14C264_058

Mercedes-Benz Intelligent Drive: the intelligent car

It is the declared aim of Mercedes-Benz to make the highest standard of safety available to everyone. For this reason the Estate adopts almost all new assistance systems from the S- and E-Class, which have been enhanced with significant functions. The assistance systems increase both comfort and safety. Mercedes-Benz calls this Intelligent Drive.

14C264_088

The C-Class Estate is fitted as standard with ATTENTION ASSIST, which can warn the driver of inattentiveness and drowsiness.

It offers an adjustable sensitivity level and can provide drivers with information on their level of fatigue and the amount of driving time that has elapsed since the last break.

14C264_093

Also part of the standard equipment is COLLISION PREVENTION ASSIST PLUS.

In addition to the adaptive Brake Assist system, which helps to protect against collisions at speeds above 7 km/h, this system now features an additional function: when a danger of collision persists and the driver fails to respond, the system is able to carry out autonomous braking at speeds of up to 105 km/h (200 km/h in conjunction with DISTRONIC PLUS), thereby reducing the severity of collisions with slower or stopping vehicles.

The system also brakes in response to stationary vehicles at a speed of up to 50 km/h, and is able to prevent rear-end collisions at up to 40 km/h.

Mercedes-Benz C 300 BlueTEC HYBRID, T-Modell (S 205) 2014

New assistance systems with enhanced functions are optionally available, combining data from various sensor technologies as part of the Intelligent Drive concept to enhance comfort and safety:

  • DISTRONIC PLUS – relieves the burden on the driver in keeping a safe following distance
  • DISTRONIC PLUS with Steering Assist and Stop&Go Pilot relieves
    the burden on the driver in keeping a safe following distance, even in stop & go traffic. Steering Assist is new and helps the driver with lateral control of the vehicle, even in gentle bends, and offers a tailback vehicle following function.
  • BAS PLUS with Cross-Traffic Assist boosts driver braking depending on the situation, if necessary up to full brake application and, for the first time, can also react to crossing traffic and pedestrians.
  • Active Lane Keeping Assist warns of unintentional lane departures by means of pulsed vibrations of the steering wheel and in the presence of solid lane markings corrects the vehicle’s track with one-sided brake application. It now also intervenes with one-sided brake applications in the presence of broken lane markings if the adjacent lane is occupied by, for example, oncoming traffic, fast overtaking or overtaken vehicles.

Mercedes-Benz C 300 BlueTEC HYBRID, T-Modell (S 205) 2014

The multitude of optionally available assistance systems also include, among others

  • Active Parking Assist, which enables automated parking with active steering and brake intervention in both parallel and end-on parking spaces
  • Traffic Sign Assist with wrong-way warning function, which warns of speed limits and also alerts the driver to no-overtaking zones and noentry signs
  • Adaptive Highbeam Assist Plus, which allows the high-beam headlamps to be kept on permanently by masking out other vehicles
    in the light cone of the high-beam headlamps

Mercedes-Benz C 300 BlueTEC HYBRID, T-Modell (S 205) 2014

Airbags for safety

In addition to 3-point safety belts with pyrotechnical belt tensioning and belt-force limitation for driver, front passenger and those in the outer rear seats, numerous airbags serve to protect the vehicle’s occupants in an accident. These include:

  • combined thorax/pelvis sidebags for driver and front passenger
  • an optimised windowbag
  • sidebags for the outer rear seats (optional)
  • a kneebag for the driver

Under the microscope: body shell

Intelligent lightweight construction

Thanks to innovative solutions, the body shell of the new C-Class Estate weighs less, provides the basis for outstanding vehicle handling and best noise and vibration comfort with exceptional rigidity, and offers a high level of crash safety.

Lighter cars are more efficient. That is why Mercedes-Benz has substantially reduced the weight of the new C-Class Estate.

Thanks to intelligent and innovative lightweight construction, the aluminium-hybrid body shell as well as front wings, bonnet, liftgate, doors and roof panelling made of sheet aluminium weighs about 65 kilograms less that its comparable predecessor model.

This makes it the “lightweight-construction leader” in its segment.

Less weight pays dividends in multiple ways: fuel consumption drops by up to 20 per cent and at the same time it makes a lower centre of gravity possible, which results in noticeably sporty-agile vehicle handling.

