February 23, 2021 - 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 ) 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.
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 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.
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 look of the screens can be individualised with three display styles (Discreet, Sporty, Classic) and three modes (Navigation, Assistance, Service).
The full-screen navigation was adopted from the S-Class, and gives the driver the best possible guidance on a journey.
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.
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.
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.
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.
Plug-in hybrids with an electric range of around 100 kilometres (WLTP)
Fourth-generation plug-in hybrids will follow soon after the launch. Electrification is taking a great step forward while using the same base engines. With an electric output of 95 kW (129 hp) and an all-electric range of around 100 kilometres (WLTP), the plug-in hybrid C-Class will operate in all-electric mode in many cases - and on many days without using the combustion engine at all. This is the two-litre variant of the ultra-modern M 254 four-cylinder engine. The complete package is not only very efficient, but also decidedly sporty. Diesel plug-in hybrid Saloon and Estate models will follow.
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.
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.
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.
