Earlier in March 2023, Lamborghini detailed the gasoline-electric hybrid drivetrain that will power the Aventador’s successor. We still don’t know what that model (known internally as the LB744) will look like, but the company has revealed a way to control the weight of the hybrid powertrain.
The Lamborghini LB744 is built around a new chassis called Monocoque, consisting of a carbon fiber monocoque and a front structure made of forged composite, an innovative material the company has used since 2008 . While the now-retired Aventador has a carbon-fibre monocoque, its front structure is also made of aluminum. Switching to a composite structure offers many advantages: it is 20 percent lighter than the Aventador’s front structure and helps make the overall monocoque 10 percent lighter than the Aventador’s chassis.
At the rear, the structure housing the engine, transmission and hybrid system components is made of high-strength aluminum alloy. It contains a pair of hollow castings into which the shock towers of the rear suspension system and the suspension system of the powertrain are integrated. Again, this layout reduces weight by reducing the number of parts needed to assemble the car.
The LB744 is powered by 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, a small electric motor integrated into the transmission, and a front There are two electric motors on the axle (one for each wheel), and a 3.8-kWh lithium-ion battery pack, housed in the former transmission tunnel. The total output of the system is 1,001 horsepower. This layout offers all-wheel drive, meaning there is no mechanical connection between the front and rear axles.
Lamborghini will unveil the LB744 “in a few weeks”.
