Mercedes-AMG Project ONE

 

World premiere at the IAA.

The Mercedes-AMG Project ONE will celebrate its world premiere at the International Motor Show (IAA) in Frankfurt/Main: for the first time, the two-seater supersports show car brings the very latest and efficient, fully-fledged Formula 1 hybrid technology from the race track to the road almost par for par to represent the highlight of AMG’s 50th anniversary. This high-performance hybrid is said to produce over 1,000 PS and reach top speeds beyond 350 km/h. The show car combines outstanding race track performance and day-to-day suitable Formula 1 hybrid technology with exemplary efficiency. This is a world first.

 

One turbo engine and four electric motors.

The high-performance plug-in hybrid drive system of the Mercedes-AMG Project ONE comes directly from Formula 1, and was realised in close cooperation with the motorsport experts of Mercedes-AMG High Performance Powertrains in Brixworth. It consists of a highly integrated and intelligently networked unit comprising one hybrid, turbocharged combustion engine with a total of four electric motors. One has been integrated into the turbocharger, another has been installed directly on the combustion engine with a link to the crankcase and the two remaining motors drive the front wheels.

 

Mid-engine with up to 11,000 rpm.

The 1.6-litre V6 hybrid petrol engine with direct injection and electrically assisted single turbocharging comes directly from the Mercedes-AMG Petronas Formula 1 racing car. To achieve high engine speeds, the mechanical valve springs have been replaced by pneumatic valve springs. The vehicle is mid-engined (ahead of the rear axle) and it can easily reach speeds of 11,000 rpm, which is currently unique for a roadgoing vehicle. However, for higher longevity and the use of commercially available Super Plus petrol instead of racing fuel, it remains significantly below the F1 engine speed limit.

 

Driving Performance of the future.

Ever since the early days of motorsport, engineers have dreamed of bringing motor racing technology to the road. Mercedes-AMG is now making this dream a reality at the very highest level. “Motorsport is not an end in itself for us. Faced with intense competition, we develop technologies from which our production vehicles also subsequently benefit. We are drawing on our experiences and successes from three constructors’ and drivers’ world championships to bring Formula 1 technology to the road for the first time: in Mercedes-AMG Project ONE”, says Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.

The concept car gives specific indications of what to expect from the upcoming production model. “The hypercar is the most ambitious project we have ever undertaken. It marks yet another pinnacle of the successful, strategic development of Mercedes-AMG towards a performance and sports car brand. Project ONE raises the bar in terms of what is currently technologically feasible and thanks to its combination of efficiency and performance it represents an absolute benchmark. At the same time, Project ONE provides an outlook on how AMG will define driving performance in the future”, Tobias Moers explains as the Head of Management at Mercedes-AMG GmbH.

Rev wonders on the front axle.

The electric motors on the front axle are also true rev wonders, with rotor revolutions up to 50,000 rpm – current state of the art is a speed of 20,000 rpm. The very high-revving engine is additionally boosted by a high-tech turbocharger. The exhaust gas and compressor turbines are separated from one another and located at an optimum position to the exhaust side and to the intake side of the V6 engine, and connected to one another by a shaft. This shaft features an electric motor with approximately 90 kW which, depending on the operating status, electrically drives the compressor turbine with up to 100,000 rpm – for instance when moving off or following load changes. The Formula 1 designation for this unit is MGU-H (Motor Generator Unit Heat).

Responds faster than a naturally aspirated V8 engine.

The major advantage: the dreaded turbo lag – the delayed response to accelerator pedal commands owing to the inertia of the large charger – is completely eliminated. The response time is greatly reduced, and is even shorter than that of a naturally aspirated V8 engine. The electric turbocharger brings about another advantage: it uses parts of the surplus energy from the exhaust system to generate electricity, and either stores it in the high-voltage lithium-ion battery as part of recuperation or provides additional drive power by feeding it to an additional electric motor. This motor produces 120 kW, has been installed directly on the engine and features a link to the crankshaft via a spur gear (MGU-K = Motor Generator Unit Kinetic) – another technology that ensures maximum efficiency and performance in Formula 1.

Fully electrically driven front axle.

The thermal efficiency of the combustion engine with electric turbocharger (MGU-H) in conjunction with the electric motor on the crankshaft (MGU-K) will be over 40 percent. This is a previously unattained peak value for series production vehicles. There will also be two further 120 kW electric motors at the front axle.

Each is connected to a front wheel via a reduction gear. The fully electrically driven front axle allows individual acceleration and braking of each front wheel, and therefore selective torque distribution for particularly high levels of vehicle dynamics.

