Why it stands out
The 2017 Mercedes-Benz GLS is designed to offer an unparalleled blend of comfort, style, and performance in a midsize SUV format. Notably, it features luxurious materials, an intuitive technology setup, and ample space, accommodating up to seven passengers with ease. While it may not boast the largest cargo capacity compared to competitors like the Cadillac Escalade or Lincoln Navigator, the GLS impresses with its powerful engine options, including a robust 3.0-liter twin-turbo V6 delivering 362 horsepower. Its three rows of seating adjust comfortably, reflecting Mercedes-Benz's aim to create a family-friendly vehicle without sacrificing the luxurious feel synonymous with the brand. Owners particularly appreciate the GLS for its smooth handling and high-quality ride, though some report minor drawbacks like limited third-row accessibility and missing cutting-edge tech features available in newer models.
