Welcome home. The slogan for the new E-Class  can be taken literally. Just by getting in and closing the door, you  find yourself in a totally different world. Noise, stress and the rush  of everyday life remain locked outside, replaced by an overriding  feeling of comfort and relaxation. Elegant forms, fine materials,  attractive colours, comfortable seats and exquisitely designed details  create an atmosphere in which you immediately feel at home.
One of the key aspects the Mercedes engineers focussed on to create  this exceptional level of comfort was the new dimensional concept for  the body and the interior, which differs from that of the outgoing model  in many respects and thus allowed a new form of “spatial planning”.  More space equals more comfort was the principle the product planners  applied to design a body that is 16 millimetres longer, 10 millimetres  lower and 32 millimetres wider than previously. Measured against the  outgoing E-Class model, the wheelbase length has been increased by 20  millimetres to 2874 millimetres, which is a major factor behind the  enhanced ride comfort and interior spaciousness. This is highlighted for  example by the seat reference point, effectively the distance between  the front and rear seats, which is crucial in determining the space in  which the occupants are able to move: it measures 848 millimetres  (outgoing model: 838 millimetres) and is therefore on a par with the  level which, not so many years ago, was the standard for top-end luxury  cars.
The occupants also benefit from the new dimensions of the E-Class  when it comes to shoulder room and elbow width. Here the new Saloon  impresses by offering up to 51 millimetres more (rear elbow width) than  its predecessor, largely down to the wider body (+ 32 millimetres) and  the wider track (front + 23 millimetres, rear + 49 millimetres). The  effective headroom for the driver and front passenger has been increased  by ten millimetres compared to the previous E-Class and now stands at  1048 millimetres; rear headroom is now 972 millimetres – an increase of  eleven millimetres.
When it came to “spatial planning” of the boot, the Mercedes experts  focussed on the everyday qualities drivers expect from an executive  saloon. Hence the key criteria for the boot design were sufficient space  for safely stowing four people’s luggage, practical variability when  using the luggage compartment and excellent functionality for stowing  large and small items. As well as being evident in the bare figures, the  impressive end result can above all be seen when it comes to everyday  practicality. Compared to the predecessor model, the length of the  luggage compartment has been increased by 33 millimetres to 1177  millimetres, while the height has risen by 14 millimetres to 468  millimetres. The smallest luggage compartment width between the wheel  arches has been extended by 24 millimetres and now measures 1000  millimetres. Furthermore, the boot opening, important for loading, has  also been widened – by eleven millimetres to 500 millimetres.
In practice, these dimensions mean that there is now space for two  jumbo suitcases side by side on the flat load-compartment floor or for  four golf bags (including clubs). The overall boot capacity of 540  litres (as per the VDA measuring method) has been maintained despite the  far more extensive basic equipment package for the new E-Class. There  are 78 litres of stowage space available in the compartment beneath the  luggage-compartment floor. And the optionally available folding  rear-seat backrests allow Mercedes customers to increase the  load-carrying capacity depending on the transport task in hand as well  as producing a practically flat load bay. Standard-fit load-securing  rings enable items of luggage to be secured in place.
For fast and easy stowage of smaller items, Mercedes-Benz equips the  load compartment of the new E-Class with a robust bag hook and stowage  nets on the load compartment side panelling. One new addition is the  optional EASY-PACK load-compartment box, which attaches below the parcel  shelf. From here, the box measuring around 530 millimetres in width can  be pulled forwards and loaded with ease as it unfurls downwards and has  variable settings. The box has a maximum capacity of 55 litres and can  carry up to ten kilograms.
Wide choice of seats for business-class travel and wellbeingMany aspects of the multicontour seat for the new E-Class have been  further enhanced, prompting “Aktion Gesunder Rücken” (a German  organisation that promotes back health) to award the seat its coveted  seal of approval. Multicontour means that the occupants are able to  adapt the contours of the seat to suit their anatomy or personal  preferences. This is made possible by inflatable air chambers beneath  the seat padding. A new method for adjusting the side bolsters allows  the backrest width to be adjusted continuously variably by up to 45  millimetres on each side – in other words by a total of up to 90  millimetres.In the outgoing model, the maximum adjustment range was just  50 millimetres.
Another plus point of the new multicontour seat is the function for  pneumatically adjusting the seat cushion length. The front air cushion  increases the seat cushion length by up to 50 millimetres at the push of  a button, allowing occupants to relax their legs and ensuring good  blood circulation.
