The new C-Class: Saloon and Estate
Would you have known that…
… in the last decade, the C-Class was the highest-volume Mercedes-Benz model? Since the introduction of the still current generation in 2014, over 2.5 million Saloon and Estate models have been sold. All in all, over 10.5 million Mercedes-Benz cars in this category have been delivered to customers since 1982.
… China has been the largest sales market for the C-Class Saloon since 2016? In addition, the USA, Germany and Great Britain have been the largest sales markets for the C-Class Saloon and Estate models in the last ten years. Two out of every three C-Class cars sold in Germany are the Estate variant.
… both the front and rear passengers benefit from the moderately increased exterior dimensions of the new model generation? Elbow-room has been increased by 22 mm in the front and 15 mm in the rear over the previous model. Headroom in the rear has increased by 13 mm (Estate: 11 mm). Thanks to up to 35 mm more kneeroom in the rear, journeys are even more pleasant for passengers in the rear.
… the C-Class has taken another major step forward with respect to digitisation and high quality? The interior now has highlights such as the display and operating concept adopted from the new S-Class, with a sporty interpretation. This is accentuated by another design feature: the dashboard and central display are slightly tilted towards the driver.
… domestic equipment and household appliances can be controlled using the “Hey Mercedes” voice assistant of MBUX? Thanks to the Smart Home function, they can be networked with the vehicle and controlled remotely.
… the light in each DIGITAL LIGHT headlamp is refracted and directed by means of 1.3 million micro-mirrors? The resolution is therefore more than 2.6 million pixels per vehicle. DIGITAL LIGHT with projection function[1] is available as an option. This system can make driving safer by projecting guide lines, symbols and animations onto the road.
… the turning circle is reduced by over 40 centimetres to under eleven metres with rear-axle steering? With this optional feature, the steering angle at the rear axle is 2.5 degrees.
Mercedes-Benz management about the new C-Class
“The C-Class is our bestseller at the heart of the global market”
“The letters C and S sit at opposite ends of the alphabet. However, in our portfolio they’re now moving closer together. The C-Class is already our best-selling saloon. Still, I’m certain our new C-Class will excite even more customers with a wide range of high-tech features derived from our flagship S-Class. With the latest generation MBUX, rear-axle steering and comprehensive electrification, our most successful model range will once again raise the bar as the most sophisticated offering in its segment.”
Ola Källenius, CEO of Daimler AG and Mercedes-Benz AG
“Our customers have always loved the C-Class, because it has always been top with regard to comfort and technology as well as to spaciousness and design. That is substantiated by over 10.5 million units sold since 1982. With the latest edition, we are taking the next logical step on our road to the digital and sustainable future with a host of innovations and cutting-edge digital elements. Be it the Saloon or the Estate model – our customers have the possibility to customise the C-Class in order to turn it into a personal comfort zone“.
Britta Seeger, Member of the Daimler AG and Mercedes-Benz AG Boards of Management, Marketing & Sales
“Driving on electric power in everyday life and using the hybrid powertrain on long distances: The new C-Class is flexible, saves resources and as a plug-in hybrid runs for more than 100 kilometres on electric power – a clear benchmark. This too is part of our Ambition 2039 on the road to climate-neutrality.“
Markus Schäfer, Member of the Board of Management of Daimler AG and Mercedes-Benz AG; Daimler Group Research and COO Mercedes-Benz Cars
“After its introduction in the S-Class, the second generation of MBUX already débuts in new C-Class. All the possibilities for intuitive operation and personalisation have been adopted, plus driver-orientation as a new feature specific to the model series: the dashboard and central display are slightly tilted towards the driver, underlining the sportiness of the C-Class as a first in a Mercedes-Benz passenger car”.
Georges Massing, Senior Manager Digital Vehicle and Mobility, Mercedes-Benz AG
“We have created the most stylish and exclusive C-Class ever applying our company’s style of ‘Sensual Purity’. We create desire through the aesthetic beauty of sensuous surfaces, perfect sporty proportions, and an extraordinary ambience in the interior“.
Gorden Wagener, Chief Design Officer of Daimler Group
“The new C-Class redefines its segment in several respects at once: the comfortable spaciousness in the rear, the interior ambience and the high-quality workmanship. Plus there are equipment and comfort features from higher categories such as, for example. the rear-axle steering or DIGITAL LIGHT.
