10% Lighter, Stronger chassis with LB744 Monofuselage
Lamborghini recently divulged further news regarding the upcoming successor to the Aventador, referred to as LB744, presenting its revolutionary development and extensive use of carbon-fibre.
The Italian supercar brand has unveiled the new monocoque, which they have dubbed a “monofuselage”. Drawing inspiration from the aeronautical industry, this single-piece structure is crafted entirely out of multi-technology carbon fiber. The front part is made out of forged composites, a technology that the brand patented in 2008 and has since been used in structural applications.
LB744 will be a pioneering supercar equipped with a chassis composed totally of carbon fiber. This is the inaugural instance where Lamborghini has incorporated carbon fiber for crash protection parts.
The LB744 monofuselage shaves off 10% of the weight in contrast to the Aventador’s chassis, and its front frame is an astonishing 20% lighter than the preexisting aluminum one. Beyond being more lightweight, it also contributes to greater safety for the V12 Lamborghini through its capacity for energy absorption that outclasses the aluminum front frame featured on the Aventador by double.
It is crucial, yet in a vehicle of this caliber they also placed emphasis on vitality and superior maneuverability. Torsional stiffness has been increased by over 25% from the prior Aventador, giving Lamborghini expectation of achieving marked dynamic aptitudes.
The brand’s aspiration of maximum convergence between components inspired the introduction of a singular fuselage. An encompassing peripheral rocker ring constructed of Forged Composite was then added to foster this concept. This integral element links the different composite segments such as the center spine, front firewall, and A-pillar; providing unprecedented structural integrity and torsion tolerance. In the accompanying video, Chief Technical Officer Rouven Mohr stresses that significantly fewer distinct parts were utilized in this process.
For the construction of the roof, Lamborghini has chosen to go with the more classic autoclave composite production process featuring pre-impregnated material. This carbon fiber solution still adheres to the automaker’s rigorous standards and gives customers “maximum versatility in roof customization.”
Regarding the backside of the chassis, aluminum composites with superior durability have been employed. There are two hollow shapes in the rear canopy that gives space for uniting the rear shock absorber towers and the powertrain suspension into a single portion to create an enclosed inertia pattern. This leads to less mass (decrease in components once more) yet a greater firmness. One can anticipate it to be light-years ahead of the Aventador in terms of maneuverability, notwithstanding the inclusion of electric drive devices.
LB744 marks the dawn of a new “year zero” for the utilization of carbon fiber by the brand. This innovative approach can be encapsulated in the acronym “AIM,” which stands for Automation, Integration, and Modularity.
The incorporation of automated and digitalized production procedures is what automation pertains to. Lamborghini has highlighted that the same levels of excellence which have been maintained up till now are still upheld in its fabrication methods.
Integration is achieved through the use of compression molding, which utilizes preheated polymers to “enable the production of components with a wide range of lengths, thicknesses, and complexity,” allowing for the combination of multiple functions into one single part. This method guarantees high torsional stiffness, making it an ideal choice for many applications.
Thirdly, we come to Modularity, which entails making the employed technology malleable and proficient so that it can meet the particular necessities and desired attributes of each car created under these renewed systems, be it a Huracan substitution or something else.
It appears that Lamborghini is pursuing a route to modernize its production systems and achieve the assembly of vehicles with a lesser prospect for mistakes, along with more high-tech transformations allowing for improved agility and all at a more affordable price range without compromising on the distinct qualities and characteristics of each individual model.
We certainly look forward to getting an eyeful of the completed version, but right now it appears as though Maranello should be somewhat concerned.
