In the marque's 60th anniversary year, Automobili Lamborghini presented Revuelto, the first super sports V12 hybrid plug-in HPEV (High Performance Electrified Vehicle). Lamborghini 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.
"The new Revuelto is a milestone in the history of Lamborghini, and an important pillar in our Direzione Cor Tauri electrification strategy," said Stephan Winkelmann, Lamborghini Chairman and CEO. 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."
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 Lamborghini 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.
"With Revuelto we take the experience of driving a Lamborghini to a superior level," said Rouven Mohr, Lamborghini Chief Technical Officer. "Revuelto takes a significant step forward in terms of reactivity and responsiveness to ensure the most emotive and natural driving in every environment. Revuelto is a car delivering the highest performance but our objective right from the start was to confirm it at the very summit of driving emotions."
Design
Lamborghini Revuelto brings the future of Lamborghini design to the road today. It stays constant to the exclusive Lamborghini design DNA but establishes an entirely new stylistic language. It links with the iconic and legendary Lamborghini V12 cars of the past throughout the new shape, while the new proportions open the door towards the future.
While Lamborghini Revuelto delivers a quantum leap in an all-new car design, both externally and internally, the inspiration of previous V12 legends is still clear. Starting with the 1971 Countach prototype and its perfect proportions developed on a single longitudinal line, this car was responsible for creating a pure and essential style contextualized in the Space Age era. It defined the Lamborghini V12 super sports car DNA and introduced one of the most distinctive Lamborghini V12 elements: the vertically-opening scissor doors, which contribute to creating the character of Revuelto.
The new car also defers to the inimitable proportions of the Diablo and the floating blade on the rear fender, while the muscularity and inclined front of the Murciélago is evident.
"The Revuelto is adrenaline made visible," says Mitja Borkert, Lamborghini Head of Design. "The design of the new Lamborghini Revuelto opensa fascinating door towards the future of our uniquedesignlanguage.From first sight, Revuelto is an intriguing next-generation Lamborghini V12, with alllines embracingthe monocoqueandcelebrating a free view towards the V12 HPEV powertrain.
"The unique and recognizableY-shapelight signatureis significant in thisnewera ofour most iconicflagshipcar, and the interior is adramaticleap forward in defining the new design direction of Lamborghini. Our philosophy of "feel like a pilot" is vivid and visible in every detail:the driver and passengeraredeeply integrated in the very lightweight Y-shape design of dashboard and center console,replicating the sensations of being in a race car but with a perfectintuitivebalance between digital and physicalcontrols."
With the Revuelto, Lamborghini launches a new Space Race, ushering in a design language that adapts to the challenges imposed by electrification, and presaging the shapes and proportions of super sports cars of the near future. The design is inspired by aerospace elements, characterized by sculpted surfaces encompassed by two lines that start from the front and embrace the cabin and engine, tapering down to the hexagonal-shaped exhausts.
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 rear is a tribute to the hybrid V12. The fully-exposed longitudinal engine highlights the mechanical heart of the Revuelto, visually connecting it to the double hexagonal exhaust surmounted by the geometrically profiled wing, framed by headlamp clusters with the Y-shape light signatures.
The "Y" is also the hallmark of the driver-oriented interior design influenced by the "feel like a pilot" philosophy. The interior mirrors the all-new futuristic design of the exterior: every aspect of the cockpit is clearly Lamborghini, combining a perfect balance between a digital and physical experience both in daily driving and track environments. The visual center of the cabin houses a pronounced carbon-fiber profile, with a "space-ship" design that encloses the central air vents and the 8.4" vertical touchscreen, the technological heart of the car.
With Revuelto Lamborghini initiates a new immersive, shared driving experience, where pilot and co-pilot can simultaneously view the same information on the displays located in the 12.3" digital cockpit on the driver's side and on the 9.1" display installed on the passenger-side dashboard. Revuelto introduces the "swipe" function in a Lamborghini, allowing the pilot and co-pilot to move applications and information from the central display to the side displays with the same intuitive, gestural ease as using a smartphone. The three digital screens not only respond to the need for stylistic cleanness that enabled most of the physical buttons to be eliminated, but implement new features that allow the driver to concentrate fully on driving, just as in a race car.