“
Prof Dr Uwe Ernstberger, Head of S-Class and C-Class Product Group
Brief interview with Christian Früh, Chief Engineer for the Mercedes-Benz C-Class
“Superb innovations in every area”
Christian Früh has been the Chief Engineer for the C-Class since April 2009. A native of Heidelberg, he previously headed the development of the assistance systems and was project manager for the Mercedes-Benz SLR McLaren. Früh holds a degree in mechanical engineering after studying at the universities of Karlsruhe and Darmstadt.
Mr Früh, what’s your personal highlight of the new C-Class?
Christian Früh: For me, the highlights include the new plug-in hybrid generation with an electric range of around 100 kilometres (WLTP), nimble handling, and a user-friendly boot. We also pushed the limits with respect to driving dynamics and active safety: the new rear-axle steering opens up new dimensions in driving pleasure. But this is only the tip of the iceberg. If we go through the vehicle in detail, we find superb innovations and features for every taste wherever we look. And in the end, that’s what distinguishes the C-Class – you don’t (really) need any more car than this.
What was the main development focus?
And the new plug-in hybrids are a great step forward in sustainability?
Früh: Yes, because at around 100 kilometres, the electric range will be twice that of the preceding model. The additional electric output is 95 kW. The battery can be charged to 100 percent capacity in 30 minutes. For many of their journeys, our customers will never use the combustion engine. Depending on customer behaviour and route profile, the carbon footprint can be as good as that of a BEV – depending on the electricity mix, of course. Not forgetting the considerably improved daily practicality: Despite the higher nominal battery capacity of 25.4 kWh, the luggage compartment floor is level and offers more space than in the preceding model. However, not only the plug-in hybrids, but also the other engines are in line with our “Electric First” strategy. Because each model of the C-Class has an electrified hybrid powertrain.
You have a passion for skiing. After your active career on the German national freestyle team, you were approached by the German Skiing Association and nearly became a coach. This suggests that an Estate model would be the ideal C-Class for you?
Früh: (laughs) Yes, in 1990 I reached a point where I had to decide whether to make sport my profession or base my career on my university degree. Looking at it today – as Chief Engineer for the C-Class – there are certainly some parallels with being a coach: you have to lead and motivate the team, you are always measuring yourself against the best in the world, and you’re pleased when you achieve success, break records, arouse public interest and receive awards. And if you’re at the high level we’ve reached with the C-Class, you fight particularly hard for the last few percentage points of progress, like a competitive athlete. But to answer your question: yes, I’m a fan of the versatile Estate model, especially in combination with 4MATIC. And we may have a surprise in store for fans of sporty estate cars with striking looks and dynamic handling …
The new C-Class: Saloon and Estate
This is how inspiring the comfort zone can be
Stuttgart. Welcome to a new, even more digital and efficient world, and welcome home: the new C-Class stands for both, and in all respects creates a future-proof comfort zone in a time of worldwide transformation. As the first classic model series from Mercedes-Benz, the new C-Class is electrified throughout thanks to plug-in hybrids and mild hybrids with 48-volt technology and integrated starter-generator. Due to a high-efficiency battery system, it achieves an electric range of about 100 kilometres (WLTP[3]) as a plug-in hybrid. That is unprecedented in this category to date. It also sets standards with respect to sustainability. And because the C-Class is one of the company’s highest-volume model series, this systematic electrification has a correspondingly strong effect on our carbon footprint. Other technical refinements include optional features such as DIGITAL LIGHT and rear-axle steering. The Saloon and Estate models première together, can be ordered from 30 March and will arrive in dealer showrooms in summer 2021.
Design: Sensual purity with a sporty and elegant touch
The new C-Class already looks to be in motion at a standstill with its dynamic proportions, thanks to the combination of short front overhang, long wheelbase and rear overhang. The sporty bonnet with power domes accentuates this urge of forward motion. The windscreen and passenger cell have been moved to the rear for these classic proportions known in the industry as “cab-backward design”. The preceding model was already a great step forward in terms of a high-value appeal in the interior, and the new C-Class goes even further with respect to modern luxury. The interior adopts highlights from the new S-Class, adding a sporty touch.
Exterior design: Profile with attractive light effects
When viewed from the side, elaborately sculptured surfaces create unique light effects. Conversely, the designers have reduced lines to a minimum, which accentuates the so-called catwalk line or shoulder line even more. In the Estate model, the progressive roof line in combination with the inclined rear window adds a sporty touch without functional compromises. Other features producing the sporty, superior appearance include the wide track and the flush 17- to 19-inch wheels in modern designs.
