21 MPG combined is a respectable, but not stellar, figure for the 2015 Lincoln MKZ with the 3.7L V6 and front-wheel drive. Those drawn to this specific MKZ aren’t prioritizing ultimate fuel efficiency. They’re seeking a comfortable, stylish, and reasonably powerful luxury sedan with a hint of American flair, and they’re willing to accept mid-pack fuel economy to get it.

City and highway performance

The EPA estimates for the MKZ V6 are 18 MPG in the city and 27 MPG on the highway. The city figure reflects the engine’s thirst when navigating stop-and-go traffic, a common scenario for suburban commuters who make up a large part of this car’s buyer base. The highway MPG is more palatable, suggesting the MKZ can be a relaxed and efficient cruiser on longer trips. What these numbers don’t reveal is the responsive nature of the 3.7L V6; driving with a heavy foot to exploit its power will certainly yield lower numbers than those on the sticker.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Lincoln MKZ V6 FWD is $2,100. This figure assumes 15,000 miles of driving per year, with a blend of city and highway miles mirroring the EPA test cycle. The calculation is based on national average fuel prices, which fluctuate, so your actual costs may vary depending on where you live and your driving habits. Still, it gives you a clear benchmark against which to compare other vehicles and is useful in estimating the cost of ownership.

Real-world expectations

Getting the EPA estimates will require a deliberate effort. Real-world results for the MKZ V6 FWD often nudge slightly below the 21 MPG combined rating, particularly with aggressive driving or extended idling. The 6-speed automatic transmission is generally smooth but designed more for comfort than outright efficiency. Passengers and cargo will also impact fuel economy, especially on hills or during frequent acceleration. Someone who prioritizes fuel economy and drives accordingly can achieve the stated MPG, but those who regularly experience heavy stop-and-go traffic, mountainous roads, or simply enjoy the V6’s power can expect less favorable results.

How it compares

Several competitors offer more fuel-efficient alternatives for the 2015 model year. The Acura TLX with the 2.4L 4-cylinder engine, for example, boasts a combined EPA rating of 28 MPG, a noticeable improvement that’s important for buyers who are cross-shopping. The Lexus ES 350, while featuring a V6, achieves a slightly better EPA combined rating of 24 MPG, due in part to its more advanced transmission and engine management. Even considering other Lincoln models, the MKZ Hybrid offers significant fuel savings, achieving an EPA combined rating of 40 MPG. The fuel-conscious luxury buyer likely considers these alternatives. But, they might reject these alternatives due to the Lincoln’s styling, quiet cabin, or the specific horsepower provided by its particular V6.

Tips to maximize efficiency

Avoid hard acceleration. The 3.7L V6 is rewarding when pushed, but frequent bursts of speed noticeably decrease fuel economy. Aim for smooth, gradual acceleration, especially when starting from a stop or merging onto the highway. Anticipate traffic flow to minimize the need for sudden braking.

Look far ahead and coast whenever possible to avoid unnecessary stops. Maintain proper tire inflation. Underinflated tires increase rolling resistance, dragging down fuel economy. Check your tire pressures regularly (ideally weekly) and inflate them to the recommended pressure listed on the sticker inside the driver’s side doorjamb. This simple step can make a small but consistent difference.

Reduce idling time. Idling engines consume fuel without covering any distance. If you anticipate stopping for more than a minute or two, turn off the engine. Modern cars restart quickly and efficiently, making this practice far less inconvenient than it once was. Turn off the ignition at long stop lights, drive-throughs, or while waiting for someone in the car. Use cruise control judiciously.

Cruise control can improve fuel economy on flat, open highways. However, it can be detrimental in hilly terrain, where it may aggressively downshift and burn more fuel to maintain speed. Monitor fuel efficiency and adjust speed as necessary. Driving at a steady speed with minimal fluctuations will lead to better fuel economy.
