The 2015 Lincoln MKX AWD with the 3.7L V6 achieves 19 MPG combined. This vehicle isn’t purchased for excellent fuel efficiency; it’s a comfortable, quiet, and well-appointed crossover. It’s aimed at buyers who prioritize a smooth ride and luxurious amenities over class-leading MPG. These buyers accept the fuel consumption as the price for a premium experience.

City and highway performance

The MKX gets an EPA-estimated 17 MPG in the city and 23 MPG on the highway. These figures reflect the vehicle’s characteristics and its intended use. The 17 MPG city rating is typical for a V6-powered all-wheel drive crossover of this size and weight, especially since this generation MKX uses a traditional hydraulic-assist power steering system, which can draw more energy than modern electric-assist systems. Highway driving sees a more respectable 23 MPG, attainable when cruising at steady speeds. The six-speed automatic transmission, while not the most advanced unit available at the time, is competent enough to keep the engine in its optimal range, resulting in reasonable highway efficiency if you avoid aggressive acceleration.

Annual fuel cost

Based on the EPA’s estimates, the annual fuel cost for the 2015 Lincoln MKX AWD 3.7L V6 is approximately $2,300. This figure is calculated assuming 15,000 miles driven per year, using the national average fuel prices at the time of calculation. Drivers exceeding this mileage can expect a higher annual fuel cost, while those driving fewer miles will see a corresponding decrease. Gas price changes directly impact the cost to keep the MKX running.

Real-world expectations

The EPA provides a standard, but real-world fuel economy can vary significantly based on driving habits, road conditions, and maintenance. Aggressive acceleration, frequent braking, and carrying extra weight will negatively impact fuel efficiency. Neglecting recommended maintenance, like tire inflation and oil changes, can also contribute to lower MPG. Owners who primarily drive in congested urban environments may find it challenging to consistently achieve the EPA’s 17 MPG city rating. However, those who predominantly drive on open highways at consistent speeds will likely see results closer to, or even slightly above, the 23 MPG highway figure.

How it compares

The 2015 Lincoln MKX’s fuel economy is roughly in the middle of its class. The Acura RDX with its 3.5L V6, for example, achieves slightly better numbers with EPA ratings of 20 MPG combined, 19 city, and 28 highway for the front-wheel drive variant. The Lexus RX 350, known for its reliability and efficiency, also has a slight edge, with an EPA-estimated 22 MPG combined. Meanwhile, the Cadillac SRX, another popular luxury crossover, has the MKX’s numbers, often delivering similar real-world MPG. For the MKX buyer, a difference of 2-3 MPG typically isn’t a deal-breaker; ride quality, styling, and available features often outweigh modest fuel economy discrepancies.

Tips to maximize efficiency

Gentle acceleration and braking are key to maximizing fuel economy in the MKX. The 3.7L V6 delivers ample power, but using it frequently will burn through fuel. Anticipate traffic flow and avoid unnecessary hard stops and starts. Using cruise control on the highway helps maintain a consistent speed, optimizing fuel consumption. This is especially effective on long trips where speed variations are less frequent.

Ensure that your tires are properly inflated to the manufacturer’s recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, especially during temperature changes, as pressure can change significantly with the weather. Proper inflation also improves tire life and handling.

Reduce usage of accessories that place a load on the engine. Air conditioning, in particular, can substantially reduce fuel economy, especially in city driving. Use it carefully, and when possible, take advantage of natural ventilation. Other power-draining accessories like heated seats and rear defrosters should also be used sparingly.

Maintain your MKX according to the manufacturer’s recommended service schedule. Regular oil changes, air filter replacements, and tune-ups ensure that the engine is running efficiently. A well-maintained engine burns fuel more cleanly and effectively, improving MPG. Addressing any mechanical issues promptly prevents them from escalating into larger problems that could impact fuel economy.
