The new super sports car is in a league of its own: a 920 CV twin-turbo V8 hybrid powertrain offering the highest levels of performance and comfort for a peerless driving experience
Sant'Agata Bolognese/Monterey, California, 16 August 2024 â Automobili Lamborghini presents Temerario, the all-new super sports car equipped with a twin-turbo V8 hybrid powertrain that redefines the very concepts of performance, driving pleasure and comfort. The Temerario is the second model in the Lamborghini High Performance Electrified Vehicle (HPEV) range, after the Revuelto.
A star of Monterey Car Week 2024, the Temerario presents itself as the new benchmark in the super sports car segment, thanks to class-beating performance. The new hybrid powertrain combines an entirely new twin-turbo V8 engine with three electric motors, providing a total power output of 920 CV. The twin-turbo V8 has been designed and developed from scratch in SantâAgata Bolognese and is the first and only production super sports car engine able to reach 10,000 rpm. The performance is an absolute revelation: maximum speed of over 340 km/h (210+ mph), 0 to 100 km/h (0-62 mph) in just 2.7 seconds.
âThe Temerario is a genuine âfuoriclasseâ: a car in a league of its own, an extraordinary and innovative vehicle both from a technical and stylistic point of view,â says Stephan Winkelmann, Chairman and CEO of Automobili Lamborghini. âEvery new Lamborghini must surpass its forerunners in performance terms, while at the same time being more sustainable from an emissions standpoint. With the Temerario, we have completed a key chapter in the electrification strategy included in our Direzione Cor Tauri plan: we also become the first luxury automotive brand to offer a completely hybridized range.â
With the Temerario Lamborghini has also achieved new heights in terms of aerodynamic efficiency, combined with stylistic details and lines that represent a further landmark in the brand's design. Also entirely new is the aluminum chassis which, thanks to the use of a cutting-edge high-strength, ultra-light alloy, significantly increases torsional rigidity and contributes to excellent driving dynamics.
The chassis delivers excellent passenger comfort and increased roominess: the Temerario is a super sports car that expresses its full potential on the track while offering more space for passengers and luggage than any other vehicle in its segment.
The Temerario also delivers the most advanced multimedia experience in Lamborghini history, thanks to the introduction of the Lamborghini Vision Unit system, which provides access to new functions and applications that allow users to relive and share their track and road driving experiences.
POWERTRAIN
The heart of a Lamborghini has always been its drive system. With the new Temerario, Lamborghini takes an entirely new approach, with several years of development, delivering an unprecedented super sports car powertrain, comprised of an extremely high-revving biturbo Internal Combustion Engine concept combined with three electric motors. âWe wanted to develop an incomparable, high-performance sports engine that combines the best of two worlds: an emotional combustion engine based on a twin-turbocharged V8 and a performance-oriented electrification. Our concept of incorporating three electric motors with a combustion engine ensures to achieve instantaneous acceleration, torque vectoring and energy recuperation. With the Temerario we are redefining the segment,â says Rouven Mohr, Chief Technical Officer at Lamborghini. âTemerario is in a league of its own, in terms of engineering solutions and performance.â
The new powertrain is integral to the second super sports car in Lamborghini's High-Performance Electrified Vehicle (HPEV) product range. The first target was to achieve the highest possible power and torque, while at the same time offering the response of a classic high-revving naturally aspirated engine. Therefore, only high-performance components are used in the drivetrain: the new 4.0-liter V8 biturbo engine has a specific output of 200 CV per liter and works together with an oil-cooled axial flow electric motor fully integrated in the V8 housing. Propulsion is supported by two electric motors on the front axle.
âBy combining a high-revving V8 biturbo with three electric motors of axial flux type we are taking a very sophisticated approach that has never been seen before in series production and the result will impress Lamborghini fans all over the world - With this adrenaline-machine, we are catapulting ourselves into a new paradigm for super sports cars,â continues Mohr. This linearity and progression, with high revving characteristics, which was previously only possible with naturally aspirated engines, now offers high torque with high engine speeds, thanks to the turbochargers.
