Sant’Agata Bolognese/Carmel-By-The-Sea, August 2024
Automobili Lamborghini unveiled the Temerario, the legendary Italian marque’s new twin-turbo V8 hybrid super sports car, at The Quail, A Motorsports Gathering, the highlight of the annual Monterey Car Week in California.
Succeeding the Huracán, the Temerario sets a new benchmark for the super sports car segment with a total power output of 920 CV, reaching a top speed of more than 210 mph (over 340 km/h) and accelerating from 0-62 mph (0-100 km/h) in 2.7 seconds. The Temerario is the second Lamborghini HPEV (High Performance Electrified Vehicle) and third step in the electrification strategy for the company, completing the hybridization of the entire Lamborghini lineup following the Revuelto and the Urus SE.
The Temerario replaces the Lamborghini Huracán, which debuted in 2014 and has been the greatest-selling super sports car in the history of the Sant’Agata Bolognese-based carmaker. As stated by Stephan Winkelmann, Chairman and Chief Executive Officer of Automobili Lamborghini, “Every new Lamborghini must surpass its forerunners in performance terms.” With the Temerario, the new hybrid plug-in reaches a new paradigm in terms of performance, sportiness and driving pleasure. The Temerario is the first and only production super sports car engine able to reach 10,000 rpm: a feat typically only achieved in motorsports.
“With the Temerario, we’ve exceeded our expectations with what the mid-engine sports car can be in terms of performance and design,” said Winkelmann. “The Temerario completes the next chapter in our Direzione Cor Tauri plan by hybridizing the full product line, while we continue the development of our full electric model debuting at the end of the decade.”
Alongside its global unveiling, the Temerario made its virtual debut in the Lamborghini Lab, the official design and driving experience on Roblox, created by Automobili Lamborghini to inspire new generations. In the virtual realm, you can customize your own Temerario by using colors and options from Lamborghini’s Ad Personam studio. Experience unparalleled performance as you take your customized supercar on the track, competing with friends and challengers worldwide.
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. “We 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,” says Rouven Mohr, Chief Technical Officer at Lamborghini.
“Temerario is in a league of its own, in terms of engineering solutions and performance.”
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.
By 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,” 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 “torque gap filler” 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 “hot V8” 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.
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 Huracán.