The likewise new active multicontour seat offers the same comfort  functions and more than lives up to its name: fast piezo valves at the  air chambers vary the inflation pressure and volume of the air chambers  in the backrest side bolsters depending on the steering angle, lateral  acceleration and road speed so as to offer the driver and the front  passenger even better support.This active function relieves strain on  the musculature and enhances well-being. Plus it improves safety as the  fast piezo valves allow the active multicontour seats to be integrated  into the PRE-SAFE®anticipatory occupant protection system (also see page  54): if the PRE-SAFE®control unit detects a critical driving situation,  it activates the air chambers in the backrests almost instantaneously.  These then envelope the seat occupants and provide them with support,  limiting the dangerous whiplash movements of the upper body in the event  of accident.
To ensure a relaxed and fatigue-free ride, the Mercedes engineers  have developed another special feature, available in conjunction with  the active multicontour seat, in the shape of a massage cushion in the  backrest. It consists of seven air chambers that are inflated and  deflated cyclically so that the passengers feel a pleasant rolling  movement across their entire back area. This movement stimulates the  musculature, boosts circulation and counteracts premature fatigue. The  massage mat operates independently of the contour and lumbar settings.
Further features of the active multicontour seat include a luxury  head restraint with moving side bolsters, which also incorporates  crash-responsive NECK-PRO technology.
Filled seat piping for a new comfort experience right from the offFor the E-Class, the Mercedes experts have further enhanced the  quality of a tried-and-trusted Mercedes concept: filled seat piping.  This is a special form of upholstery in which an additional layer of  foam is inserted under the fabric or leather cover. The soft upholstery  makes the occupants feel comfortable and relaxed as soon as they take  their seats in the car. The experts attach great importance to first  impressions, in this case the impression a person has when sitting in a  car seat for the first time. All in keeping with the “welcome home”  motto.
The design of the filled seat piping depends on the design and  equipment line: the base model and the AVANTGARDE line have seat covers  with horizontal contours, while the ELEGANCE line features vertical  contours, evoking memories of the equally famous and well-proven  Mercedes seat design from the 1960s and 1970s. In each case, the  manufacture of the filled seat piping is a complex process in terms of  both the craftsmanship and the upholstery technology required. Only  Mercedes-Benz uses this process
A newly developed moulded foam cushion effectively forms the seat’s  lower comfort zone. In the centre area, the Mercedes engineers have  increased the foam thickness by around twelve percent compared to the  outgoing model. Coupled with the overall softer feel of the material in  the seat centre, this design provides noticeably more comfort. In the  area of the side bolsters, on the other hand, the foam is harder so as  to enhance lateral support. In this way, the experts achieve an  excellent pressure distribution, which helps relieve the strain on the  spinal column and provides specifically targeted support for the pelvic  area.
Mercedes seat developers have always attached great importance to the  optimum distribution of the seat pressure as they view this as a key  requirement for a high level of long-distance comfort. Seat pressure  distribution is adjusted in eight different zones of the backrest and  seat cushion, based on carefully acquired empirical values. The  backrests of the front seats, for example, are divided into several  pressure zones: whereas the foam is soft in the area of the cervical and  lumbar curve, it is hard in the pelvic and shoulder areas, where  optimum support is required. On the seat cushion, the pressure gets  progressively lower between the hip and thigh areas – a key requirement  for comfortable, fatigue-free car travel.
The foam upholstery used for the front seat cushions is housed in  seat squabs with integral springing. Here a frame made partially from  high-strength steel forms a solid base. Special tubular sections and  energy-absorbing elements in the seat lining ensure that, in the event  of a side impact, the seats are able to absorb high forces and transfer  these to the side facing away from the impact.
Lumbar support as standard for healthy sittingBecause the human body is not designed to sit still for long periods,  it needs support at specific points. One example is the lumbar lordosis  – the area of the lower part of the spinal column where the backbone  curves forwards. This inevitably leads to a hunched sitting posture –  meaning that stress is exerted on one side
of the intervertebral discs. The lumbar lordosis therefore requires  support when sitting. Standard equipment for the driver’s seat in the  E-Class includes a lumbar support which provides ergonomic support for  the spinal column in the lumbar region. If the Memory function is  specified by the Mercedes customer, the two front seats are equipped  with electropneumatically adjustable four-way lumbar supports including  side-to-side adjustment as well as height and shape adjustment.
