Nowadays, big energy does not essentially have to come back from an engine boasting big displacement. Compelled induction means you possibly can have a a lot smaller engine producing the identical, if no more energy, than an 8.0-liter naturally aspirated V10. In truth, essentially the most power-dense engine presently on sale is made in America, and it is smaller than the three.4-liter twin-turbocharged V6 used within the Toyota Tundra.

In terms of manufacturing engines with essentially the most horsepower per liter, it is not Koenigsegg, Hennessey, and even Bugatti that takes high honors.
However what in case you take away the constraints of the engine presently being in manufacturing? Technically, the AMG One remains to be in manufacturing. It takes some time to construct 275 models and all of them are bought out. The Czinger 21C solely just lately went into manufacturing and you may nonetheless order one. However that is sufficient administrative speak for now.
If we glance again to 2022, there’s one little motor that takes the cake on the subject of large energy in a small package deal; the Mercedes-Benz PU106B. We’re speaking in regards to the turbocharged 1.6-liter V6 within the Mercedes-Benz AMG ONE hypercar. It is a formidable feat of engineering, if solely as a result of it is the primary time a manufacturing automotive was fitted with a Formulation 1 engine. To shed some mild on this marvel of a motor, CarBuzz invitations you to learn on and be taught simply what precisely went into making the power-packed Mercedes-Benz PU106B.
The next info pertaining to the PU106B motor was sourced immediately from websites akin to Mercedes-Benz.com.
The Mercedes-Benz PU106B Is A Small Bomb
Earlier than we dive too deep into the One, we first want to clarify particular energy output. It is how a lot energy an engine produces per liter. The present manufacturing automotive chief produces 328.86 hp/l, whereas the One hits 353.75 hp/l.
The Mercedes-Benz PU106B’s story begins again in 2014, when Formulation 1 launched new engine rules. The game dropped from the well-known 2.4-liter V8s to an all-new 1.6-liter V6 hybrid powertrain. The PU106 is understood at present as probably the most profitable F1 engines ever created. It has seen use by a number of racing groups, akin to Williams, McLaren, Lotus, Drive India, and Aston Martin. It was so profitable that Mercedes-AMG determined to place it in a street automotive, which turned out to be a lot trickier than anticipated.

The documentary will cowl all the things from technical challenges to retaining clients completely happy, with greater than three years of unique information and archive entry.
The powertrain AMG selected was the PU106B, which powered Lewis Hamilton to an F1 championship in 2015. The PU106B needed to be tailored to work in a street automotive, however it’s nonetheless very a lot an F1 engine, utilizing a number of elements carried over from the racing automotive. And we’re not simply speaking about an electrical turbocharger such as you get on most trendy Mercs. The One has lively aerodynamics, and even a system that turns warmth into vitality to assist the regenerative braking feed the battery.
Many of the work went into making the One socially acceptable. An F1 automotive idles at 5,000 rpm, which isn’t ideally suited in a road-legal automotive. This automotive is so advanced that an onboard system has to warmth the catalytic converters earlier than you possibly can interact the engine.

The PU106B’s specs are nothing if not spectacular. The engine itself is able to big horsepower with none assist from its hybrid powertrain or electrical turbocharger, and boasts a formidable quantity already. When you add in its electrical helpers, issues flip from fairly spectacular to downright mind-blowing.
Because the desk above states, the PU106B is able to producing 566 horses earlier than the rest is bolted. The remainder of its powertrain is made up of 4 electrical motors, two of which reside on the AMG ONE’s entrance axle, and make 161 horsepower every. This pair of motors additionally provides the automotive all-wheel drive grip. A 3rd motor is nestled inside the PU106B’s block, affixed to the crankshaft. It makes 161 horsepower and an undetermined quantity of torque. The distinctive E-turbo electrical motor is bolted on to the turbocharger, and is supposed to cut back turbo lag because it does not depend on exhaust gasses to spin. All 4 electrical motors comprise energy-recovering capabilities.

These engines squeeze essentially the most energy out of the smallest displacement.
The sum of the AMG ONE’s energy is 1,049 horsepower and an unspecified quantity of torque, as Mercedes-Benz claims torque measurement is unimaginable because of the complexity of its powertrain. Dealing with all of this energy is a seven-speed automated guide transmission sporting a single-disc clutch.
There’s fairly an enormous catch with the PU106B, nonetheless. On account of its F1 heritage, it is not meant to be notably long-lasting. Based on Mercedes-AMG, the engine will solely final about 31,000 miles, after which it’s going to have to be utterly overhauled and/or changed as a consequence of put on. This course of prices 850,000 Euros or simply over $920,000. That is a big worth to pay for a brand new motor. However, in case you’ve bought the scratch to cowl the preliminary price of a complete AMG ONE, you are greater than doubtless able to paying for its pricey engine overhaul.

The PU106B’s F1 Roots
As was talked about beforehand, the PU106 engine household’s story started in 2014. In complete, the PU106 engine has seen a complete of 11 totally different iterations, every extra highly effective than the final. The primary model, the PU106A, noticed motion in 2014 and threw out 870 horsepower courtesy of the same hybrid powertrain as mentioned above. The PU106B got here a couple of yr later, and, after all, noticed use within the Mercedes-Benz AMG ONE. The engine’s most profitable season was 2016, the place it noticed 19 wins out of a complete of 21 races in its PU106C iteration.

At present, the PU106 household has seen intensive upgrades since its introduction. In complete, the motor has been answerable for propelling a number of Formulation One vehicles to a complete of 119 wins since 2014, a particularly spectacular quantity. In truth, one instance, the Mercedes-AMG M11 EQ Efficiency, has been heralded as probably the most profitable Formulation One vehicles of all time, primarily due to its PU106-family motor. Nowadays, the engine has seen a drastic discount in success on the skilled circuit. This has nothing to do with the powertrain, nonetheless.
The Mercedes-Benz AMG ONE Is Thoughts-Blowing On Monitor
A Few AMG ONE Lap Data
Nürburgring Nordschleife: 6:35.183 Hockenheimring: 1:38.563 Monza: 1:43.902
In brief, it is secure to say the AMG ONE is nothing lower than extraordinary, mainly due to its F1-bred powertrain. Nonetheless, there are a number of different facets of the supercar that make it such a track-munching monster.
For one, its total design is a no-holds-barred, precisely-shaped aerodynamic masterpiece. Its rear wing is a two-piece design that includes an F1-bred RS system, which permits for extra velocity to be gained on straightaways on the expense of downforce. It additionally boasts lively slats on its entrance splitter, which transfer about when uncovered to differing aerodynamic circumstances. They can even change form based mostly on the motive force’s selection of driving mode.

These road-legal machines are criminally fast.
The AMG ONE has a pair of gigantic air intakes on its entrance fascia, together with a roof-mounted unit to supply much more contemporary air to its 1.6-liter powerplant. Moreover, a centrally-mounted fin sits atop the mid-mounted engine and extends to the rea of the AMG ONE which helps preserve the automotive secure at excessive speeds, very like an empennage on an airplane. Even the AMG ONE’s rims have been designed with aerodynamics in thoughts, as they’re in a position to carry extra downforce via corners and assist preserve the automotive planted.
Utilizing all of those aerodynamic marvels, the AMG ONE has already set fairly a couple of lap data. Probably the most well-known of which is its six-minute, 30-second time across the Nürburgring by the hands of Maro Engel, an AMG manufacturing unit driver. It additionally set a lap report across the Monza Circuit, together with different circuits such because the Pink Bull Ring and Hockenheim.
