Mercedes‑Benz GLS, the Audi Q7 and the BMW X6 side by side, you’re essentially looking at three very capable luxury SUVs but they’re aimed at somewhat different needs and tastes. I’ll walk you through how each stands out (and where they compromise) so you can see which might be the better fit for you.
The Mercedes-Benz GLS is the largest and most luxurious of the trio, especially if you value space, third-row seating and premium comfort. It offers true three-row seating for up to seven passengers (or six depending on configuration) which makes it very family-friendly. It comes with generous power: for example the base version uses a 3.0-litre inline-6 turbo with mild hybrid drive delivering around 375 hp, and there’s also a 4.0-litre V8 biturbo option pushing around 510 hp in higher trims. The ride is refined, the materials are top-tier, and the overall presence is grand. So if your priority is space + luxury a big brand feeling, the GLS makes a strong case.
On the flip side, because it’s large and built around comfort and space, you’ll see some trade-offs. The handling won’t feel as nimble as smaller SUVs, its size might make parking or tight urban driving more of a chore, and though it’s strong performance-wise, that extra size adds bulk. Also, if you don’t often use the third row, part of the GLS’s strength might be wasted for your purposes.
The Audi Q7 is a great middle ground. It also offers three rows (so it still covers the “big family SUV” scenario), but it tends to be slightly more compact and agile than the GLS. For example, the 2025 Q7 offers engine options ranging from a 261 hp turbo four-cylinder up to a 335 hp turbo V6 depending on the trim. It’s well built, has strong tech and refinement, and tends to offer better manoeuvrability in everyday use compared to the biggest SUVs. If you want luxury, performance and practicality without going full “max-size”, the Q7 hits a sweet spot.
However, the Q7 will not quite match the GLS in terms of sheer pres
