In total, the power unit delivers a combined maximum output of 1015 CV. The combined torque from the combustion engine and three electric motors offers performance levels that are unique even within the domain of super sports cars, with 725 Nm produced by the internal combustion engine and 350 Nm from each of the front electric motors. There’s also a third electric motor positioned above the eight-speed double-clutch gearbox that can supply power to the rear wheels, depending on the selected driving mode and the conditions. As well as the internal combustion engine that provides power to the rear wheels, a pair of electric motors now make their debut on the front axle, each supplying traction to one of the front wheels. The LB744 retains one of Lamborghini’s strongest traditions: four-wheel drive. Particular attention has been lavished on the ‘soundtrack’ of the new L545 to emphasize the tone of the engine, already melodious at low revs and then rising to a natural harmonious crescendo. The fluid dynamics of the exhaust have also been improved to reduce counter-pressure at high revs and increase the specific power output.įrom the very beginning, Lamborghini cars were famed for their uniquely emotional and unmistakable sound. The new combustion system is also characterized by an increased compression ratio (12.6:1 compared to 11.8:1 for the Aventador Ultimae). The combustion within the actual engine has also been optimized, thanks to the regulation of ionization in the chamber with two control units: a solution already used in the Aventador and now transferred to the new model. The air intake ducts to the cylinders have been re-engineered to increase the supply of air and guarantee optimal airflow in the combustion chamber. Specific power is 128 CV per liter, the highest output in the history of Lamborghini’s 12-cylinder engines, while maximum torque is 725 Nm at 6750 rpm. The superquadro V12 puts out 825 CV at 9250 revs per minute thanks to the redesigned distribution system that supports a maximum rev range of 9500 rpm. The LB744 features the engine rotated through 180 degrees compared to the Aventador layout. In total it weighs just 218 kilograms: 17 kilograms less than the Aventador unit. The new L545 engine has a capacity of 6.5 liters and is the lightest and most powerful 12-cylinder engine ever made by Lamborghini. It’s an innovative solution, designed to reduce emissions compared to the previous V12 while maximizing performance. The car is launched as the very first High Performance Electrified Vehicle - HPEV: a plug-in hybrid super sports car equipped with a lightweight high-power lithium ion battery, housed within the transmission tunnel in the central section of the chassis. The LB744 introduces an unprecedented hybrid architecture and a new generation of V12. The first time that an electric motor was matched to a 12-cylinder internal combustion engine in a Lamborghini was in 2019 with the Sián, which used a 25 kW electric engine to support the previous generation of V12, storing the electrical energy in a supercapacitor. The very first Lamborghini model to sport this characteristic engine was the iconic 350GT launched in 1963. Lamborghini has been synonymous with V12 engines since the company was founded. The electric motors boost power delivery at low revs and can also turn the new LB744 into a purely electric car, reducing overall CO 2 emissions by 30% compared to the Aventador Ultimae. In what has been the transmission tunnel since the days of the Countach, there is a lithium-ion battery instead, which powers the electric motors. This is mounted transversely and placed for the first time behind the combustion engine. The car showcases an unprecedented layout: the naturally-aspirated 6.5-liter V12 mid-mounted engine is complemented by three electric motors, one of which is integrated into the new double-clutch eight-speed gearbox. With the LB744, Lamborghini has established a new benchmark in terms of performance and driving pleasure: an all-new architecture with new powertrain delivers more than 1000 CV in total, combining the power of a brand new 12-cylinder internal combustion engine with three electric motors and a ground-breaking double clutch gearbox that makes its debut on the 12-cylinder Lamborghini. Lamborghini has unveiled the first details of the first HPEV (High Performance Electrified Vehicle) hybrid super sports car, codenamed LB744, which will make its debut shortly in the year that Lamborghini celebrates its 60 th anniversary.