The front-seat backrests consist of steel frames with springing and  foam elements whose contours, like the seat surfaces, provide even  better lateral support. The backrest height has been increased by around  30 percent in the area at the top of the backrest to provide even  better support for the shoulders.
Natural materials and active ventilation for a comfortable seat climateWhen developing seats, the Mercedes experts do not merely think about  classic comfort features such as springing and damping. Moreover, they  look at the all-round wellbeing of the car occupants, including what is  referred to as seat climate. The materials and structure of a Mercedes  seat are designed to ensure wellbeing whatever the weather and  temperature outside. In the case of the E‑Class seats, this is achieved  thanks to the breathable material mix and the high-quality fabric or  leather covers. The fabric covers contain 25 to 30 percent wool – a  natural material which, unlike synthetic fibres, displays excellent  electrostatic properties and, moreover, outstanding moisture absorption,  which has a positive effect on the seat climate in high temperatures.
Even greater climate comfort is provided by the optionally available  actively ventilated front seats: four ventilators in the seat cushion  and in the backrest extract cool air from the floor area of the interior  and distribute it evenly through a ventilation tissue beneath the seat  surface. The mild airflow can prevent the car’s occupants from sweating,  even when it is extremely hot outside.
Multiple adjustment options for the ideal sitting positionAs before, the front seat height, cushion angle and backrest  inclination can be adjusted electrically, while adjustment of the  fore/aft position of the seat cushion is performed manually. Plus the  seats in the new E-Class have the largest fore/aft adjustment range in  this market segment: 277 millimetres. The individual seat position can  be adjusted in very small 4.5-millimetre stages and is therefore almost  continuously variable, whereas the backrest inclination is fully  continuously variable. This means that very tall and very short drivers  can adjust the seat so that all of the Saloon’s functions are within  easy reach.
Adjustment ranges of the standard-specification front seats:- Fore/aft adjustment277 millimetres
- Seat height59 millimetres
- Seat cushion angle4.5 degrees
- Head restraint height 85 millimetres; head restraint depth 45 millimetres
- Backrest angle110 degrees
The fully electrically adjustable seats for the driver and front  passenger, which Mercedes-Benz supplies as optional extras, are even  easier to use. In this case, the fore/aft position, seat cushion angle,  head restraint, steering column and
exterior mirrors can be adjusted by electric motors in addition to  the seat height and backrest angle. Three individual seat positions can  be stored if the Memory function is specified. In this case, a touch of a  button on the inner door lining is all it takes to move the seats,  steering wheel and exterior mirrors to their programmed positions  automatically.
Once the driver has removed the electronic ignition key from the new  E-Class, the steering wheel can be moved upwards to make it even easier  to get out of the car. The steering wheel then remains in this position  until the ignition key is re-inserted, providing the driver with more  legroom when getting back into the car as well.
Individual seats for the rear passengersFor the rear passengers in the new E-Class, Mercedes-Benz has  developed a system comprising two individual seats offering an all-new  comfort experience (optional). The soft foam upholstery used for the  seat cushion and backrest features distinctive contours and makes travel  on board the Saloon even more of a pleasure. These luxury rear seats  feature leather upholstery, a heating function and their own head  restraints as well as a centre console between them and a  through-loading feature allowing longer items to be carried in the boot.  The head restraints, adjustable for height and angle, have side  bolsters which improve lateral support for the head, allowing the  occupants to fully relax in any reclined position.
A spacious stowage compartment with two cup holders for various cup,  can or bottle sizes is located beneath the leather-trimmed armrest. And  the through-loading module can be equipped with an optional ski bag.
Climate control: THERMOTRONIC with three individual climate modesComfort is all about highly individual preferences. Which is why it  is important for cars to offer their occupants a wide range of  personalisation options. The new E-Class meets this requirement, not  only in terms of suspension tuning and seat adjustability, but also when  it comes to climate comfort.
The new E-Class marks the debut of a Mercedes-Benz-developed  automatic climate control system which, as well as being able to set  individual temperatures in three zones (for the driver, the front  passenger and the rear passengers), additionally offers what are  referred to as climate modes. This means that, if the optionally  available THERMOTRONIC system is fitted, the car occupants can choose  from “Diffuse”, “Medium” and “Focus” at the push of a button and thus  adjust the air quantity and air distribution to their liking without  having to leave the convenient automatic mode.
