Lamborghini says it used knowledge from its Super Trofeo motorsports program to improve engine airflow efficiency, adopting new titanium intake valves with higher lift and new exhaust pipes that mount higher and more toward the center of the car. The bronze finish on the intake manifold, visible through the rear glass, is meant as a nod to previous special-edition engines like that on the Diablo 30th Anniversary, while the engine cover partially done in exposed carbon fiber does the same to the lightweight philosophy that guided Performante development.
The Huracán Performante uses an aluminum-and-carbon-fiber spaceframe, while the body panels are formed from aluminum and Lamborghini’s trademarked Forged Composite carbon-fiber technology. Shifting to this composite for the engine cover, front splitter, rear wing, and the rear fascia and diffuser pared about 88 pounds. Lamborghini claims the dry weight (without fluids) is 3047 pounds with a 43/57 front/rear distribution; full of fluids, the Performante should weigh about 3350 pounds.