The steering wheel was inspired by the racing world and the experience of the Essenza SCV12. The four rotors located on the spokes are used for selecting both the driving modes and the car's lifting system and rear wing tilt. The intuitive design of the cockpit and controls deliver a distinctive Lamborghini feeling: buttons are used to activate the turn signals and the launch control among other functions, while allowing the driver to maintain an optimal grip on the steering wheel at all times.
The Lamborghini Revuelto juxtaposes its personality as a track-inspired super sports car with a character designed for everyday driving with exceptional functionality. Significant attention was given in the design stages to ensure the cabin is roomy and practical as well as perfectly equipped for track-day outings. The roof design offers 26 mm more headroom than the Aventador Ultimae, while the new monofuselage provides 84 mm more legroom, leaving additional space behind the seats to accommodate luggage up to the size of a golf bag. This space is in addition to the compartment under the front hood, which can hold two cabin trolleys. Moreover, to make life on board even more comfortable, functional elements such as storage compartments located under the center dashboard and between the two seats have been included, as well as a cup holder built into the passenger-side dashboard.
Personalization
Lamborghini Revuelto is the production Lamborghini model that offers the most potential for personalization. In fact, 400 bodywork colors are offered together with many more personalization options at the client's disposal allowing the creation of an entirely individual super sports car. The sustainable sportiness of Revuelto does not stop at the technical specification of the plug-in hybrid: all the paints used are water based rather than solvent based.
'Sustainability' continues throughout the car's interior, reflecting the company's attention to avoiding waste that has become the modus operandi of the Lamborghini universe. This includes upholstery materials, cut in the Lamborghini 'selleria' utilizing latest-generation machinery: this limits waste as much as possible without affecting the craftmanship and embroidery processes, in which 'hand-made' continues as a point of excellence within Lamborghini.
The cabin is characterized by the presence of visible carbon fiber used on the dashboard, in the hexagonal air vents and to frame the dashboard and central vents. The upholstery combines fine leathers with the new ultralight Corsa-Tex fabric in Dinamica® microfiber, made of recycled polyester via a water-based production process. The customer can customize the interior of his car by opting for a balanced mix of leather and Corsa-Tex, or favor one material depending on his preference, with 70 color options available.
Aerodynamics
Function and style share a singular mission on the Lamborghini Revuelto: aerodynamic efficiency. The new layout of the super sports car has different design requirements compared to the Aventador, which influenced the car's aerodynamic development. The development was based on four pillars: efficiency; synergy between the components; integration between the components; and design.
Optimum efficiency was achieved by combining high downforce and minimized drag. One of the key elements in this strategy is the new active rear wing, created to ensure the best aerodynamic performance in all driving conditions. For this reason, entirely new actuators have been developed, managing the load optimally in every situation thanks to three different settings.
The position of the wing changes according to the driving mode and dynamics, or it can be changed manually by the driver according to his or her preferences using the dedicated rotor on the steering wheel. The "closed" position (low drag) ensures minimum resistance, for example when driving in electric mode. This position is also the most suitable for fuel economy. It improves top speed values while still ensuring stability. The "high downforce position" on the other hand, maximizes downforce by optimizing the agility and handling of the Revuelto.
The front section of the new super sports car from Sant'Agata is distinguished by a carbon fiber splitter with a radial leading edge in the central part and slanted in the lateral part, generating vortices that increase frontal load and deflect the air, avoiding the wheels. The central area has a shape that channels the flow to four rear vortex generators, consisting of narrow curved blades positioned in the underbody that are essential for increasing the energy of the airflow that strikes the car at the bottom. This, in turn, generates additional downforce and directs the airflow toward the diffuser, which has never been so extreme in a V12. The diffuser performs aerodynamic functions by extracting the incoming flow from the underbody via a differentiated channeling system between the central part with low slant (11° vs. the 7° of the Aventador Ultimae) and the lateral part with high slant (15° vs. 8° of the Aventador Ultimae). The diffuser also performs a structural and cooling function for the engine compartment.
In summary, the new design approach enabled the Lamborghini Revuelto to increase the front aerodynamic load by 33% and the rear load by 74% compared to the Aventador Ultimae (under maximum load conditions).
The synergy between components is evident in the focus placed on the cooling pattern that distinguishes the new Lamborghini Revuelto. The front radiator generates hot air that must be managed in the correct way so as not to impair the performance of the side radiators. Outward-facing louvers on the front radiator outlet grille direct the flow of hot air away from the wheel and away from the side radiators, while fins located on either side of the front bumper reduce aerodynamic drag.