The brand’s hallmark radiator grille characterises the front. All models feature a central star, with the design and character of the radiator grille differing in the details. The base model has a central star and louvres. In the AVANTGARDE line, there are additional decorative elements in the louvres, while the radiator grille and front apron feature chrome surrounds. The distinguishing feature of the AMG Line is the diamond grille with the star design in chrome.
The rear-end design is typical of a Mercedes-Benz saloon. The high-quality design of the tail lamps fascinates with an unmistakable day and night appearance. In the Saloon, the lamps for the first time have a two-piece design in the
C-Class, with the light functions divided between the side wall and boot lid lamps. Their precisely configured interiors also showcase the standard of particularly high quality in detail. Optional or line-specific trim in the rear bumper attractively rounds off the rear view. Three new paint finishes – spectral blue, high-tech silver and opalite white – have been added to the colour range.
Interior design: sporty touches thanks to the driver-centred design
The dashboard is divided into an upper and a lower section: into a wing-like section with new, flattened round vents reminiscent of aircraft engine nacelles, and into an opulent expanse of trim. The latter flows from the centre console to the dashboard without interruption. Driver-focus adds to the sportiness: the dashboard and central display are slightly tilted towards the driver by six degrees.
The driver area features a high-resolution LCD screen. It is free-standing, and appears to float in front of the wing profile and the expanse of trim. This sets the driver display apart from traditional cockpits with classic round dials. Customers have a choice between a 10.25-inch (26.0 cm) or a 12.3-inch (31.2 cm) version.
The paradigm change to digitisation is also obvious in the central display: the vehicle functions can be controlled using the high-quality touchscreen. Its portrait orientation is particularly advantageous for navigation. The touchscreen likewise appears to float above the expanse of trim. Like the dashboard, the screen is slightly tilted towards the driver. The central display has a screen diagonal of 9.5 inches (24.1 cm) as standard. A larger version measuring 11.9 inches or 30.2 cm is optionally available.
A high-quality chrome insert divides the centre console into a rear, padded section for the armrest and a front section in lustrous jet black. The seemingly free-floating central display rises smoothly and seamlessly from this three-dimensional surface.
The modern, highly reduced design of door panels frames both ends of the dashboard. The door centre panel with integrated armrest evolves from a vertical surface into a horizontal orientation. Reflecting the design of the centre console, the front section takes the form of a metallic high-tech element. It can be used as a grab or closing handle, and houses the power window controls. Another highlight is the floating control cluster, into which the door opener and seat adjustment controls are integrated.
The special design of the optional AVANTGARDE or sport seats of the new C-Class uses layers and enveloping surfaces to create a visual impression of lightness. The head restraints are a completely new design and are attached to the backrest with a sealed piece of trim under which the adjustment mechanism is located.
A dashboard covered with man-made leather and featuring nappa-look beltlines is available for the C-Class (optional equipment, standard with AMG Line). The range of available trim showcases innovative surfaces. These include new interpretations of open-pored veneers in brown tones and a black, open-pored wood veneer featuring fine inlays of genuine aluminium that follow the dashboard’s contours.
The driver display and media display offer a holistic, aesthetic experience. The look of the screens can be individualised with three display styles (Discreet, Sporty, Classic) and three modes (Navigation, Assistance, Service). In “Sporty”, for example, the colour red is predominant and the central rev counter has a dynamic design. If any of the lines are selected, the new C-Class is equipped with ambient lighting featuring optical fibres as standard.
Latest generation of MBUX: intuitively operated and learning
Like the new S-Class, the new C-Class is equipped with the second generation of MBUX (Mercedes-Benz User Experience). The vehicle interior becomes even more digital and intelligent, as both the hardware and software have made great strides: Brilliant images on the LCD screens make it easy to control vehicle and comfort functions.
The driver display and media display offer a holistic, aesthetic experience. The information is presented in a clearly structured way. Mercedes-Benz developed a new display aesthetic for the S-Class, which now is systematically used as the basis for other models.
The look of the screens can be individualised with three display styles (Discreet, Sporty, Classic) and three modes (Navigation, Assistance, Service).
- In “Classic” style, the driver is welcomed with a familiar display environment. The proven display with two tubes and changing content between them provides all the information relevant to the driver.
- “Sporty” is dominated by the colour red, with dynamic design of the central rev counter.
- In “Discreet” style, the content is reduced to what is essential. In addition, both screens can be shown in seven colour schemes with the ambient lighting. This makes for an impressive colour experience in the interior.
