Mercedes-Benz G-Class (2018-present) Pros and Cons

Pros	Cons
Amazing off-road ability	Hugely expensive to buy and run
Eye-catching retro styling	AMG versions are very thirsty
Luxurious cabin with lots of space	Not as sharp to drive as a Porsche Cayenne

Quick Summary

The Mercedes-Benz G-Class (2018-present) is a distinctive luxury SUV that traces its heritage back to the 1970s military Geländewagen. The current generation retains the iconic upright, boxy styling whilst introducing a thoroughly modern, luxurious interior packed with advanced technology. It blends serious off-road capability—featuring a ladder-frame chassis, low-range gearbox and locking differentials—with the refinement expected from a high-end Mercedes-Benz. Buyers can choose from powerful petrol and diesel engines, Mercedes-AMG performance variants, or the fully electric G 580 with EQ Technology offering 291 miles of range.

The G-Class is considerably more refined and civilled on the road than its predecessor, with improved steering precision and better body control. However, it remains an old-school off-roader at heart rather than a sporty SUV, preferring relaxed cruising to enthusiastic cornering. Running costs are substantial across all variants, with fuel consumption heavy on AMG models and maintenance firmly in luxury-car territory. Despite the premium pricing, the G-Class retains its value exceptionally well, and most owners appreciate its charismatic blend of rugged character and opulent luxury.

Best for: Wealthy buyers seeking a distinctive luxury SUV with genuine off-road capability, those valuing heritage and iconic styling, and drivers who prioritise presence and character over outright practicality.

Not ideal for: Budget-conscious buyers, those seeking lower running costs, drivers wanting the sharpest on-road handling, or anyone requiring seven-seat capacity.


Comparison vs Key Rivals



The Verdict

You should buy the G-Class if: You're seeking a distinctive luxury SUV with genuine off-road capability, value heritage and iconic styling, and prioritise presence and character over outright practicality.

Consider alternatives if: You're budget-conscious, seeking lower running costs, wanting the sharpest on-road handling, or requiring seven-seat capacity.

Competitive Position: The Mercedes-Benz G-Class occupies a unique position in the luxury SUV market. Whilst rivals like the Porsche Cayenne offer sharper handling and the Bentley Bentayga provides greater opulence, the G-Class stands apart through its authentic off-road heritage and distinctive character. It's considerably more expensive to run than most competitors and less agile on-road, yet its exceptional value retention, luxurious modern interior and extraordinary capability make it deeply charismatic. For buyers prioritising presence and heritage over pure practicality, the G-Class remains unmatched.
