Why it stands out

The 2023 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 2,400 litres of cargo space. It is positioned as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability, which helps explain its appeal to families who want a large, upscale SUV without moving to something more specialised. The buying guide also notes that the GLS is not the tallest, the longest, or the most expensive Mercedes, so its distinction is less about sheer size than about how it packages luxury, practicality, and versatility.

For 2023, the panoramic moonroof became standard on the GLS 450. More broadly, the second-generation GLS brought a curvier exterior, a wide-screened cabin, and a longer wheelbase, while also adding more comfort and safety features. Standard equipment was generous, including dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, wireless charging, heated front seats, power-folding third-row seats, and power-adjustable second-row seats. The model also benefited from standard 4Matic all-wheel drive, Airmatic air suspension, and a nine-speed automatic transmission, which reinforce its polished, easygoing character.

Its strengths are clear: comfort, premium interior materials, and easy-to-use technology. At the same time, the buying guide points to a few drawbacks, including touch-sensing controls, third-row seat access, and the AMG Line Package impeding entry and exit. Even so, the 2023 Mercedes-Benz GLS remains appealing because it combines genuine three-row usefulness with a distinctly upscale feel and a long list of standard features.
