Overview
The 2026 Mercedes-AMG GLS 63 sits at the top of the GLS lineup as the performance-focused flagship, pairing full-size three-row luxury with handcrafted AMG V8 power. It uses a 4.0-liter biturbo V8 with 48-volt mild hybrid assist, delivering 603 hp and 627 lb-ft of torque. A 9-speed AMG SpeedShift TCT transmission and AMG Performance 4Matic+ all-wheel drive send power to all four wheels, pushing the nearly three-ton SUV from 0 to 60 mph in 4.1 seconds.
AMG Ride Control+ air suspension with Active Roll Stabilization comes standard. This setup suits buyers who want maximum passenger space and luxury without giving up real performance.

Pros and Cons
Pros:
- 603-hp handcrafted biturbo V8 delivers strong acceleration in a 7-seat SUV
- Three-row layout includes adult-friendly third-row legroom at 34.6 inches
- AMG Ride Control+ air suspension with Active Roll Stabilization limits body roll
- Up to 84.7 cu-ft of cargo space matches full-size body-on-frame SUVs
- Manufaktur Arctic Silver Edition adds exclusivity for 2026
Cons:
- $151,050 starting price rises quickly with options and Manufaktur packages
- 17 mpg combined fuel economy increases running costs
- 4.1-second 0–60 performance comes with a curb weight near 6,000 lbs
- Adaptive cruise control comes standard, but some driver aids require packages
- Third-row access remains tight despite good legroom once seated
Verdict
The Mercedes-AMG GLS 63 full-size SUV blends multiple roles into one vehicle. It serves as a 7-seat SUV, a luxury cruiser, and a performance machine capable of reaching 60 mph faster than many sports cars. The handcrafted 4.0-liter biturbo V8 produces 603 hp and 627 lb-ft, delivering strong acceleration and a distinctive exhaust note. The 48-volt system smooths low-speed response and supports cylinder deactivation, though 17 mpg combined still places it on the higher end of fuel consumption.
On the road, the AMG Ride Control+ suspension balances comfort and control. In Comfort mode, it handles rough surfaces with composure expected in a high-end SUV. Switching to Sport or Sport+ sharpens responses, increases steering weight, and improves cornering stability. Active Roll Stabilization helps keep body movement in check, though its size and weight remain noticeable.
The Manufaktur Arctic Silver Edition adds visual distinction for 2026, but the core appeal stays the same. The GLS 63 AMG combines three rows of usable seating, up to 84.7 cu-ft of cargo space, 7,700 lbs of towing capacity, and rapid acceleration. The BMW X7 M60i offers similar pace at a lower price but lacks the AMG V8 character. The Cadillac Escalade V delivers more power but trades some refinement. Within this segment, the Mercedes-AMG GLS 63 stands out by covering performance, space, and luxury in a single package.
