Lamborghini has officially unveiled its track-focused Huracán Performante at this week’s Geneva motor show, after the car was previously seen in camouflage guise at the Nürburgring setting a new production car lap record of 6:52.01 minutes – that’s 5 seconds faster than the Porsche 918 Spyder, the previous record holder.
The Performante uses the most powerful V10 produced to date by Lamborghini. Distinguished by a new bronze manifold, the mid-mounted 5.2-litre engine generates 631 bhp and 443 lb-ft of torque, while delivering a 0 to 62 mph time of 2.9 seconds and a top speed of 202 mph.
Managing a dry weight of 1382 kg, the Performante therefore achieves a power-to-weight ratio of 464 bhp per tonne.
As well as re-working the car’s seven-speed dual-clutch automatic transmission in order to match the increased performance, Lamborghini’s engineers have also redesigned the exhaust system to achieve weight reduction and less back pressure. The exhaust pipes, positioned at a higher and more central position, deliver a more aggressive sound as a result.
Further revisions include changes to the suspension system, which has been vertically stiffened by 10% over the Huracán coupé, via both springs and bars. Roll stiffness is also said to have been improved by 15%. The stiffness of the radial and axial arm bushings has been improved by 50%, improving lateral control of the car.
Other chassis details include custom designed bronze 20″ forged rims, wrapped in bespoke Pirelli P Zero Corsa tyres.
Externally, the car takes on a racing car look somewhat like the Lamborghini Super Trofeo racer, with design modifications carried out to both the front and rear sections.
Key functional elements that Lamborghini is keen to highlight include the addition of a new active aerodynamic system that uses electronically-controlled flaps located within both the front spoiler and rear wing structure to optimise and manipulate air flow.
For example, when the system is off, the active flaps inside the front spoiler are closed, generating high downforce for high speed cornering and full brake conditions. When it switches to on, the front flaps are opened, 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 reduces drag and allows for greater acceleration and top speed.
At the rear, 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 claimed to be 80% lighter than a traditional hydraulic system. And when the system 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 vertical downforce – 750% more than a Huracán coupé, according to Lamborghini engineers.
Along with the engine bonnet, rear bumper and aerodynamic diffuser, the front and rear spoiler are also both made from a new forged carbon-fibre-composite material which the Italian manufacturer has developed in-house.
Further use of the same material is seen on the inside, particularly with the air vents, paddles, door handles and the centre console.
There’s also a special graphic in the dashboard display which shows when and how the active aerodynamic system is working, including aero vectoring.
First customers deliveries of the new Huracán Performante are expected later on this summer.
