What's the Mercedes-Benz G-Class Like to Drive?

The Mercedes-Benz G-Class is engineered to deliver exceptional performance both on and off the road. The current lineup features powerful engines, including the G500 with its 4.0-litre twin-turbo V8 producing around 416 horsepower. This luxury SUV accelerates from 0-60 mph in just 5.6 seconds, impressive for such a substantial vehicle. The AMG variants push performance even further, with the G63 delivering extraordinary acceleration that rivals sports cars.

Where the G-Class truly excels is in its uncompromising capability. The three differential locks and low-range gearbox enable it to tackle terrain that would stop most other luxury SUVs. On road, the adaptive suspension system provides surprisingly refined handling for such a tall, heavy vehicle. The steering is precise and confidence-inspiring, while the brakes offer strong stopping power. Modern G-Class models strike an excellent balance between comfort and control, making them surprisingly pleasant to drive daily despite their imposing dimensions.

Is the Mercedes-Benz G-Class Expensive to Run?

Owning a G-Class means accepting premium running costs that reflect its luxury positioning and powerful engines. Fuel economy is modest, with real-world consumption typically ranging from 22-25 MPG depending on driving conditions and engine variant. The powerful V8 engines prioritise performance over efficiency, so expect regular visits to the petrol station. Insurance costs are substantial due to the high purchase price and repair costs, placing most variants in the highest insurance groups.

The initial purchase price starts around £140,000 for a new G500, positioning it firmly in the luxury market. This significant investment reflects the vehicle’s exceptional build quality, advanced technology, and iconic status. Maintenance costs are higher than mainstream SUVs, though Mercedes’ reputation for engineering excellence means reliability is generally good. When considering total ownership costs, the G-Class holds its value exceptionally well, making it a sound investment for those who appreciate its unique combination of luxury and capability. Flexible car finance options can help make ownership more accessible.

Mercedes-Benz G-Class Practicality & Boot Space

For such an imposing vehicle, the G-Class offers impressive practical benefits. The 667-litre boot provides ample space for luggage, sports equipment, or shopping. The rear seats fold to expand cargo capacity significantly when needed. The high driving position offers excellent visibility, making it easier to navigate tight spaces despite the vehicle’s substantial dimensions. Numerous storage compartments throughout the cabin accommodate everyday items conveniently.

Where the G-Class shows its unique character is in its genuine off-road capability. Unlike many luxury SUVs that prioritise road manners, the G-Class maintains serious adventure credentials with proper ground clearance, wading depth, and approach angles. This makes it perfect for owners who genuinely use their SUV for outdoor pursuits. For families, the spacious interior comfortably seats five adults, though the rear-hinged spare wheel carrier can make accessing the boot slightly awkward in tight parking situations. Among used Mercedes cars, the G-Class stands out for combining luxury with genuine utility.

After three years of ownership, the G-Class still makes me smile every time I see it. The build quality is absolutely exceptional and it handles everything from school runs to mountain trails with equal confidence. Yes, it drinks fuel, but the experience is worth every penny.
