The 2017 Jaguar XF 3.0L 6-cylinder gets 23 MPG combined. While not class-leading, this number is a decent trade-off if you want a refined driving experience and unique styling over the best possible fuel efficiency. The XF, especially with this engine, appeals to people who appreciate Jaguar’s heritage and prestige. The target buyer understands that effortless power and elegant design come at a cost. It’s not a deal-breaker, but a conscious choice.

City and highway performance

The split between city and highway driving reveals more about the XF’s character. The EPA rates the 2017 Jaguar XF 3.0L at 20 MPG in the city. Stop-and-go driving takes a toll, and the XF’s supercharged 3.0-liter V6 needs premium fuel to deliver its power. On the open road, the XF does better, achieving 29 MPG on the highway. This makes it a good choice for longer commutes or weekend road trips where the smooth-shifting eight-speed automatic transmission can settle into a fuel-efficient cruising gear. The highway MPG shows the car’s ability to cover ground easily, a Jaguar hallmark.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 Jaguar XF 3.0L 6-cyl is $2,500. This is based on driving 15,000 miles per year, using national average fuel prices for premium gasoline, and a mix of 55% city and 45% highway driving. This is a significant expense. However, it gives potential owners a benchmark for their budget. Fuel costs will vary based on driving habits, local fuel prices, and annual mileage.

Real-world expectations

The EPA estimates are a baseline, but your actual fuel economy will likely differ. Factors like driving style, tire pressure, climate control, and terrain can all change real-world MPG. Aggressive acceleration, frequent hard braking, and speeding will hurt your fuel efficiency. Consistently driving in “Dynamic” mode, which sharpens throttle response and holds gears longer, will also reduce fuel economy. Owners who want better efficiency should drive smoothly and keep their XF maintained.

How it compares

The 2017 Jaguar XF competes with other mid-size luxury sedans, where fuel economy is often secondary to performance and prestige but still important. The 2017 BMW 540i xDrive, with its turbocharged inline-six, gets around 23 MPG combined, like the XF, but gets slightly better city MPG, hitting 20. The Mercedes-Benz E300, with its turbocharged four-cylinder, does much better, achieving 25 MPG combined. The Audi A6 2.0T, also with a four-cylinder engine, also gets better fuel economy, around 28 MPG combined. These comparisons show the fuel consumption trade-off for the XF’s more powerful supercharged V6. Buyers should weigh this against the engine’s performance character and the Jaguar’s driving experience. Compare the XF MPG across all years.

Tips to maximize efficiency

The Jaguar XF’s supercharged 3.0-liter engine responds well to smooth driving. Avoid fast acceleration from a stop and try to anticipate traffic to minimize braking. Gradually increase your speed and maintain a consistent pace, especially on the highway. These small changes can affect your fuel consumption.

Make sure your tires are properly inflated to the recommended pressure on the driver’s side door jamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and using more gas. Regularly check your tire pressure, especially during temperature changes. Regular maintenance will have a huge impact. Poor engine maintenance means poor fuel economy.

Use cruise control on long highway stretches. This helps maintain a consistent speed, preventing unintentional acceleration and deceleration that can waste fuel. Setting the cruise control at a reasonable speed within the legal limits allows the engine to operate at its most efficient range, maximizing your MPG. This is especially useful on long, flat stretches of highway.

Consider using the Jaguar’s “Eco” driving mode, if equipped. This mode optimizes vehicle settings like throttle response and transmission shift points to prioritize fuel efficiency. While it may slightly reduce performance, it can improve your MPG, especially during city driving. This is a worthwhile option when you want to minimize fuel consumption without sacrificing comfort or safety. If you need more fuel efficiency information be sure to review all Jaguar fuel economy data.