The new engine with the internal designation L411 is now one of the most powerful engines in the segment. The V8 biturbo delivers its peak power of 800 CV from 9,000 to 9,750 rpm and 730 Nm of torque between 4,000 and 7,000 rpm. The electric motor, in P1 position (between the V8 engine and the gearbox), ensures immediate response starting from low engine speed and continues consistently through gear shifts, working as a âtorque gap fillerâ and improving the transient response, giving the sensation of linear and limitless progression up to 10,000 revs. Thanks to the two large turbochargers, efficiency and performance are increased at top speeds. These are located compactly in the V of the engine as a âhot V8â to optimize the packaging and thermal management. The V8 biturbo can rev up to 10,000 revolutions per minute: the maximum boost pressure of the turbochargers is 2.5 bar (abs). The turbines are controlled with an electrical wastegate and a wheel-speed sensor. Lamborghini has designed air filter boxes with tubular cartridges, making them extremely compact to create space and become even more efficient.
At the heart of the crankshaft housing is a flat-plane crankshaft with a 180-degree angle between the crankshaft bends. This crankshaft, which is typically used in racing engines, ensures optimal fluidodynamic behavior due to even firing orders in comparison to the cross-plane crankshaft, and a unique engaging sound. Titanium conrods reduce the rotating masses and offer excellent material properties in terms of strength and lightness, reducing weight. The engine casting material consists of A357+Cu, the same used in motorsport applications.
The particularly robust and reliable finger followers covered in DLC (Diamond Like Carbon) can withstand speeds of up to 11,000 revolutions per minute - a range previously reserved for racing engines in motorsport. This is also where the engineers drew their inspiration for the engine layout concept. As is usual in motorsport, most of the auxiliary units are located on one side, including the two water pumps for the intercooler and engine cooling, as well the electronically-controlled barrel valve for fine temperature control.
The oil and water pumps, which are arranged in series on the right-hand side of the engine, are driven up to a specific ratio pump speed of 7,800 rpm. The engineers integrated the oil tank in one side of the engine that works according to the dry sump principle with five-stage gear scavenge pumps. As a result, the drive unit is flat and sits low in the Temerario lowering the center of gravity of the vehicle, while improving its handling characteristics. A newly designed water-cooling system ensures a balanced temperature regime. The internal cooling of the cylinder heads has been extremely refined using 3D printing technology for the casting core, allowing a uniform cooling of the combustion chamber and high knock resistance. The direct petrol injection atomizes the fuel extremely finely into the eight combustion chambers at up to 350 bar, thus ensuring fast and clean combustion.
The characteristics of a smoothly revving, naturally aspirated engine, with the power delivery of a turbo engine in combination with electric drives, is unique in the way it works and sounds. Lamborghini has thus succeeded in developing a new V8 biturbo that combines the pronounced linearity of the rev development in the previous Lamborghini naturally aspirated V10, with enormous power and torque of a modern turbo engine. In conjunction with the three electric motors, the system output is an outstanding 920 CV / 676 kW.
Engine Sound
Lamborghini has invested significant technical effort in the development of a unique and unmistakable audio experience from the Temerarioâs completely new drive system. Ensuring a highly emotive and unmistakably Lamborghini sound and sensation feedback.
"With the V8 biturbo, the amplitude and frequency of the sound increase as the engine speed rises, and thanks to the flat-plane crankshaft, subtle vibrations underline the power of the drive depending on the engine speed. For the occupants, the ride in the Temerario is an incredible experience for all the senses. Drivers will be roused by the powerful Lamborghini sound and will feel its unmistakable character with all senses," says Mohr.
The technical complexity of this special soundscape is immense. To ensure that the crescendo up to 10,000 rpm provides an emotional, sporty sound, Lamborghini integrates various technical measures and enriches them with high-frequency modulation effects.
A special connection between the engine banks enhances the sound effect of the power unit subject to the engine speed. Depending on the driving mode, the silencer box and exhaust valve of the V8 biturbo work in the low rev range to improve acoustic comfort. At the same time, the different driving modes are clearly differentiated through acoustic tuning.
An exhaust system routed from the manifold to the tailpipes also acoustically emphasizes the combustion processes of the engine. Lamborghini guarantees a clear and clean sound thanks to the smoothed pipe routing. The height and position along the transverse axis of the exhaust tailpipes further focuses the sharpness of the engine with a high frequency component, thus emphasizing its power.
In addition, Lamborghini has designed the engine mounts and body in such a way that the drive has a flat crankshaft character that can be felt by the driver at high engine speeds and under full load. Thanks to the flat-plane crankshaft, in which the crank pins are at an angle of 180 degrees, the V8 biturbo produces subtle vibrations.
Lamborghini makes the amplitude of these vibrations more pronounced at high engine speeds, which enhances the overall impression of speed and power at high revs. The sound engineers also manage to transport the pleasantly sporty acoustics into the interior and at the same time emphasize the desired frequencies by means of lightweight body parts and panels. The light vibrations transmitted to the frame provide a comprehensive sensory experience, in addition to the thrilling soundtrack. As the engine speed increases, the seat vibrations intensify, especially at higher engine speeds of up to 10,000 rpm: a speed range previously only known from motorsport.
