Lamborghini Revuelto: the replacement for the Aventador is a hybrid and has more than 1,000 horses

The Lamborghini Revuelto combines a 6.5-liter naturally aspirated V12 engine with three electric motors, one of which is integrated into an eight-speed dual-clutch transmission. The other two act on the front axle.

Called the new electrified V12 L545 engine and from Sant’Agata in Bologna, they claim it is the lightest and most powerful 12-cylinder engine ever created.

Combined with the action of the three electric motors, the LB744’s control delivers a whopping 1,015 rpm.

The gasoline engine is responsible for 825 horsepower and 725 Newton meters, which are combined with another 700 Newton meters that come from two electric motors at the front end -350 each. The third electric motor generates 150 Newton meters with 150 horsepower.

The naturally aspirated V12 is 17 kilograms lighter than the Aventador and also adopts a new arrangement for the cylinders, which are tilted 180 degrees for 60 degrees.

The gasoline engine is connected to the rear axle, but the LB744 drives four wheels thanks to two electric motors acting on the front wheels. A third electric motor, integrated into the transmission, can also deliver power to the rear wheels. This means that this car can have a 4X4 in fully electric mode.

The LB744 battery has a capacity of 3.8 kilowatt hours and is integrated into the central tunnel. It measures 1.55 meters long by 0.30 high and 0.24 wide.

The eight-speed dual-clutch transmission fits longitudinally behind the V12 engine to free up space in the center tunnel for the battery. It is the third Lamborghini to adopt this transmission arrangement, after the Miura and Essentia SCV12. The opposite gear is completely electric.

Lamborghini has confirmed that the Revuelto 13 will have different driving modes with electronic torque vectoring. To the four conventional modes – Città, Strada, Sport, Corsa- three electric power management modes – Charging, Hybrid, Performance- are added, plus a custom mode, so the total is 13.

The Lamborghini Revuelto is a monocoque made of carbon fiber, with a composite front structure. According to the report, they anticipate the first supercar to have a front structure made entirely of carbon. In the case of the Ultimate Aventador, for reference, the material used was aluminum. Aluminum is used in the rear section of the chassis.

This makes the chassis 10% lighter than the Aventador. If we look only at the front structure, the change from aluminum to carbon fiber allows a greater reduction, 20% to be exact. This simultaneously increases the torsional stiffness by 25%. This weight reduction is especially important when the Revuelto deals with batteries and three electric motors. Any marginal gains on other fronts help to offset, at least in part, the weight derived from the incorporation of these systems.
