23 MPG combined isn’t going to win the 2019 Jaguar XF 3.0L any fuel-sipping awards, but it reflects the car’s character: a British sedan that prioritizes performance and a premium driving feel over saving fuel. This isn’t a commuter car for chasing every last fraction of a mile per gallon. It’s transportation for someone who enjoys the journey more than the destination and appreciates a subtle growl from under the hood.

City and highway performance

The EPA estimates of 20 MPG in the city and 29 MPG on the highway accurately reflect the XF 3.0L’s driving dynamics. The city figure reveals the price you pay for stop-and-go driving with a supercharged V6, not ideal for maximum efficiency but offering confident acceleration when needed. The highway figure is more appealing, hinting at the XF’s ability to cruise comfortably at higher speeds. That 29 MPG is achievable on long stretches, further reinforcing the idea of this vehicle as a capable grand tourer.

Annual fuel cost

The estimated annual fuel cost for the 2019 Jaguar XF 3.0L is $2,500, calculated using the EPA’s assumptions of 15,000 miles driven per year and national average fuel prices. Keep in mind that this is just an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. Stop-and-go traffic, frequent hard acceleration, and premium fuel (which Jaguar recommends) can all significantly increase your yearly expenditure. However, when you compare that $2,500 to the cost of maintaining other vehicles, some XF buyers see the cost as a worthwhile investment.

Real-world expectations

While the EPA figures provide a benchmark, real-world fuel economy often deviates. XF owners often report figures slightly below the EPA’s 23 MPG combined, especially in areas with heavy traffic congestion. Aggressive driving will easily drop the average into the high teens. However, careful drivers prioritizing smooth acceleration and consistent speeds can sometimes match or even slightly exceed the highway estimate, showcasing the potential for better efficiency. Understanding driving habits is a key factor in how close real-world numbers align to the EPA estimates.

Fuel economy compared to similar vehicles

Compared to its rivals, the 2019 Jaguar XF 3.0L’s fuel economy sits squarely in the middle. The BMW 540i, with its turbocharged inline-six, achieves a similar 24 MPG combined, while the Mercedes-Benz E450, boasting a turbo V6, can offer close to 25 MPG. The Audi A6 3.0T, offering Quattro all-wheel drive standard, sits within the same range. While the difference may seem minor on paper, these small differences influence buyer decisions. For buyers prioritizing fuel economy above all else, the slightly better MPG of the Mercedes-Benz E450 might sway their decision. But others find the XF’s character and driving experience worth the relatively small fuel economy difference.

Tips to get better gas mileage

Using the XF’s “Eco” driving mode helps to significantly improve fuel economy, particularly in city driving. This mode adjusts the throttle response and shift mapping of the eight-speed automatic transmission, encouraging gentler acceleration and earlier upshifts. Engage Eco mode in congested areas and disengage for open roads when more spirited performance is desired. Small changes add up.

Consistent and moderate acceleration is important for achieving the best possible MPG. Avoid abrupt starts and stops, anticipating traffic flow and maintaining a smooth, steady speed. The supercharged V6 responds eagerly to throttle input, but a light foot will reward you with improved fuel efficiency. Also avoid letting the vehicle idle unnecessarily for extended periods, which rapidly consumes fuel.

Ensure your tires are properly inflated to the recommended pressure, typically found on a sticker inside the driver’s door or in the owner’s manual. Underinflated tires increase rolling resistance, forcing the engine to work harder and thus consuming more fuel. Regularly check and adjust tire pressure to optimize fuel efficiency and prolong tire life.

Minimize aerodynamic drag by removing any unnecessary items from the roof or trunk, such as roof racks or cargo carriers. These accessories disrupt airflow and increase fuel consumption, particularly at highway speeds. Keeping the XF as sleek and aerodynamic as possible will help to improve its fuel efficiency on longer journeys.

Consider using cruise control on highway drives to maintain a consistent speed and avoid unnecessary acceleration and deceleration. Cruise control can help to optimize fuel efficiency, especially on long, straight roads with minimal traffic. However, be mindful of traffic conditions and adjust speed accordingly to maintain a safe following distance.