- In the new “Assistance Mode”, the traffic situation is shown in real time and supplemented with important displayed information.
The full-screen navigation was adopted from the S-Class, and gives the driver the best possible guidance on a journey.
Hey Mercedes: the increasingly sharp voice assistant
The voice assistant “Hey Mercedes” becomes more interactive and capable of learning by activating online services in the Mercedes me App. Moreover, certain actions can be performed even without the activation keyword “Hey Mercedes”. These include taking a telephone call. “Hey Mercedes” also explains vehicle functions, and, for example, can help when asked how to connect a smartphone by Bluetooth or where the first-aid kit can be found. “Hey Mercedes” is also able to recognise the vehicle occupants by their voices.
Smart Home: Mobile intelligence for maximum operating convenience from a distance
With the MBUX Smart Home function, the C-Class now becomes a mobile control centre for the home of many people. Because Smart Home refers to WLAN, sensors and actuators make the home increasingly intelligent and communicative: temperature and lights, shutters and electrical appliances can be remotely monitored and controlled. Motion detectors and window contacts inform the user of welcome or unwelcome visitors.
“Hey Mercedes, is there anybody in my home right now?” “I checked. The last movement detected was in the kitchen one hour ago.” This is how future conversations between the driver or passenger and the user’s smart home might go using the MBUX (Mercedes-Benz User Experience) voice assistant. At the market launch, the MBUX Smart Home function will support numerous devices offered by important smart home providers – corresponding contracts have already been concluded with Bosch Smart Home and Samsung SmartThings. Further providers will follow, and be announced at a later stage. Right from the start, Hey Mercedes understands queries and commands in four languages (German, Chinese, American and British English). One can address lamps, sockets, thermostats, shutters and blinds, motion detectors and door or window contacts, as well as temperature sensors. So the system can also answer this question: “Did I remember to turn the heating down?” Depending on the response and the thermostats installed in the home, it is possible to change the setting: “Set the temperature to 18 degrees in the whole house!” In this way, Smart Home integration into MBUX helps to reduce home energy consumption. It also enhances comfort, because the heating can also be remotely turned up again in good time.
Music streaming: millions of songs to choose from
With the “Online Music” service, Mercedes-Benz has now fully integrated the major music streaming services into the MBUX infotainment system. MBUX enables seamless access to the personal user profile at the linked music provider. This not only gives customers convenient access to their favourite songs and personal playlists, but also the opportunity to discover millions of songs and curated playlists. Operation is intuitive, using the MBUX voice assistant “Hey Mercedes” or touch controls on the steering wheel, or directly on the central display.
Other highlights
Augmented Video is available as optional equipment. A camera registers the surroundings in front of the vehicle. The moving images are shown on the central display. In addition, virtual objects, information and markers are superimposed on the video image. These include, e.g. traffic signs, directional arrows, lane-change recommendations and house numbers. This can make navigation much easier, especially in urban areas.
A colour head-up display can be ordered as optional equipment. The driver sees a virtual image measuring 9 x 3 inches (approx. 23 x 8 cm) floating above the bonnet at a distance of about 4.5 m.
A fingerprint scanner is located in an ergonomic position below the central display. This allows users to log into MBUX quickly, conveniently and securely. The reason being that personal settings and data such as favourites, most recent destinations, behaviour-based predictions, business calendar entries or emails are protected. Payment processes via Mercedes me are also reserved to authenticated users.
“Over-the-air” (OTA) updates: The software is always kept up-to-date
As soon as a new update from Mercedes-Benz becomes available, a message appears in MBUX. The update is downloaded and installed in the background. The user then has to agree explicitly to its activation again. In this way the vehicle is always up-to-date. Features which have not even been invented yet can also be installed by means of OTA updates in vehicles already sold. To transfer the data, Mercedes-Benz relies on mobile communications technology and the communication module installed in the vehicle due to the high security standard.
Another way to ensure an up-to-date and improved user experience is to book new functions in the Mercedes me Store, e.g. music streaming services or In-Car Office. Subscription services can also be renewed or newly added directly online via the Mercedes me Store.
Powertrain: systematic electrification of the modern four-cylinder engines
Thanks to systematic electrification and intelligent downsizing, the new C-Class sets new standards in efficiency. The engine range has only four-cylinder units from the current modular FAME (Family of Modular Engines) Mercedes-Benz engine family. Accordingly, the engine range plays a major role in the flexibility of the international production network, with needs-based electrification.
