The first plug-in hybrid Lamborghini leaves us breathless: more than 1,000 HP of power.
Write down the name because it will be the least impressive: LB744. It is Lamborghini’s first plug-in hybrid, with four motors (one combustion and three electric) that achieve a combined power of 1,000 hp and, as a world-first, four-wheel drive in electric mode.
Lamborghini has revealed the first details of the LB744, its first HPEV (High-Performance Electrified Vehicle) hybrid supercar.
For the LB744, the Italian manufacturer has developed a new architecture with a new propulsion system that offers more than 1,000 hp.
The main ingredients in this recipe are a mid-mounted, naturally aspirated 6.5-liter V12 engine and three electrics, one of which is integrated into the gearbox (eight-speed dual-clutch).
The first plug-in hybrid Lamborghini
The first time an electric motor was coupled to a 12-cylinder internal combustion engine in a Lambo was in 2019 with the Sián, which produced a 25 kW electric motor to support the previous generation V12, storing the electrical energy in a supercapacitor.
The V12 engine is a classic in the Italian house since it debuted in the iconic Lamborghini 3650 GT (1963). In the LB744 it has been improved to become “the lightest and most powerful ever made by Lamborghini” (in total it weighs only 218 kilograms).
Mounted on Lamborghini’s plug-in hybrid, the engine delivers 825PS at 9,250rpm thanks to a redesigned timing system that supports a maximum rev range of 9,500rpm. The specific power is 128 hp per liter, the highest in the history of Lamborghini 12-cylinder engines, while the maximum torque is 725 Nm at 6,750 rpm.
Electric all-wheel drive
The powerful V12 engine of the Lamborghini LB744 is coupled to the front axle, as are two of the three electric motors, each of which provides drive to one of the front wheels.
The third electric motor sits atop the eight-speed dual-clutch gearbox that can supply power to the rear wheels, depending on the selected drive mode and conditions.
In this way, the plug-in hybrid supercar achieves a torque of 725 Nm produced by the internal combustion engine and 350 Nm by each of the front electric motors. In total, the power unit offers a maximum combined power of 1,015 hp.
The LB744 is a front-wheel drive only to optimize power consumption when in electric mode, while the rear-axle electric drive is activated on demand when needed.
The electric motors are powered by a specific high-power lithium-ion battery pack (4,500 W/kg) protected by a lower structural layer and connected to the front electric motors, the rear electric motor, and an integrated recharging unit.
The Lamborghini plug-in hybrid’s battery measures 1,550 mm long, 301 mm high, and 240 mm wide and is made up of bag cells with a total capacity of 3.8 kWh.
When the charge reaches zero, it can be recharged using domestic alternating current and charging column current of up to 7 kW of power, which allows the battery to be fully recharged in just 30 minutes. It can also be recharged through regenerative braking of the front wheels or directly from the V12 engine in just six minutes.
Lamborghini has not announced the vehicle’s acceleration figures or its top speed but they will surely significantly exceed those of the Aventador, the model it will replace when it goes on sale.
