After four years in production, the W205 Mercedes-Benz C-Class is finally receiving a facelift, in time for the Geneva Motor Show next month. Stuttgart has released the first photos and details of the revised compact executive model, which comes with a redesigned exterior and interior, a new electronic architecture from the also-facelifted S-Class and new engines.

From the outside, the C-Class gets a new front bumper that is rather reminiscent of full-on AMG models, with a slim centre air inlet situated underneath a larger full-width intake. Meanwhile, AMG Line models receive a grille with chrome diamond pins as standard, along with a wider centre air intake and vents ahead of the front wheels. Also new is the optional Multibeam LED headlights with 84 diodes and Ultra Range high beam, along with C-shaped light guides in the LED tail lights on the sedan models.

Inside, there’s a new infotainment system from the facelifted S-Class, incorporating a widescreen centre display and a digital instrument cluster with three display modes. Oddly enough, it doesn’t feature the new Mercedes-Benz User Experience (MBUX) as seen on the new A-Class, and is still controlled using the familiar COMAND rotary knob instead of a large touchpad as with the smaller model.

However, the steering wheel now features touchpads for controlling both displays, and the optional centre console touchpad now features haptic feedback. Also new is the magma grey/black interior colour scheme, as well as saddle brown for AMG Line models. There’s also the new Energizing comfort control system that links the climate control, air fragrance and seat heating, ventilation and massage functions.

Also borrowed from the facelifted S-Class is a range of new driver assistance systems, including the Distronic adaptive cruise control that can now utilise map information to proactively adjust the speed, such as when approaching bends, junctions or roundabouts. Active Lane Change Assist and Active Emergency Stop Assist have also been added, allowing the C-Class to drive semi-autonomously in certain situations.

Mercedes is keeping mum on what’s under the bonnet, merely saying that the facelifted C-Class will debut with new-generation petrol and diesel engines. However, it will almost certainly feature the new M264 2.0 litre turbocharged petrol engine that is already seeing service in the new A-Class in 224 hp/350 Nm A 250 guise.

The engine is also available with an EQ Boost 48-volt mild hybrid system, which in the E 350 Coupé and Cabriolet makes 299 hp and 400 Nm of torque and comes with an extra 14 hp on demand thanks to the electric motor. On the diesel side, the OM654 2.0 litre mill, replacing the OM651 2.2 litre oil burner, can already be found on the E-Class and is available in 150 hp/360 Nm 200 d and 194 hp/400 Nm 220 d tunes.

Also set to power the facelifted C-Class is the M256 3.0 litre straight-six petrol engine, also with EQ Boost – in the latest S 450 and CLS 450, the engine makes 367 hp and 500 Nm and gets an additional 22 hp from the electric motor. Further up the range, the same mill with 435 hp and 520 Nm is expected to be found in the new AMG C 53, which will replace the current 362 hp C 43.

At the top of the range will sit the AMG C 63, which is rumoured to gain new turbochargers on its 4.0 litre biturbo V8 to push outputs beyond the 476 hp and 650 Nm on the outgoing model (510 hp and 700 Nm on the C 63 S). Whatever engine you choose, a nine-speed 9G-Tronic transmission is expected to remain standard on all but the most basic of models.
