History of the Mercedes-Benz GL-Class

Unveiled in 2006, the Mercedes-Benz GL-Class marked the brand’s commitment to full-size luxury SUVs, targeting drivers needing substantial space paired with prestige. Positioned above the GLE, the GL-Class embraced the American market’s appetite for large, comfortable vehicles. Each generation delivered a three-row, seven-seat setup, affirming its place as the flagship SUV in Mercedes’ portfolio – distinct from the off-road-oriented G-Class. Over the years, the GL-Class evolved with advances in technology, comfort, and efficiency, remaining a benchmark for luxury SUVs with family utility and refined drive characteristics.

Model History of the GL-Class

The first generation of the GL-Class began with the X164 series (from 2006) and received significant updates leading to the X166 (from July 2012 to December 2015). The X166 era brought a more sculpted exterior, advanced safety tech, and engine upgrades, such as the 5.5-litre biturbo V8 and AMG variants. Eventually, the GL-Class was rebranded as the GLS, continuing the tradition of luxury, spaciousness, and innovation. Each GL-Class generation is linked to continuous technological progress and adaptation to both US and European demands, with distinctive changes in design language, comfort systems, and drive assistance features.

With its standard 7-seater configuration, the GL-Class excels in practical luxury. Key aspects include the 7-speed automatic transmission, powerful torque up to 700 Nm, high towing capacity (up to 3,500 kg), and a spacious interior with amenities like climate control, panoramic sunroof, and Harman Kardon sound. Performance-focused options such as the original AMG version and biturbo V8 enhance its appeal. Additional technological options—360° camera, advanced infotainment systems—cement its status as a leader among full-size SUVs.

Uniquely Mercedes details are visible in materials and layout, while additional kit options might include Android-based navigation/media, 360° cameras, and automatic climate control.
