Exterior

The 2026 Mercedes-Benz GLS commands the road with refreshed styling that emphasizes its flagship status. A revised front grille with vertical chrome accents and slimmer, more aggressive LED headlights give the GLS a more focused look for 2026. Standard 21-inch alloy wheels provide a stable, muscular stance, while the AMG body styling (standard on higher trims) adds a sporty flair to its elegant silhouette. Functional luxuries like the panoramic sunroof, power-folding side mirrors with logo projectors, and hands-free power liftgate ensure that the GLS is as practical as it is beautiful.

Performance

The GLS is engineered to glide over Illinois road imperfections while maintaining complete composure. For 2026, the refined AIRMATIC suspension and intelligent AWD make it the perfect all-weather companion. Performance highlights include:

• Mild-Hybrid Efficiency: The Integrated Starter-Generator (ISG) provides a seamless boost of 20 hp and 148 lb-ft of torque for smoother launches and better efficiency.

• "Transparent Hood" View: An innovative off-road feature that uses cameras to show a virtual view of the ground under the front engine—perfect for navigating tricky drives.
• Exceptional Towing: When properly equipped, the GLS can tow up to 7,700 pounds, making it ideal for hauling boats to the Illinois River or trailers for long hauls.