Impressive acceleration figures.

The driver can move off purely electrically, initially with just the electric motors on the front axle driving the hypercar and the electric motor on the crankshaft supporting short-term acceleration wishes. If the driver presses the accelerator more firmly and demands more output, the V6 engine also switches on. The drive system unfolds its full power as the engine speed increases. Impressive acceleration figures are possible with the Race Start function: acceleration from zero to 200 km/h takes under six seconds. If the driver’s foot leaves the accelerator again to let the car coast, the system switches to electric drive at the front axle – whilst braking under normal driving conditions recuperates up to 80 percent of the energy, which is fed into the battery.

Automated 8-speed manual transmission.

Power is transferred to the rear wheels by an 8-speed manual transmission that has been entirely developed from scratch for the Mercedes-AMG Project ONE. It is activated hydraulically and can be operated in automated mode or manually using the shift paddles. The car is equipped with an advanced, weight-optimised ceramic high-performance compound braking system. Its low weight reduces the unsprung masses, thus improving driving dynamics and agility.

Innovative pushroad suspension.

Multi-link designs are used at the front and rear. The adjustable coil-over suspension has several special features: Both push-rod spring struts have been installed across the direction of travel. The innovative arrangement of the spring/damper unit replaces the function and application of conventional tubular cross members. The overall setup of the springs and dampers is configured for perfectly balanced, easily controlled and above all sporty handling characteristics. These are also assisted by all-wheel drive and torque vectoring.

Not only a street-legal racing machine.

The Mercedes-AMG Project ONE will not only be a street-legal racing machine that directly brings current Formula 1 hybrid technology onto the road and combines top-class race track performance with full day-to-day suitability. Its purpose is also to obtain extensive findings about performance-oriented plug-in hybrid drive technology, further developments of suspension layouts and extended onboard electronics that will later benefit series production AMG cars.

2018 Mercedes AMG GT R

New 2018 AMG GT R it's Radical

Once again, the skunkworks in Affalterbach has driven a new stake into the ground and set the new benchmark for racetrack-bred performance. Introducing the 2018 Mercedes-AMG GT R, the embodiment of all that is Mercedes-AMG: driving performance at its most passionate, pure and uncompromising.

 The Mercedes-AMG GT R is designed as a track car off the showroom floor, with sinister aesthetics and adrenaline-pumping performance dynamics to match.  Active rear-axle steering turns up to 1.5 degrees of toe angle for increased cornering response and high-speed stability. The light dual-mass flywheel is responsive and ready to handle rigorous torque spikes of transmission kickdowns on-track.

When it comes to styling, the purpose remains the same — extreme performance. Aggressive aerodynamics combine with an advanced cooling system to reduce drag and improve heat dissipation that comes with rigorous track use. And the wide track makes an audacious persona feel all the more visceral and real when you´re behind the wheel.

The heart of the "beast"

The heart of this new high-performance athlete, the AMG 4.0-litre twin-turbo engine, has an output of 577 hp, the peak torque of 516 lb-ft is available between 1,900 and 5,500 rpm. Its handcrafted V8 biturbo engine with "hot inside V" configuration grinds out 74 hp more than the previous top-of-the-range GT S engine, and the all-new AMG TRACTION CONTROL with 9 input levels is literally at your fingertips in the center console. The motorsports technology goes beyond just the engine. Forged cylinder heads are durable and more resistant to heat. And a sophisticated engine management system adapts based on your driving style, reading your throttle inputs, g-force indicators and more.

The seven-speed dual-clutch transmission configured in transaxle layout at the rear axle has likewise been extensively revised by the AMG developers. First gear in the AMG SPEEDSHIFT DCT 7-speed sports transmission has a longer ratio, while seventh gear and the final drive have shorter ratios to allow a more agile acceleration experience.

The suspension

 The suspension of the new AMG GT R is designed for racetrack use. Wishbones, steering knuckles and hub carriers on the front and rear axles are manufactured out of forged aluminium in order to reduce the unsprung masses.

Aerodynamics

 

Aerodynamics engineers and designers worked together intensively during development of the AMG GT R. The low-slung front section and the forwards-inclined radiator grille create a distinctive "shark nose" impression and make the car appear to sit lower on the road.

The specially developed exhaust system not only delivers genuine racing car sound, it also saves around six kilograms of weight compared with the AMG GT S thanks to the use of titanium for the rear silencer and thin-walled stainless steel for the front section of the exhaust system.

The all-new 2018 Mercedes-AMG GT R begins its reign in summer 2018.