 

Mercedes-Benz achieved this technological leap primarily through an entirely new design and the extensive use of aluminium, hot-formed steel parts and ultra-high-strength steels – an unusual combination in volume-production vehicles.

The proportion of these materials has therefore increased noticeably compared with the successful predecessor.

Previous model seriesnew C-Class

Ultra high-strength steels 3% (3%)    4%   (6%)

The body shell engineers achieved further benefits – both in terms of weight and as regards other important body characteristics – by means of an intelligent lightweight construction concept.

As part of this process, they have redesigned each detail optimally and not simply replaced steel with aluminium.

After all, the specification not only required a reduction in weight, but also called for a body shell which in many respects sets new challenging standards, with hitherto unprecedented performance in this segment – for instance the high rigidity at the load introduction points from the suspension to the body or in relation to the NVH (noise, vibration, harshness) characteristics. This is a major factor in optimising road noise.

 

New body shell concepts proved the most direct way of meeting these requirements. For instance, the designers exploited the greater design leeway offered by die-cast aluminium compared with steel.

The body consists, among other things, of eight large die-cast components. The same designers also managed to integrate and merge various elements into a single die-cast component, which with conventional design would have to be made up of several steel parts.

In this way a host of functions can be rendered in a single component and installation space put to optimum use. For instance, all shock absorbers at the front and rear of the vehicle are mounted on such rigid aluminium die-cast components.

 

The liftgate has an all-aluminium lightweight design. The die-cast inner component gives the liftgate outstanding strength and reduces the weight at the same time.

The design options of die-cast components allow favourable use of the installation space as well as the integration of reinforcements. The sheet metal panelling is welded by lasers.

 

Other design details include larger cross-sections as well as precisely calculated stabilising beads in the floor and bulkhead. High-strength adhesives are used extensively to firmly bond the parts, which in turn helps increase the rigidity of the body shell.

 

The body shell clearly exceeds the values for overall vehicle rigidity, which are traditionally outstanding for Mercedes-Benz, and set a new benchmark in this segment.

As a result, the ambitious goals regarding dynamic vehicle handling and noise level have even been exceeded.

Safety takes precedence

In keeping with Mercedes-Benz traditions, the body shell is designed for exemplary crash safety. The Estate not only meets all current national and international laws, but also all rating requirements as well as the more stringent internal Mercedes-Benz safety requirements, which are based on what actually happens in real-life accidents.

 

A high-strength safety passenger cell forms the core of this concept. It consists primarily of high-strength and ultra-high-strength sheet steel and sheet metal with graduated wall thicknesses designed to withstand specific local stresses.

Many segments consist of hot-formed steels, which as the result of this production process become very hard and less deformable.

 

The high-strength passenger cell is surrounded by specifically calculated deformation zones which have been extensively field-tested.

Thanks to optimised dissipation paths and a combination of aluminium die-cast parts and ultra-high-strength materials, this set-up achieves outstanding crash test results (e.g. Euro NCAP) and guarantees maximum occupant safety.

 

The crash structure of the front end basically comprises three components:

  • the front side members are bolted to the axle and engine mounts made of high-strength steel and extended towards the front and rear to specifically direct forces into the floor structure. In the case of a serious frontal collision, the subframe deforms in a defined manner in order to prevent intrusions into the passenger cell.
  • The geometry of the front-end main side members has been further enhanced as the middle impact level to improve crash kinematics. The “laser welding” joining technique used here for the first time enabled, among other things, reinforcement parts to be fastened on both sides. They are crucial factors in improving the rigidity. Impact-absorbing elements in the side member extensions projecting forwards towards the front wheels help cushion the frontal impact early on.
  • A third support structure above the front side members forms a second longitudinal plane to further increase deformation resistance in the event of a frontal collision.

A curved high-pressure hydroformed tube and aluminium cast consoles with additional struts, which have hitherto only been used in cabriolets, enclose the front module.

An additional strut made of high-strength steel between the damper dome and windscreen cross-member on the driver’s side distributes the load from forces in the upper side member plane and reduces steering and pedal intrusion in the footwell.

Reinforcement sections in the beltline area and at bumper level increase the rigidity and strength of the aluminium doors. The door handle areas are also protected by ring-shaped reinforcements.

The side wall structure is primarily reinforced with hot-formed ultra-high-strength materials.

This provides optimum occupant protection in the case of a side impact; the B-pillar design in particular makes an outstanding contribution in this respect. The front and rear end can be completely removed, making the vehicle easy to repair.

