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 To achieve high engine speeds, the mechanical valve springs have been replaced by pneumatic valve springs.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.

Audi Aicon

 Aicon: Audi technology demonstrator

Design study, technology demonstrator, mobility concept: The Audi Aicon exploits every possibility offered by a autonomous luxury sedan of the future with unprecedented consistency. As a design study, the four-door 2+2 boldly leaps ahead to show the exterior and interior design of the next decades. The technology demonstrator combines innovations relating to the drivetrain, suspension, digitalization and sustainability in a visionary manner. And as a mobility concept, the Audi Aicon shows the world of tomorrow, in which the advantages of door-to-door individual transportation are combined with the luxurious ambiance of a first-class airline cabin.
Pure presence – the exterior

Design

The Audi Aicon looks spectacular from any angle. Its sheer size – an exterior length of 5,444 millimeters (17.9 ft), a width of 2,100 millimeters (6.9 ft) and a height of 1,506 millimeters (4.9 ft) – places it in the automotive top tier, the D segment.The designers reduced the front and rear ends to a minimum of lines and focused on large, uninterrupted surfaces. As with the Audi e-tron Sportback concept, the Aicon front features the inverted hexagonal Singleframe, a typical feature of the upcoming generation of electric cars from Audi. The sharply inclined silhouette of the entire front end evokes a sense of forging ahead – this, too, is a typical sports car body line.

 

Emotion and information – the LED lighting technology

Conventional headlights and lighting units are absent from both the front and rear of this car. Instead there are fully digital display surfaces comprising hundreds of triangular pixel segments. They are three-dimensional recreations of the Audi AI symbol. Grouped around the Singleframe are large light fields, in which – as at the rear – more than 600 3D pixels are arranged in space. The large surfaces and high pixel count enable versatile graphics, animations and information visualizations in any color. The Audi Aicon is thus no longer bound to a daytime running lights look, but rather can adapt to the driving situation and even its passengers. The customization is boundless. Horizontally cut lighting segments to the left and right of the Singleframe look like eyes and can be expanded to resemble wide pupils or squinted for an aggressive look. If the car detects passers-by or other road users, it literally makes eye contact with them and follows them with its “eyes.”

Accommodating – operation and communication

The oft-cited paradigm change in the automotive world – it shows in the Audi Aicon. One glance is all it takes to realize that all of the controls and displays are missing. Steering wheel, pedals, groups of buttons and instruments – nothing. Instead just wide, uninterrupted surfaces. The interior quickly comes to life once passengers enter. Illuminated lines of LEDs set colorful accents in the area of the doors. The front display lights up with a welcome message. PIA, the empathetic electronic vehicle assistant, recognizes the passenger by his phone and activates all of his personal settings. There are custom settings for the air conditioning and seating position, interior light color and the layout of the infotainment system. The navigation system awaits entry of a destination, and all accessible channels of communication are ready for use, connected via the fastest available standard.

New are the variably positionable control interfaces in the encircling door rail. Depending on the position of the seats, which can be shifted by up to 50 centimeters (19.7 in), ergonomically perfectly positioned touch and display elements are available in the digitized wrap-around. Your hand instinctively finds its way to the touch-sensitive control panels.

There are multiple input modes available for engaging with the car. Besides the haptic-manual layer, there are also voice control and eye tracking, in which sensors in the front end of the interior track where the passenger is looking.

The full range of services offered by modern communications electronics are available at all times in the Audi Aicon. Travelers can relax and watch a film or surf the web. Video conferences are another option, as is interaction on social media. Depending on the seating position, the passengers can use the large front display as the output surface or a virtual head-up image displayed above it in the windshield.

The glass roof panels can block out the sunlight, if desired. Their transparency level changes upon application of an electric voltage. Integrated OLED lighting elements allow for precise mood lighting or the even illumination of the interior when getting in or out of the car, for instance.

The Audi Aicon opens up a new world of mobility to its passengers. Freed from the tasks of driving, they can choose how to spend their time in the car. Working, communicating or simply just relaxing and even napping: Anything is possible while the car autonomously and safely finds its way.

Power unit

A highly efficient electric drive provides for the dynamics of the Audi Aicon. A total of four electric motors are located in the area of the front and rear axles. The energy storage units are integrated into the area below the floor. The four electric motors produce a total of 260 kW and 550 Newtonmeters (405.7 lb-ft). Each drives one wheel, enabling electronically controlled, variable quattro all-wheel drive. Maximum acceleration played a less important role in the specification than maximum efficiency and thus also range.

This operating strategy is also pursued by the powertrain and electric brake units, which use recuperation to recover energy. Targeted lightweight construction of the multimaterial body and optimized aerodynamics also help the Audi Aicon to achieve ranges between 700 and 800 kilometers (435.0 - 497.1 mi) on a single charge.

Even charging has been reduced to a minimum. Thanks to a high-voltage system with 800 volts, the Aicon’s battery unit can be charged to 80 percent of capacity in less than 30 minutes. The car is also equipped with a unit of inductive, i.e. wireless, charging. The Aicon manages both without a driver. In an AI Zone, it can pull up to a charging station on its own and charge its battery without any human assistance.

As a true quattro, the Audi Aicon offers ample performance and even autonomously always reaches its destination safely regardless of the weather or road surface. The suspension is designed for maximum comfort. Pneumatic spring and damper units smooth out any road surface irregularities.

The Audi Aicon is an all-arounder well prepared for its primary task: to offer a maximum of comfort, communications technology and freedom for its occupants during a long journey. It combines the scopes for autonomous driving in an urban environment and on the highway with an unprecedented range for an electric drive. The Aicon will be followed by further multitalented Audi models, each with their own specialized discipline, ensuring that the vehicle range of the brand with the four rings remains as diverse as it is fascinating.
