About the Mercedes-Benz GLS X166
The X166 Mercedes-Benz GLS arrived in 2015 as a significant facelift and rebranding of the second-generation GL-Class, aligning the flagship SUV with the S-Class nomenclature. As the 350 d variant, it serves as the range's workhorse, powered by the proven OM642 V6 diesel engine paired with a smooth 9G-TRONIC transmission. It remains one of the few luxury SUVs of its era to offer genuine adult-sized seating across all three rows, combined with a 2,300-litre maximum cargo capacity. Standard AIRMATIC air suspension provides a composed, wafting ride, though its sheer physical footprint and 2.4-tonne kerb weight are always apparent on tighter roads.
