22 MPG combined isn’t great for a modern vehicle, but it reflects the 2020 Mercedes-Benz Metris Cargo Van’s purpose. It’s not a lifestyle-focused SUV for suburban errands, it’s a workhorse built for businesses needing to haul serious cargo in a reasonably compact package. Fuel economy, while important, often takes a backseat to payload capacity, maneuverability in urban environments, and overall reliability. The Metris serves a specific niche, and its fuel consumption is a calculated trade-off for those buyers.

City and highway performance

The EPA estimates 21 MPG in the city and 24 MPG on the highway for the 2020 Metris Cargo Van with the long wheelbase and 2.0L four-cylinder engine. These figures highlight the engine’s relatively narrow powerband. City driving, with its constant stop-and-go, puts a heavier strain on the engine, hindering fuel efficiency. The highway number is slightly better, but the van’s boxy shape and considerable weight still contribute to aerodynamic drag, preventing it from achieving truly impressive MPG at higher speeds. The seven-speed automatic transmission helps keep the engine in its optimal range, but physics play a significant role in the Metris’s fuel consumption.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mercedes-Benz Metris (Cargo Van, LWB) 2.0L 4-cyl at exactly $2,650. This figure is based on driving 15,000 miles per year, using a national average fuel price. This number represents a significant operating expense for businesses relying heavily on the Metris. Fleet managers will need to factor this annual cost into their overall budget, alongside maintenance, insurance, and other operational expenses. The $2,650 is an estimate, of course, and the actual cost may vary depending on driving habits and local fuel prices. For example, those who are more judicious with their acceleration and less aggressive on the brakes may see this fall lower. Others could spend far more.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary significantly. Factors like load weight, driving style, and terrain all impact fuel consumption. Metris drivers frequently carry substantial payloads, which invariably reduces MPG. Aggressive acceleration and frequent hard braking also take their toll. Businesses operating in hilly areas or experiencing heavy traffic congestion will likely observe fuel economy below the EPA estimates.

Conversely, drivers who adopt a conservative driving style and maintain consistent speeds on relatively flat terrain may see slightly better results.

How it compares

The Metris occupies a unique space in the market, but comparing it to similar vehicles provides context. The Ford Transit Connect, for example, boasts a significantly better EPA combined rating of 26 MPG with its 2.0L engine. However, the Transit Connect offers less cargo space and a lower payload capacity than the Metris. Stepping up to a full-size van like the Ford Transit 150 with the base 3.5L V6 sees MPG drop to around 17 MPG combined, highlighting the Metris’s position as a good compromise between size and efficiency for some buyers. Even checking out all Mercedes Benz fuel economy data shows the Metris is near the bottom in fuel economy.

Tips to maximize efficiency

Regular maintenance is critical for optimizing fuel economy. Ensure the engine is properly tuned, the tires are correctly inflated, and the air filter is clean. Neglecting these basic maintenance tasks can lead to decreased efficiency and increased fuel consumption. A well-maintained van simply runs more efficiently.

Avoid unnecessary idling. Letting the engine run while stationary consumes fuel without covering any distance. If you anticipate being stopped for more than a minute, turn off the engine. Frequent idling, especially with a loaded van, can dramatically reduce overall MPG. Instead of idling, consider investing in battery-powered accessories that can run without the need to turn the engine on.

Drive smoothly and anticipate traffic flow. Avoid rapid acceleration and hard braking, and maintain a consistent speed whenever possible. Aggressive driving burns more fuel. By anticipating traffic conditions and maintaining a steady pace, you conserve fuel and minimize wear and tear on the vehicle. Think of it as lengthening not only your tank of petrol but also the life of your brakes.

Reduce weight. Every extra pound adds to the engine’s workload, decreasing fuel economy. Remove any unnecessary items from the cargo area to minimize weight. This is especially important for businesses that frequently carry heavy loads with their METRIS MPG across all years. Even small reductions in weight can cumulatively improve fuel efficiency over time.
