Automobili Lamborghini has unveiled the Revuelto, 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 new architecture; innovative design; maximum-efficiency aerodynamics; and a new carbon frame concept. An output of 1015 CV (1001 HP) 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.
“The new Revuelto is a milestone in the history of Lamborghini, and an important pillar in our Direzione Cor Tauri electrification strategy. It is a unique and innovative car but at the same time faithful to our DNA: the V12 is an iconic symbol of our super sports heritage and history. Revuelto was born to break the mold, combining a new 12-cylinder engine with hybrid technology, creating the perfect balance between delivering the emotion that our clients want with the necessity to reduce emissions.” – Stephan Winkelmann, Lamborghini Chairman and CEO
Carbon fiber, produced via artisan craftmanship in the Sant’Agata Bolognese factory, is the principal structural element within the new car, used not only in the monofuselage and frame but also for many elements of the bodywork. The extensive use of carbon fiber and lightweight materials, combined with the potent engine power, contributes to achieving the best weight-to-power ratio in the history of Lamborghini: 1.75 kg/CV.
The new Revuelto combines these attributes to deliver performance figures at the peak of its segment: acceleration from 0-100 km/h in only 2.5 seconds and a top speed of more than 350 km/h. These numbers combine with its exceptional dynamism thanks to the introduction of electric torque vectoring, and four-wheel drive available also in fully-electric drive mode, ensuring the Revuelto super sports car expresses its amplified qualities both on track and in daily driving.
The aerospace elements blend harmoniously with an animalistic muscularity starting at the front: the shark-nose section modeling of the broad monolithic carbon-fiber hood conveys a sense of power and speed. This is matched by the headlamp clusters with Y-shape daytime running lights – a distinctive stylistic feature of contemporary Lamborghini design – framed by aerodynamic blades that connect the splitter to the hood itself. The side fins, located behind the front wheel arches, channel the airflow along the sides and the pronounced concavities of the doors to the side air intakes, which feature sharp edges that echo the arrows on the front.
The roof combines more headroom with aesthetic qualities and specific aerodynamic functions. The recessed profile channels air to the rear wing but at the same time allows more headroom in the cabin for both the driver and passenger.
The Revuelto retains one of Lamborghini’s strongest traditions: four-wheel drive. As well as the internal combustion engine that provides power to the rear wheels, a pair of electric motors now make their debut on the front axle, each supplying traction to one of the front wheels. There’s also a third electric motor positioned above the eight-speed double-clutch gearbox that can supply power to the rear wheels, depending on the selected driving mode and the conditions.
The combined torque from the combustion engine and three electric motors offers performance levels that are unique even within the domain of super sports cars, with 725 Nm produced by the internal combustion engine and 350 Nm from each of the front electric motors. In total, the power unit delivers a combined maximum output of 1015 CV.
The two electric motors at the front are oil-cooled axial flux units and offer an exceptional weight-to-power ratio: 18.5 kilograms from each of the 110 kW units. As well as providing power to the front wheels, they also have a torque vectoring function, optimizing driving dynamics, and recuperating the energy produced under braking. When in electric mode, the Revuelto is front-wheel drive only to optimize energy consumption, while electric drive to the rear axle is activated on demand when needed.
The Lamborghini Revuelto is equipped with a lithium-ion high specific power (4500 W/kg) battery pack situated within the central tunnel, keeping the center of gravity as low as possible and ensuring optimal weight distribution. The battery is protected by a lower structural layer and is connected to the front electric motors, the rear electric motor, and an integrated recharging unit.
The battery is 1550mm long, 301mm high, and 240mm wide, containing pouch cells with an overall capacity of 3.8 kWh. When the charge drops down to zero it can be recharged using both ordinary domestic alternating and charging column current up to 7 kW in power, and completely recharges in just 30 minutes. It can also be recharged under regenerative braking from the front wheels or directly from the V12 engine in just six minutes.
The new eight-speed gearbox is positioned transversally behind the longitudinal V12 engine, to leave space in the tunnel for the lithium-ion battery that feeds the electric motors. It’s a technical solution that’s unique in the world of high-performance cars, and places Lamborghini once more at the cutting-edge of automotive engineering. The layout helps to keep the car’s wheelbase contained and supports effective weight distribution for the best driving dynamics.
The double-clutch gearbox is extremely compact; just 560mm long, 750mm wide and 580mm high. Total weight is just 193 kg, which includes a new component fundamental to the car’s hybrid architecture: the rear electric motor, with maximum power of 110kW and peak torque of 150Nm.
Located above the gearbox, this electric motor doubles as the starter motor and generator, as well as supplying energy to the front electric motors via the battery in the transmission tunnel. In full electric mode it can also provide power to the rear wheels that, in addition to the e-motors driving the front wheels, allows electric four-wheel drive. How the system functions depends on which driving mode is engaged, thanks to an uncoupling mechanism with a dedicated synchronizer allowing the connection to the double-clutch gearbox. When it is providing additional power to the V12 internal combustion engine, the electric motor is in P3 position, separated from the gearbox, while it moves into the P2 position to recharge the battery at low speeds and when parked, also serving a starter motor.
In the P3 position, the Revuelto can become an electric four-wheel drive car, depending on the drive mode selected, continuing Lamborghini’s four-wheel drive tradition even in electric mode.
Reverse gear is provided by the two front electric motors, although if extra momentum is needed the rear electric motor can also kick in, which activates the rear axle and wheels. As a result, the Revuelto can drive all four wheels in electric mode even when reversing in low grip conditions.
