Mercedes-Benz has refreshed its GLE and GLS SUV lineup for 2027 with updated powertrains that emphasize smooth operation. The revision marks a significant update to these models, which sit below the flagship S-Class sedan in the brand's luxury portfolio.
The refreshed SUVs feature what Car and Driver describes as "near-seamless powertrains," indicating refinement in their power delivery systems. The publication tested both vehicles and found the updates give these models renewed appeal in the competitive luxury SUV segment.
The GLE and GLS serve different purposes within Mercedes' lineup. The GLE operates as a midsize luxury SUV, while the GLS positions itself as the larger, three-row variant. Both vehicles now incorporate the powertrain improvements that appear central to this model year refresh.
Car and Driver's road test concentrated on how these updates translate to real-world driving experience. The emphasis on seamless powertrain operation suggests Mercedes has refined transmission behavior, likely improving acceleration response and shift quality across various driving conditions.
The timing of this refresh places the GLE and GLS in a competitive landscape where luxury SUV buyers increasingly prioritize smooth, efficient powertrains alongside traditional luxury amenities. Mercedes' focus on powertrain refinement addresses a key demand point in this segment.
Both SUVs maintain their positioning as premium alternatives to competitors like BMW's X5 and X7, as well as Audi's Q7 and SQ7 models. The 2027 refresh appears designed to strengthen that competitive stance through mechanical and operational improvements rather than dramatic design overhauls.
Car and Driver's testing validates that these updates deliver tangible improvements in driving dynamics, though the publication's brief description leaves specifics about engine options, displacement figures, or performance metrics unclear. The focus remains on the quality of the driving experience rather than raw performance numbers.
