Core summary
U.S. MY2025 updated Mercedes-AMG G 63. Source-based specification and buying analysis.
Choose the G 63 because you want this particular vehicle, then test whether its access and footprint suit everyday life. A powerful engine cannot resolve a garage or passenger-entry mismatch.
History & generations
Mercedes announced the updated G-Class in 2024 for U.S. MY2025. This guide separates the revised G 63 from earlier examples with a similar silhouette.
Body, platform & design
A familiar outline makes visual identification unreliable. Confirm model year and build equipment instead of assuming every recently registered G-Class has the updated systems.
Engine & drivetrain
The G 63 retains a 4.0-liter biturbo V8 rated at 577 hp and 627 lb-ft, now with a 48-volt integrated starter-generator system.
Trim differences
Ask for a separate explanation and price of chassis options. Do not infer that an optional suspension shown in launch coverage is fitted to every stock vehicle.
Interior & seating
Try climbing in and out several times, then test rear passengers and luggage. Include a narrow parking space where the doors cannot be opened fully.
Efficiency & range
Mild-hybrid assistance is not a plug-in electric-range claim. Calculate fuel spending from the appropriate certified rating rather than treating the update as an electric commuting solution.
Safety & equipment
Learn the assistance and off-road controls before attempting unfamiliar terrain. A performance badge does not substitute for route assessment, suitable tires or instruction.
Strengths
The convincing purchase is one where the distinctive G-Class experience is worth the practical trade-offs to you. It is not automatically the most rational way to obtain a spacious premium vehicle.

Considerations
On a used G 63, seek a specialist inspection of modifications, maintenance and chassis condition. A recent-looking exterior cannot confirm either originality or mechanical health.
Recommended use
An urban owner should begin with parking and entry; a terrain-focused owner should document the actual route and equipment needs before spending on optional hardware.
Rivals & related
Compare the updated G 63 with an earlier V8 only after identifying the 48-volt change and fitted equipment. Keep electric G-Class specifications in a separate comparison.
FAQ
Is this G 63 battery-electric? No. This reference concerns the V8 mild hybrid; descriptions of an electric G-Class should not be attached to it.
