2027 Mercedes-Benz GLC facelift: star-motif lights, MB.OS, AMG inline-six hybrids

Mercedes-Benz tests the refreshed 2027 GLC with star-motif headlights, MB.OS-powered MBUX, and AMG inline-six hybrids; Euro 7-ready powertrains and PHEVs.

Mercedes‑Benz is testing the refreshed 2027 model‑year GLC, and the camouflaged prototypes already reveal the headline change: the brand’s star‑motif light signature first seen on the new CLA. For now, the updates are concentrated up front with reworked headlights, grille, and bumper. At the rear, judging by the first images, the new lighting appears slated for a later phase.

The cabin is in line for a tech lift as well. The GLC is expected to adopt the fourth generation of MBUX running MB.OS with an interface similar to the CLA’s, including a large 14‑inch central display and an optional screen for the front passenger. Features such as MBUX Surround Navigation and the advanced MB.DRIVE parking assistant are also anticipated, a combination that should modernize the cockpit and make daily use more intuitive.

The pivotal shift concerns the AMG versions. According to German media, the current GLC 43 and GLC 63 will be discontinued in 2026. They are set to be replaced by hybrid straight‑six engines from the M256 family, already used in the GT 43, CLE 53 and E 53 Hybrid, where total output reaches up to 604 hp. On paper, that direction feels like a better fit for the car’s character and market expectations.

Regular GLC and GLC Coupe models will retain their four‑cylinder engine lineup with MHEV and PHEV configurations. In Europe, the efficiency standout remains the diesel plug‑in hybrid GLC 300 de 4MATIC, rated at 0.45 l/100 km on the WLTP cycle and capable of up to 117 km of electric‑only driving—figures that are striking even by class standards.

All powertrains are being updated to meet Euro 7 requirements. Mercedes has also officially denied rumors about potentially purchasing engines from BMW.

The GLC continues to be Mercedes’ best‑selling model worldwide, and this refresh should bolster its standing as next‑generation rivals arrive. Focusing on signature design cues and deeper software capability looks like the right play.
