2026 Mercedes-Benz GLS 450: Three-Row Luxury Built For Real Life

The 2026 Mercedes-Benz GLS 450 gives you the passenger space and flexibility people look for in a three-row SUV, along with the comfort expected from Mercedes-Benz. It has room to bring more along, whether you are driving around town or heading farther from home. At Mercedes-Benz of Chesterfield, we can help you explore an SUV made for busy days and longer trips. 

Power and Performance 

A full cabin should not leave your SUV feeling strained. The Mercedes-Benz GLS 450 uses a turbocharged 3.0-liter inline-six with mild-hybrid technology to produce 375 horsepower and 369 pound-feet of torque, providing smooth power for highway merging, passing, or traveling with passengers and luggage aboard. The 9G-TRONIC® nine-speed automatic transmission works with standard 4MATIC® all-wheel drive to keep power delivery composed. AIRMATIC® suspension adjusts damping and vehicle level as roads and cabin loads change, helping everyone stay comfortable along the way. 

Technology Features 

The technology serves the whole cabin, not only the person behind the wheel. Twin 12.3-inch displays place vehicle information, navigation, and MBUX® controls up front, with wireless Apple CarPlay® and Android Auto™ providing access to compatible smartphone apps. USB-C ports and front-row or optional second-row wireless charging help keep devices ready, while the standard 13-speaker Burmester® surround sound system with Dolby Atmos® carries detailed audio through all three rows.

Towing and Cargo Space 

When you need more room for gear, the power-adjustable second row and power-folding third row help open up as much as 84.7 cubic feet of cargo space. Towing capacity is a generous 7,700 pounds when properly equipped. 

Safety Features 

Three-row versatility often means crowded parking lots, highway traffic, and changing weather are part of the job. The standard Surround View System provides a bird's-eye view around your new Mercedes-Benz SUV, which can be helpful when backing into a space. Active Distance Assist DISTRONIC® can adjust speed with traffic, while Active Steering Assist can provide support within clearly marked lanes. PRE-SAFE® can also prepare select occupant-protection systems if a possible collision is detected. These features assist you, but attentive driving remains essential.
