Why it stands out

The 2021 Mercedes-Benz GLS-Class is often referred to as the S-Class of SUVs, embodying a commitment to luxury and comfort that is hard to match. With spacious seating for seven and an array of high-end materials, it's designed for those who prioritize both elegance and practicality. The GLS-Class shines with multiple powertrain options, including a robust V8 engine that delivers powerful performance when needed. Its interior is fitted with the cutting-edge MBUX infotainment system, featuring a massive touchscreen and advanced voice-control capabilities. Additionally, the GLS-Class boasts a suite of safety features that enhance driving confidence and security. However, it's worth noting that while the GLS offers impressive tech and luxury, the third row can be cramped for adult passengers, and fuel economy might not meet everyone’s needs. Nonetheless, its overall blend of comfort, technology, and performance makes the 2021 GLS a standout choice in the full-size luxury SUV segment.
