Lamborghini has released the first technical info concerning the new 12-cylinder supercar LB744 that will be soon unveiled integrally. The first super-sports hybrid plug-in V12 HPEV (High Performance Electrified Vehicle) will be then ready to make its debut in the year of the brand’s 60th anniversary. The car’s goal is defining a new paradigm in terms of performances, sport character and drive pleasure, also thanks to a new architecture and a powertrain exceeding 1000 HP, combining the power of a brand-new thermal motor with three electric motors and the first dual-clutch gearbox that makes its debut on a 12-cylinder Lamborghini.
Compared to the previous powertrain, V12 has been rotated by 180° and is no longer equipped with the transmission in the front part but instead downstream the engine block, connected with the only rear wheels. The physical transmission shaft is replaced by the lithium 3.8 kWh battery that powers the electrified front axis, rechargeable at 7 kW, taking around half an hour to fill up.
The overall weight is 193 Kg, which includes the integration of a new fundamental component in the vehicle’s hybrid architecture, the rear e-motor, which has a maximum power of 110 kW and maximum torque of 150 Nm.
Placed above the gearbox, the electric unit performs the tasks of starter and generator, besides supplying energy to the two front electric motors through the battery positioned under the tunnel, acting as boost in the full electric drive modality and allowing the zero-emission four-wheel drive, directly acting on the rear axle. The tasks vary depending on the drive modality inserted, through an uncoupling mechanism. For that reason, it is equipped with dedicated synchronizer, which allows the connection to the double-clutch gearbox. When it supports the action of the V12, the e-motor is in the position that is defined P3, with electric motor downstream the gearbox, whereas it shifts to P2 to recharge the battery when stationary or at low speeds and it acts also as starter motor.
Electric powertrains improve the power delivery at low revolutions and can also make the new LB744 a fully electric-traction car, reducing the overall CO2 emissions by 30% versus the Aventador Ultimae.
