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 one of the most distinctive luxury SUVs available today. Tracing its roots back to the 1970s military Geländewagen, the current generation retains the iconic upright, boxy styling whilst introducing a thoroughly modern, luxurious interior. It blends serious off-road capability with high-end Mercedes-Benz technology, featuring a ladder-frame chassis, low-range gearbox and locking differentials. 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 dramatically 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, prioritising character over agility. The cabin is exceptionally well-built with generous space, though the side-hinged rear door requires careful parking. Running costs are substantial, with high purchase prices, significant fuel consumption on AMG models, and luxury-level servicing expenses. Despite this, the G-Class retains its value exceptionally well, and few vehicles combine old-school character, opulent luxury and road presence quite like this one.

Best for: Wealthy buyers seeking a distinctive luxury SUV with genuine off-road capability, those valuing iconic styling and charisma over pure practicality, and owners able to absorb substantial running costs.

Not ideal for: Budget-conscious buyers, those prioritising fuel economy or low running costs, drivers seeking sharp handling comparable to a Porsche Cayenne, or anyone needing a practical seven-seat option.


Comparison vs Key Rivals



The Verdict

You should buy the G-Class if: You're a wealthy buyer seeking a distinctive luxury SUV with genuine off-road capability, value iconic styling and charisma, or want a vehicle that stands out from conventional luxury alternatives.

Consider alternatives if: You prioritise fuel economy and low running costs, seek sharp handling comparable to a Porsche Cayenne, need a seven-seat option, or are budget-conscious.

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 refinement, the G-Class stands alone in combining old-school off-road character with opulent luxury. It's far more expensive to buy and run than most competitors, yet its exceptional value retention and distinctive appeal justify the investment for those who appreciate its charisma. The G-Class is not the rational choice, but that's precisely why owners love it.
