2025 Mercedes-Benz G 550 SUV

The G 550 represents the signature G-Class spirit—robust, timeless, and ready for anything. With a powertrain that blends combustion and hybrid systems, the G 550 brings modern efficiency and classic strength together under one roof.

Engine Specifications

Under the hood of the G 550 is a 3.0-liter inline-6 turbo engine enhanced by a hybrid assist system and an electric auxiliary compressor. This advanced setup delivers a total of 443 horsepower and 413 pound-feet of torque. The result is a smooth and forceful drive that accelerates from 0 to 60 mph in just 5.3 seconds—impressive for a full-size SUV with a traditional off-road frame.

Transmission

Matched to this refined engine is the 9G-TRONIC 9-speed automatic transmission. It provides seamless gear transitions for both city driving and rugged terrains. Whether you’re commuting through the Valley or heading up into the desert hills, the G 550 delivers confident, responsive performance.

Size and Capacity

Despite its robust build and powerful capabilities, the G 550 maintains a practical size for everyday driving. Inside, you’ll find seating for five and 34.8 cubic feet of cargo space in the rear, making it ideal for weekend getaways or luxury family adventures. The upright, boxy design maximizes interior space while standing out with unmistakable style.

2025 Mercedes-Benz G 580 with EQ Technology SUV

For those looking to embrace the future of the G-Class, the 2025 G 580 with EQ Technology delivers electric innovation without compromising the rugged appeal Mercedes-Benz is known for. This all-electric G-Class trim is engineered for power, silence, and sustainability.

Engine Specifications

The G 580 with EQ Technology swaps out traditional fuel for electric performance. It’s equipped with four permanently excited synchronous motors—one for each wheel. This setup allows the G 580 to produce a staggering 579 horsepower and 859 pound-feet of torque. With this powertrain, the G 580 can launch from 0 to 60 mph in just 4.6 seconds, offering even more rapid acceleration than its gas-powered sibling.

Transmission

Instead of a standard transmission system, the G 580 uses a 2-speed setup at each wheel motor, giving the SUV advanced torque control and terrain-handling capabilities. This system not only enables smooth power delivery but also allows for precise off-road maneuvering, giving drivers electric performance with traditional G-Class versatility.

Size and Capacity

Though it features cutting-edge electric components, the G 580 keeps the same iconic proportions as the G 550. It also maintains seating for five and offers 34.8 cubic feet of cargo space behind the rear seats. The bold silhouette, angular structure, and elevated ride height continue to reflect the unmistakable G-Class design language.