Furthermore, an additional sound symposer emits acoustic waves into the interior, creating an immersive auditory experience in every driving mode.
Lamborghini has also designed a completely different soundscape for the different driving modes CittĂ , Strada, Sport and Corsa. In CittĂ mode, Lamborghini offers a high level of comfort with a special sound from the electric drive unit. The composition achieves a smooth and pleasant listening experience in urban environments. In CittĂ mode, the Temerario is emission-free and quiet.
In Strada mode, for country roads and fast autoroutes, occupants enjoy a comfortable and homogeneous V8 biturbo sound experience with evenly distributed frequencies, without any barking or sharp peaks for sporty yet discreet driving pleasure. In Sport and Corsa modes, Lamborghini amplifies the second- and fourth-order overtones of a V8 four-stroke engine and air-intake harmonics, creating an exhilarating and powerful listening experience. At speeds of up to 10,000 rpm, the engine not only delivers incredible power of up to 920 CV, but also an inimitable sound - a new Lamborghini sound of a new generation.
Three electric motors for support
The new drivetrain incorporates three electric motors. With 110 kW of power each, the electric motors are an integral part of the powertrain strategy. Two oil-cooled axial flow electric motors with a total peak output of 220 kW and up to 2,150 Nm of torque (the continuous output is 60 kW) drive the front axle when required to achieve all-wheel drive. The electric front axle weighs just 73 kilograms, and each electric motor only 15.5 kilograms.
A major challenge was the design of the powertrain to be as compact as possible. To achieve this, the engineers integrated the electric motor into the housing of the V8 biturbo, directly, without an intermediate clutch. This fills any turbo lag, no matter how small, at any speed delivering 300 Nm of torque. The entire electric drive unit is located compactly between the combustion engine and the dual clutch transmission. This electric motor also works as a starter motor and three-phase generator.
Furthermore, the two electric motors on the front axle also improve the power output and can transform the new Temerario into a fully electric super sports car. In this way, Lamborghini reduces CO2 emissions by up to 50 percent compared to the HuracĂĄn.
Battery
The Lamborghini Temerario is equipped with a lithium-ion high specific power (4500 W/kg) battery pack situated within the central tunnel, keeping the carâs 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 pack is 1550 mm long, 301 mm high, and 240 mm 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 V8 engine.
Thanks to the e-axle, the Temerario incorporates Lamborghini Dinamica Veicolo (LDV) 2.0 system. Electric torque vectoring increases the carâs agility in narrow cornering as well as its stability in high-speed cornering, distributing torque optimally to each wheel. Unlike conventional systems, the new torque vectoring intervenes on the brakes only when strictly necessary, to maximize efficiency and ensure a more natural driving style as well as an even higher level of performance. When braking, the e-axle and rear electric motor contribute to deceleration, reducing stress on the brakes while recharging the battery.
Dual-clutch transmission
The gears of the second Lamborghini super sports car in the High-Performance Electrified Vehicle (HPEV) category are shifted by an eight-speed dual-clutch transmission (DCT) installed transversally behind the V8. The newly-designed compact transmission meets all the requirements of such a powerful drive unit.
To save installation space and weight, the layout is not a standard DTC. An additional hollow shaft is used to share the same synchronizers for different gear torque paths. Without electrical components, the new DCT weighs less than the HuracĂĄn's seven-speed dual-clutch transmission and achieves faster shift times. At 560 millimeters long, 750 millimeters wide and just 580 millimeters high, the new DCT also remains extremely compact.
Lamborghini has installed the new eight-speed dual-clutch transmission behind the V8 biturbo. This creates sufficient space in the center tunnel for the lithium-ion battery that powers the electric motors. Another advantage is that this technical layout optimizes the weight distribution of the Temerario and ensures a compact wheelbase for ideal driving dynamics and balanced handling.
With the new eight-speed dual-clutch transmission, drivers experience extremely fast shift times even with a very sporty driving style and daily driving. Continuous downshifts in particular are easy: when braking and simultaneously pressing and holding the left shift paddle the transmission shifts down gears sequentially, allowing the driver to feel and hear the gear change. The long ratio eighth gear reduces the engine speed, which helps to optimize fuel consumption and improves drivability at cruising speed. The Temerario gearbox has been equipped with a mechanical reverse gear system.
