Lamborghini Aventador Successor's Cutting-Edge Carbon Fiber Chassis Unveiled

Video / Comments

The LB744's "monofuselage" is 10% lighter than the outgoing Aventador's chassis and stronger too.

Lamborghini has released more details about the upcoming Aventador successor, codenamed LB744, revealing its innovative and carbon fiber-rich architecture.

The supercar brand has detailed the new monocoque, calling it a "monofuselage" that takes inspiration from the aeronautical industry. Fashioned entirely out of multi-technology carbon fiber, the front structure is made out of forged composites, a technology patented by the Italian brand and used in structural applications as early as 2008.

LB744 will be the first supercar to ever be fitted with a front structure made entirely of carbon fiber. In fact, this is the first time that Lamborghini has used carbon fiber for crash elements.

This reduces weight - the LB744 monofuselage is 10% lighter than the Aventador's chassis and the front frame itself is 20% lighter than the outgoing aluminum setup - but it also makes the V12 Lambo safer with double the energy absorption of the Aventador's aluminum front frame.


That's very important, but in a car like this, dynamism and sharp handling are also top priorities too. Torsional stiffness has been improved by more than 25% compared to the outgoing Aventador, which Lamborghini expects to translate to class-leading dynamic capabilities.

The new monofuselage design comes from the ambition of maximum integration between the components. The supercar brand has developed a monolithic rocker ring and incorporated forged composites technology to further enhance the concept. This rocker ring encloses and connects the various forged composite elements like the tub, the front firewall, and the A-pillar, which means hitherto unseen levels of structural soundness and stiffness. As Chief Technical Officer Rouven Mohr explains in the above video, this also means that fewer individual parts are required.


For the construction of the roof, Lamborghini has elected to use the more traditional autoclave composite production method with pre-impregnated material. This carbon fiber solution still meets the automaker's high standards and also provides the customer with "maximum versatility in roof customization."

As for the rear part of the chassis, high-strength aluminum alloys were used. Two hollow castings can be found in the rear dome, which allows for the integration of the rear shock absorber towers and the powertrain suspension into a single component with a closed inertia profile. This translates to less weight (thanks again to fewer components) and more rigidity. Expect this to outmaneuver an Aventador with ease, despite the addition of electric drive units.

LB744 represents the start of a new "year zero" for the brand's use of carbon fiber. These new processes can be summed up in the acronym "AIM," which stands for Automation, Integration, Modularity.


Automation has to do with the introduction of new automated and digitalized production processes. Lamborghini is quick to point out that its manufacturing processes will adhere to the same high standards as before.

Integration refers to the amalgamation of numerous functions into a single part thanks to compression molding, which utilizes preheated polymers to "enable the production of components with a wide range of lengths, thicknesses, and complexity," guaranteeing high torsional stiffness.

Lastly, there's Modularity, which refers to making the applied technologies flexible and efficient in order for them to fit the specific requirements and intended characteristics of each car that is produced under these new methods, be that a Huracan replacement or something else.

AIM indicates that Lamborghini wants to modernize its production processes and manufacture cars with less room for error, more high-tech innovations that enable better dynamism, and at a lower cost without sacrificing individual model attributes and characteristics.

We can't wait to see the final product, but so far, it looks like Maranello has something to be worried about.
