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.