All the elements have been designed and engineered to optimize airflow. Even the door handles perform an aerodynamic function thanks to the Y-section wing profile: a solution that allows them to divert the flow of fresh air they receive from the front hood to one of the horizontal fins located along the side, directing it toward the radiator.
The maximum integration between the components is evident in the cooling pattern of the brake system, where aerodynamics becomes part of the system. The pair of front suspension deflectors and the grille inside the wheel arches are designed to improve not only the cooling of the front brakes - the deflectors draw air from the front diffuser and channel it to the brake - but they are shaped to reduce resistance inside the wheel well, limiting any compression phenomena while increasing the load at the front.
At the rear end, the two NACA ducts located in front of the rear wheels collect flow from the underbody and direct it to the rear brake cooling duct.
The carbon fiber roof also plays an important aerodynamic role with a structural function that improves interior roominess. The wing profile design with a hollowed-out central part directs air to the rear air intakes, and consequently to the inverter and electric motor located on the gearbox, while the roof's side volumes provide more headroom for both driver and passenger.
Monofusolage
The Lamborghini Revuelto is based on a new aeronautics-inspired chassis, the 'monofuselage'. As well as a monocoque made entirely of multi-technology carbon fiber, it features a front structure in Forged Composites; a special material made of short carbon fibers soaked in resin. This technology was developed and used by Lamborghini in its first structural applications as far back as 2008.
The monofuselage represents a significant step forward from the Aventador in terms of torsional stiffness, lightweight qualities and driving dynamics. What's more, the Revuelto is the first super sports car to be fitted with a 100% carbon fiber front structure: carbon fiber is also used for the front cone structures to ensure a level of energy absorption that is significantly higher when compared to a traditional metal structure - double that of the Aventador's aluminium front frame - combined with a substantial reduction in weight.
Powertrain and Layout
The car showcases an unprecedented layout and powertrain: the naturally-aspirated 6.5-liter 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 Lamborghini Revuelto into a purely electric car, reducing overall CO2 emissions by 30% 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 Lamborghini 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.
The air intake ducts to the cylinders have been re-engineered to increase the supply of air and guarantee optimal airflow in the combustion chamber. The combustion within the actual engine has also been optimized, thanks to the regulation of ionization in the chamber with two control units: a solution already used in the Aventador and now transferred to the new model. The new combustion system is also characterized by an increased compression ratio (12.6:1 compared to 11.8:1 for the Aventador Ultimae). The fluid dynamics of the exhaust have also been improved to reduce counter-pressure at high revs and increase the specific power output.
From the very beginning, Lamborghini cars were famed for their uniquely emotional and unmistakable sound. Particular attention has been lavished on the 'soundtrack' of the new L545 to emphasize the tone of the engine, already melodious at low revs and then rising to a natural harmonious crescendo.
Electric four-wheel drive
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.
Getting into gear
The adoption of a new platform has prompted innovative technical decisions involving the gearbox: the nerve center of the hybrid plug-in unit. The adoption of a new platform has delivered innovative technical decisions involving the gearbox: the nerve center of the hybrid plug-in unit. To achieve its goals, a new compact transmission unit was developed, able to meet the needs of such a potent electric power unit and following Revuelto will go on to equip the next generation of super sports cars from Sant'Agata Bolognese. Incorporation of a wet double clutch as the most efficient and performance-oriented solution, ensures optimum management of the 725 Nm of torque at 6750 rpm from Lamborghini Revuelto's internal combustion engine.
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.
In the 60-year history of Lamborghini, only two other V12 cars have been equipped with a transverse rear gearbox: the revolutionary Miura launched in 1966, which also adopted a mid-rear transverse engine layout; and the Essenza SCV12, a track-focused hypercar with a longitudinal engine and load-bearing transverse gearbox.
The internal structure of the new gearbox has two distinct shafts as opposed to the usual three. One manages the even-numbered gears, the other manages the odd numbers. Both engage the same rotor. This layout helps to keep down the overall weight while also saving space.
The development of an eight-speed Double Clutch Transmission (DCT) comes from the desire to create a unit that provides everything needed for sporty driving such as fast gear shifts, while the inclusion of an eighth ratio helps optimize fuel consumption and drivability while cruising.
A particular feature is the 'continuous downshifting', which drops down multiple gears under braking simply by holding down the left paddle, giving the driver the feeling of total control.
