Lamborghini has announced the technical features of its first HPEV (High Performance Electrified Vehicle), the codename ‘LB744’, ahead of its global launch. This vehicle is designed to provide absolute excitement and control in all driving conditions and grip situations, delivering a level of confidence and integration with the vehicle previously unexperienced by the driver. The all-new monofuselage structure is 10% lighter yet 25% more rigid than that of the Aventador.
Positioned at the top of its segment, the LB744 introduces a new hybrid powertrain and driving modes aimed at maximizing electric motor support, along with an innovative vehicle structure and balance. A total of 13 different driving modes, including a carbon-neutral mode, can be experienced based on a variety of innovative elements.
This new model features an unprecedented layout, becoming the first Lamborghini 12-cylinder model equipped with a dual-clutch gearbox. It is fitted with a newly developed 6.5-liter naturally aspirated V12 mid-engine, supported by three additional electric motors placed on the front e-axle.
Two of the motors are integrated with the new eight-speed dual-clutch transmission, positioned transversely behind the engine for the first time. The space previously reserved for the transmission since the Countach has now been filled with a high-power new lithium-ion battery that powers the electric motors.
Thanks to the new architecture, the weight distribution is optimized with a center of gravity of 44% at the front and 56% at the rear. With the wheelbase optimized, this vehicle achieves incredible agility and an effective balance for both street and track driving. These technological advancements have been further enhanced by the high stiffness of the anti-roll bars (11% improvement at the front, 50% improvement at the rear) and a reduction in steering ratio (10% reduction compared to the Aventador Ultimae). This design approach was already tested in the Huracan STO.
The functionality of the LB744 is further complemented by a four-wheel steering system, which provides agile responsiveness alongside a stable and accurate vehicle sense. The tires are fitted with new Bridgestone Potenza sport tires, featuring about 4% wider contact area at the front compared to the Aventador Ultimae.
For the first time in Lamborghini’s history, electric torque vectoring has been introduced, along with the LamboDynamica Vehicle 2.0 system. Electric torque vectoring enhances agility in tight cornering and stability in high-speed cornering by distributing optimal torque to each wheel, synergizing with the four-wheel steering system. Braking is engaged only when necessary to maximize efficiency, ensuring a more natural driving style and enhanced performance. During braking, the e-axle and rear electric motor charge the battery while alleviating the stress on the brakes.
Moreover, the chassis significantly contributes to the vehicle’s dynamics. The LB744 is the first Lamborghini to utilize a lightweight carbon fiber monofuselage structure, which is 10% lighter compared to the Aventador and boasts high energy absorption performance along with improved torsional rigidity (25% increase from the Aventador). This combination elevates the LB744’s stability, responsiveness, and compactness.
Active aerodynamics play a crucial role in achieving a new level of efficiency and downforce. Thanks to the front splitter and roof design, airflow is directed to the rear wing, improving efficiency by 61% and downforce by 66% under high load conditions compared to the Aventador Ultimae.
The semi-active wishbone suspension controlled by a Lamborghini Vertical Control system, specially designed for the LB744, electronically manages vertical force exchanges during sudden load transfers on track, adjusting suspension and rear wing movements in real-time.
To ensure the best performance driving scenarios, the brake system and cooling system have also been redesigned. Equipped with the latest generation CCB Plus (Carbon Ceramic Brakes Plus), the front calipers feature 10 pistons instead of the previous 6, coupled with 410x38mm discs, while the rear has 4-piston calipers with 390x32mm discs. The discs are covered with a friction layer to enhance heat management and comfort during brake operation.
Aerodynamics are enhanced by a pair of front suspension struts and wheel arch grilles that not only improve brake cooling but are also designed to draw airflow from the front diffuser to connect the brake channels, thus enhancing system efficiency. Additionally, two NACA ducts positioned in front of the rear wheels collect airflow beneath the vehicle, directing it to the rear brake cooling ducts.
With the hybrid system, three new driving modes — recharge, hybrid, and performance — have been added. These combine with Città, Strada, Sport, and Corsa modes. Selectable through two rotors on the newly designed steering wheel, the total of 13 modes provides a variety of driving enjoyment tailored to the situation, whether on the road or track.
The Città mode is designed for urban everyday driving, with zero carbon emissions. If the lithium-ion battery powering the electric motor needs to be charged and no charging station is available, the V12 engine kicks in to fully charge in just a few minutes (recharge mode). The suspension system, power control, and gearbox provide maximum comfort in this high fuel-efficiency mode, limiting peak power to 180 horsepower.
The Strada mode offers an upgraded sportiness while being suitable for luxurious everyday driving and long-distance trips. The always-active V12 engine ensures a constant state of battery recharging. The front e-axle supports torque vectoring and provides maximum stability at highway speeds with active aerodynamics.
Choosing the Sport mode sets the LB744’s character for an exhilarating and responsive driving experience, set up in three combinations. The combustion engine, supported by the hybrid system, performs impressively in all three scenarios, delivering a maximum output of 907 CV while providing a most attractive sound from the V12 engine. The gearbox responds at maximum responsiveness, and the suspension and aerodynamics enhance the vehicle’s agility and driving pleasure.
The Corsa mode is designed specifically for track use, emphasizing the LB744’s dynamic capabilities to the fullest while showcasing tremendous power and dynamism in performance and sound. In the performance mode, the powertrain delivers a maximum output of 1,015 CV, with hybrid system control designed to maximize torque vectoring and utilize the e-axle in front-wheel drive for an enjoyable sporty drive.
The Corsa recharge mode allows for prioritizing battery status to elevate maximum charge levels. Skilled drivers can deactivate ESC to feel maximum output without active control. Additionally, the “launch control” function enables the thrill of a maximum power start, activated by pressing a button located in the center of the left rotor.
Meanwhile, Lamborghini is progressing with its electrification roadmap, ‘Direzione Cor Tauri’ (Towards the Heart of the Taurus), across all lineups through 2024. The new LB744 will mark the first step towards hybridization of the entire model range.
