“The Huracán Performante is the convergence of technological developments to produce a car delivering perfect performance,” says Automobili Lamborghini Chairman and Chief Executive Officer Stefano Domenicali.

So let’s take a look.

The vehicle is based on a hybrid aluminum and carbon fiber frame. Lamborghini has developed a material that it calls “Forged Composite,” which is essentially chopped carbon fibers bonded in a resin so that they are able to produce complex shapes that provide high levels of stiffness. They’re using the material in the front and rear spoiler, engine bonnet (with integrated air intakes), rear bumper and aerodynamic diffuser. All in, they calculate a weight save of 40 kg. (The vehicle has a total weight of 3,040 lb.)

And because the material has aesthetic value as well as functional, there is use of the Forged Composite on the interior of the vehicle, for air vents, shift paddles (for the seven-speed dual-clutch transmission), door handles and the center console.

The car is powered by a naturally aspirated V10 that produces 640 hp @ 8,000 rpm and 443 lb-ft of torque at 6,500 rpm, with more than 70 percent of the torque being available at 1,000 rpm. Because this is a special engine, they’re using a bronze manifold. There are titanium valves.

The car features Lamborghini’s permanent four-wheel-drive Haldex fifth-generation system, which is electronically controlled and deploys a rear mechanical self-locking differential. 

A key consideration overall: aerodynamics. The vehicle features what’s called “Aerodinamica Lamborghini Attiva” (ALA). And it so happens that ala is the Italian word for wing.

ALA is an active aerodynamic system that provides adjustment for both high down force and low drag, depending on requirements.

The front spoiler features an electric motor that controls the flaps, based on the inputs from the Lamborghini Piattaforma Inerziale (LPI), which controls electronic systems, including that of the ALA. The front flaps can be activated in less than 500 milliseconds.

When the ALA is off, the active flaps in the front spoiler are closed, thereby providing high downforce for cornering and braking. When the ALA is on, the front flaps are opened, to reduce the air pressure on the spoiler. The air is directed to channels on the bottom of the vehicle.

Around back there are four ducts, two of which are always open for engine ventilation and exhaust cooling. The other two 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. When the ALA is off, the rear flaps are closed, so the rear wing performs as a conventional fixed wing, providing maximum vertical downforce. According to Lamborghini, the downforce exerted is 750 percent more than that of a Huracán coupe.

During high-throttle conditions, the LPI turns on the ALA, which opens the rear flaps so that air moves through the inner channels in the rear wing and subsequently flows in ridges beneath the wing, thereby reducing drag. The inner channels are separated, right and left, so that the LPI can control which side air is channeled during cornering maneuvers, increasing the downforce on the inner wheel to help the car to carve the turn.

And about the performance: the vehicle accelerates from 0 to 62 mph in 2.9 seconds and the top speed is in excess of 202 mph.
