Lamborghini's Brilliant active aerodynamics - Huracán performante

The Lamborghini Huracán Smashed The Nürburgring Record.

From Lamborghini's Press Release On ALA:
"The 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 down force 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 maximizes 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 optimizes the chassis’ momentum, requiring a reduced steering angle and improving the car’s overall dynamic stability."
