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.
“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 optimise 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.