In “Diffuse” mode, for example, the THERMOTRONIC system operates with  a low air speed and distributes the air over a wide area so that there  are fewer draughts. This is the purpose of the automatically controlled,  upwards inclined diffuse nozzle in the centre of the dashboard. In  “Focus” mode, meanwhile, the air outlets in the centre area of the  dashboard are used for the most part, meeting the need for a direct flow  of a larger quantity of air.
Sophisticated sensors are another reason why the three-zone luxury  automatic climate control system does full justice to its name. These  ensure that the desired temperatures set by the occupants remain  constant: even the standard-fit THERMATIC system features two sensors  for the interior temperature, four sensors for measuring the temperature  of the air flowing out of the air outlets and one sensor for recording  the intensity and direction of the sun’s rays, while the THERMOTRONIC  system for the new E-Class additionally includes a dew-point/moisture  sensor and a pollutant sensor.
The dew-point sensor enables specifically targeted cooling and, if  required, reheating of the inflowing air, meaning that the air  conditioning operates even more economically. The pollutant sensor  senses when the carbon monoxide and nitrogen oxide concentrations in the  outside air are too high and, if the level of these pollutants  increases suddenly, closes the air recirculation flap automatically.
Finally, the THERMOTRONIC system is equipped with a separate control  panel at the rear of the centre console, allowing the rear passengers to  select their ideal temperature and – if required – adjust the air  quantity manually. This means they control the special booster in the  centre console, which offers five speed settings and, therefore, ensures  highly effective climate control in the rear of the car.
Another highlight of the THERMOTRONIC system is the residual heat  function: pressing the “Rest” button heats or ventilates the interior  for around 30 minutes when the engine is switched off.
The standard equipment package for the new E-Class includes THERMATIC  two-zone automatic climate control. With this system on board, the  driver and front passenger can set the desired temperature using the  rocker switches on the elegant control panel in the lower section of the  centre console. The OLED (organic light emitting diode) display  indicates the programmed levels. If automatic mode is deactivated, the  blower speed and air distribution can also be adjusted by rocker switch.  The “ZONE” function is new: at the push of a button, the temperature  settings are synchronised, and the level selected by the driver is  transferred to the front-passenger side.
Heating output of a modern family houseThe THERMATIC and THERMOTRONIC systems have received a boost in both  heating and cooling output. The heating output has been increased by  around ten percent to eleven kilowatts, equivalent to the power of the  central heating system in a modern family house. In the diesel models  and the four-cylinder models with direct petrol injection, a heat  exchanger with six integral PTC heating elements (PTC = Positive  Temperature Coefficient) is also activated when the outside temperature  falls below a certain level in order to supplement the heater heat  exchanger with an electrical output of around 1200 watts. The PTC  heating element is required because, due to their high thermal  efficiency, the sophisticated CDI and CGIengines are very economical on  fuel and, therefore, give off much less heat to warm up the coolant than  conventional engines when running under partial load.
An air-conditioning unit with an output of around 8.4 kilowatts –  some five percent more than the unit used in the predecessor model –  ensures rapid cooling of the interior. The air-conditioning compressor  is continuously variable, allowing on-demand, i.e. economical, operation  of the air conditioning. The control is provided by a solenoid valve  which varies the swept volume of the air-conditioning compressor. In the  E 200 CDI BlueEFFICIENCY model, Mercedes‑Benz uses an air-conditioning  compressor which is disconnected from the engine’s belt drive  automatically when no cooling power is required.
Fine-dust particulate filter fitted as standardA large, hermetically sealed fine-dust combination filter, fitted as  standard for the new E-Class, ensures that the air entering the interior  is clean. It is 96 to 98 percent efficient at filtering out particles  between five and ten micrometres in size and 100-percent efficient when  it comes to removing ten-micrometre particles. Thanks to its  activated-charcoal coating, the fine-dust combination filter can also  filter out gaseous substances which are the cause of unpleasant odours.  The filter is active on a permanent basis – even in air recirculation  mode.
Up to ten electric motors and 18 air outlets for excellent climate comfortThe cleaned air flows to the centrally arranged evaporator, which  cools and, therefore, also dries the air, depending on the temperature  set by the car’s occupants. The temperature is then controlled with the  help of the heater heat exchanger, which sets the desired outlet air  temperatures. There are up to ten electric motors in total, whose job it  is to control the cold and warm air flaps in the mixing zones as well  as the air outlets, meaning that practically every air outlet can be  regulated precisely as required. THERMATIC features 18 air outlets for  effective and uniform ventilation of the interior, while THERMOTRONIC  includes two additional rear outlets in the B-pillars.