Mercedes AMG F1 in the 3rd day of Barcelona pre-season tests

Mercedes AMG F1 2017 - The time is down ... a decade

 
 
Valteri Bottas smashed the time lap to 1:19.705, a mark that beats largely the last years records, in this 3rd day of tests preparing the 2017 F1 season in Barcelona, in Montmeló Circuit of Catalunya.

It seems the Champion squad are ready to deffend the title. Let's see how Ferrari responds considering the positive feedback that La Scuderia gave yesterday prompting great lap times too.

Mercedes-AMG F1 2017

Mercedes-AMG Petronas Motorsport today, 23rd February 2017, took the first step on the road to the 2017 Formula One season with the official presentation of the new F1 W08 EQ Power+.
The new car was launched to the team’s fans from the Silverstone garages via a live 360-degree broadcast on Facebook, YouTube and the Team’s official website – reinforcing the “fan first” approach that has grown Mercedes-AMG Petronas Motorsport’s social media community into the sport’s largest, at over 14 million people.
The Launch was held as part of the Team’s official 100 km Filming Day, during which the F1 W08 EQ Power+ completed its first laps on Silverstone’s 2.96 km International Circuit, in the hands of both Lewis Hamilton and Valtteri Bottas.

The all-new F1 W08 EQ Power+ has been designed to maximize the performance opportunities offered by radically different aerodynamic regulations for the 2017 season which will probably see the new cars become the quickest in the history of the sport – while leaving sufficient scope for an in-season development rate expected to be among the fastest ever in Formula One.
The M08 EQ Power+ is the fourth iteration of the Turbo Hybrid generation of Power Units and has been conceived to withstand significantly increased physical loads and a more severe duty cycle under the new rules, while also maximizing potential performance developments.

Upon unveiling the new car, Toto Wolff commented:
“The new rules for 2017 were designed to make the fastest F1 cars ever through a big increase in aerodynamic performance. They should be more physical to drive and hopefully more spectacular for the fans to watch. The proof will come in the opening races but we have probably achieved that target.
“Of course, in terms of relative performance, it’s clear that any rule change brings with it a big reset but also a big opportunity. This is the time to stay humble and keep our feet on the ground. None of the teams has raced under these rules and we all have the same points right now: zero.
“But the dominant feeling in the team right now is one of excitement – the factory is buzzing with anticipation. It has been a really motivating challenge to develop a brand new car concept and I have never seen our determination to succeed higher than it is right now.

A brand new technical challenge

In Formula One, major regulation changes have usually been designed to limit performance and provide the technical teams with new constraints to work within. The new rules for 2017 opened up a new and exciting challenge – the freedom to explore a more generous set of regulations, coupled with the uncertainty of not knowing exactly where targets should be set, or what will represent a good result.

If last year’s W07 was all about refinement and elaborate, detailed evolution, the W08 project has gone back to first principles. With the car having to be designed before running the definitive 2017 tyres, and in some parts before the regulations had even been finalized, it was important to arrive quickly at a sound base architecture, while following a flexible, adaptable philosophy to allow scope for major developments during the season. With this in mind, only 17% of the components in W08 have been carried over from its predecessor, with the team’s main focus lying on optimizing the car within the new aerodynamic regulations.

This is also the first major regulation change to occur under the Aerodynamic Testing Regulations (ATR), which limit every team to the same maximum amount of wind tunnel testing – 65 runs per week. Given the extent of the regulation changes, the first W08 concept ran in the team’s 60% Brackley wind tunnel before the first race of last season and has completed over 2,000 runs during its development so far.

In addition to the new shapes of front and rear wing, the biggest areas of aerodynamic opportunity are the floor and the barge board area in front of the sidepods, which have been the focus of significant work. And while the performance opportunity has been significant, the design teams have also worked to improve the W08 structurally in order to withstand the substantial increases in aerodynamic and mechanical loads.

 

The Power Unit, christened M08, has also been comprehensively redesigned for the new season. Although the previous token system did not constrain power unit development since 2014, its abolition allows the technical group more freedom for engineering solutions.
As ever, much focus has been on the primary energy conversion opportunity – the combustion process – but there are also many opportunities for gains further downstream, including within the engine ancillaries. The new aerodynamic regulations have had a significant impact on the configuration of the engine which, as a structural component of the car, must cope with significantly greater physical loads. To maintain its structural properties, the engine is therefore slightly heavier than its predecessor.

In addition to this comes an increased duty cycle, with the cars expected to spend approximately 10% more of every lap at full throttle – a change that is reflected in a 5% increase in race fuel allowance for the new season. M08 has also been designed for increased durability, with only four Power Units per driver per season permitted by regulation in 2017.
