The G-Class is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few passenger car vehicles to have such a feature. Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of 46 years. Only the Unimog surpasses it. In 2018, Mercedes-Benz introduced the second-generation W463 with heavily revised chassis, powertrain, body, and interior. In 2023, Mercedes-Benz announced plans to launch a smaller version of the G-Class, named "little G"—though no definitive date was given for the launch....(Read more on Wikipedia)
