Automobili Lamborghini has unveiled the Revuelto, the primary tremendous sports activities V12 hybrid plug-in HPEV (Excessive Efficiency Electrified Automobile). Revuelto defines a brand new paradigm by way of efficiency, sportiness and driving pleasure from its new structure; progressive design; maximum-efficiency aerodynamics; and a brand new carbon body idea. An output of 1015 CV (1001 HP) is delivered from the mixed energy of a wholly new combustion engine along with three electrical motors, alongside a double-clutch gearbox that makes its debut on a 12-cylinder Lamborghini for the primary time.
The powertrain combines excessive particular energy components: the brand new 127 CV/liter combustion engine works synergically with two entrance axial flux motors that ship an impressive weight-to-power ratio, with a radial flux electrical motor positioned above the primary eight-speed double-clutch gearbox debuting on a 12-cylinder Lamborghini. The three electrical motors are powered by a lithium-ion excessive particular energy (4500 W/kg) battery pack that additionally helps a fully-electric drive mode.
“The brand new Revuelto is a milestone within the historical past of Lamborghini, and an necessary pillar in our Direzione Cor Tauri electrification technique. It’s a distinctive and progressive automobile however on the identical time trustworthy to our DNA: the V12 is an iconic image of our tremendous sports activities heritage and historical past. Revuelto was born to interrupt the mould, combining a brand new 12-cylinder engine with hybrid expertise, creating the proper steadiness between delivering the emotion that our shoppers need with the need to cut back emissions.” – Stephan Winkelmann, Lamborghini Chairman and CEO
Carbon fiber, produced by way of artisan craftmanship within the Sant’Agata Bolognese manufacturing unit, is the principal structural component throughout the new automobile, used not solely within the monofuselage and body but in addition for a lot of components of the bodywork. The intensive use of carbon fiber and light-weight supplies, mixed with the potent engine energy, contributes to attaining one of the best weight-to-power ratio within the historical past of Lamborghini: 1.75 kg/CV.
The brand new Revuelto combines these attributes to ship efficiency figures on the peak of its phase: acceleration from Zero-100 km/h in solely 2.5 seconds and a high velocity of greater than 350 km/h. These numbers mix with its distinctive dynamism due to the introduction of electrical torque vectoring, and four-wheel drive accessible additionally in fully-electric drive mode, making certain the Revuelto tremendous sports activities automobile expresses its amplified qualities each on observe and in every day driving.
The aerospace components mix harmoniously with an animalistic muscularity beginning on the entrance: the shark-nose part modeling of the broad monolithic carbon-fiber hood conveys a way of energy and velocity. That is matched by the headlamp clusters with Y-shape daytime working lights – a particular stylistic characteristic of up to date Lamborghini design – framed by aerodynamic blades that join the splitter to the hood itself. The aspect fins, positioned behind the entrance wheel arches, channel the airflow alongside the edges and the pronounced concavities of the doorways to the aspect air intakes, which characteristic sharp edges that echo the arrows on the entrance.
The roof combines extra headroom with aesthetic qualities and particular aerodynamic features. The recessed profile channels air to the rear wing however on the identical time permits extra headroom within the cabin for each the driving force and passenger.
The Revuelto retains one in all Lamborghini’s strongest traditions: four-wheel drive. In addition to the inner combustion engine that gives energy to the rear wheels, a pair of electrical motors now make their debut on the entrance axle, every supplying traction to one of many entrance wheels. There’s additionally a 3rd electrical motor positioned above the eight-speed double-clutch gearbox that may provide energy to the rear wheels, relying on the chosen driving mode and the situations.
The mixed torque from the combustion engine and three electrical motors affords efficiency ranges which might be distinctive even throughout the area of tremendous sports activities automobiles, with 725 Nm produced by the inner combustion engine and 350 Nm from every of the entrance electrical motors. In whole, the ability unit delivers a mixed most output of 1015 CV.
The 2 electrical motors on the entrance are oil-cooled axial flux models and provide an distinctive weight-to-power ratio: 18.5 kilograms from every of the 110 kW models. In addition to offering energy to the entrance wheels, additionally they have a torque vectoring operate, optimizing driving dynamics, and recuperating the vitality produced below braking. When in electrical mode, the Revuelto is front-wheel drive solely to optimize vitality consumption, whereas electrical drive to the rear axle is activated on demand when wanted.
The Lamborghini Revuelto is provided with a lithium-ion excessive particular energy (4500 W/kg) battery pack located throughout the central tunnel, conserving the middle of gravity as little as doable and making certain optimum weight distribution. The battery is protected by a decrease structural layer and is related to the entrance electrical motors, the rear electrical motor, and an built-in recharging unit.
The battery is 1550mm lengthy, 301mm excessive, and 240mm vast, containing pouch cells with an total capability of three.eight kWh. When the cost drops right down to zero it may be recharged utilizing each unusual home alternating and charging column present as much as 7 kW in energy, and utterly recharges in simply 30 minutes. It will also be recharged below regenerative braking from the entrance wheels or immediately from the V12 engine in simply six minutes.
The brand new eight-speed gearbox is positioned transversally behind the longitudinal V12 engine, to go away area within the tunnel for the lithium-ion battery that feeds the electrical motors. It’s a technical resolution that’s distinctive on the earth of high-performance automobiles, and locations Lamborghini as soon as extra on the cutting-edge of automotive engineering. The structure helps to maintain the automobile’s wheelbase contained and helps efficient weight distribution for one of the best driving dynamics.
The double-clutch gearbox is extraordinarily compact; simply 560mm lengthy, 750mm vast and 580mm excessive. Complete weight is simply 193 kg, which features a new element basic to the automobile’s hybrid structure: the rear electrical motor, with most energy of 110kW and peak torque of 150Nm.
Positioned above the gearbox, this electrical motor doubles because the starter motor and generator, in addition to supplying vitality to the entrance electrical motors by way of the battery within the transmission tunnel. In full electrical mode it could possibly additionally present energy to the rear wheels that, along with the e-motors driving the entrance wheels, permits electrical four-wheel drive. How the system features is dependent upon which driving mode is engaged, due to an uncoupling mechanism with a devoted synchronizer permitting the connection to the double-clutch gearbox. When it’s offering further energy to the V12 inside combustion engine, the electrical motor is in P3 place, separated from the gearbox, whereas it strikes into the P2 place to recharge the battery at low speeds and when parked, additionally serving a starter motor.
Within the P3 place, the Revuelto can turn out to be an electrical four-wheel drive automobile, relying on the drive mode chosen, persevering with Lamborghini’s four-wheel drive custom even in electrical mode.
Reverse gear is supplied by the 2 entrance electrical motors, though if further momentum is required the rear electrical motor may kick in, which prompts the rear axle and wheels. Because of this, the Revuelto can drive all 4 wheels in electrical mode even when reversing in low grip situations.
