The pack is much lighter than most batteries, weighing 70kg, with the front motors adding another 80kg of mass. Fuel economy and CO2 figures haven’t been finalised, but Lamborghini says both will be around 30% better than the Aventador Ultimae’s.
The battery’s peak flow rate is the limiting factor on electrical assistance, with a maximum of 140kW equating to 187bhp. Each of the three motors can take up to 147bhp, allowing the battery’s output to be juggled accordingly – and with torque biasing across the front axle.
The rear electric motor adds assistance to one shaft in the dual-clutch gearbox, meaning it is possible for the two sides of the Revuelto’s powertrain to be driving different gears simultaneously.
Like the Lamborghini Sián FKP 37 and Countach LPI 800-4 hyper-hybrids, as well as the Ferrari SF90, the Revuelto will reverse under electrical power only, but has the ability to drive all four wheels.
The Revuelto will be heavier than the Aventador, despite weight savings throughout the structure. The new car’s carbonfibre tub is both lighter and 40% stiffer than the last generation’s and now features a composite front crash structure – a world first in a road car.
But the bulk of the hybrid system means that overall mass is still higher. Lamborghini hasn’t released a formal kerb weight, but the promise of a power-to-weight ratio of 563bhp per tonne puts it at 1776kg.
