Mercedes' revised GLC and GLC Coupe will arrive next summer, with styling changes, fresh tech and overhauled engines
18 October 2018

Mercedes-Benz is putting the finishing touches to facelifted versions of its three-year-old GLC and GLC Coupe, with the more powerful AMG GLC 63 pictured here set to head the new line-up.

The reworked mid-sized Mercedes SUVs are planned to make their public debut at the 2019 Geneva motor show next March prior to a planned start to UK sales by the middle of next year, according to officials from the German car maker.

Among the styling changes adopted by the facelifted GLC Coupe are new LED headlamps and tail lamps featuring altered graphics and optional Multibeam projectors, reprofiled bumpers and a new range of alloy wheels ranging to 21in in diameter. 

Inside, there is an updated dashboard with digital instruments and Merc’s latest infotainment system – as seen on the recently unveiled GLC Fuel Cell and all-electric EQC. They feature elements of Mercedes-Benz’s MBUX control system launched on the fourth-generation A-Class earlier this year, albeit without touch control.

Further changes include a new wireless charging pad for smartphones, a more advanced speech control system, altered trims and ambient lighting options – both aimed at lifting perceived quality levels against increased competition from the likes of the second-generation Audi Q5, third-generation BMW X3 and recently facelifted Porsche Macan.

On the engine front, the GLC Coupe will receive new four-cylinder engines in the form of Mercedes' OM654 diesel and M264 petrol units – both with added performance and reduced emissions.

The 2.0-litre OM654 diesel replaces the old 2.1-litre OM651 engine, developing 192bhp in the GLC220d and 241bhp in the GLC300d for increases of 22bhp and 28bhp over today’s GLC220d and GLC250d respectively. Mercedes' new M264 petrol engine replaces the M274. In 2.0-litre form in next year’s GLC300, it provides an additional 13bhp at 254bhp.

Further up the line-up, the new GLC is set to offer the choice of two new plug-in hybrid drivetrains in diesel and petrol forms. They both provide electric ranges of over 50km together with combined average consumption and CO2 emissions on the WLTP cycle of less than 2.0L/100km and 50g/km.

The GLC300de uses a 192bhp version of the 2.0-litre OM654 four-cylinder diesel engine in combination with a 120bhp electric motor and 13.5kWh lithium-ion battery for an overall system output of 302bhp and 516lb ft of torque.

The GLC300e receives a 208bhp version of the 2.0-litre M264 four-cylinder petrol engine together with the same 120bhp electric motor and 13.5kWh lithium-ion battery as its diesel sibling for an overall system output of 316bhp and the same 516lb ft. Also planned is a slight power increase for the 3.0-litre V6 petrol engine in the GLC43. It is set to gain an added 23bhp, taking its output to 385bhp.

The GLC63 4Matic will continue to run a 4.0-litre V8 with either 469bhp in standard form or 503bhp in top-of-the-line S form. However, outright performance gains are promised through the adoption of a new nine-speed automatic gearbox in place of the seven-speed unit in use today.
