Mercedes-AMG One smashes manufacturing automotive Nürburgring lap file
Mercedes-AMG has damaged the manufacturing automotive lap file with its AMG One hypercar, posting a 6:35.183 time that smashed the earlier file set in a Manthey-tuned Porsche 911 GT2 RS by over eight seconds. The lap file was damaged with solely minutes to spare within the day’s session, with skilled racing driver and AMG ambassador Maro Engel on the wheel.
The lap was accomplished with an AMG One in road-going specification, working a set of Michelin Pilot Sport Cup 2 R MO tyres that have been developed for the Mercedes-AMG One undertaking. As has already been nicely documented, the AMG One’s hybrid powertrain combines a 1.6-litre V6 engine derived instantly from the Formulation 1 program with three electrical motors that collectively produce a peak energy determine of 1048bhp, making it considerably extra highly effective than the earlier GT2 RS file holder.
This big energy determine is mixed with a cutting-edge aero package deal that features lively aero parts across the nostril, entrance wheel arches, rear diffuser and rear wing. It’s this mixture that helped the One produce this distinctive time, one which sits head and shoulders above the opposite street automotive lap instances on the well-known circuit.
Because of the means the hybrid powertrain delivers its efficiency, Maro Engel didn’t simply have the duty driving the One across the fearsome Nordschleife, but in addition needed to handle the powertrain’s battery consumption to make sure most efficiency on the lap’s higher-speed sections. By means of cautious administration, the AMG One nonetheless achieved a 209mph high pace on the Döttinger Höhe, additional aided by the inbuilt DRS system.
Commenting on Mercedes-AMG’s triumph, Maro Engel commented ‘that was actually an unforgettable expertise. I didn’t anticipate that we’d be capable of set such a lap time with these monitor situations. In some essential areas of the monitor, it hadn’t dried fully but and was due to this fact difficult. That was a particular problem.’
This astonishing time is a testomony to the AMG One’s lengthy growth, having now lastly accomplished its sturdiness testing to be one of the vital excessive road-going automobiles to ever be placed on sale.
In fact the AMG One’s hypercar rivals, such because the Aston Martin Valkyrie, are but to aim their very own lap instances, however with a brand new 6:36.183 time, we are able to take into account the gauntlet thrown down for a brand new period of Nürburgring lap file makes an attempt.

Mercedes-AMG One – manufacturing
After over half a decade of intensive growth, the Mercedes-AMG One is now formally in manufacturing. AMG has partnered with Canadian outfit Multimatic within the setup of a small manufacturing facility in Coventry, the place all 275 items shall be assembled. The One’s F1-derived powertrains will come from down the street at Mercedes F1’s Brixworth-based engine works, creating what is going to grow to be Mercedes-AMG’s most excessive street automotive ever.
First clients are attributable to obtain their £2.5m hypercars from later this yr, every not simply using F1-inspired engineering, however a literal sister unit to the engine that is helped Mercedes-AMG Petronas win eight constructors championships. There’s been loads of controversy round its growth, and its Aston Martin Valkyrie rival, however now we are able to reveal the technical particulars and numbers for the automobiles we’ll see on street.

What marks out the One from the hypercars earlier than it’s the drivetrain. Be in little doubt that the ‘Formulation 1 automotive for the street’ tag line isn’t simply advertising and marketing guff. It’s a truth. Aft of the passenger cell you’ll discover a model of the F1 automotive’s EQ POWER+ powertrain that has propelled Mercedes to eight consecutive F1 constructors titles, 5 greater than when the Mission One was initially introduced.
The 1599cc V6 petrol combustion engine is inbuilt the identical AMG Engine Works facility in Brixworth that builds the Mercedes F1 engines, and is supplemented within the One by 4 electrical motors that each one mix to ship a 1048bhp most energy determine. As with all hybrids, the height energy just isn’t a easy sum of all of the contributing parts, however the peak determine out there from all the weather at anybody time.
The V6 itself is rated at 565bhp generated at 9000rpm, with a peak rev limiter of 11,000, or 2500rpm lower than Hamilton’s Sunday driver. This equates to a selected output per litre of 359bhp – a Mercedes-AMG A45 S is 208bhp/litre for distinction, and even one thing as extremely strung because the Koenigsegg Jesko (which has but to show dependable) doesn’t fairly match the AMG with 313bhp/litre.
