Audi Q9 vs BMW X7 vs Mercedes-Benz GLS: Full-Size Luxury SUV Comparison

The full-size, three-row luxury SUV class has long belonged to the BMW X7 and Mercedes-Benz GLS. Now the all-new Audi Q9 — Audi’s first full-size SUV — enters the conversation. Here is how the Q9 stacks up for shoppers near Sacramento.

The full-size three-row class

All three deliver genuine three-row seating for up to seven, commanding presence and flagship luxury. The Q9 arrives as the newest of the group, built from the ground up for the U.S. market and positioned directly against the established X7 and GLS.

Space & third row

At roughly 209 inches long, the Q9 offers full-size proportions with up to 87.7 cubic feet of cargo space and an available six-seat layout with power-adjustable second-row captain’s chairs. Like its rivals, it is engineered so the third row is usable, not an afterthought.

Technology & interior

The Q9 brings Audi’s newest cabin technology: an 11.9-inch virtual cockpit plus, a 14.5-inch MMI touch display and an available 12.3-inch front-passenger screen, an Audi assistant with ChatGPT integration, available Digital Matrix LED headlights and the world’s first curved digital OLED taillights. The largest panoramic sunroof ever fitted to an Audi and an available 22-speaker Bang & Olufsen 4D system round out a genuinely flagship interior.

Performance & capability

Every Q9 pairs a 429-hp twin-turbo V6 with standard quattro all-wheel drive and standard adaptive air suspension, and the SQ9 adds a 591-hp V8 with all-wheel steering. It tows up to 7,700 pounds when properly equipped. Standard quattro and standard air suspension are differentiators against rivals that often reserve all-wheel drive or air springs for higher trims or options.

Beyond the vehicle, buyers value a dealer they can rely on. Audi Elk Grove near Sacramento offers expert guidance, transparent pricing and dedicated Audi service — and can help you reserve one of the first Q9s to reach Northern California.