Under the microscope: Mercedes connect me

In online contact with the car

Mercedes-Benz will introduce a new package of services in Europe under the name “Mercedes connect me” with the new C-Class Estate.

Under the umbrella brand “Mercedes me” the Stuttgart-based premium automobile manufacturer bundles all existing and future service offers – easily accessible and available at all times on a digital internet platform.

The line-up can be accessed via a personalised Mercedes ID on the www.mercedes.me website.

“Mercedes me” also includes the new “Mercedes connect me” services. The “Mercedes connect me” services can be used via a KOM module with its own SIM card integrated into the vehicle.

The available services include accident, maintenance and breakdown management, among others.

Likewise, customers can connect to their vehicle from anywhere and at any time via “Mercedes connect me“ and, among other things, retrieve the fill level of the tank or start, stop or programme the auxiliary heating system.

Mercedes-Benz emergency call system

In an accident this service automatically connects the occupants with the Mercedes-Benz Emergency Call Centre and sends the position and the condition of the vehicle to the rescue operations centre.

It can then immediately dispatch a rescue vehicle. The system works automatically but can also be triggered manually.

The “Mercedes connect me” basic services comprise:

  • Accident management – after the Mercedes-Benz emergency call it connects to the Customer Assistance Center to make it possible to request additional optional aid in dealing with the accident, e.g. a tow truck.
  • Breakdown management – it provides technical assistance in the event of a breakdown. To this end it transmits the vehicle position and the condition of the vehicle to the Customer Assistance Center, which informs the Mercedes-Benz Service 24h. This allows the MercedesBenz Service 24h to provide fast and optimal help.
  • Maintenance management – the vehicle detects and reports pending maintenance need and sends the necessary data to the service outlet as the basis for preparing a service quote.
  • Telediagnosis – the vehicle detects the necessary replacement of diagnostics-capable wear parts and reports it to the dealer. The dealer contacts the customers to schedule a repair shop appointment. The previously transmitted data enables the repair shop to provide optimal assistance.

New C-Class awarded allergy label

Emphasis on clean air

Mercedes-Benz has been awarded the Seal of Quality of the European Centre for Allergy Research Foundation (ECARF) for its passenger cars. This makes Mercedes-Benz the only vehicle manufacturer to bear this seal.

The ECARF Seal of Quality is used by ECARF to designate products that have been scientifically tested and proven to be allergy-friendly.

Alongside comprehensive testing for inhaled and contact allergens, Mercedes-Benz has been testing the interior emissions of all its model series for 22 years now.

And a team of olfactory experts works to ensure that odours in Mercedes-Benz vehicles remain at a consistently pleasant level.

“We are delighted that the allergy-friendly nature of our Mercedes-Benz passenger cars has now been scientifically and independently recognised through the award of the ECARF Seal”, commented Dr Jörg Breuer, Director Certification, Regulatory Affairs & Environment at Daimler AG.

“Indeed, the constant improvement of air quality in the interior has for many years now been a key aspect of the development of components and materials for Mercedes-Benz vehicles.”

“In our estimation, Mercedes-Benz currently represents the benchmark in terms of allergen optimisation for vehicles”, according to Professor Dr Torsten Zuberbier, Director of the European Centre for Allergy Research Foundation (ECARF), which is based at the Charité university hospital in Berlin.

The new C-Class is the latest Mercedes-Benz model to have received the ECARF Seal of Quality. The conditions of certification have been met by all model series launched in recent years, from the A-Class to the S-Class.

The criteria behind the ECARF Seal are also included in the specifications book for all future Mercedes-Benz passenger car model series.

The emphasis on clean air applies for Mercedes-Benz in three particular areas: along with the avoidance of allergens, the concern is to reduce interior emissions and to keep odours at a consistently pleasant level. “We have been measuring the interior emissions of our vehicles since 1992 and have been able to make steady progress in reducing them”, according to Dr Breuer.

“We have a strict internal limit these days, which has to be met by all Mercedes-Benz passenger cars – by our compact vehicles and roadsters but equally by our large estates and SUV models.”

There are currently a dozen or more experts working in the development and materials technology area on the interior air quality of new models.

Over the course of the coming year, the team will also be moving into a new test centre at the Mercedes-Benz Technology Centre in Sindelfingen – a fact which also serves to emphasise the importance given to this topic.

