Launched in 2018, the W463A generation (often marketed under the W463 designation for historical reasons) marks the greatest evolution of the Classe G since its creation in 1979. While retaining its iconic cubic design, ladder frame, and three differential locks, it finally adopts an independent front suspension (double wishbone), rack-and-pinion steering, and a significantly widened and modernized cabin (integration of the dual screen, then the MBUX system). Road handling takes a giant leap, going from a rustic off-roader to a high-performance luxury SUV, although its brick-like aerodynamics still limit efficiency. In 2024, a facelift introduces mild-hybrid (MHEV) engines and a 100% electric version (G 580).
The Mercedes Classe G W463A is an automotive paradox: irrational, overpriced to buy and to run, but endowed with unparalleled charisma. In terms of reliability, this generation has corrected the dynamic wanderings of the past while retaining engines (notably the M176/M177 V8s and the OM656 diesel L6) that are particularly robust if maintained without sparing any expense. Buying a G 63 AMG or a G 500 is a highly recommendable passionate choice for those who can afford it, provided they scrupulously check the history, the condition of the windshield, and the application of the transfer case recall. The diesel (G 400 d) remains the most pragmatic choice for high mileage drivers.
