Full-size SUVs continue to represent the peak of comfort and innovation, offering three rows of space and premium features throughout. For 2025, the BMW X7 and Mercedes-Benz GLS-Class stand out as two of the most refined vehicles in the segment. Both are engineered for families, professionals, and those who want a commanding presence on the road.
While they share some similarities in space and technology, the real differences appear in how each brand approaches design, performance, and the driving experience. This comparison will help you weigh each model to decide which one better fits your lifestyle.
BMW introduces the 2025 X7 with refreshed exterior styling that includes a bold front grille and updated lighting. Its wide stance and clean profile give it a confident appearance. Step inside and you’ll find a well-balanced mix of digital innovation and premium materials, including a curved display and available glass controls that feel high-end yet practical.
Mercedes-Benz brings a more traditional presence with the GLS-Class. Rounded body lines and chrome accents add to its upscale look. Inside, wood trim, ambient lighting, and optional second-row captain’s chairs create an atmosphere focused on comfort. Compared side by side, the X7 presents a sportier, more modern design, while the GLS stays close to classic luxury roots.
BMW equips the X7 with the iDrive 8.5 system, offering a 14.9-inch touchscreen and customizable features. The digital cockpit blends functionality with sharp graphics. Wireless smartphone connectivity comes standard, along with a voice assistant and available surround sound system. Safety is supported by features like lane keeping assistance, frontal collision warning, and adaptive cruise control.
Mercedes-Benz fits the GLS with its MBUX system, split between two 12.3-inch displays. The interface is clear and easy to use, with voice control and similar smartphone compatibility. Safety features include Active Brake Assist, Blind Spot Assist, and multiple pre-collision systems. BMW’s tech package feels more intuitive and up-to-date, especially for drivers who prefer a streamlined interface.
BMW offers three versions of the X7: the xDrive40i with 375 horsepower, the M60i with 523 horsepower, and the ALPINA XB7 pushing up to 631 horsepower. Each comes with all-wheel drive and adaptive suspension, providing a smooth ride and responsive handling. Acceleration is brisk, even on the base model, with the ALPINA delivering sports-car levels of power.
Mercedes gives the GLS 450 a mild-hybrid six-cylinder engine rated at 375 horsepower. The GLS 580 moves up to a V8 producing 510 horsepower, while AMG and Maybach variants push performance even further. All versions include 4MATIC all-wheel drive and air suspension. While the GLS delivers solid performance across trims, the X7 lineup offers sharper responsiveness and higher peak output, especially for drivers looking for excitement behind the wheel.
Each model has strengths depending on what matters most to you. The GLS-Class emphasizes rear-seat comfort, especially in the Maybach variant, and leans into a smooth, composed ride ideal for long trips. Its styling, inside and out, reflects a classic interpretation of luxury.
BMW’s X7 offers a more modern take. It balances comfort with precision, bringing powerful engine options and a tech-focused interior. From driving enjoyment to interior layout, this SUV caters to those who want both elegance and an edge. Whether you’re drawn to advanced features or confident road manners, the X7 delivers across the board.
