21 MPG combined. That’s what you can expect from the 2015 Lincoln MKZ equipped with all-wheel drive and the 3.7L V6. It’s not a record-breaking number, but MKZ buyers have probably already considered it. This car isn’t bought for its fuel economy; it’s bought for its combination of comfort, distinctive styling, and a touch of American luxury. The AWD system adds weight and complexity, which affects fuel economy.

City and highway performance

The EPA estimates for the 2015 MKZ AWD 3.7L are 18 MPG in the city and 25 MPG on the highway. The city figure reflects how responsive the engine is in stop-and-go traffic, and also the fuel consumed by idling and repeated acceleration. The highway number is better, showing the engine’s ability to cruise efficiently at steady speeds. Drivers who spend most of their time on the open road will see better overall fuel economy than those who drive mostly in the city.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,100 for the 2015 Lincoln MKZ AWD 3.7L. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It assumes national average fuel prices. This is just an estimate; your actual fuel costs will vary based on your driving habits and local fuel prices. If you drive more aggressively or live in an area with higher gas prices, your annual fuel bill will be higher. More conservative drivers in areas with lower fuel costs could save money.

Real-world expectations

EPA figures provide a standardized benchmark, but real-world fuel economy often differs. Aggressive driving, especially frequent hard acceleration, will greatly reduce your MPG. Carrying extra weight in the car or using roof racks will also hurt fuel efficiency. Weather affects it too; cold temperatures can decrease fuel economy as the engine takes longer to warm up. Hilly routes will require more fuel than flat routes. The best way to know what to expect from your 2015 MKZ AWD is to monitor your own fuel consumption.

How it compares

In 2015, the Acura TLX SH-AWD with the 3.5L V6 had a slightly better combined EPA rating of 25 MPG. Buyers who wanted better fuel economy than horsepower might have considered the TLX. The Lexus ES 350, a front-wheel-drive competitor, had a combined EPA of 24 MPG, showing the fuel cost of all-wheel drive. However, the Lincoln offered a unique take on American luxury that the Acura and Lexus couldn’t match. Those considering other trims of this model can view MKZ MPG across all years here.

Tips to maximize efficiency

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressure at least once a month, and make sure it’s at the recommended pressure on the sticker inside your driver’s side door.

Avoid aggressive acceleration and braking. The 3.7L V6 responds quickly, but don’t floor it constantly. Gradual acceleration and smooth braking save fuel, especially in city driving. Watch traffic to avoid unnecessary stops and starts.

Reduce unnecessary weight. Remove any non-essential items from the trunk or backseat. Extra weight strains the engine, reducing fuel economy, especially when you accelerate. Clean out your car; you might be surprised by how much weight you’re carrying.

Consider using cruise control on the highway. Keeping a steady speed minimizes unnecessary acceleration and deceleration, which can greatly improve fuel economy on long trips. Disengage cruise control in heavy traffic or bad weather.

Follow the Lincoln’s maintenance schedule. Regular maintenance, including oil changes and air filter replacements, keeps the engine running efficiently. A poorly maintained engine will use more fuel. Follow the service intervals in your owner’s manual.