Even in the early stages of the development of a vehicle, up to six years before it goes into production, the minimisation of interior emissions is a factor helping to define the materials concept.

As far back as 1996, Mercedes-Benz’s own internal standards set emission levels for materials used for components in the passenger compartment and boot.

Today designers and developers can make their choice from a database of around 8000 interior materials that have been approved by the specialist department.

Interior emissions: extensive testing of many components and all cars

Just before a new model goes into series production, its interior emissions are tested in a series of complex procedures. This type of analysis has been conducted by Mercedes-Benz since 1992.

Component assessment involves the testing of numerous parts from each equipment variant of a model series – door panels and seats as well as the roof liner and trim.

In order to ensure that a realistic impression is gained, the team do not use specially produced sample components but standard production components produced using the tools that will be subsequently used for series production.

The testing procedure prescribes adherence to the VDA 276 standard as laid down by the German Motor Industry Association – the components are stored and measured in a test chamber 1 m3 in size at a defined temperature, humidity level and air circulation rate. Air samples are then extracted and used to measure the quality and quantity of gaseous substances in the air.

The examination of the vehicle as a whole involves an even more complex process.

The necessary preparation of the vehicle alone, in other words the installation of the measuring equipment, takes the well-rehearsed team three quarters of an hour, while the measurements themselves last a full week.

The test chamber is lined with stainless steel in order to prevent it giving off emissions of its own.

Large radiant heaters are used to simulate the sun and heat up the interior of the vehicle, since for physical reasons emissions are greater under the influence of heat. The solar irradiance is measured by special devices called pyranometers.

Inside the vehicle, as many as ten sensors are used to record the temperature in various areas, for example on the top of the dashboard.

A rotating paddle stirs up the air inside the vehicle to ensure an even mix. Overall emissions within the vehicle are calculated with the help of a rack-mounted flame ionisation detector.

The rack projects into the vehicle interior over the opened window on the driver’s side, which has been made airtight and emission-neutral with the aid of aluminium foil.

If taking measurements according to test method FAT AK 26, for example, measuring can begin as soon as a temperature of 65 degrees Celsius has been reached at the level of the driver’s nose.

Samples of air are extracted from the interior and the air flow directed into a series of test tubes. The chemical composition of the evaporated substances is then analysed in the laboratory.

“We use different sampling techniques for the various categories of substance that we analyse”, explains Hartmut Kovacs, Design for Environment, Head of Interior Emissions at Mercedes-Benz. “All in all, we take more than 100 samples from each vehicle.” As well as the overall emissions, it is therefore also possible to measure the emissions of individual organic compounds.

The emissions experts also look at a vehicle’s propensity to fogging – in other words the creation of a film of condensable substances on a car’s windscreen: the measuring rack therefore also includes a cooled sheet of glass upon which these less volatile substances, if present, are deposited.

In addition to this static test, a further series of tests are used to evaluate emission activity in the interior of the vehicle while it is in use.

These tests take place with the engine running and the air-conditioning system switched on, with and without air recirculation.

A further touch involves the driver’s door being opened once during each measurement cycle to simulate the driver getting into the vehicle.

ECARF Seal: extensive allergen testing

“In our estimation, Mercedes-Benz currently represents the benchmark in terms of allergen optimisation for vehicles”, according to Professor Dr Torsten Zuberbier, Director of the European Centre for Allergy Research Foundation (ECARF), which is based at the Charité university hospital in Berlin.

In industrialised countries these days, allergic conditions are now the most common form of chronic illness.

In Germany, for example, around 30 percent of the population are affected. One in ten absences from work as a result of sickness is now attributable to an allergy.

But the pollen count is not the only problem to afflict motorists who suffer from allergies: emissions given off by the materials used in the interior or when contact surfaces are touched can also lead to a strong reaction, with symptoms such as swelling and inflammation of the nasal passage, hay fever or asthma.

But not in a Mercedes-Benz vehicle: numerous model series, from the A-Class to the S-Class and now also the C-Class, meet the criteria of the allergy label.

The conditions involved are extensive: numerous components from each equipment variant of a vehicle have to be tested for inhaled allergens, for example. Furthermore, the function of the pollen filter must be tested in both new and used condition.

And then there are tests with human “guinea pigs”. Driving tests, for example, were conducted with people suffering from severe asthma, with lung function tests providing information about the impact on the bronchial system.

