2025 BMW X7 vs. Mercedes-Benz GLS: Which Luxury SUV Reigns Supreme?

Luxury SUVs are no longer just about opulence — they now embody cutting-edge tech, versatile performance, and enough seating to rival a minivan. At the top of the segment sit two iconic nameplates: the 2025 BMW X7 and the 2025 Mercedes-Benz GLS. These full-size luxury SUVs are powerhouses in comfort, capability, and prestige. But which one truly reigns supreme?

In this comprehensive 2025 BMW X7 vs Mercedes GLS comparison, we’ll break down everything from performance to pricing, tech features to cargo space, and even dive into owner reviews and cost of ownership. Whether you're an enthusiast, a family buyer, or a luxury shopper researching your next upgrade, this guide covers everything you need to make an informed decision.

Performance & Driving Experience

BMW X7 vs GLS performance is one of the first considerations for drivers who care about power and precision. The 2025 BMW X7 comes in three primary trims:

• xDrive40i: 375-hp turbocharged inline-6
• M60i: 523-hp twin-turbo V8
• ALPINA XB7: 631-hp twin-turbo V8 (with track-level refinement)

Mercedes counters with:

• GLS 450: 375-hp turbo inline-6
• GLS 580: 510-hp twin-turbo V8
• Mercedes-AMG GLS 63: 603-hp handcrafted V8 with AMG-tuned suspension

The BMW X7 vs GLS horsepower matchup is neck and neck, but the ALPINA XB7 edges out the AMG GLS 63 slightly in raw output. BMW’s engines are often praised for sharper throttle response and more connected driving dynamics, especially in 2025 X7 vs GLS driving experience comparisons. That said, the Mercedes delivers a plush, serene ride even at highway speeds.

Want to tow a trailer or a boat? The X7 towing capacity vs GLS shows a close race: the X7 tows up to 7,500 lbs, while the GLS matches that with a max towing capacity of 7,700 lbs depending on configuration.

Verdict: BMW leans toward performance and handling. Mercedes champions effortless cruising.

Interior, Space & Comfort

Luxury isn’t just about performance — it’s about the experience behind the wheel and in every seat. The BMW X7 vs GLS interior comparison is where things really start to diverge.

The 2025 BMW X7 gets an updated cockpit with a 14.9-inch curved touchscreen running BMW’s latest iDrive 8.5 system. It pairs with a 12.3-inch digital gauge cluster, minimalist controls, ambient lighting, and an optional glass gear selector. Materials are upscale, with optional Merino leather and open-pore wood accents.

In contrast, the Mercedes GLS interior feels more traditional, with dual 12.3-inch screens running MBUX, wood trim, and bold design choices like turbine-style air vents. The GLS third row seating is more spacious than the X7’s and offers slightly easier ingress.

If you're shopping with passengers in mind, the BMW X7 vs GLS legroom favors Mercedes in the third row, but BMW offers better second-row shoulder room. Cargo space is also nearly identical, though X7 vs GLS boot space varies slightly by seat configuration.

Verdict: Mercedes wins on third-row usability and infotainment flair. BMW leads in design polish and tactile finish.

Technology & Features

The BMW X7 vs GLS tech features debate centers around two heavyweights: BMW’s iDrive vs Mercedes-Benz’s MBUX. Both systems offer:

• Apple CarPlay and Android Auto (wireless)
• Wireless charging
• Augmented reality navigation (on higher trims)
• Advanced voice control (“Hey BMW” vs “Hey Mercedes”)

However, BMW iDrive vs Mercedes MBUX comparisons often give the edge to BMW for intuitiveness, while Mercedes wins points for wow factor and deeper customization.

2025 X7 vs GLS safety features are also extensive. Both models include:

• Adaptive cruise control
• Lane keep assist
• Blind-spot monitoring
• Forward collision warning
• Semi-autonomous highway driving

X7 vs GLS sound system options include the Bowers & Wilkins Diamond surround system (X7) or the Burmester 3D audio system (GLS) — both elite, but Burmester wins by a narrow margin in clarity and volume.

Verdict: BMW offers cleaner interfaces. Mercedes serves more immersive tech.

Price, Reliability & Cost of Ownership

The 2025 BMW X7 vs GLS price range starts in the mid $80,000s and easily climbs into six figures.

• 2025 BMW X7 xDrive40i: Starting around $82,000
• X7 M60i: From $110,000
• ALPINA XB7: Around $150,000
• 2025 Mercedes GLS 450: From $88,000
• GLS 580: Starts around $111,000
• AMG GLS 63: Over $145,000

When looking at X7 vs GLS cost of ownership, both are pricey to maintain, but BMW may require more frequent servicing for high-performance trims. That said, the BMW X7 vs GLS reliability metrics are relatively even in recent JD Power and Consumer Reports rankings.