So it’s a pure F1 engine, then? Not precisely. AMG calls it a ‘bespoke unit’ that marries parts from a number of generations of its F1 engine. The engineering is precisely the identical, although. Air is fed into the engine by a mixed mechanical and electrically-driven turbocharger with the exhaust turbine situated close to the exhaust and the compressor close to the roof-mounted air consumption. They’re joined by a protracted shaft to which is linked an 80kW (121bhp) MGU-H electrical motor. This primes the turbocharger to get rid of lag and, in response to AMG, provides the V6 sooner responses than a naturally-aspirated V8. The electrical motor additionally recovers waste exhaust vitality which may then be used to replenish the hybrid battery or instantly drive the MGU-Ok.
MGU-Ok? It stands for Motor Generator Unit Kinetic, one other electrical motor positioned on the facet of the crankcase and instantly linked to the crankshaft. It may possibly both drive the crankshaft, including 120kW (160bhp) to the facility tally, or be pushed by it. AMG claims that the mixed petrol-electric parts working as an entire unit obtain an unprecedented thermal effectivity of round 40 per cent in opposition to a norm of 30-32 per cent. It’s as shut as you’ll get to guilt-free 1000hp+ motoring.
Sitting behind the engine is a bespoke seven-speed, single clutch transmission and a limited-slip differential. Above that’s the exhaust system which, not like the F1 automotive’s model, has a silencer, catalytic converter and two petrol particulate filters which make the One Euro6 emissions compliant – a consideration AMG may not have made when the undertaking was initiated all these years in the past.
From right here, there are then two extra electrical motors that energy the entrance axle, which collectively produce 240kW (321bhp). These energy every entrance wheel independently, and permit full torque vectoring. The lithium ion battery cells – their configuration, connectors and direct cell liquid cooling – are a direct carry from F1. Nevertheless, the 800-volt excessive voltage system (contained in two battery housings on both sides of the automotive) has round 4 instances the capability utilized in F1 at 8.4kWh.
The upper voltage degree reduces voltage losses, not least within the cables. It additionally permits considerably shorter charging instances with a continuing present degree. The One’s driving applications will even have an all-electric mode with simply the entrance axle pushed, giving a variety of as much as 11 miles. Essentially the most excessive ‘dynamic’ mode, alternatively, will undertake settings utilized in F1 to realize the absolute best lap instances in qualifying.
Although a formidable feat, its complexity actually hasn’t helped its weight determine. The Mercedes-AMG One suggestions the scales at 1695kg (DIN), a number of hundred greater than even previous-generation hybrid hypercars such because the McLaren P1. For context, that provides it a 618bhp per tonne power-to-weight ratio, simply 55bhp per tonne greater than the £280,000 McLaren 765LT.
In consequence, efficiency figures aren’t as mind-boggling as you may anticipate for a £2.5million machine. 0-62mph is available in 2.9sec to match the Ferrari F8 Tributo, with the 7sec 0-124mph time solely sufficient to degree with the McLaren 765LT – high pace comes at 219mph.
Chassis, brakes and wheels
The five-link suspension system is a horizontally-packaged, pushrod damper setup with coilovers and three-way adjustable dampers. The setup negates the necessity for a conventional anti-roll bar up entrance, stopping lateral roll and disassociating lateral actions from vertical actions. The suspension can be in a position to be hydraulically lowered by 37mm in its most aggressive monitor mode.
The chassis itself is derived from a carbon monocoque with an aluminium entrance subframe. Like F1 automobiles, and a number of the actually critical supercars, the rear-mounted gearbox and limited-slip differential act as careworn members of the chassis, to which the rear suspension is instantly mounted.
The brakes are carbon-ceramic and, due to the relative lack of mass, are a surprisingly restrained six-piston setup up on the entrance with 398mm discs, and four-piston calipers on 380mm discs in use out again. There are two wheel designs out there, each coming with their very own intelligent carbonfibre aero gadgets. The usual set is a 10-spoke design made out of solid aluminium, the optionals being a 9-spoke Magnesium design. The wheels are staggered in diameter and width – the fronts are 10×19-inch on 285/35 ZR19 rubber, with 12×20-inch items on 335/30 ZR20s on the rear. The tyre of selection is a Michelin Cup 2R.
