2019 Mercedes-Benz GLS-Class

Pros: Excellent build quality; broad range of engine choices; quiet cabin

Cons: Second and 3rd-row seats aren’t as spacious as many premium-large SUVs; steep price premium of AMG GLS 63 model

CG Says: The 2019 Mercedes-Benz GLS-Class is essentially unchanged. In 2017, Mercedes changed the name of its largest crossover SUV from GL to GLS to better sync up with the naming structure of its passenger cars. Three engines are offered. GLS 450 is powered by a 362-horsepower turbocharged 3.0-liter V6. The GLS 550 has a turbocharged 4.7-liter V8 with 449 hp and the high-performance AMG GLS 63 has a 577-hp turbocharged 5.5-liter V8. GLS 450 and GLS 550 have a 9-speed automatic transmission, while AMG GLS 63 has a 7-speed automatic. All-wheel drive is standard. Available safety features include autonomous emergency braking, driver-attention monitor, adaptive cruise control, adaptive headlight high beams, lane-keep assist, and blind-spot alert. Other available features include park assist, surround-view camera, panoramic sunroof, and power-folding third-row seats. The 7-passenger GLS-Class doesn’t have the sheer interior volume of some premium large SUVs, but its accommodations are more than adequate for the majority of buyers. Relatively trim exterior dimensions ease parking and maneuverability, too. Any GLS offers impressive power and high levels of refinement. Note that prices climb quickly as you add options, particularly the Designo interior packages and Bang & Olufsen audio system. The AMG GLS 63 model is for high rollers only.
