Lamborghini’s New Hybrid Sports Cars Will Deliver More Than 1,000 Horsepower

Lamborghini has unveiled 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 the brand celebrates its 60th anniversary this year. An all-new architecture with new powertrain delivers more than 1000 CV (stands for Constant Velocity: 1CV = 1.103HP ) in total, combining the power of a brand new 12-cylinder internal combustion engine with three electric motors and a double clutch gearbox that makes its debut on the 12-cylinder Lamborghini.

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. This is mounted transversely and placed for the first time behind the combustion engine. 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.

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 (pictured), which used a 25 kW electric engine to support the previous generation of V12, storing the electrical energy in a supercapacitor.

The LB744 introduces a hybrid architecture and a new generation of V12. 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 maximising performance.

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. In total it weighs just 218kg. The LB744 features the engine rotated 180 degrees compared to the Aventador layout. 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. Specific power is 128 CV per litre, the highest output in the history of Lamborghini’s 12-cylinder engines, while maximum torque is 725Nm at 6,750rpm.

The LB744 is engineered specifically for a four-wheel drive powertrain. Along with 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. A third electric motor positioned above the eight-speed double-clutch gearbox that supplies 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 725Nm produced by the internal combustion engine and 350Nm from each of the front electric motors. In total, the power unit delivers a combined maximum output of 1015 CV.

With all the electronic trickery working in tandem with the glorious V12, we can be assured that future flagship Lamborghinis will still supply a full-fledged sensory assault. Lamborghini might have order books filled to the brim yet again, even more so when current order banks are well over 1.5 years…
