Design study, technology demonstrator, mobility concept: The Audi Aicon exploits every possibility offered by an autonomous luxury saloon 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.
The central element of the exterior is the cabin. Large glass surfaces at the front and rear as well as the significantly convex side windows create a bright expanse of space for occupants. A distinct edge runs as a hard line along the side window surfaces of the Aicon back to the D-pillar – a first in automotive design. This line emphasises the car’s length and effectively reduces the apparent volume of the cabin relative to the overall body. The darkened side sills rise subtly towards the rear, making it seem like the car is ducking. The strongly flared wheel wells emphasise Audi’s quattro DNA while simultaneously building a bridge to the latest production creations from the Audi designers. Giant 26-inch wheels are placed as far outward as possible. They underscore the car’s impressive presence.
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 colour. 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.
The Audi Aicon supports its surroundings intelligently and uses animations on its display surfaces to warn pedestrians or cyclists of dangerous situations. Driving modes such as platooning, urban driving or driving at a walking pace can be visualized. Horizontal stripes of light move from the bottom up when the car accelerates and in the opposite direction during braking. Their speed increases or decreases in sync with that of the car.
Future cars will expand their sphere of communication to the surroundings. The Audi Aicon uses projector modules to illuminate the road and surroundings in high resolution and project signals onto the ground. This enables it to communicate warnings and vehicle information to passers-by with no direct line of sight to the car.
One thing that an autonomously driving vehicle of the future definitely won’t need anymore are long-range headlights. The Audi Aicon’s laser and radar sensor system also “sees” enough even in the dark, can reliably find the way and detects possible obstacles in good time. All this time the passengers can use the services provided by myAudi or even close their eyes for a while. When passengers exit the Audi Aicon in the dark, a “light companion” is activated: A mini-drone with a flashlight safely illuminates the user’s walking path.
The Audi Aicon features opposed doors that open to the front and rear. There is no B-pillar. The entire breadth of the interior is thus exposed to the passengers as they enter the car. In the interior, the lines of the decorative surfaces and functional elements are markedly horizontal. Becoming lighter from bottom to top, the interior reinforces the impression of unique spaciousness, and the lack of a steering wheel and a classic dashboard creates a sense of openness and expanse.
This is underscored by the large glass surfaces, the transparent roof and the low waist line. Not to mention the special geometry of the side windows. Their top half angles distinctly outward, so that the maximum width is at eye height. The interior appears to be particularly wide when the two individual front seats are slid all the way back. The Audi Aicon is a 2+2-seater. An upholstered, two-seat bench is integrated into the rear panel. The two front seats are designed for maximum comfort and optimal spaciousness. Passengers can slide them up to 500 mm back and forth between the forward and rear positions. The seats don’t slide on rails, but rather on a platform covered in high-pile carpet that can be moved longitudinally, and on which the passengers’ feet also rest. The platform height is variable, so that it can also be used as an ottoman for legs. The pitch of the seat cushions and backrests can be steplessly adjusted for a comfortable working or resting position.
The oft-cited paradigm change in the automotive world – it shows in the Audi Aicon. One glance is all it takes to realise that all of the controls and displays are missing. Steering wheel, pedals, groups of buttons and instruments – none of these are present. Instead just wide, uninterrupted surfaces. The passengers are enveloped by the gently curved armrest along the doors, which rises slightly from back to front. Instead of a dashboard in front of them, there is a generous shelf and the central display below the windshield.
The interior quickly comes to life once passengers enter. Illuminated lines of LEDs set colourful accents in the area of the doors. The front display lights up with a welcome message. PIA, the empathetic electronic vehicle assistant, recognises 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 colour 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 centimetres, 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. Passengers can set the most important settings by tapping with their fingers without having to sit up in their seats or leaning forward. Operation is also interactive. The PIA system is often one step ahead of the passenger and offers services before they actively chose them.
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.
The drive and the total vehicle have also been optimally adapted to this new world of mobility. 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. These are solid body batteries with considerably more energy capacity than lithium-ion batteries.
The four electric motors produce a total of 260 kW and 550 Nm. 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 optimised aerodynamics also help the Audi Aicon to achieve ranges of close to 800 km 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 smoothe out any road surface irregularities. And electric actuators at all four wheels actively counteract any body lean, whether when cornering, accelerating or braking. As a fully active suspension system, it also optimises the qualities of the adaptive air suspension. The Audi Aicon literally glides over even large potholes.
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.
