The Mercedes A-Class Sedan

Here is Mercedes-Benz’s latest iteration of their A-Class Sedan and boy, does it look sleek. Known to have the best aerodynamic design in its class, the new A-Class Sedan will be built in both Mexico and Germany. Due to be shown in public at this year’s Paris Motor Show in October, Mercedes isn’t shy to reveal it first to the world online.

“Following the successful start of the A-Class, things at Mercedes-Benz are happening in quick succession with regard to the new family of compacts. In response to the wish of many customers, we now offer the A-Class for the first time also as a sedan car”, says Britta Seeger, Member of the Board of Management of Daimler AG, responsible for Mercedes-Benz Cars Marketing and Sales. “Anyone looking for a compact, sporty sedan with a separate boot now has a new attractive alternative. It will enable us to win new customers for Mercedes-Benz“.

The A-Class established today’s compact car segment of Mercedes-Benz in 1997 and since then more than six million compact car models have already been delivered worldwide. The A-Class Sedan as the seventh model further expands the range of compact cars from Mercedes-Benz. A logical addition, because with the C, E and S-Class, Mercedes-Benz has more premium sedan competence than most other manufacturers.

The key dimensions of the new A-Class Sedan:

• Length/width/height: 4549/1796/1446 mm
• Wheelbase: 2729 mm
• Boot capacity: 420 litres
• Headroom front/rear: 1024/944 mm
• Elbow room front/rear: 1457/1446 mm
• Shoulder room front/rear: 1400/1372 mm
• Effective legroom front/rear: 1062/861 mm

The A-Class Sedan offers great utility. That includes above-average shoulder, elbow and headroom plus the easy access to the rear. It is at the top of its segment with regard to rear headroom (944 mm). The boot holds 420 litres and was designed for practical usability. The boot opening is very large with a width of 950 mm and a diagonal of 462 mm between lock and lower edge of the rear window. This allows comfortable loading and unloading of larger luggage items.

World record defended: none is more aerodynamic

The new A-Class Sedan takes advantage of the favourable conditions provided by its long rear end to undercut even the already exemplary A-Class with hatchback (C_d value from 0.25). With a benchmark of C_d = 0.22 the new sedan model even equals the original world record of the CLA Coupé. Thanks to the frontal area of 2,19 m², smaller than that of the CLA, the new A-Class Sedan has the lowest aerodynamic drag of all production vehicles worldwide.

The good aerodynamic properties are a crucial factor in the low fuel consumption in real-life conditions. A host of details was optimised with numerous computation loops, CAE simulations (computer-aided engineering) and measurements in the wind tunnel in Sindelfingen. The measures also include an extensive sealing concept (with sealing of the headlamp surroundings et al.) as well as the nearly complete panelling of the underbody, which comprises the engine bay, the main floorpan, parts of the rear axle, the diffuser and other components. The front and rear wheel spoilers were optimised specifically to route the air around the wheels as efficiently as possible. The rims and tyres also underwent aerodynamic fine-tuning. Depending on the market, an optional two-part shutter system behind the radiator grille is available, which minimises the airflow through the engine bay.

Engines: start with one diesel and one petrol engine each

The following engines are available at the start of the A-Class Sedan:

• A 200 (120 kW/163 hp, 250 Nm); with 7G-DCT dual-clutch transmission (combined fuel consumption 5.4-5.2 l/100 km, combined CO₂ emissions 124-119 g/km)
• A 180 d (85 kW/116 hp, 260 Nm); with 7G-DCT dual-clutch transmission (combined fuel consumption 4.3-4.0 l/100 km, combined CO₂ emissions 113-107 g/km).

Equipment & appointments: KEYLESS-GO with HANDS-FREE ACCESS available

The entry-level model is already extensively equipped. Standard features include the MBUX – Mercedes-Benz User Experience infotainment system with touchscreen, and driving assistance systems of the latest generation such as Active Brake Assist and Active Lane Keeping Assist. In addition, the A-Class Sedan can be customised with the design and equipment lines Style, Progressive and AMG Line, the Night Package as well as further optional equipment.

The KEYLESS-GO Convenience Package with HANDS-FREE ACCESS will be one of the available options, for example. The HANDS-FREE ACCESS convenience function enables hands-free and fully automatic opening of the boot lid with a kicking motion of the foot under the rear bumper.

The A-Class Sedan will be available as an Edition 1 in the year of the market launch. This special model features a host of copper-coloured highlights in the exterior and interior.

Interior design: revolution from within

The interior of the new A-Class is completely redefined with its modern, avant-garde look. Mercedes-Benz has taken a completely new approach, revolutionising the compact class from the inside with a new feeling of spaciousness. The unique interior architecture is shaped in particular by the avant-garde design of the dashboard: The designers completely dispensed with a cowl above the cockpit. As a result, the wing-shaped main body of the dashboard extends from one front door to the other with no visual discontinuity. The Widescreen display (optional) is completely free-standing. The air vents in a sporty turbine look are another highlight.

Below this main body is a low-lying section, the so-called wing. The wing appears to float, as there are no connections or shape transitions to the surrounding area. The ambient lighting enhances this effect, accentuating the free-floating impression of the substructure. The 64 colours of the optional ambient lighting make five times as many colours available than before. 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 to allow an avant-garde lighting display with spectacular colour changes.

The fully free-standing cockpit is available in three versions:

• with two 7-inch displays (17.78 cm),
• with one 7-inch and one 10.25-inch (26 cm) display and
• with two 10.25-inch displays.

