Handcrafted Heart of the 2026 AMG\u00ae GLS 63 SUV Powertrain <\/h3>\n\n\n\n

At the core of this vehicle lies the handcrafted 4.0L Mercedes V8 biturbo engine. This “one man, one engine<\/a>” 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. <\/p>\n\n\n\n

Athletic Engineering and AMG\u00ae Performance <\/h3>\n\n\n\n

The 2026 AMG\u00ae GLS 63 SUV powertrain works in concert with the AMG SPEEDSHIFT\u00ae 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. <\/p>\n\n\n\n
