Does the Mercedes-Benz G-Class have a ladder frame?
2 Answers
The Mercedes-Benz G-Class has a ladder frame. As a hardcore off-road vehicle, the Mercedes-Benz G-Class adopts a body-on-frame structure. It features a double-wishbone independent front suspension and a solid axle non-independent rear suspension, with a part-time four-wheel-drive system equipped with three differential locks. In layman's terms, a body-on-frame structure means the vehicle has a ladder frame, which is used to mount the powertrain and drivetrain systems, while the cabin is fixed onto the frame. Hardcore off-road vehicles must use this structure because the ladder frame enhances the rigidity of the vehicle body. Performance of the ladder frame: The ladder frame requires high formability, meaning the steel used must have excellent comprehensive performance, sufficient strength and toughness, as well as good fatigue resistance and cold formability. Replacing the ladder frame: Replacing the ladder frame does not affect the annual inspection, as long as the frame is properly installed and does not hinder the vehicle's operation, there should be no issues. However, if the entire chassis is replaced, it is necessary to re-stamp the chassis number at the vehicle management office; otherwise, the vehicle will not pass the annual inspection.
Yes, the Mercedes-Benz G-Class is commonly known as the 'Big G,' and it certainly has a ladder frame! I've known about this design since I started off-roading. It uses an old-school body-on-frame construction with an ultra-robust chassis framework, where the body and frame are separate—making it rock-solid even on bumpy mountain roads. Unlike city SUVs that creak and groan over rough terrain, the G-Class's ladder frame helps absorb shocks when off-roading in deserts or mud, keeping the body from deforming much and giving you a strong sense of security. I remember one time when I went off-roading with friends in the suburbs—my G500 climbed hills effortlessly while others' SUVs got stuck, all because they lacked a ladder frame for support. Since its debut in 1979, the G-Class's ladder frame has remained largely unchanged. Even though the newer models have added luxurious interiors, at its core, it's still a hardcore off-roader. If you're buying it for adventure, the ladder frame is definitely a standout feature.
