than 70% of torque already available at 1,000 rpm. Reflecting this, Lamborghini’s seven-speed dual clutch transmission has been also optimised in order to match the increased performance.

The Performante’s dry weight is just 1,382 kg, giving a weight to power ratio of 2.16 kg. Weight distribution front and rear is 43/57 %. Accelerating from 0-100 km/h in 2.9 seconds, the Huracán Performante is propelled from 0 to 200 km/h in 8.9 seconds, and brakes from 100-0 km/h in 31 m.

Chassis and set-up

The Lamborghini Huracán Performante’s suspension system has been revised, reflecting the Performante’s purpose as a track and performance-oriented car. The suspension has been vertically stiffened by 10% over the Huracán coupé, via both springs and bars, and roll stiffness improved by 15%. The stiffness of the radial and axial arm bushings has been improved by 50%, significantly enhancing lateral control of the car.

The double wishbone system, front and rear, features passive dampers with optional magneto rheological suspension. Both systems, passive and active suspension, are designed to improve body and wheel control especially on track.

Electromechanical power steering is offered as standard with optional variable ratio Lamborghini Dynamic Steering (LDS). Both the Huracán Performante’s electronic power steering and LDS have been significantly recalibrated to provide highly responsive steering with maximum driver feedback in all three driver modes: Strada, Sport and Corsa. In Corsa mode, designed for high performance and track environments, the steering offers a racing feeling with a significantly reduced steering ratio variation.
