2027 Mercedes-Benz GLS Release Date for USA – The 2027 Mercedes-Benz GLS-Class, often called the “S-Class of SUVs,” has received a substantial mid-cycle refresh. For U.S. buyers, this full-size three-row luxury SUV brings updated styling, more powerful engines, advanced AI-driven technology, and refined comfort features while remaining produced at Mercedes-Benz’s Tuscaloosa, Alabama plant.
2027 Mercedes-Benz GLS-Class Release Date
Mercedes-Benz revealed the refreshed 2027 GLS in late March 2026. U.S. sales and dealer arrivals are expected in the second half of 2026, specifically late 2026 or fall 2026. Multiple sources, including Edmunds, Cars.com, Kelley Blue Book, and U.S. News, point to this timeline, with some projecting availability by mid-fall or around Thanksgiving.
Higher-performance AMG GLS 63 models are also targeted for fall 2026 arrival, while the ultra-luxury Mercedes-Maybach GLS 680 is expected later in 2026. Exact timing can vary by trim, options, and regional allocation, so prospective buyers should contact local Mercedes-Benz dealers for the latest inventory and order status.
What’s New in the 2027 GLS?
This is not an all-new generation but a significant update to the model that debuted in 2019 (with a milder refresh in 2024). Key improvements focus on power, technology, ride quality, and flagship presence to keep the GLS competitive against rivals like the Cadillac Escalade, BMW X7, and Range Rover.
Design and Exterior Updates
The exterior receives a more assertive front end with a larger grille featuring chrome detailing and available contour lighting. Headlights incorporate Digital Light technology and a three-pointed star motif, while the taillights feature a full-width design with starry elements. An optional illuminated standing Mercedes-Benz star hood ornament is available for the first time on a GLS SUV. New paint colors (such as Dark Petrol and MANUFAKTUR Patagonia Red Metallic) and wheel designs (including 21- and 22-inch options) further distinguish the 2027 model. A panoramic roof is standard.
Interior and Technology Features
Inside, the biggest change is the standard MBUX Superscreen: three 12.3-inch displays spanning the dashboard under a single seamless glass surface, including a dedicated front passenger screen. The system runs on Mercedes’ new MB.OS “supercomputer” architecture with AI capabilities, supporting over-the-air updates and advanced voice control.
Additional comfort upgrades include an available Executive Rear Seat Package with multi-contour massaging seats, optional rear-seat entertainment screens, improved sound insulation, and enhanced ambient lighting. The AIRMATIC air suspension now features cloud-based damper regulation that anticipates road conditions using crowdsourced data, with the optional E-ACTIVE BODY CONTROL system available on higher trims for even greater ride refinement.
Powertrain Options and Performance
U.S. models are expected to offer:
- GLS 450 4MATIC: Turbocharged 3.0-liter inline-six producing 375 horsepower and 413 lb-ft of torque (torque increased for better responsiveness), paired with a 48-volt mild-hybrid system and 9-speed automatic.
- GLS 580 4MATIC: Twin-turbocharged 4.0-liter V8 with a new flat-plane crankshaft design, delivering 530 horsepower and 553 lb-ft of torque (up from previous figures).
Both feature standard 4MATIC all-wheel drive. The high-performance Mercedes-AMG GLS 63 steps up to 603 horsepower and 627 lb-ft, with claimed 0-60 mph times under 4 seconds. The Maybach GLS 680 uses a similar high-output V8 configuration focused on ultra-luxury. These updates aim to improve responsiveness while meeting future emissions standards.
Pricing Expectations for US Buyers
Official U.S. pricing has not been fully announced as of mid-2026, but estimates place the starting price around $95,000. This is modestly higher than the previous generation’s base (near $90,000–$91,600 including destination). Fully loaded or AMG/Maybach versions will command significantly higher prices, with the Maybach expected well above $150,000–$200,000. Final figures and complete option pricing should arrive closer to on-sale timing.
Competitors and Buying Advice for USA Shoppers
The 2027 GLS continues to target family-oriented luxury buyers seeking three-row space, refined highway manners, and status. It competes directly with the Cadillac Escalade, BMW X7, Lincoln Navigator, Lexus LX, and Land Rover Range Rover. Its strengths remain exceptional ride quality, advanced technology, and strong residual values in the U.S. market.
If you are considering the 2027 model, monitor dealer inventories starting in fall 2026, compare configurations early (especially for preferred colors and packages), and factor in potential wait times for higher trims or Maybach variants. Contacting a local Mercedes-Benz dealer remains the best way to confirm exact availability and arrange a preview or order.
