Lamborghini’s legacy gas-finest machines have been unapologetically loud, brash, and in your face with sonorous symphonies performed by gasoline-guzzling V12 and V10 engines. Today, the brand is in its electrification age, with three roam-in hybrids: the Urus SE SUV, the pinnacle-tier Revuelto, and the newest Raging Bull, the Temerario. Don’t call them PHEVs, although. Lamborghini calls them HPEVs, or high-performance electric automobiles. Emphasis is on the performance, no longer the efficiency, although the hybrid lineup benefits from each.
Whereas skeptics may have no longer believed a Lamborghini hybrid may match the pleasure of its predecessors, the statistics reveal them injurious. Lawful compare the Temerario to the car it’s replacing, the iconic Huracán. The vitality delta alone is spectacular; the Temerario boasts a total of 907 horsepower generated by a brand-new twin-turbo 4.0-liter V8 that’s boosted by three electric motors, whereas essentially the most highly efficient versions of the V10-toting Huracán tapped out at 631 hp.
Can the Temerario match the popularity of the Huracán, Lamborghini’s handiest-promoting supercar ever? Automobili Lamborghini Chief Technical Officer Rouven Mohr says yes.
“To be factual, the Temerario is a powerful extra mature car,” he says. “It has a performance stage that was never that you can tell about ahead of. It’s in a assorted league and it’s even extra enjoyable.”
As a cherry on the proverbial sundae, the Temerario is the first Lamborghini supercar geared up with Drift Mode. Push a button on the steering wheel to activate its tail-wagging prowess, and you’re ready to transfer. Utilizing on grippy Potenza Sport tires co-developed with Bridgestone, the Temerario is eager to slump sideways on the track as although it’s on ice.

Revving it as a lot as 10… thousand
The Temerario’s hybrid setup is all new, carrying over nothing from the Huracán’s fierce powertrain, Mohr says. The usage of a “hot V” setup, which places the turbochargers for the duration of the V-shape of the piston configuration, the turbos spool up faster than they achieve in a “chilly V,” in which the turbos are additional from the heat.
A chilly V can finest rev as a lot as 7,500 rpm, Mohr says, and Lamborghini was targeting a increased number. With a “hot V,” the turbochargers are nestled nearer to the exhaust manifolds, so the gases have a shorter path to the turbine. As a result, there may be better stress consistency, temperature and pace, enhancing efficiency. And better efficiency means much less turbo lag—in reality, nobody wants a supercar with turbo lag.
Lamborghini says the Temerario is the first and finest manufacturing great sports car engine able to reach 10,000 rpm, a feat typically finest achieved in motorsports. That’s no lie; even the newest Ferrari in the stable, the non-hybrid 6.5-liter V12 powered 12Cilindri supercar, falls unbiased a limited in the back of the Temerario at a rate of as a lot as 9,500 revolutions per minute.
In narrate to achieve the Lamborghini model’s performance curve with a turbocharged engine, Mohr and team started from zero. They decided to transfer with large turbochargers to enable a vitality explosion at high revs, but they also wanted to balance that with excellent drivability without turbo lag, Mohr explains.
The magic in the back of this supercar is a triple electric motor infusion, one at each entrance wheel and one between the engine and the eight-pace dual-grab transmission. All three are axial flux motors built by YASA, a subsidiary of Mercedes-Benz. Axial flux electric motors are 50 p.c lighter and 20 p.c of the depth of a typical radial machine frail in many EVs, YASA states. The variation visually inspires the variation in width between vintage tv or computer and today’s flat display shroud TVs, and the performance is even extra important than the looks. The usage of stacked constructing, an axial flux motor packs a dense amount of vitality into a compact machine.

Training the body for a new engine skills
The primary time he drove the Temerario, Mohr says, he had to train himself for the new using character. That required him to change the way he shifted gears.
“You have in your brain two categories: the naturally aspirated [engine], which has no low torque at all, so that you have to rev it up because in any other case you really feel bored and unhurried,” Mohr says. “And you have the turbo category, which gives you high torque at low revs, but then nothing is really happening. Once you rev it up it gets a bit louder but it’s missing this extra punch.”
The Temerario, he explains, combines each. There’s the linearity, the enhance, the torque stage and a apparently unending vitality curve. At first Mohr automatically started transferring at about 6,000 rpm and he says he compelled himself to learn to stay on the throttle. What he chanced on was that what happens between 6,000 rpm and 10,000 is breathtaking.
“There are no longer even many naturally aspirated engines on the earth that rev as a lot as 10,000,” he says. “For a turbo engine there may be finest one other in my mind: the Formula 1 base engine.”
The Temerario has a totally assorted character than the Revuelto, Mohr says. In contrast, the pricier Revuelto is powered by a naturally aspirated 6.5-liter V12 engine plus three electric motors. Starting at $600,000-plus, here’s the flagship car of the Lamborghini brand, representing what Mohr calls the “pinnacle” of the product range.
On the opposite hand, the Temerario was designed extra as a daily driver. Every part from the body kind to the aerodynamics to the engine had been calibrated for a enjoyable, extra casual skills than the elegantly engineered Revuelto.
