21 MPG combined doesn’t make the 2021 Mercedes-Benz Metris (Cargo Van, Long Wheelbase) a fuel sipper. But for businesses needing a relatively compact, yet immensely practical cargo hauler, it’s an acceptable compromise. The Metris occupies a sweet spot between the bulk of full-size vans and the cramped quarters of smaller, purely commercial offerings. It offers a generous cargo area, a manageable footprint for urban environments, and that coveted three-pointed star on the grille. Fleet managers and small business owners don’t typically prioritize fuel economy above all else; payload capacity, maneuverability, and reliability are often higher on the list. And within that context, the Metris plays its role.

City and highway performance

The EPA estimates that the Metris Cargo Van LWB achieves 19 MPG in the city and 23 MPG on the highway. These figures are indicative of the demands placed on the 2.0L turbocharged 4-cylinder engine. In urban environments, stop-and-go traffic and frequent acceleration take their toll, while more consistent highway speeds allow the engine to operate more efficiently. The 9-speed automatic transmission is programmed to keep the engine in its most efficient range as much as possible; however, it’s always working against the van’s weight and aerodynamic profile.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Mercedes-Benz Metris Cargo Van LWB at $2,750. This figure is based on driving 15,000 miles per year and assumes the use of regular unleaded gasoline at national average prices. Of course, actual fuel costs may vary considerably depending on individual driving habits, local fuel prices, and the specific demands placed on the vehicle. A delivery service operating primarily in a dense urban core, for example, will likely see higher fuel costs than a contractor who uses the Metris primarily on highway routes. Before buying a Metris, research METRIS MPG across all years so you know what to expect.

Real-world expectations

Beyond the EPA estimates, real-world fuel economy for the Metris can fluctuate widely. Factors like payload weight, driving style, and even tire pressure can significantly impact fuel consumption. A Metris consistently loaded with heavy equipment will naturally consume more fuel than one carrying lighter loads. Aggressive driving habits, such as rapid acceleration and hard braking, will also reduce efficiency. Owners who prioritize smooth, consistent driving and adhere to recommended maintenance schedules are more likely to achieve numbers closer to the EPA estimates.

How it compares

Compared to other vans in its class, the Metris’s fuel economy is neither exceptionally good nor particularly bad. The Ford Transit Connect, for example, a smaller but still practical van, achieves around 26 MPG combined with its 2.0L engine. However, the Transit Connect offers significantly less cargo space than the Metris. Full-size vans like the Ford Transit 150 with the 3.5L V6 average closer to 17 MPG combined, highlighting the Metris’s position as a more fuel-efficient alternative for businesses that don’t require the sheer bulk of a larger van. Ram ProMaster City comes in at 24 MPG combined which makes it a more economical van for a similar use-case. Before choosing your next work van, compare all Mercedes Benz fuel economy data to make sure you’re making the right decision.

Tips to maximize efficiency

Regular maintenance is key to getting good gas mileage in the Metris. Ensure that the tires are properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce fuel efficiency. And keep up with scheduled oil changes and other maintenance items, as a well-maintained engine will operate more efficiently.

Minimize unnecessary weight. The more weight the Metris carries, the harder the engine has to work, reducing fuel economy. Remove any unnecessary items from the cargo area to lighten the load and improve efficiency. This is especially important for businesses that often carry a mix of heavy and light loads.

Drive smoothly and avoid aggressive acceleration and braking. Anticipate traffic flow and maintain a consistent speed whenever possible. Avoid sudden bursts of acceleration or hard braking, as these actions consume more fuel. Using cruise control on the highway can also help maintain a consistent speed and improve fuel economy.

Consider the route you take. Planning routes that avoid stop-and-go traffic and minimize idling can significantly improve fuel economy. Using navigation apps to find the most efficient routes can save both time and fuel. This is particularly useful for businesses operating in urban areas with heavy traffic congestion.
