The Mercedes-Benz ML-Class W164, produced between 2005 and 2011, is a luxury mid-size SUV known for its powerful engines and off-road capabilities. However, like many vehicles in its class, fuel consumption is an important consideration for owners and potential buyers.

Fuel Efficiency Overview

The fuel consumption of the W164 varies depending on the engine type, driving conditions, and model year. Generally, the W164 offers a range of petrol and diesel engines, each with different fuel economy figures:

Petrol Engines: These tend to have higher fuel consumption, with average combined figures ranging from approximately 12 to 15 liters per 100 kilometers (L/100 km). The larger V8 engines, while delivering strong performance, are less fuel-efficient compared to smaller engines.

Diesel Engines: Diesel variants are more fuel-efficient, with combined consumption figures typically between 8 and 11 L/100 km. Diesel engines also provide better torque, which is beneficial for towing and off-road driving.

Factors Affecting Fuel Consumption

Several factors influence the actual fuel consumption of the W164:

Driving Style: Aggressive acceleration and high-speed driving increase fuel consumption significantly.
Load and Terrain: Carrying heavy loads or driving on rough, off-road terrain can reduce fuel efficiency.
Maintenance: Regular servicing, including timely oil changes, air filter replacements, and proper tire inflation, helps maintain optimal fuel economy.
Transmission: The automatic transmission in the W164 can impact fuel consumption depending on its condition and driving mode.

Real-World Consumption

In everyday use, many owners report fuel consumption figures slightly higher than official ratings, especially in urban driving conditions with frequent stops and starts. Highway driving tends to yield better fuel efficiency due to steady speeds.

Conclusion

While the Mercedes-Benz ML-Class W164 offers robust performance and luxury, its fuel consumption is moderate to high, especially for petrol models. Diesel variants provide better economy but still require mindful driving and maintenance to optimize fuel use.
