Mild-hybrid power and refreshed looks give this SUV a new lease of life
Even in swoopy (or ‘mesmerising’, as Mercedes describes it) Coupé form and sporting AMG Line trim, the Mercedes-Benz GLC excels in refinement over dynamism, particularly thanks to its well-equipped, luxurious interior.That should suit this latest 300 4Matic model, which features an on-trend mild hybrid powertrain with a 14bhp 48V belt-driven starter-generator to aid the 255bhp 2.0-litre four-cylinder turbo petrol engine. It promises a boost in fuel economy, the ability for engine-off coasting and a bit of extra propulsion under acceleration – and a small step into electrification for the GLC ahead of the 300e plug-in hybrid.The reworked engine ties in with a general mid-life facelift for the Audi Q5 and BMW X3 rival, and while the exterior updates are subtle, particular attention has been paid to upgrading the on-board technology. The GLC has gained the latest version of Mercedes’ MBUX infotainment system and a number of new driver assistance features. But are those tweaks enough to make the GLC 300 a more compelling choice than before in the crowded premium family SUV market?
