Interior and seats: Interior revolution

The interior of the A-Class is a completely new departure, and revolutionises the compact class from the inside with a new feeling of spaciousness. The unique architecture is particularly marked by the avantgarde design of the dashboard. For the first time a cowl above the cockpit has been completely dispensed with. As a result, the wing-shaped main body of the dashboard extends from one front door to the other with no visual discontinuity. The standard widescreen cockpit is completely free-standing. The sporty air vents in a turbine-look are another highlight. The front seats have comfort features available from higher segments, including seat climate control, massage function and multicontour seat.

The interior architecture and the control & display systems of the new A-Class are a USP in this segment. The dashboard is divided into two three-dimensional, horizontal sections: the lower section is visually separated from the main body of the dashboard by a "trench", and it appears to float in front of the dashboard. The optional ambience lighting enhances this effect, accentuating the free-floating impression of the substructure.

The lower section of the dashboard provides the basis for the turbine-look air vents and the completely free-standing widescreen display. This is available in three versions: with two 7-inch (17.78 cm), one 7 and one 10.25-inch (26 cm) or with two 10.25-inch displays. For the latter two variants Mercedes-Benz uses bonded glass technology. Integration of the air conditioning display into the central screen also considerably helps to maintain the clear line of the cockpit. The air conditioning is controlled by the horizontal rocker switches of the A/C operating unit or via the corresponding on-screen menu.

Thanks to the omission of a cockpit cowl, the main body of the dashboard with its trim extends from one front door to the other behind the seemingly free-floating widescreen. The trim elements are in a "wrap-around" design, and the choice of materials (e.g. open-pore wood) underlines the progressive, modern positioning as the top interior in this class.

The five round air vents have a new turbine look inspired by the world of aviation. Finely designed air vanes in a concentric arrangement create the impression of a jet aircraft turbine. In one equipment line the vent surround is colour-accentuated at the depth of the vent geometry, giving the impression of an afterburner. The air vents in the middle are driver-oriented, accentuating the sportiness of the interior.

The door centre panel transitions seamlessly into the armrest, underlining the sensual, flowing design principle. The newly designed 3‑spoke steering wheel, door handles, centre console and seats follow a modern design idiom. The ring-shaped, completely closed grab/door-pull handle is of unusual design and particularly ergonomic.

Ambience lighting: avantgarde light pattern

From 12 to 64 – with the generation change, five times as many colours are available for the ambience lighting of the new A‑Class. And it is not just the variety that has increased, as the emotive presentation also sets standards in this segment: the different colours are composed into ten colour worlds allow an avantgarde lighting display with spectacular colour changes.

The colour worlds can be matched to the different styles of the widescreen display if required, creating a harmonious overall impression. There are also lighting effects that customers can activate individually.

The avantgarde ambience lighting was already taken into consideration in an early development phase, and systematically integrated into the interior design. This is apparent e.g. in the area where the upper and lower sections of the dashboard come together. Thanks to a combination of indirect and direct lighting, a very special ambience is created here which might be compared to the night-time illumination of a historic building. The interior of the turbine-like air vents with galvanised surfaces is likewise emotively presented by the ambience lighting.

The interior lighting uses only long-lasting, energy-saving LED technology.

Seats: comfort features from higher vehicle classes

When developing the seats for the A-Class, Mercedes-Benz used computer-based comfort simulation for the first time in the compact segment. Before the first real seat is actually available, this allows reliable prognoses to be made about the future comfort impression of the seating system solely on the basis of CAD data.

At the same time, comfort features from higher vehicle segments made an appearance: on request, and for the first time in this model series, not only seat heating but also seat climate control and a Multicontour Seat package are available for the front seats. With the seat climate control, there is a radial fan in each seat cushion. The air taken in through the perforated seat cover flows through the seat structure and is vented downwards and to the rear. This surrounds the occupants with a pleasant flow of air. Even when the interior has been strongly heated up in hot weather, the seat climate control rapidly cools the seat surfaces by taking in cooler ambient air. The ventilation level is adjustable in three stages.

With the Multicontour Seat package, the side bolsters and lumbar support can be individually adjusted by an electrically driven pneumatic pump. A massage effect in the lumbar area is provided by air chambers which are inflated and deflated in a pulsing or wave-like motion when the function is activated.

A total of three different front seats are available for the new A-Class: in addition to the basic model there is the comfort seat with up to 20 adjustments and the sporty integral seat available in combination with equipment lines.

The rear seats have a 60/40 split as standard, and the backrests can be folded down accordingly. A rear seat backrest with a 40/20/40 split is also available for even more variability in conjunction with the lines. In combination with the Load Compartment package (optional), the rear seat backrest can be positioned more upright, e.g. to accommodate bulky boxes.