Lively aerodynamics and design
Whereas the powertrain is a homage to Formulation One and the chassis an train in up to date hypercar engineering, the lively aero is a imaginative and prescient of the long run, with moveable parts everywhere in the AMG One’s floor. There are three principal lively aero parts on present – moveable flaps constructed into the entrance diffuser, entrance wheel arch vents and the moveable rear wing. The splitter and rear wing are parts we’ve seen earlier than, each working in tandem to both enhance downforce or cut back drag.
The mechanical flaps on the entrance wheel arches are completely different, although, opening to scale back inner strain throughout the wheel wells by extracting air via them. In contrast to the opposite lively aero elements, although, there’s no actual benefit to these parts being closed as they provide no advantages apart from maybe holding grime and dirt throughout the arches, making them extra of a visible assertion than an enormous leap in aerodynamic effectivity.
The engine cowl is a two-piece unit that flanks the central fin which is fashioned from the tail-edge of the roof-mounted consumption. Each elements are stable carbonfibre, however have vanes for warmth extraction and two huge NACA ducts that ought to assist hold the engine bay cool. With such a highly-strung nature to its F1-derived engine, the AMG One’s cooling necessities are excessive, explaining the intensive focus of cooling and aero administration.
The design is in any other case largely unchanged from that preliminary idea automotive we noticed in 2017, together with the pared-back inside and F1-inspired steering wheel. Whereas it’s not the prettiest supercar on the earth, it does look extraordinarily centered, whereas nonetheless incorporating a variety of AMG design parts that even now are nonetheless related to the present AMG vary. Nevertheless, the automotive’s journey from 2017 to now hasn’t at all times been easy crusing, making the AMG One’s backstory one which’s simply as fascinating because the automotive itself.
The advanced and controversial backstory
In 2017, Tobias Moers was head of AMG and the F1 group was on the peak of its dominance. Electrification was within the distant future, and the premium section produced big gross sales volumes, giving Mercedes-Benz and lots of of its rivals an especially wholesome outlook into the close to future.
Within the hypercar house, McLaren, Porsche and Ferrari had hogged the limelight with the P1, 918 Spyder and LaFerrari, and AMG needed in, so got here up with the concept of the Mission One, a design that utilised its championship successful engine in a manufacturing automotive. This was an enthusiasm shared by Aston Martin, then led by Andy Palmer. Aston’s partnership with the Crimson Bull F1 group spawned its personal F1-inspired hypercar that, just like the AMG, would additionally go a lot additional than the earlier hypercar era. The 2 tasks would create the AMG Mission One and Aston Martin Valkyrie rivalry that’s nonetheless at play at this time.
Sadly, the nice instances have been to not final, as growth on each tasks hit a number of snags, for fairly completely different causes. AMG’s points have been surrounding the powertrain, which was proving particularly tough to transform to street automotive use on account of its inherently extremely strung nature. F1 engines, whereas extra resilient than beforehand, are nonetheless designed for a life-span of some thousand miles, not the tens of 1000’s anticipated from a street automotive – even one as specialised as this. To make issues extra difficult, Mercedes and Aston Martin had been tightening their relationship, collaborating each on and off the race monitor, making the self-importance undertaking in opposition to Aston Martin now an virtually internalised battle, one with no winners.
Quick ahead previous Aston Martin’s disastrous IPO, Mercedes-Benz purchases a fair greater 20 % stake within the British model, finally resulting in the appointment of ex-AMG boss Tobias Moers as Aston Martin CEO, taking on the function from Andy Palmer.
This left the brand new boss of Aston Martin to forge forward with the Valkyrie that might go head-to-head along with his personal ardour undertaking, the AMG One. To make issues extra difficult for Moers, Aston Martin would then dissolve its partnership with Crimson Bull in F1, creating as an alternative its personal group from Racing Level, which itself was constructed up by new Aston Martin Chairman Lawrence Stroll.
But each tasks have continued on, albeit with substantial delays, and are attributable to be delivered when neither Aston Martin or Mercedes-AMG maintain any benefit in F1. To high all of it off, neither of the visionaries behind the tasks from the beginning are instantly concerned with both model, with Tobias Moers quickly to make his exit from Aston Martin and Andy Palmer now pursuing different avenues. Regardless of the narratives of each these hypercars changing into muddled up by firm politics, the saga has left us with two of probably the most fascinating street automotive tasks the automotive trade has ever seen. All that’s left to do is drive them.
