2021 Mercedes-Benz C-Class leaks online ahead of reveal
Audi A4 rival surfaces on social media, showing styling and interior inspired by S-Class

Mercedes-Benz is gearing up for an imminent unveiling of the new generation C-Class, but leaked images posted online give a good look at the final production styling and interior.

Pictures posted by The Automobolist Facebook page and CarsInPixels on Twitter show the C-Class will adopt a new look that brings it into line with the newer A-Class, E-Class and CLA. A more angular front end and reshaped light clusters are the most obvious evolutions, but more significantly it seems the BMW 3 Series rival will offer interior technology from the S-Class luxury flagship.

The infotainment system looks to have been completely reinvented to accomodate the firm's second-generation MBUX software, with the old car's horizontal central display swapped out for a prominent vertical item between the front seats. The rotary controller and physical gearshifter are gone, too, with their functions likely shifted onto the touchscreen or steering wheel, and the gauge cluster does away with its conventional rounded dials for what appears to be a fully digital set-up.

Elsewhere, we can see a new design for the C-Class' distinctive air vents, and that a colour head-up display will be available.

The new C-Class estate is not shown in the latest round of images, but was previewed earlier this year on a Youtube community post in a disassembled state at the factory. Like the saloon, it looks to feature familiar proportions and a new tail-lamp design, as well as interior influence from the recently launched S-Class.

The C-Class has been redesigned from the ground up, with highly efficient new hybrid drivetrains and advanced autonomous driving technology set to be some of its key draws.

Having experienced a sharp drop in C-Class sales in recent years because of the universal gravitation of buyers towards SUVs, the German maker is providing the fifth-generation model with many of the developments exhibited by the new S-Class. The new C-Class, codenamed W206, will challenge the Audi A4 and BMW 3 Series when it arrives in UK showrooms in the middle of 2021.

The starting point for the new C-Class is Mercedes' MRA (Modular Rear Architecture) platform. It offers a number of advances over the earlier version of the steel and aluminium structure. These include, according to insiders, more advanced electrical architecture that supports a 48V system, which is key to providing the 2021 model with a new range of plug-in hybrid drivetrains.

The AMG performance variants will make a return, but as revealed by Autocar, the top-rung C63 will swap its V8 engine for a new hybridised 2.0-litre four-cylinder unit with more than 500bhp.

The MRA structure uses a double-wishbone front and multi-link rear suspension, with adaptive damping likely to be offered as standard across the range in most markets, including the UK. The new C-Class will continue to provide the option of rear air springs on selected models.

As well as being used by the C-Class saloon, estate, coupé and cabriolet, the new platform will underpin successor models to the GLC and GLC Coupé, with a choice of both rear-wheel drive and optional four-wheel drive.

New all-terrain model

As an addition to the existing line-up, Mercedes has given the green light to a new Audi A4 Allroad rival in the C-Class All Terrain model. Based on the standard estate, it will receive more rugged styling, with unique bumpers and wheel-arch cladding, increased ride height and beefed-up underbody protection measures already brought to the larger E-Class All Terrain.

The engine line-up for the fifth-generation C-Class will consist primarily of four-cylinder petrol and diesel engines featuring a choice of EQ Boost mild-hybrid and EQ Power plug-in hybrid functions in combination with either a starter/generator or gearbox-mounted electric motor.

New electric motor and battery technology should increase the efficiency of future hybrid drivetrains, although the plug-in C-Class is likely to continue to offer the 31-mile range of the current C300de at the start of sales.

In a bid to make the new C-Class the most advanced car in its class, Mercedes will bring in the very latest autonomous driving features to set what one source involved in its development has described to Autocar as "new standards in human-machine interface in the automotive field".

Leading the push is a new Drive Pilot function with level three functionality. As pioneered by the seventh-generation S-Class, it will allow hands-off driving at speeds of up to 80mph for extended distances.

This brings a whole new range of sensor functions, including long-range lidar, multi-mode radar, the latest ultra-sonic sensors and a new stereo camera from Korean supplier LG.

It also provides the basis for a new level four automated valet parking function developed by Mercedes in partnership with Bosch. It allows the new C-Class to negotiate parking garages and manoeuvre into free parking spaces – all via a smartphone app interface.

Advanced adaptive cruise control will allow the C-Class to follow the car ahead at speeds of up to 130mph, slowing down automatically when speed limits change. It will also support the usual active lane change, lane keeping, emergency stop and brake assist with cross-traffic functions.
