(March 13, 2023) Lamborghini has unveiled the first details of the first HPEV (High Performance Electrified Vehicle) hybrid super sports car, codenamed LB744, which will soon make its debut in the year that Lamborghini celebrates its 60th anniversary. With the LB744, Lamborghini has established a new benchmark in terms of performance and driving pleasure.

An all-new architecture combines 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.

One electric motor will be mounted transversely and integrated into the car's eight-speed gearbox, while the other two each will power a front wheel. Together, the engine and the motors can produce more than 986 horsepower, the company says.

Lamborghini says the engine weighs just over 480 pounds, about 37 pounds less than the V-12 that powered the Aventador. As part of the engine's design, Lamborghini rotated it 180 degrees compared with the Aventador, reengineered the air intake ducts to guarantee optimal airflow into the combustion chamber, and optimized the chamber itself. The result is a power level of 126 hp per liter, the brand says.



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. It’s an innovative solution, designed to reduce emissions compared to the previous V12 while maximizing performance.

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. 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 new combustion system is also characterized by an increased compression ratio (12.6:1 compared to 11.8:1 for the Aventador Ultimae). The fluid dynamics of the exhaust have also been improved to reduce counter-pressure at high revs and increase the specific power output.

From the very beginning, Lamborghini cars were famed for their uniquely emotional and unmistakable sound. 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 LB744 retains one of Lamborghini’s strongest traditions — four-wheel drive. 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. 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.

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 534 pound-feet of torque produced by the internal combustion engine and 258 pound-feet from each of the front electric motors.

The two electric motors at the front are oil-cooled axial flux units and offer an exceptional weight-to-power ratio: 18.5 kilograms from each of the 110 kW units. As well as providing power to the front wheels, they also have a torque vectoring function, optimizing driving dynamics, and recuperating the energy produced under braking. When in electric mode, the LB744 is front-wheel drive only to optimize energy consumption, while electric drive to the rear axle is activated on demand when needed.
