Mercedes-Benz GLS vs Audi Q6 e-tron

It could be said that the Mercedes GLS is the S-Class of SUVs, but that’s not entirely accurate. The S-Class sedan commands a significant premium over the GLS, while the legendary G-Class SUV is even more expensive than the S-Class. Nevertheless, for buyers who want a three-row SUV with a three-pointed star on its grille, the 2026 Mercedes-Benz GLS is the right choice because it offers more passenger room and cargo space than any other model in the automaker’s lineup.

Verdict: Large, luxury SUVs are a lot more expensive than they used to be, and while the 2026 Mercedes GLS can’t match them for sheer size and capability, its manageable dimensions, undeniable comfort, refinement, and rewarding driving dynamics make a strong case.

The 2025 Audi Q6 e-tron is a new addition to the German luxury brand’s electric vehicle and SUV lineups. It’s a two-row, five-seat midsize model that slots between the Q4 e-tron and Audi Q8 e-tron SUVs, giving Audi a more direct rival to the Acura ZDX, Cadillac Lyriq, and Mercedes-Benz EQE SUV—although it also dabbles in Tesla Model Y and Porsche Macan EV territory.

Verdict: Compared to its rivals, the Q6 e-tron is a better choice for buyers who want an EV that still feels like a normal SUV.
