Lamborghini unveiled a new glimpse on Tuesday of the LB744, the replacement for its Aventador model. With specifications that are already impressive—a V12 engine with three electric motors delivering 1,001 horsepower—Lamborghini disclosed more details about the car’s weight-saving fundamentals. We already knew that the LB744’s engine weighs only 481 pounds, making it the lightest V12 ever used in Lamborghini’s road cars. It’s also the most powerful, boasting 813 horsepower before the hybrid components kick in.
The weight reduction efforts extend beyond the engine. The automaker has dedicated attention to reducing the weight of the LB744 in comparison to the outgoing Aventador, shedding weight in preparation for the electric motors and batteries by focusing on the chassis.
At the heart of the LB744’s design is its lightweight monocoque structure, referred to by Lamborghini as the “monofuselage,” a fitting name given the automaker’s claim that its chassis draws inspiration from aeronautics.
All primary components forming the front chassis and monofuselage of the car are crafted from carbon fiber. The tub, firewall, and even the A-pillar are exclusively composed of carbon, connected using a distinct monolithic mounting method named a “rocker ring” by Lamborghini.
For those enthusiasts craving more carbon fiber, it’s worth mentioning that the LB744’s front structure is entirely made from Forged Composites, a material consisting of resin-soaked carbon fibers—a first in its class of super sports cars.
The LB744’s rocker ring encloses and connects the car’s carbon elements.
Due to its full carbon fiber construction, the monofuselage offers a weight reduction of 10% compared to the older Aventador chassis, while boasting a 25% increase in torsional stiffness—as much as double that of the two-decade-old Murcielago. Furthermore, the LB744’s carbon fiber front frame is 20% lighter than the Aventador’s aluminum build.
Despite the car’s construction containing some metal, Lamborghini still utilizes high-strength aluminum alloys for the rear chassis. The automaker ensures that significant weight reductions and increased rigidity have been achieved in this area through smart engineering decisions in structural casting.
Noteworthy is the abandonment of the pushrod suspension used in the Aventador, with the LB744 now featuring an upright spring at each corner. These modifications, alongside other adjustments to support the hybrid drivetrain, offer a tantalizing glimpse into the changes made to the platform.
Before witnessing the final masterpiece in all its splendor, it will take some time. However, the established equation already includes broad hips, a low roof, and a bold design that complements its unrefined exhaust tone. Regardless, I am confident that the fiery bull will continue to astonish us with the end result, even if it is completely reserved before we have the opportunity to make a purchase.
