20 MPG combined won’t win any fuel economy awards, but for the 2015 Lincoln MKS AWD with its 3.5L V6, it’s a reasonable compromise for a specific buyer. This isn’t a vehicle purchased by those prioritizing less gas above all else. Instead, it caters to individuals seeking a comfortable, spacious sedan with the added security of all-wheel drive, even if that means accepting average fuel consumption.

City and highway performance

The EPA estimates for the 2015 Lincoln MKS AWD place city driving at 17 MPG and highway driving at 25 MPG. The lower city rating reflects the realities of stop-and-go traffic, where the MKS’s weight and the inefficiency of internal combustion engines at low speeds are apparent. The 25 MPG highway figure is more acceptable, demonstrating that the MKS can achieve decent mileage on long journeys, particularly when using cruise control to maintain a steady speed. The six-speed automatic transmission delivers smooth shifts in most driving conditions, though it lacks the technology of more modern eight- or ten-speed units found in newer luxury sedans.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Lincoln MKS AWD at $2,200. This figure is calculated based on driving 15,000 miles per year, using a national average fuel price. Of course, individual fuel costs can vary significantly depending on driving habits, local fuel prices, and the type of fuel used. While the MKS doesn’t require premium fuel, some owners might choose to use it in the hopes of slightly improved performance or fuel economy, further impacting their annual spending.

Real-world expectations

While the EPA provides a standardized baseline, real-world fuel economy can differ by several miles per gallon. Factors such as driving style, terrain, weather conditions, and vehicle maintenance all play a role. Aggressive acceleration, frequent braking, and driving in hilly areas will undoubtedly reduce fuel efficiency. Likewise, neglecting routine maintenance, such as tire inflation and oil changes, can negatively impact fuel economy. Expect the lower end of the EPA range if you drive primarily in the city with a heavy foot, but achieving or even slightly exceeding the highway estimate is possible with careful driving techniques on long, flat stretches.

How it compares

The 2015 Lincoln MKS AWD doesn’t have good fuel economy compared to its competitors. For example, the front-wheel drive Acura TLX with the 2.4L 4-cylinder manages 28 MPG combined, a significant advantage. Even the Lexus ES 350, a similarly sized luxury sedan, achieves 24 MPG combined. And all Lincoln fuel economy data shows that even within the Lincoln lineup, other models offer better numbers. The MKS buyer knows this going in. They prioritize the size, comfort, and all-weather capability. The Cadillac XTS, another competitor with available all-wheel drive, posts similar fuel economy figures around 19 MPG combined, suggesting that the MKS’s consumption is competitive within its specific segment of large, AWD luxury sedans. Potential buyers might also consider vehicles like the Buick LaCrosse, which offered comparable size and features, with FWD models achieving slightly better fuel economy in some model years. Refer to MKS MPG across all years to more thoroughly compare MPG metrics.

Tips to maximize efficiency

Given the 2015 Lincoln MKS AWD’s fuel consumption, using several strategies can help stretch each gallon of gasoline further. Avoid aggressive acceleration and braking. The MKS is a heavy vehicle, and rapid changes in speed require a significant amount of energy. Anticipate traffic flow and maintain a smooth, consistent speed whenever possible.

Regularly check and maintain proper tire inflation. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Refer to the sticker on the driver’s side doorjamb for the recommended tire pressure and check your tires at least once a month, especially during temperature changes.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Idling consumes fuel without covering any distance. While the MKS lacks modern automatic start/stop systems, manually shutting off the engine during prolonged stops can result in tangible fuel savings over time.

Reduce unnecessary weight. Carrying around excessive cargo in the trunk adds to the vehicle’s overall weight, which negatively affects fuel economy. Remove any unnecessary items to minimize the burden on the engine.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy, especially on long, flat stretches of road. It also prevents unintentional speeding, which can further reduce fuel efficiency. While the MKS’s six-speed transmission isn’t the most advanced, it still benefits from the consistent throttle input provided by cruise control.
