Lamborghini has released the first details of the plug-in hybrid powertrain that is destined to debut in the successor to the Aventador. The future supermodel is codenamed LB744 and uses an all-new naturally aspirated 6.5-liter V12 engine. Compared to the model it replaces, the new machine from Sant’Agata Bolognese has the engine rotated 180 degrees.
The engine weighs 218 kg and is 17 kg lighter than its predecessor. It’s also much more powerful, producing 813PS at 9250rpm and 725Nm of peak torque.
A powerful V12 is only part of the powertrain, as Lamborghini’s new flagship will use a hybrid setup. While SUS sends power to the rear wheels, two electric motors drive the front axle. Located above a newly developed eight-speed dual-clutch automatic transmission, a third electric motor can direct its power to the rear wheels depending on the driving mode and road conditions.
With the combined power of the V12 and three electric motors, the new LB744 will have a total of 1,000 hp. Engineers installed the DCT transversely, behind the longitudinally mounted V12 to make room for the lithium-ion battery in the tunnel. Weighing in at 193kg, the transmission is not only lighter than the Huracan’s, but also shifts gears faster.
The 3.8 kWh battery is placed in the central tunnel, it can be charged with a power of up to 7 kW and it takes half an hour to charge the full capacity. The battery can also be charged via regenerative braking of the front wheels or directly from the V12 in just six minutes. The LB744 has all-wheel drive, but works like a front-wheel drive car when in reverse. Lamborghini’s next supercar can also operate in electric mode with all-wheel drive.
