The G 550’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the GX’s standard 60 series tires. The G-Class’ optional tires have a lower 40 series profile than the GX’s optional 55 series tires.

The G-Class’ power parking brake sets with one touch and releases with one touch or automatically. The GX’s parking brake has to be released manually.

The G-Class’ rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GX’s standard manually variable intermittent wipers have to be constantly adjusted.
