With the world operating headlong into an EV future, whether or not or not it’s with totally electrical propulsion or hybrid tech, most producers have needed to develop shortly to catch up. Whereas consumer-based manufacturers like Toyota, Ford, and Volkswagen have been on the forefront of this, even unique efficiency producers like Ferrari and Lamborghini have needed to undertake the growing automotive development to maintain their specialist creations authorized.
Many immensely highly effective hybrid autos are round lately, particularly a few of the plug-in hybrid ones. Simply take into consideration the truth that a Mercedes-AMG C63 S E Efficiency has a staggering 671 hp on faucet – and that solely comes with a 2.0L turbocharged fuel engine! CarBuzz determined to trace down the plug-in hybrid with the most important inner combustion engine of all of them.
Each plug-in hybrid car was thought of for this text, with the winner being the instance with the most important inner combustion engine.
The Lamborghini Revuelto Guidelines The Hybrid Engine Measurement Roost
The winner of this specific contest is the Lamborghini Revuelto, the Italian marque’s flagship supercar. The Revuelto was first proven off in 2023 because the much-anticipated successor to the Aventador, which had acted as Lamborghini’s halo automobile for over a decade. Wanting to maintain followers and consumers on aspect, Lambo determined to develop a brand new model of its howling naturally aspirated 6.5-liter V12 engine, moderately than ditch it for some type of twin-turbo V8, which tends to lack the drama of a mighty V12.
This was welcomed by gearheads all over the place, given the model mothballed the naturally aspirated V10 used within the Huracán and developed a twin-turbo V8 for its successor, the Temerario. To verify it might meet environmental legal guidelines all over the world, the Revuelto’s V12 was mated to a trio of high-powered electrical motors, making it the second of its kind provided by Lambo after the 2019 Sián FKP 37.
The Revuelto Is Considerably Higher For The Surroundings Than Its Predecessor
Implementing a plug-in hybrid system alongside the V12 made an enormous distinction when it comes to emissions, with the Revuelto’s emissions being 25% decrease than the Aventador. This does not imply it is some neutered automobile that’s higher suited to pootling to the outlets although, because the Revuelto nonetheless retains its livid bull vitality beneath the floor, and continues to be each inch a Lamborghini.
The Revuelto Pushes The Envelope On All Fronts
For a kick-off, the Revuelto solely has a 3.8-kWh battery, which is slotted between the 2 entrance seats. Its low capability means the automobile can solely journey for round 5 miles on pure EV energy, with the additional grunt as an alternative utilized to help the V12 to get the Revuelto up to the mark as shortly as doable. The 6.5-liter V12 brings 814 hp to the social gathering by itself, whereas the three electrical motors present an additional 187 hp for a complete of 1,001 hp. The V12 brings 535 lb-ft by itself (a mixed determine will not be offered), which is channeled between the 4 wheels.

To assist enhance weight distribution, two of the electrical motors are positioned on the entrance axle, whereas the third is mounted behind the V12 towards the rear of the automobile. To raised unify the engine with the motors, the V12 was rotated by 180 levels in comparison with the way it was within the Aventador. The powerplant was additionally handled to a spread of upgrades to enhance its effectivity and energy output.
These embrace a brand new exhaust system that reduces again strain at greater revs, a revised valvetrain, a brand new consumption association, in addition to a extra environment friendly combustion course of. Lamborghini’s engineers additionally managed to cut back the V12’s whole weight by round 74 kilos in comparison with the unit used within the Aventador. Its eight-speed dual-clutch automated transmission can be new, the unit positioned transversely behind the engine to unencumber area for the battery. That is the primary time Lamborghini has used this gearbox structure for the reason that Miura within the Nineteen Sixties. It may be set to make use of the engine with out the battery, permitting it to retain further cost, and regenerative braking recharges the battery.
The Revuelto Comes With A Newly Developed Carbon-Fiber Monocoque
Lambo’s high canine additionally will get a revolutionary new monocoque design, which stretches additional ahead than most different examples. Often known as the ‘monofuselage’, the design originating from aeronautics, it is 10% lighter than the monocoque featured within the Aventador, in addition to being 25% stiffer. This not solely helps to make the car extra responsive, but it surely’s additionally safer within the occasion of a crash. Moreover, the Revuelto is the primary Lamborghini with torque vectoring, which helps to make driving extra pleasurable. The model’s LDVI 2.0 system can handle the torque on every wheel relying on the terrain it is traversing, and it may possibly even predict how the wheels will behave, permitting it to adapt shortly. This enhances traction and cornering grip considerably, it doesn’t matter what type of street you are attacking.
The Hybrid System Is Tuned To Improve Efficiency, Moderately Than Effectivity
In most traditional plug-in hybrids, the battery is designed to be sufficiently big to care for metropolis driving on pure EV energy to cut back CO2 emissions in busy areas, with the engine kicking in on quicker roads to extend energy and vary. The Revuelto’s five-mile EV vary would not present a lot assist in the town although, because the engine will quickly must kick in once more.
The automobile was designed this manner, as Lambo would not actually care about giving the Revuelto an extended electrical vary, and neither ought to it. The hybrid system is tuned to work with the V12 to enhance efficiency. Not solely does it add further energy and torque to the combo, but it surely makes use of this energy to even out the ICE’s energy and torque curves. This prevents any lack of energy at low revs or throughout shifts, making certain acceleration is perfect from the underside to the highest of the rev vary.
A useful byproduct of that is that the V12 wants to make use of much less gas, as {the electrical} vitality ensures it would not must work fairly so arduous to extend the car’s pace. This implies you may go quicker whereas saving some valuable fuel, so it is a win-win all spherical. That stated, its fuel mileage is only one mpg higher than that of the Aventador on the EPA’s three cycles, with the mixed determine sitting at 17 mpg.

Whereas the Revuelto at the moment has the most important engine of any plug-in hybrid car, the upcoming Bugatti Tourbillon is ready to grab away the initiative. The Tourbillon will turn out to be the primary hybrid Bugatti mannequin ever provided, with its big naturally aspirated 8.3-liter V16 powerplant being mated to a trio of electrical motors. Like on the Lamborghini, two will likely be mounted on the entrance axle, with the third on the rear.
The similarities proceed with the drivetrain, with the Bugatti getting an eight-speed dual-clutch auto transmission, whereas the all-wheel-drive system will likely be able to making use of torque vectoring. The a lot bigger engine will convey a ton extra grunt although, with the Tourbillon coming with a complete of 1,775 hp. It additionally comes with a bigger 25-kWh battery pack, that means it will be capable to journey 37 miles on pure EV energy. With the $4 million mannequin set for launch someday in 2026, the Lamborghini ought to take pleasure in its time on the high of the engine-size pyramid for PHEVs.