In addition, all materials that might come in contact with the skin were dermatologically tested. So-called epicutaneous skin tests were undertaken with test subjects suffering from contact allergies in order to test the tolerance levels for known contact allergens such as chrome-nickel and various pigments.

This involved substances from the interior that were deemed to be potential allergens being applied with plasters to the skin for 72 hours and the reaction to them being evaluated after 48 and then 72 hours.

The air-conditioning filters also have to meet the stringent criteria of the ECARF Seal in both new and used condition: amongst other things the tests measure their retention efficiency with regard to dust and pollen.

The professional sniffers: tracking down pleasant smells

Ultimately responsible for ensuring that odour levels in Mercedes-Benz vehicles remain consistently pleasant is a team of olfactory experts.

Mercedes-Benz has carried out an odour test since 1992. The olfactory experts take a sample of every single material that is to be used inside a new vehicle.

They place this sample in a standard, odour-free preserving jar, which is then sealed and heated for two hours at 80 degrees Celsius.

This is the temperature that can be reached inside a car if it is left in the blazing sun. And it is a fact of physics that odours become stronger under the influence of heat. The testers than allow the jars to cool down to 60 degrees, ready for the “sniffing” to begin.

Each tester lifts the lid up slightly, smells the air inside the jar and writes down a mark for the strength and quality of the smell. The final result represents the mean value of all the marks.

The assessment scale corresponds to the German school grades system, i.e. from one to six. A grade-one odour is “imperceptible” (for example glass, metals, stones), while three indicates an “obvious and distinctive smell, but not unpleasant” and six is “unbearable”.

Everything in the grade range from one to three passes the test. Materials that fare worse cannot be used in the vehicle. It’s then up to the supplier to make improvements. If the material passes a re-test, that test result becomes mandatory.

In order to test the odour produced by the interaction of all the various materials, the experts quite literally stick their noses into the finished vehicle before it goes into series production.

Four of them jump in, close the doors and have a good sniff. The odour team also carry out an olfactometric test. For this, the interior of the vehicle – with all its doors and windows closed – is warmed up by large heaters.

Using a bag, the specialists take an odour sample of the ambient air inside the closed vehicle. This bag is then attached to an olfactometer, a special device for measuring smells, and diluted with pure, odourless air before being smelt by a group of test subjects.

New C-Class: Climate control system uses signals from space

A significant factor in the excellent air quality found in the interior of the new C-Class is the further developed climate control system.

The two-zone automatic climate control has separate settings for the left and right, THERMOTRONIC a further setting for the rear.

However, instead of channelling the air to the rear via an air duct as is customary, it has its own blower in the centre console. This lets rear-seat passengers set their own feel-good climate.

The THERMOTRONIC three-zone automatic climate control is optionally available, the only real such system in this segment. In addition to separate controls for the driver and front passenger, it provides the option of setting the temperature and air flow in the rear compartment.

It also offers a choice of three ventilation modes: Medium, Focus, Diffuse. In addition the system is equipped with a pollutant sensor that switches automatically to air recirculation mode – particularly useful, for example, when caught in a traffic tailback alongside trucks.

The new C-Class is the only vehicle in the segment to offer tunnel detection via satellite navigation.

On the basis of map information from the navigation system and the GPS location data, the system detects when the vehicle enters a tunnel.

It then automatically closes the air recirculation flap in order to prevent the exterior fume-filled air from entering the vehicle via the air vents. Once the vehicle has left the tunnel, the flap opens and fresh air can once again flow into the interior.

Another highlight for creating the feel-good atmosphere is the AIR-BALANCE package with active fragrancing, ionisation and even more efficient filtration compared with the standard model.

It was adopted from the S-Class, in which the AIR-BALANCE package only recently celebrated its world premiere.

The various fragrances available have been specifically developed for this purpose and, like the ionisation and filtration functions, tested by ECARF for their acceptability to allergy sufferers.

Ionisation is another component of the AIR-BALANCE package, with which the air from the air conditioning is conducted into the interior via the ioniser.

The ioniser generates oxygen ions by means of high voltage. The air ionised in this way can eliminate certain viruses, bacteria and spores.

At the same time the air can be freshened by an increased concentration of negatively charged oxygen ions. Both help to increase the well-being of passengers.

In tests undertaken with asthmatics, under the supervision of Professor Zuberbier, the test subjects reported a clear improvement in their well-being as a result of the ionisation process.