MBUX – Mercedes-Benz User Experience: unrivalled experience

The new A-Class is the first Mercedes-Benz model to feature the completely new MBUX – Mercedes-Benz User Experience multimedia system, which also ushers in a new era for Mercedes me connectivity at the same time. As a result, it also comes standard in the A-Class Sedan. A unique feature of this system is its ability to learn thanks to artificial intelligence. MBUX is customisable and adapts to the user. It thus creates an emotional connection between vehicle, driver and passengers.

Its further strengths include, depending on the specification, the high-resolution Widescreen Cockpit with touchscreen operation of the media display, the navigation display with augmented reality technology plus intelligent voice control with natural speech recognition, which is activated with the keyword “Hey Mercedes”. A head-up display is also available. The touchscreen is part of the comprehensive MBUX touch-control concept – a triad consisting of the touchscreen, touchpad on the centre console (optional) and touch control buttons on the steering wheel.

MBUX is a revolution of the user experience in the car. Emotively appealing showcasing features underline the comprehensibility of the control structure and thrill through brilliant 3-D maximum-resolution graphics which are rendered, i.e. calculated and displayed, in real time.

New and improved Mercedes me connect services are being launched with the new infotainment generation MBUX. These include the navigation functions based on Car-to-X Communication (information from vehicle to vehicle on events recorded by sensors, e.g. emergency braking, ESP^® intervention, or a manual system message from the driver, e.g. about an accident) and Vehicle Tracking, which makes it easier to find the parked car, as well as a message if the parked car has been bumped or towed away.

The Mercedes me app collection can be placed as an icon on the screen in a user-friendly way and can be freely sorted on the homepage like all other main applications. In addition, online content such as current filling station prices or the availability of parking spaces in the multi-storey car park are displayed in MBUX as an option. Online updating is a simple way of allowing new content to be made available in MBUX.

Intelligent Drive: functions from the S-Class

The A-Class has the very latest driving assistance systems with cooperative driver support, and thus provides the highest level of active safety in this segment with functions adopted from the S‑C lass. For the first time, the A-Class is able to drive semi-autonomously in certain situations. To do this, it keeps a close eye on the traffic situation: improved camera and radar systems allow it to see up to 500 metres ahead. The A-Class also uses map and navigation data for assistance functions. For example, Active Distance Assist DISTRONIC as part of the Driving Assistance Package is able to provide route-based support to the driver in numerous situations, and to predictively and conveniently adjust the speed, e.g. when approaching bends, junctions or roundabouts. Also on board are e.g. Active Emergency Stop Assist and intuitively understandable Active Lane Change Assist.

The new A-Class comes with expanded Active Brake Assist as standard. Depending on the situation, it can effectively help to mitigate the consequences of rear-end collisions with slower-moving, stopping or stationary vehicles ahead, and even with crossing pedestrians and cyclists, or prevent them altogether.

Active Lane Keeping Assist (likewise standard) is able to warn the driver by means of pulsed vibrations in the steering wheel when the vehicle is unintentionally drifting out of its lane at speeds between 60 and 200 km/h. If the vehicle passes over a solid line, it can pull the vehicle back into lane by applying the brakes on one side. In the case of a dotted line, such intervention takes place only when there is a danger of collision with a vehicle in the adjacent lane (including danger from oncoming traffic).

PRE-SAFE^® PLUS can recognise an imminent rear-end collision. If the danger of a collision persists, the system can also firmly apply the brakes of the stationary vehicle, thus minimising the risk of injuries by reducing the forward jolt caused by an impact from the rear.

Passive safety: highly stable passenger compartment and modern restraint systems

The new A-Class is also the first Mercedes-Benz model to have been developed at the new Technology Centre for Vehicle Safety (TFS). The design of the vehicle structures incorporates findings from research into real accidents. Every single body shell component was developed according to the loads and stresses encountered, with respect to geometry, material thickness, joining technology and material quality (increased proportion of high-strength and ultra-high-strength sheet steel).

The centrepiece of the body’s safety concept is the highly rigid passenger compartment. Its great rigidity when subjected to accident-induced stress e.g. in frontal, lateral or rear-end collisions and rollovers is above all due to the greater use of high-strength, ultra-high-strength and press-hardened sheet steel.

Driver and front passenger each have a three-point seat belt with belt force limiter and belt tensioner. In conjunction with the PRE-SAFE^® system (optional equipment), the front seats are equipped with reversible belt reel tensioners. Both of the outer rear seats are fitted with a seat belt with reel tensioner and belt force limiter. The new A-Class is equipped with driver and front passenger airbags, a driver’s knee airbag and window airbags as standard. Unlike in many competing models, the window airbag also covers the A-pillar for more complete passenger protection. Thorax-pelvis side airbags are likewise standard in the front, and available as optional equipment for the rear.

MULTIBEAM LED headlamps: optimum visibility in all conditions

The optional MULTIBEAM LED headlamps are another example of the technology transfer from the luxury to the compact class. They allow extremely quick and precise, electronically controlled adjustment of the headlamps to suit the current traffic situation. Each headlamp features 18 individually actuated LEDs. The daylight-like light colour of the LEDs is easy on the eyes and has a positive effect on concentration. The road ahead is precisely and brightly illuminated. LED High Performance headlamps are a further option. As standard, the new A-Class is equipped with halogen headlamps with integrated LED daytime running lamps.

Suspension: agile and comfortable

There is a choice of suspension systems for the A-Class, depending on engine variant and driver preference. The line-up of wheels ranges from 16 to 19 inches.

The front axle of the new A‑Class features a McPherson design. The more powerful versions and models with 4MATIC, adaptive damping or larger wheels are fitted with a complex four-link rear axle. The other models have a weight-optimised torsion-beam rear axle.
