What Powers the 2025 AMG® GLS 63 SUV? 

Under the hood of this SUV is a handcrafted AMG 4-liter V8 biturbo engine, enhanced with a hybrid Integrated Starter-Generator. This combo delivers 603 horsepower and 627 lb.-ft. of torque, allowing it to sprint from 0 to 60 mph in just 4.1 seconds. Whether merging onto the freeway or overtaking with confidence, the power is there—instant and fierce. The “hot inside V” turbo layout reduces turbo lag, while AMG Cylinder Management can deactivate cylinders when full power isn’t needed to improve fuel efficiency.  

The AMG SPEEDSHIFT TCT 9G transmission offers snappy shifts in Sport and Sport+ modes or laid-back cruising in Comfort mode. Behind the wheel, AMG DYNAMIC SELECT provides multiple drive modes—including Race, Trail, and Sand—so the SUV adapts quickly to road surfaces and driving moods.

Can the 2025 AMG® GLS 63 SUV Handle Off-Roading and Towing? 

Absolutely. With AMG Performance 4MATIC+ all-wheel drive, torque can be sent up to 100% to the rear wheels for more dynamic handling. For off-road adventures, drivers can activate the “Transparent Hood” view and Off-Road Menu, offering a digital peek at terrain and angles below. The Downhill Speed Regulation (DSR) feature lets the SUV crawl safely on steep inclines without the driver touching the pedals.  

Towing is another area where the AMG® GLS 63 stands strong. The Class IV trailer hitch allows for towing up to 7,700 lbs., making it capable of pulling a camper, jet skis, or even a car hauler. Built-in Trailer Stability Assist keeps things under control when the load shifts or crosswinds hit. 

In corners, the AMG electronic limited-slip rear differential and AMG ACTIVE RIDE CONTROL keep body roll in check while providing responsive grip on twisty roads. And when it’s time to stop, massive AMG high-performance brakes with red calipers clamp down hard, keeping things under control even at higher speeds.
