Used 2021 Mercedes-Benz GLS GLS 450

The 2021 Mercedes-Benz GLS 450 4MATIC is a full-size luxury SUV that serves as the entry-level trim in the GLS lineup, but it still delivers a strong balance of performance, comfort, and advanced technology. It is powered by a 3.0-liter turbocharged inline-6 engine paired with a 48-volt mild-hybrid system (EQ Boost), producing about 362 horsepower and 369 lb-ft of torque. This setup is matched with a 9-speed automatic transmission and Mercedes 4MATIC all-wheel-drive system, giving it smooth acceleration and confident traction in different driving conditions. It can go from 060 mph in roughly 5.8 to 5.9 seconds, which is quick for a large SUV of its size.

In terms of driving experience, the GLS 450 is known for prioritizing comfort and refinement over sporty handling. The air suspension helps it glide over rough roads, making it feel more like a luxury cruiser than a traditional SUV. Inside, it offers three-row seating for up to seven passengers, high-quality materials, and Mercedes MBUX infotainment system with dual widescreen displays. Features like ambient lighting, advanced driver assistance systems, and available massaging seats make it feel very upscale, especially for long-distance travel. However, because of its size and weight, it can feel less agile in tight corners, and fuel economy is moderate at around 21 MPG combined.

Overall, the 2021 GLS 450 4MATIC is aimed at buyers who want a spacious, comfortable, and tech-loaded luxury SUV rather than a performance-focused one. It competes with vehicles like the BMW X7 and Cadillac Escalade, but stands out for its smooth ride quality and strong interior luxury. With a towing capacity of up to 7,700 pounds and strong highway performance, it also works well as a practical family SUV that doesn't sacrifice premium feel.
