Dominating the Desert in Style in the 2026 AMG® GLS 63 SUV

2026 AMG® GLS 63 SUV Powertrain and Performance

Finding a vehicle that balances family utility with track-ready soul is a rare feat, yet the latest flagship from Affalterbach achieves exactly that. At Mercedes-Benz of Scottsdale, located in the heart of Scottsdale, AZ, we are proud to showcase the 2026 AMG® GLS 63 SUV powertrain. This engineering marvel caters to those who refuse to compromise, offering the space of a three-row luxury cruiser alongside the heart of a supercar. Whether you are navigating the scenic curves of the McDowell Mountains or cruising down Camelback Road, this vehicle commands respect through its sheer presence and mechanical sophistication. 

Handcrafted Heart of the 2026 AMG® GLS 63 SUV Powertrain 

At the core of this vehicle lies the handcrafted 4.0L Mercedes V8 biturbo engine. This “one man, one engine” masterpiece produces a staggering 603 horsepower and 627 lb-ft of torque. Furthermore, the engine utilizes a “hot inside V” turbocharger configuration, which places the turbos between the cylinder banks. This design allows for shorter air paths and immediate throttle response. To maximize efficiency and low-end grunt, the powertrain features an Integrated Starter-Generator. This 48-volt mild-hybrid system provides an additional boost of electric torque while ensuring that the stop-start transitions remain nearly imperceptible. 

Athletic Engineering and AMG® Performance 

The 2026 AMG® GLS 63 SUV powertrain works in concert with the AMG SPEEDSHIFT® TCT 9-speed automatic transmission. Consequently, shifts are rapid and precise, whether you are using the manual paddle shifters or letting the computer optimize your journey. Additionally, the AMG Performance 4MATIC+ all-wheel drive system features a fully variable torque distribution. This means the SUV can transition from the stability of all-wheel drive to the agility of a rear-biased setup in an instant. 

Key performance features include: 

• An adaptive AMG RIDE CONTROL+ air suspension system. 

• AMG ACTIVE RIDE CONTROL roll stabilization with 48-volt technology. 

• High-performance braking with massive six-piston front calipers. 

• The AMG Performance Exhaust System for a customizable V8 soundtrack. 

• Dynamic engine mounts that stiffen or relax based on driving intensity.
