The 2018 Mercedes-Benz Metris Passenger Van gets 21 MPG combined. While this won’t win any fuel efficiency awards, fleet managers and families reluctantly accept it as a cost of doing business. This vehicle isn’t bought for fuel efficiency. It’s bought because it can reliably haul up to eight people and their gear, offering a level of refinement many competitors lack. Buyers prioritize space, practicality, and Mercedes-Benz dependability over saving gas. They understand the trade-off.

City and highway performance

The EPA estimates the 2018 Metris Passenger Van at 19 MPG in the city and 23 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, which impacts the fuel consumption of a vehicle this size. The 23 MPG highway rating is more palatable, especially on longer road trips where the Metris cruises comfortably. However, drivers can expect these numbers to change based on driving style, payload, and terrain. A fully loaded Metris climbing a mountain pass will see much lower fuel economy than an empty one on a flat highway.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Mercedes-Benz Metris Passenger Van at $2,750. This is based on 15,000 miles of driving per year, using national average fuel prices. It’s a useful benchmark for comparing the Metris to other vehicles, but individual costs will vary depending on local fuel prices and driving habits. Drivers who mostly use their Metris for short trips in the city may find their annual fuel costs exceeding this estimate, while those who mainly use it for highway travel might find it lower. This figure does not account for the cost of premium fuel, if used.

Real-world expectations

What can you actually expect in real-world driving? Owners report figures that often fall near the EPA’s estimates. A light foot and highway driving can yield numbers close to 23 MPG, while aggressive acceleration and city congestion can easily drag the average down below 19 MPG. Tire pressure and regular maintenance also play a role. It won’t get Prius-like efficiency, but consistent and mindful driving habits will certainly make a difference. Adding aftermarket accessories like roof racks or oversized tires will negatively impact fuel economy.

How it compares

Compared to other passenger vans, the 2018 Metris is competitive but not class-leading. The Ford Transit Connect Wagon, with its available 2.0L EcoBoost engine, achieves a slightly better 24 MPG combined, making it more fuel-efficient. The larger Ford Transit (with a gasoline engine) offers more space but typically achieves lower fuel economy, closer to 16-18 MPG combined. The Dodge Grand Caravan, before it was discontinued, offered comparable space and utility, with fuel economy around 20 MPG combined. Buyers often compare these vehicles based on price, space, and features, with fuel economy being one factor. For more information, check out all Mercedes Benz fuel economy data.

Tips to maximize efficiency

Avoid aggressive acceleration. The Metris isn’t a sports car, and stomping on the accelerator only wastes fuel. Gentle and gradual acceleration allows the 7-speed automatic transmission to shift smoothly and efficiently, keeping the engine in its most economical operating range. Think of it as driving a small bus, not a hot hatch.

Maintain proper tire pressure. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels. This simple task can improve your fuel economy and extend the life of your tires.

Reduce unnecessary weight. Carrying around extra cargo adds weight, which directly impacts fuel consumption. Clean out any unnecessary items from your Metris, especially before long trips. Every pound counts.

Plan your routes strategically. Avoid rush hour traffic and congested areas whenever possible. Stop-and-go driving hurts fuel economy. Using navigation apps that provide real-time traffic updates can help you identify and avoid congested routes, saving you time and fuel. And for a better view of all years, check the METRIS MPG across all years.

Service the engine regularly. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule for oil changes, air filter replacements, and other routine services. A clean air filter, fresh oil, and properly functioning spark plugs can all contribute to improved fuel economy.
