G-Class Engines Through the Generations
W463 pre-2018
ran M113/M273 petrol V8s and OM642 diesel across its long production run, with the M157-powered G63 AMG as flagship. W463 II (2018–Present): introduced the standard M176 V8 alongside the AMG-only M177, with OM656 diesel and a genuinely new M256 turbo straight-six petrol tier completing the current range.
G-Class Engine Buying FAQs
7 confirmed engine families across two generations, spanning legacy M113/M273 V8s and OM642 diesel through to the current M176/M177/M256/OM656 range.
Use the registration checker on this page — the 2018 second-generation redesign is the critical dividing line, with M176 (standard) vs M177 (AMG-only) as the key distinction within the current range.
Legacy petrol/diesel applications favour used. Current V8 (M176/M177) applications more commonly favour reconditioned given complexity and vehicle value.
Reconditioned engines carry a 12-month, unlimited-mileage warranty on internal mechanical components. UK mainland delivery by kerbside pallet, typically 2–4 working days, with 14-day uninstalled returns.