As well as being more effective, the climate control systems for the  new E-Class are also audibly quieter than before. Newly calculated  cross-sectional areas for the air intake, the air ducts and the  air-conditioning unit reduce the noise level at maximum cooling output  by around three decibels (dB (A)), for example. In addition, the air  ducting has been lined with acoustic absorption elements and/or  sound-insulating foam.
Dashboard: technology and aesthetics in harmonyAttractive design, a pleasant feel and perfect ergonomics are the  three main attributes of the dashboard and the centre console in the new  E-Class – a harmonious blend that is one of the main factors behind the  feeling of comfort and wellbeing experienced when riding on board the  Mercedes Saloon.
As an option, the dashboard can be ordered with a two-tone design:  while the upper section and the centre console are finished in a darker  shade, the lighter contrasting colour used for the knee bolster, glove  compartment lid and tunnel makes these areas really stand out. The  surface of the dashboard is made from a polyurethane foam skin with  additional padding. This sophisticated production process allows both  small radii and precise edges, plus it ensures a pleasant feel. For  particularly discerning motorists, Mercedes-Benz offers a dashboard  trimmed in high-quality sheeting with fine topstitching for a perfect  finishing touch. This item is part of the Exclusive package (optional  extra), which also includes a fine Alcantara trim for the roof lining,  sun visors and pillar mouldings.
The dashboard incorporates an illuminated glove compartment with a  capacity of around 6.8 litres, which can be cooled by the automatic  climate control system. A twelve-volt outlet and a socket for connecting  an external audio device are also integrated. This is likewise the  location of the optional media interface for connecting an MP3 player.
One of the main aims of the Mercedes engineers – to fuse elegant  design with a pleasant feel – is reflected in the door panelling. They  achieve this aim by combining high-quality materials such as fabric or  leather and wood or aluminium with scratch-resistant plastic boasting a  new grain-effect finish. The wide armrests on the door panelling are  pleasingly soft to the touch and, therefore, exceptionally comfortable.  Here the designers have integrated the control panel for the power  windows, the locking/unlocking switch for the doors and the exterior  mirrors so that it looks elegant and is also easy to reach and use. In  addition to the expansive wood or aluminium trim strips at waistline  height and the optical fibres for the ambient lighting in the ELEGANCE  and AVANTGARDE models, the door panelling incorporates a second trim  level, adding a further elegant touch beneath the armrests.
Centre console as command centre for the infotainment and automatic climate control systemsThe centre console blends in harmoniously with the dashboard form and  colour concept. This is where the controls for the infotainment system  and the optionally available car phone are located, just below the air  outlets. Beneath these, the buttons for the seat heating, seat  ventilation, rear window blind, rear head restraints and other optional  extras are demarcated by a discreet chrome strip. The lower section of  the centre console houses the controls for the standard-fit automatic  climate control system.
A special paint has been used to treat the visible areas of the  buttons and controls, giving them a satiny shine and a soft finish. The  experts call this “soft-touch paint”. Together with the sophisticated  short-stroke buttons, which are easy to press and have very little  travel, this paint helps ensure a pleasant yet precise feel. They  buttons only need to be pressed once to activate or deactivate the  function in question, and they always make a soft “clicking” sound to  confirm that the desired function has been activated.
Every last detail designed for everyday practicalityA wealth of intelligently conceived details in the interior of the  new E-Class highlight the fact that the Saloon has been developed with  the customer and, therefore, everyday practicality in mind:
The front-passenger footwell incorporates a practical storage net  suitable for holding an atlas or map. Directly above this is an  adjustable plastic bottle holder.
In the ELEGANCE and AVANTGARDE models, two stowage boxes, each with a  capacity of around 2.6 litres and suitable for carrying smaller items,  are housed beneath the driver’s seat and front-passenger seat.
Additional coat hooks are built into the B-pillar trims.As part of the Sun Protection package (optional extra), Mercedes-Benz  supplies two-piece luxury sun visors for the driver and front  passenger, an electrically operated rear window blind, guided on the  C-pillars as in the S‑Class, and manually operated roller blinds for the  insides of the rear side windows. They cover over 80 percent of the  window area and, therefore, provide highly effective protection from the  sun.
