Lamborghini highlights the carbon fiber chassis of the Aventador successor

Earlier in March 2023, Lamborghini detailed the gasoline-electric hybrid drivetrain that will power the Aventador’s successor. We still don’t know what the model (internally called the LB744) looks like, but the firm touted the hybrid system as a way to keep its weight under control.

Lamborghini built the LB744 around a new chassis called a “monofuselage”, consisting of a carbon-fibre monocoque and a front structure made of forged composites, which the company has used since 2008. While the now-retired Aventador also featured a carbon-fibre monocoque, its front structure was made with aluminium. Switching to a composite structure offers several advantages: it is 20% lighter than the Aventador’s front structure, and it helps to make the overall monofuselage 10% lighter than the Aventador’s chassis.

At the rear, the structure on which the engine, transmission and parts of the hybrid system are mounted is made with high-strength aluminum alloys. It consists of a pair of hollow castings that are integrated into the rear suspension system’s shock towers and the powertrain’s suspension system. Here again, this layout saves weight by reducing the number of parts that come together to assemble the car.

Power for the LB744 comes from a gasoline-electric plug-in hybrid drivetrain consisting of a new, 6.5-liter V12 engine located directly behind the passenger compartment, an eight-speed dual-clutch automatic transmission mounted transversely behind the engine It consists of an electric motor integrated into a small transmission, two electric motors on the front axle (one per wheel), and a 3.8-kilowatt-hour lithium-ion battery pack in what was formerly the transmission tunnel. The system’s total output checks in at 1,001 horsepower. This layout provides through-the-road all-wheel-drive, meaning there is no mechanical connection between the front and rear axles.

Lamborghini will unveil the LB744 in “a few weeks”.
