The new model, Mercedes’ global best-seller, has a dramatic new look inside and out, a 100kg weight reduction and a more efficient engine line-up that includes a model with sub-100g/km CO2 emissions for the first time in the fiercely contested compact premium saloon segment.
Other features of the new W205-generation C-class include the option of air suspension (another segment first), a more agile chassis, greater use of aluminium in its structure and a whole suite of advanced driver-assistance systems shared with the recently-launched new Mercedes-Benz S-Class.
Underpinning the C-class is the new lightweight modular rear-drive MRA (Mercedes Rear-drive Architecture) platform that will underpin all core rear-drive models from the C-class and above, including saloons and SUVs.
This new platform will be rolled out across a C-class line-up that will extend to include estate, coupé and AMG variants as well as a new cabriolet version and 4Matic all-wheel-drive models that will be sold in the UK for the first time from the end of next year.
The new C-class is 4686mm long, 1810mm wide and 1442mm high, the length and width growing by 95mm and 40mm respectively over the current car and the height reducing by 5mm. The wheelbase is up by 80mm to 2840mm.
The increase in size is due to the recent arrival in Mercedes’s line-up of the Mercedes-Benz CLA, a model that closely matches the current C-class in length. The fifth-generation C-class has thus grown longer and wider to distance itself from the CLA.
Visually, the new C-class shows a clear family resemblance to the latest S-class and recently revised Mercedes-Benz E-Class, as well as the smaller A-class family. Following Mercedes’ ‘sensual purity’ design theme, the fundamental classic rear-drive saloon proportions, including a long bonnet and set-back cabin, remain, but the Mercedes design team, headed by Gorden Wagener, have reduced the overhangs, raised the beltline, narrowed the glasshouse and added sculpted, flowing lines and surfaces that taper back to give a more classic profile inspired by the Streamliner models from the 1920s and 1930s.
This ‘soft’ treatment, which includes front and rear ends that avoid sharp edges and creases by curving into the car’s sides, contributes to the C-class’s class-best drag coefficient of 0.24.