DESIGN
Brave, unexpected and authentically a Lamborghini: with the Temerario Lamborghini Centro Stile has created a new and inimitable super sports car that opens a fresh chapter in Lamborghini design DNA. following a new styling with its own essential and iconic identity. The new design creates its own essential and iconic identity.
âThe Lamborghini Temerario marksdefinitivelya new milestone in our design language.We call it âessential and iconicâ with enhanced athleticism from its surfaces. Fromthe first glance, this is a puristic, futuristic and yet fascinating super sports car, with its compact and agile proportions, the new hexagonal light signature, the âFeel like a pilotâ interior design and its sharp lines emphasizing the new hybrid powertrain and itsfun-to-drive dynamics. We provide a clear view of the new V8 biturboengine:theemotionalheart of the carand an innovativesource of power,â says Mitja Borkert, Director of Design at Automobili Lamborghini.
The new carâs design points towards the future of Lamborghini's legendary mid-engine sports cars, while the shapes of the car stay pure, athletic and well-defined. With a clean-sheet design and new drive concept, the Temerario carries a connection to its legendary predecessors while its all-new persona is characterized by reduction, clarity, sharpness and recognizability. âWe have created an elevated stylistic experience with the Temerario: we started from scratch to combine design and dynamism into compact proportions, testifying that this is a true Lamborghini super sports car designed for everyday driving pleasure and track-driving fun,â explains Borkert.
Exteriors
From first glance, the Temerario reveals Lamborghini DNA in its typical Lamborghini silhouette: clear and puristic lines, short and compact overhangs, integrated aerodynamics and a bold shark nose.
The Lamborghini design language has evolved to create a new hexagonal Daytime Running Light (DRL) signature, rendering it strongly recognizable and identifiable from far away. The hexagon concept can be found as the main design theme throughout the car: on the main bodywork, the side air intakes, the taillights and in the remarkable hexagonal exhaust pipe. âThis unique hexagonal light signature ensures a high recognition value within the Lamborghini range, and is also a clearly identifiable in the distance,â emphasizes Borkert. The geometric hexagon paradigm has been one of Lamborghini's most recognizable symbols since the 1960s.
The hexagonal daytime running lights, which incorporate an air tunnel, are part of the design philosophy of incorporating lights within the aerodynamic concept. Furthermore, air channels positioned below the headlights improve the aero performance and cooling of the front high-performance braking system for better efficiency.
The Temerarioâs designers combine elements from aviation with a visceral muscularity that starts at the front. The design is characterized by well-formed athletic surfaces and a cabin that tapers towards the hexagonal tailpipes. The tip of the hood dominates the entire front end in a strong and striking shark's nose design: a symbol of bravery and speed. The sharp, elegant headlights are slightly overlapped by the hood, drawing inspiration from the sports motorcycle world. Air-guiding slats connect the low front spoiler with the hood, while fins on the sides direct the airflow along the flanks. Sharply shaped side skirts support the aerodynamics and increase downforce at the same time.
With a broad shoulder and long, powerful muscularity, the side stretches from the front over the door, emphasizing the extreme sportiness of the Temerario. The powerful and efficient air intakes behind the side doors ensure the necessary airflow for the V8 biturboâs performance and at the same time, visually enhance the chassisâ downforce. A fixed rear spoiler emphasizes the carâs rear width. The compact yet technical rear end incorporates details from motorsport, such as the wide diffuser that extends under the vehicle and the integrated exhaust tailpipes. The rear lights feature the new hexagonal design, also allowing air to pass through for engine cooling.
The roof is also functional in terms of aerodynamics. A slightly rearward offset profile directs the air directly onto the integrated rear wing. The designers almost invisibly integrated air inlets behind the passenger compartment above the sculpted shoulder: a highly functional component that helps supply the engine, radiator and turbocharger with sufficient air.
The heart of the Temerario is the new 4.0-liter V8 biturbo engine with an integrated axial flux electric motor. In realizing the new powertrain concept, designers and engineers developed a new chassis and body: the Centro Stile Lamborghini had the greatest possible freedom to present the drive system in a visually appropriate way to emphasize a true mid-engine feeling. Lamborghini presents the V8 biturbo openly, like a motorcycleâs engine under a transparent hood.
âWith the clean yet exciting styling of the Temerario, we give a new shape to the essential and iconic Lamborghini design language, and take a huge step towards the future,â says Borkert. âThe Temerario combines style and performance to perfection, presenting an unprecedented convergence of design, engineering and driver experience in a new model.â
