Lamborghini described the gasoline-electric hybrid drivetrain for the Aventador's replacement earlier in March 2023. The vehicle, internally referred to as LB744, is still a mystery, but the company did share how it managed to keep the hybrid system's weight under control.
The LB744 was constructed by Lamborghini around a brand-new chassis known as a "monofuselage," which is formed of a front framework made of Forged Composites, an avant-garde material the business has been using since 2008. Although the now-retired Aventador had an aluminum front component in addition to its carbon-fiber monocoque. The benefits of switching to a composite structure are numerous: It makes the overall monofuselage 10% lighter than the Aventador's chassis and is 20% lighter than the front structure of the Aventador.
High-strength aluminum alloys were used to construct the structure out rear that houses the hybrid system's components as well as the engine, transmission, and other components. It includes two hollow castings into which the powertrain's suspension system and the shock towers of the rear suspension system are integrated. Once more, this design reduces the amount of components needed to manufacture the car, hence saving weight.
An eight-speed dual-clutch automatic transmission mounted transversally behind the engine, a small electric motor built into the transmission, two electric motors on the front axle (one per wheel), and a 3.8 kilowatt-hour lithium-ion battery make up the gasoline-electric plug-in hybrid drivetrain that powers the LB744.