Proven concept for intuitive and reliable controlThe aluminium controller on the centre console is one of the core  elements of the tried-and-tested control and display concept which  Mercedes-Benz first unveiled in the S-Class some years ago. It is based  on the conviction that technology is only perfect if people can  understand and master its use intuitively. To achieve this aim, the  Mercedes experts have defined four basic principles that underpin their  work:
1. Easy identification of the key control functions
2. Fast availability of the key spontaneous functions
3. Simple and intuitive control of the key functions
4. All the controls in the right place
Key features of the Mercedes control concept include special  hotkey-type buttons which provide fast access to frequently used  functions. This is why all the control and display elements that are  necessary or important during a journey are located in the cockpit, i.e.  in immediate proximity to the driver. These include the switches and  stalks for the lights, windscreen wipers, indicators and cruise control  (standard in models with automatic transmission).
Furthermore, in keeping with the “everything in the right place”  logic, the switches and buttons for the power windows, central locking  and exterior mirrors are where one would intuitively look for them: on  the doors. In other words, the driver does not need to learn anything  new and, when it comes to the controls too, feels at home immediately on  board the new E-Class.
Multifunction steering wheel with twelve buttonsAlongside the controller on the centre console, the multifunction  steering wheel is one of the main protagonists of the sophisticated  control and display concept. Its buttons are linked to the central  display in the instrument cluster and merely need to be tapped with a  thumb to gain fast access to a wide range of information displayed right  in front of the driver’s eyes. The driver uses the left-hand button in  horizontal direction to mark one of the main menus on the central  display and in vertical direction to select the desired submenu. Each  selection or setting is accepted by pressing the “OK” button, while the  “Return” button is used to return quickly to the next-highest menu  level.
The buttons on the right-hand side of the multifunction steering  wheel are used for adjusting the volume (vertical), activating the mute  function (middle) and using the car phone (horizontal). Beneath these is  an additional button for activating the LINGUATRONIC voice-operated  control system.
Cockpit with five circular instruments featuring a high-quality chronometer-style designThere are five instruments in the cockpit to provide the driver with  all the necessary information: speedometer (middle), rev counter  (right), clock (right), coolant temperature gauge (far right) and fuel  gauge (far left). Thanks to black-panel technology, the indicator and  warning lights assigned to the various circular instruments are not  visible during normal driving; the driver only sees these when the  ignition is switched on or if a fault occurs.
In the centre of the speedometer is a two-section central display.The lower section of the central display is used for displaying icons  that provide information about the status of the driver assistance  systems as well as digital readouts of the outside temperature,  transmission gear and transmission mode
(if an automatic transmission is fitted). One of the new features is  the fuel consumption and gearshift indicator (if the six-speed  transmission is specified), which informs the driver of the current fuel  consumption and at what point the next-highest gear should be selected  in order to save fuel and reduce CO2 emissions (also see page 89).
Large colour display for the infotainment functionsIn the centre of the dashboard – where it can be easily seen by the  driver and the front passenger – a large colour display in 16:9 format  provides information about all the infotainment system functions. There  are two versions of this sophisticated AM-TFT(Active Matrix Thin Film  Transistor) display available, depending on the equipment specified for  the E-Class: a 5.8-inch version for the Audio 20 and Audio 50 APSdevices  or a high-resolution 7.0-inch version for COMAND APS (also see page  82).
The controller on the centre console incorporates the main controls  for the infotainment systems and allows fast and easy access to the  devices’ clearly structured menus. This turn/push control can be moved  in eight directions: turning the controller selects the main menu and  submenus on the display, while pressing it activates or accepts the  displayed function or setting. The “R” and “C” buttons in front of the  controller are used to exit submenus quickly or delete entries.
As the infotainment control system has been designed redundantly, the  car radio, CD/DVD changer, telephone and navigation system can be  operated either using the controller or at the push of a button. This is  the purpose of the function buttons on the centre console, which are  positioned ergonomically so that the driver can reach them easily  without having to take their eyes off the road.
Car radio, CD player and Bluetooth interface as standardInformation, communication, navigation, entertainment – these four  aspects are now just as important a part of motoring as agile handling,  outstanding comfort or powerful engines, for example. Motorists can no  longer do without news, the telephone, navigation and music whilst  driving. This is why Mercedes-Benz equips the new E-Class with  sophisticated infotainment devices that deliver outstanding performance  and, above all, are easy to use. These are called Audio 20 CD (standard  equipment), Audio 50 APS and COMAND APS (optional extras).
