Ahead of the reveal of the V12, hybrid-powered successor to the Aventador, Lamborghini revealed an aeronautics-inspired monocoque concept made entirely from carbon fiber

For the past 60 years, Automobili Lamborghini has been at the forefront of innovation. Just weeks away from launching its first hybrid plug-in V12 High-Performance Electrified Vehicle (HPEV), the Sant’Agata Bolognese brand unveils a brand-new technical solution that is unrivaled in today’s automotive landscape. This solution – LB744 – functions on the basis of a new aeronautics-inspired chassis, dubbed ‘monofuselage’. Not only does it boast a completely multi-technology carbon fiber monocoque, but its front structure is composed of Forged Composites; a special material crafted from short carbon fibers soaked in resin. Incredible as it may sound, this technology was patented and used by Lamborghini for its first structural applications as far back as 2008.

The monofuselage of the LB744 marks considerable progress from its predecessor, the Aventador. Not only is it sturdier and lighter, but it also brings improved driving dynamics. Moreover, it is the first to be kitted out with an all-carbon fiber front structure – twice as effective in terms of energy absorption as the Aventador Ultimae’s aluminum front frame – with added benefits such as reduced weight.

Compared to its aluminum predecessor, the LB744 monofuselage is 10% lighter, and the front frame is 20% lighter. Furthermore, the torsional stiffness has been increased to 40,000 Nm/°, an improvement of +25% compared to the Aventador, ensuring the best dynamic performance in the class.

The design of the new monofuselage is based on integration between components, achieved by combining Forged Composites technology and a single-piece CFRP rocker ring. This rocker ring – unique in the super sports car arena – functions as a supporting structure that encompasses and interconnects the tub, front firewall and A pillar.

In addition to optimizing efficiency, Forged Composites components reduce the energy consumption of cooling equipment and waste material generation during the manufacturing process.

The traditional method of composite production with pre-impregnated material was employed for the roof construction. Autoclaved carbon fiber is used to satisfy stringent technical, aesthetic and quality requirements. In addition, craftsmanship from years of in-house production of composite components creates a superior hand lay-up process. This decision grants the customer extensive choices for customizing their roof.

The rear chassis is made of high-strength aluminum alloys and features two important hollow castings in the rear dome area: these combine the rear suspension’s shock towers and the powertrain suspension into one component with a closed inertia profile, which reduces weight, increases rigidity, and reduces welding lines significantly.

With the LB744, a new “year zero” has been reached when it comes to carbon fiber used in car production, as summed up by the acronym AIM (Automation, Integration, Modularity). Lamborghini uses automation to transform materials, while preserving traditional manufacturing methods, such as composites, by introducing automated and digitalized processes.

The process of compression molding encompasses many functions to create an integrated component. Preheated polymers are used to construct components of varied shapes, lengths, and thicknesses, allowing maximum interconnection with high torsional stiffness. Modularity makes technologies both malleable and dynamic, permitting them to satisfy the needs of each product.
