2010 Mercedes-Benz GL-Class: What's New, Specs & Features
Last updated August 4, 2026
The 2010 Mercedes-Benz GL-Class gets a light refresh rather than a full redesign. The headline change is the GL320 BlueTEC’s rename to GL350 BlueTEC, accompanied by a small increase in diesel torque.
About the 2010 Mercedes-Benz GL-Class
1st generation (X164, 2007-2012), fourth model year, light refresh year before the all-new 2013 redesign.
Mercedes positioned the GL-Class as a full-size 7-passenger luxury SUV that blended family space, strong safety engineering, towing ability, and smoother road manners than many truck-based rivals. Its big advantage in this class was usability: a genuinely roomy third row, standard all-wheel drive and air suspension, and a choice between a long-range clean-diesel V6 or strong V8 power. In plain terms, it was the big Mercedes SUV for families who needed size and capability without giving up comfort.
The GL350 BlueTEC is the long-range, road-trip-focused diesel, while the GL450 provides V8 power in the middle of the range. The GL550 is the quicker, more richly equipped version, with a stronger V8, navigation, a rearview camera, premium audio, and heated and ventilated front seats. Every model has all-wheel drive, self-leveling air suspension, and three-row seating.
