Redesigned Interior & Cutting-Edge Technology
The 2020 GLS-Class represents a significant leap forward in cabin design and technological integration. The most striking feature is the standard Mercedes-Benz User Experience (MBUX) system, which dominates the dashboard with its twin 12.3-inch high-resolution displays. These seamlessly integrated screens create a widescreen effect that combines the digital instrument cluster and infotainment system into one cohesive unit.
Interior Space & Comfort
Mercedes has addressed one of the most important factors for three-row SUV buyers - passenger space. The redesigned GLS offers:
- 3.4 inches more second-row legroom when seats are fully extended
- Available captain's chairs for six-passenger luxury configuration
- Enhanced third-row access with wider door openings
- Premium materials including optional Nappa leather and open-pore wood trim

Performance & Powertrain Options
The 2020 GLS-Class introduces two new engine options, both paired with a nine-speed automatic transmission and standard 4MATIC all-wheel drive:
| Model | Engine | Horsepower | Torque (lb-ft) |
|---|---|---|---|
| GLS450 | Turbocharged 3.0L inline-6 | 362 hp | 369 |
| GLS580 | Twin-turbo 4.0L V-8 | 483 hp | 516 |
Both engines feature Mercedes' EQ Boost mild hybrid system, which provides short electric assist and helps with fuel efficiency. The GLS580's powerful V-8 delivers acceleration that rivals many sports cars while maintaining the refinement expected from a Mercedes-Benz flagship SUV.

The 2020 GLS450 starts at $76,195 (including destination), representing a $5,050 increase over the outgoing model. This positions it slightly above the BMW X7 xDrive40i's $74,895 starting price, but with more standard features and technology.

Why the 2020 GLS-Class Stands Out
The redesigned GLS-Class represents Mercedes-Benz's most complete three-row SUV offering to date. Several factors make it particularly compelling:
1. Technological Leadership
The MBUX system sets a new standard for intuitive operation in luxury vehicles, with natural language voice control, augmented reality navigation, and deep personalization options.
2. Superior Interior Flexibility
The available six-passenger configuration with second-row captain's chairs provides limousine-like comfort, while the seven-passenger layout offers maximum versatility.
3. Enhanced Driving Dynamics
Despite its size, the new GLS features improved handling thanks to standard AIRMATIC air suspension and optional E-ACTIVE BODY CONTROL that can individually adjust each wheel's suspension.

Final Thoughts
The 2020 Mercedes-Benz GLS-Class successfully elevates the luxury three-row SUV experience with its combination of spacious interior, cutting-edge technology, and refined powertrains. While the price increase over the previous generation may give some buyers pause, the additional content and improvements justify the premium. For those considering the BMW X7, the GLS offers a compelling alternative with Mercedes' signature luxury and the latest in automotive technology.
As the flagship of Mercedes' SUV lineup, the GLS-Class continues to set the standard for what a premium three-row vehicle should be, blending passenger comfort, technological innovation, and driving dynamics in a package that's difficult to match.
