Lamborghini Revuelto: the first super sports V12 hybrid HPEV In the marque’s 60th anniversary year, Automobili Lamborghini presents Revuelto[1], the first super sports V12 hybrid plug-in HPEV (High Performance Electrified Vehicle). Revuelto defines a new paradigm in terms of performance, sportiness and driving pleasure from its unprecedented new architecture; innovative design; maximum-efficiency aerodynamics; and a new carbon frame concept. An output of 1015 CV is delivered from the combined power of an entirely new combustion engine together with three electric motors, alongside a double-clutch gearbox that makes its debut on a 12-cylinder Lamborghini for the first time. The powertrain combines high specific power elements: the new 127 CV/liter combustion engine works synergically with two front axial flux motors that deliver an outstanding weight-to-power ratio, with a radial flux electric motor positioned above the first eight-speed double-clutch gearbox debuting on a 12-cylinder Lamborghini. The three electric motors are powered by a lithium-ion high specific power (4500 W/kg) battery pack that also supports a fully-electric drive mode. Powertrain and Layout The car showcases an unprecedented layout and powertrain: the naturally-aspirated V12 mid-mounted engine is complemented by three electric motors, one of which is integrated into the new double-clutch eight-speed gearbox. This is mounted transversely and placed for the first time behind the combustion engine. In what has been the transmission tunnel since the days of the Countach, there is a lithium-ion battery instead, which powers the electric motors. The electric motors boost power delivery at low revs and can also turn the new Revuelto into a purely electric car, reducing overall CO2 emissions by 30%[2] compared to the Aventador Ultimae. A unique architecture Lamborghini has been synonymous with V12 engines since the company was founded. The very first Lamborghini model to sport this characteristic engine was the iconic 350GT launched in 1963. The first time that an electric motor was matched to a 12-cylinder internal combustion engine in a Lamborghini was in 2019 with the Sián, which used a 25 kW electric engine to support the previous generation of V12, storing the electrical energy in a supercapacitor. The Revuelto introduces an unprecedented hybrid architecture and a new generation of V12. The car is launched as the very first High Performance Electrified Vehicle - HPEV: a plug-in hybrid super sports car equipped with a lightweight high-power lithium ion battery, housed within the transmission tunnel in the central section of the chassis. It’s an innovative solution, designed to reduce emissions compared to the previous V12 while maximizing performance. The new L545 engine has a capacity of 6.5 liters and is the lightest and most powerful 12-cylinder engine ever made by Lamborghini. In total it weighs just 218 kilograms: 17 kilograms less than the Aventador unit. The Revuelto features the engine rotated through 180 degrees compared to the Aventador layout. The superquadro V12 puts out 825 CV at 9250 revs per minute thanks to the redesigned distribution system that supports a maximum rev range of 9500 rpm. Specific power is 127 CV per liter, the highest output in the history of Lamborghini’s 12-cylinder engines, while maximum torque is 725 Nm at 6750 rpm.
