Introducing Lamborghini’s LB744
Lamborghini has unveiled the first details of its new hybrid super sports car, codenamed LB744, which is set to debut in the year of Lamborghini’s 60th anniversary. The LB744 is a High-Performance Electrified Vehicle (HPEV) is powered by a brand new 12-cylinder internal combustion engine, three electric motors, and a double-clutch gearbox, delivering more than 1000 CV in total.
The LB744 introduces a unique hybrid architecture and a new generation of V12, which maximizes performance while reducing emissions. The car is equipped with a lightweight, high-power lithium-ion battery housed within the transmission tunnel in the central section of the chassis. The battery contains pouch cells with an overall capacity of 3.8 kWh which lets the LB744 cover more than 10 kilometers in 100% EV mode. When the charge drops to zero, it can be recharged using ordinary domestic alternating and charging column current up to 7 kW in power and completely recharges in just 30 minutes. It can also be recharged under regenerative braking from the front wheels or directly from the V12 engine in just six minutes.
An unprecedented new layout
The LB744 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. 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 Lamborghini Countach, there is a lithium-ion battery instead, which powers the electric motors.
The LB744 retains four-wheel drive, with a pair of electric motors debuting on the front axle, each supplying traction to one of the front wheels. A third electric motor is positioned above the eight-speed double-clutch gearbox that can provide power to the rear wheels. The combined torque from the combustion engine and three electric motors offers exceptional performance levels even within the domain of super sports cars, with 725 Nm produced by the internal combustion engine and 350 Nm from each front electric motor. The power unit delivers a combined maximum output of 1015 CV.
A new generation V12
The LB744 introduces a new generation of V12, the lightest and most powerful 12-cylinder engine ever made by Lamborghini. The LB744’s engine is rotated through 180 degrees compared to the Aventador layout and 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 air intake ducts to the cylinders have been re-engineered to increase the air supply 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. The new combustion system also has 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.
Wet double clutch of course
The LB744 is equipped with a wet double clutch as the most efficient and performance-oriented solution, best capable of managing the 725 Nm of torque at 6750 rpm from the internal combustion engine. The new eight-speed gearbox is positioned transversally behind the longitudinal V12 engine to leave space in the tunnel for the lithium-ion battery that feeds the electric motors. The layout helps to keep the car’s wheelbase contained and supports effective weight distribution for the best driving dynamics.
The LB744 is an innovative solution designed to reduce emissions compared to the previous V12 while maximizing performance. Lamborghini has once again demonstrated that it’s at the forefront of automotive engineering with its latest contribution to the world of super sports cars.
