Rumoured Lamborghini Aventador Replacement to Get 1,000HP Hybrid Drivetrain

One of the automotive industry’s worst-kept secrets, Lamborghini has confirmed that the Aventador’s rumoured successor, codenamed the ‘LB744’, will be powered by a Hybrid V12 producing 1015 CV (1000hp). Leaks, rumours, and spy videos shared online have all but revealed the car with plenty of Lamborghini styling, including plenty of ‘Y’ motifs and a large twin central exhaust system.

More details surrounding the 2024 Lamborghini Aventador replacement will arrive over the coming months, but we’ve had our best look yet at what could be powering the next-generation supercar.

It starts with a brand new 6.5-litre 12-cylinder internal combustion engine that’s mated to three electric motors and a ground-breaking wet double-clutch gearbox that makes its debut on the V12 Lamborghini (no more single-clutch neck snaps). Interestingly, this gearbox is mounted transversely and placed behind the combustion engine for the first time, making room for lithium-ion batteries inside the transmission tunnel.

The new L545 engine itself is an engineering masterpiece. It’s rotated 180 degrees compared to the Aventador, and while it might have a capacity of 6.5 litres, it weighs just 218kg (17kg less than the Aventador unit). The brand hasn’t shared how much the ‘LB744’ weighs, there’s still a good chance the overall weight of the car is significantly more than the Aventador, once you factor in batteries and electric motors.

It goes further, the engine alone produces more than 800HP and revs to 9500 rpm. Per cylinder outputs are marked at 126HP per litre, the highest output in the history of Lamborghini V12s. Maximum torque is 725 Nm at 6750 rpm.

Most importantly, the V12 sound will remain with Lamborghini paying specific attention to the ‘soundtrack’ of the new engine. Of course, emissions mean it won’t scream like an Aventador from a decade ago. However, we’d expect plenty of intake noise inside the cabin of a similar nature to the Huracan STO and even the Porsche GT4 RS. Lamborghini says the tone is “melodious” at low revs before “rising to a natural harmonious crescendo.”

As mentioned, the transmission tunnel now lays claim to the lithium-ion high specific power (4500 W/kg) battery pack that’s mounted low to retain the centre of gravity. The battery is connected to the front electric motors, the rear electric motor, and an integrated recharging unit while being protected by a lower structural layer. We find it interesting that the brand continues to refer to the ‘transmission tunnel’ as the home for the battery, certainly sounds like this could be a riff on the original Aventador chassis.

This won’t be a typical ‘plug-in hybrid’ like those from the prancing horse. That being said, you can indeed ‘plug it in’ although the battery itself has a very-small overall capacity of just 3.8 kWh. You can recharge the battery using both ordinary domestic alternating and charging column current up to 7 kW in power, this results in a complete recharge in 30 minutes. Regenerative braking is also possible through the front wheels or the V12 engine itself in 6 minutes.
