Mercedes Classe G W463A (2018 – 2025)

Reliability score : 8.5/10

Mercedes-Benz Classe G (W463A) Launched in 2018, the W463A generation (sometimes unofficially called W464) represents the greatest technical evolution of the Classe G since its birth in 1979. While retaining its iconic cubic design, ladder frame, and three differential locks, it adopts an independent front suspension, rack-and-pinion steering, and an ultra-modern interior (dual screen). Positioning: Absolute luxury off-road vehicle, status-enhancing and exclusive. Facelift (2024): Slight aerodynamic tweaks, transition to the MBUX multimedia system, mild hybridization (MHEV) on all combustion engines, and introduction of the 100% electric version (G 580 EQ). Overall rating: An engineering masterpiece that achieves the impossible: marrying pure off-road capabilities with ride comfort worthy

✅ Strengths

Exceptional OM656 diesel engine: torquey, smooth, and reliable
Intact off-road capabilities (3 locks, low range)
Ride comfort and steering precision transformed compared to the previous generation
Interior finish quality worthy of an S-Class
Almost non-existent depreciation (highly sought-after vehicle on the used market)

⚠️ Weaknesses

Aerodynamic wind noise very present above 110 km/h (inherent to the design)
Flat windshield extremely vulnerable to stone chips
High AdBlue consumption on diesel versions
Stratospheric purchase price, insurance, and spare parts costs
Colossal weight (2.5 tons) rapidly wearing out consumables (brakes, tires)

🎯 Verdict

The Mercedes Classe G W463A is a rolling paradox, but that is what gives it its charm. If you opt for this model, the diesel engine (G 400 d as a priority, or G 350 d) is by far the smartest choice. The OM656 engine is a paragon of reliability, offers perfect torque to move this mass, and allows for decent range. However, avoid this diesel if you only drive in the city (risk of DPF/EGR clogging). The V8 versions (G 500 / G 63) are exhilarating but impose outrageous running costs. A passion purchase, but one that, thanks to its very low depreciation, proves to be less financially risky than it seems if maintenance is rigorous.