In addition to turbocharging, both the diesel and the petrol engines now have an integrated starter-generator (ISG) for intelligent assistance at low engine speeds as a mild hybrid of the second generation. This ensures outstanding power delivery. The ISG uses a 48 volt on-board electrical system that ensures functions such as gliding, boosting or energy recovery, and makes significant fuel savings possible. The engines also start very rapidly and comfortably as a result, so that the start/stop function is almost as imperceptible to the driver as the transition from gliding with the engine switched off to strong acceleration under engine power. When idling, the intelligent interaction between the ISG and the combustion engine ensures outstandingly smooth running.
First diesel with an integrated starter-generator
Spearhead of the efficiency improvement measures is the new OM 654 M with an integrated second-generation starter-generator (ISG). It has a 48-volt partial on-board electrical system. An energy recovery function and the ability to “glide” with the engine switched off make the engine even more efficient. Along with electrification, which also includes the use of an electric refrigerant compressor for the air conditioning system, the most important modifications that make an output of up to 195 kW plus an additional 15 kW from the EQ Boost system possible are:
- A new crankshaft increases the stroke to 94.3 mm and the displacement to 1992 cc (previously: 92.3 and 1950).
- The injection pressure is increased to 2700 bar (previously 2500)
- Particularly fast response times and uniform power delivery thanks to two water-cooled turbochargers, both now featuring variable turbine geometry.
- A sodium-filled cooling duct in each of the steel pistons. This helps to dissipate temperature peaks in the combustion cavity of the pistons.
In terms of exhaust gas aftertreatment, this most powerful of the four-cylinder diesel engines also takes things one step further. Its components include:
- a close-coupled NOx storage catalytic converter for reducing nitrogen oxides
- a DPF (diesel particulate filter with special coating for reducing also the amount of nitrogen oxides)
- an SCR catalytic converter (selective catalytic reduction with metered injected quantity of AdBlue®) and
- an additional SCR catalytic converter in the vehicle’s underbody, with a separately metered injected quantity of AdBlue®
Four-cylinder petrol engine also with a second-generation ISG
The four-cylinder M 254 petrol engine with a second-generation starter-generator with an additional output of up to 15 kW and 200 Nm more torque is also celebrating its première in the C-Class. Thanks to energy recovery and the ability to “glide” with the engine switched off, the petrol engine is highly efficient. In the M 254, Mercedes-Benz has for the first time combined all the innovations of the modular engine family of four and six-cylinder petrol and diesel units in a single engine. They include NANOSLIDE® cylinder coating, CONICSHAPE® cylinder honing (trumpet honing) and the exhaust aftertreatment system positioned directly at the engine.
A completely new feature is the segment charger with flow connection, an advancement of the twin-scroll technology for even more instantaneous response of the forced induction system. The completely newly developed segment turbocharger is a result of cooperation between Mercedes-Benz turbocharger developers and the Mercedes-AMG Petronas Formula 1 team. The technology transfer to series production sets new standards with respect to power combined with maximum efficiency. For short periods, the output of the C 300 (combined fuel consumption: 7.0-6.6 l/100 km, combined CO2 emissions: 159-150 g/km)2 can additionally be increased by up to 20 kW overboost.
Transmission: Automatic now standard across the board
The 9G-TRONIC transmission was developed further for adapting the ISG, and is installed in all C-Class models. The electric motor, power electronics and transmission cooler have now moved into or to the transmission. Previously required lines are eliminated, which offers advantages with regard to installation space and weight. In addition, the efficiency of the transmission has been increased. Amongst other things, the optimised interplay with the electric auxiliary oil pump reduces the delivery rate of the mechanical pump by 30 percent compared with the predecessor – good for efficiency. Furthermore, it uses a new generation of the fully integrated transmission control with multi-core processor and new design and connectivity technology. In addition to the increased computing power, the number of electric interfaces has been drastically reduced, and the weight of the transmission controls have been cut by 30 percent compared with the predecessor.
The 4MATIC drive system of the all-wheel drive models has been advanced. The new front-axle drive allows higher torque levels to be transferred with an ideal axle load distribution for driving dynamics. Moreover, this has a significant weight advantage compared to the corresponding component in the preceding series – a contribution to CO2 reduction. The technicians were also able to reduce the friction losses in the new transfer case. In addition, it also a closed oil circuit, and requires no additional cooling measures.