All of the devices include speed-sensitive volume control, a keypad  for entering telephone numbers and radio frequencies, a colour display  in the centre of the dashboard and a Bluetooth interface to connect a  mobile phone to the hands-free system wirelessly. Eight loudspeakers  fitted as standard in the doors deliver superlative sound.
Features of the Audio 20 CDsystem, fitted as standard in the new  E-Class, include a CD player (with MP3 capability), a dual tuner for  FM/MW/LW/SW, automatic station search, RDS function (for FM reception)  and a 4 x 20-watt amplifier.
The AUDIO 50 APS infotainment system is an all-in-one device  featuring a combination of car radio, DVD player and Europe-wide DVD  navigation system. The radio functions and the options for linking with  other systems are the same as for the Audio 20 system. Mercedes  customers who opt for the version with integral six-disc DVD changer  also receive the LINGUATRONIC voice-operated control system.
COMAND APSwith even more functionsThe Mercedes-Benz-developed COMAND APS multimedia system includes a  DVD player for audio and video as well as a Europe-wide navigation  system whose data are stored on a 40-gigabyte hard drive, allowing  extremely fast access to the navigation data and, compared to DVD-based  navigation, even faster route calculations. The high-resolution map  appears on the 7.0-inch colour display in the centre of the dashboard  and provides useful additional information. By way of example, the map  shows the outlines of prominent buildings along the road to aid  orientation.
In addition, COMAND APS includes a Music Register for around 1000  compressed music tracks in MP3, WMA or AAC format, which can be  downloaded from PC memory cards. The system has a saved database  (“Gracenote”), enabling it to recognise music tracks played from a CD,  DVD or the Music Register and then display the title of the track and  the artist on the display. Mercedes-Benz combines COMAND APS with  LINGUATRONIC voice-operated control and a text-to-speech function as  standard, allowing the driver to listen to route-specific traffic  reports, SMS messages, address book entries or station names. New  traffic reports relevant to the current route are read out automatically  by the system.
Voice-operated control with whole-word voice input for navigation, telephone and radioMercedes-Benz, one of the inventors of modern voice-operated control  systems, has continued to further develop the LINGUATRONIC system in  recent years, meaning that the navigation system in the new E-Class can  now be controlled based on the principle of whole-word voice input: the  driver no longer needs to spell out the names of countries, towns or  streets, but is able to speak them as whole words. It is just as easy to  use the voice-operated control to select a radio station or an entry in  the phone/address book: all available or stored names can be called up  without the need for prior voice-input training.
As an option, Mercedes customers can combine the infotainment devices  that feature in the E-Class with further systems offering even more  information and entertainment:
The “Logic7″ surround sound system developed by Mercedes-Benz in  partnership with the audio specialist harman/kardon® provides  three-dimensional audio enjoyment noticeable above all by a natural  360-degree music experience in all seats. It makes no difference if the  music is played from a CD or a DVD or if the disc contains 5.1 surround  or normal stereo recordings. The music signals are distributed by a  610-watt amplifier that controls 14 high-performance loudspeakers.
A media interface in the glove compartment can be used to connect an  iPod, USB stick or other external audio devices to the infotainment  system in the new E-Class. All that is required for this is a suitable  cable from the Mercedes accessories range. The interface includes a  control unit that links the external music memory to the Saloon’s  on-board electronic and control systems. The advantage of this is that  the titles of the tracks stored on the iPod can be shown on the colour  display in the dashboard and in the instrument cluster, allowing them to  be selected almost effortlessly using the controller and the buttons on  the multifunction steering wheel. The battery in the audio device is  charged for as long as the portable music memory is connected to the car  via the media interface.
A separate DAB tuner (DAB= Digital Audio Broadcasting) and additional  aerials (optional) allow passengers on board the new E-Class to receive  digital radio stations in CD quality. The system switches to analogue  reception automatically when the DAB signal is too weak.
A newly developed Rear Seat Entertainment System with a DVD player  and two large colour displays (8.0-inch) in the rear of the front head  restraints makes the ride even more entertaining for the rear passengers  in the new E‑Class. The system also includes connection options for  external audio or video devices and for the integration of a TV tuner.  If COMAND APS is fitted, the DVD films and TV programmes (if the TV  tuner is specified) played by the COMAND device can also be viewed by  those passengers sitting in the rear seats.
