Every iteration of the 2017 GLS-Class comes standard with all-wheel drive and a multimode terrain selector positioned on the center console. This ensures confident handling and traction, regardless of weather conditions or road surfaces.
Inside the cabin, the 2017 Mercedes-Benz GLS Class envelops occupants in premium comfort and sophisticated technology. MB-Tex premium vinyl upholstery, heated front seats, and a 10-way power driver’s seat with four-way power lumbar support offer a foundation of comfort. Driver-seat memory settings, a power-adjustable leather-wrapped steering wheel, and an auto-dimming rearview mirror further refine the driving experience.

It distinguishes itself with a more powerful V8 engine, larger 21-inch alloy wheels, adaptive suspension dampers, and sporty exterior styling cues. Soft-close doors and upgraded interior trim, including wood steering-wheel inserts, further enhance the luxury quotient.

Notably, on the GLS 450, this package also adds the GLS 550’s standard adaptive dampers.
At the apex of the 2017 Mercedes-Benz GLS Class range sits the high-performance AMG GLS 63. This model elevates the driving experience to exhilarating levels with an even more potent V8 engine, a sport exhaust system, and exclusive 21-inch alloy wheels.
