The 2015 Jaguar XJ AWD with the 3.0L V6 gets 19 MPG combined and while not the most fuel-efficient car, it’s also not trying to be. This XJ prioritizes luxury, style, effortless power, and refined comfort. The buyer is likely aware of this trade-off.

City and highway performance

The EPA estimates the 2015 XJ AWD at 16 MPG in the city and 24 MPG on the highway. The city number reflects the engine’s power and the nature of stop-and-go driving with a large engine. You likely won’t see much better than 16 MPG in the city. However, the highway figure is more attainable. Cruising at 70-75 mph should get you close to 24 MPG, especially if you use cruise control. The eight-speed automatic transmission helps by keeping the engine in its most efficient rev range at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Jaguar XJ AWD at $3,050. This is based on driving 15,000 miles per year and using the national average fuel price for premium gasoline, which this car requires. Your actual fuel costs could be higher or lower depending on your driving, the roads you drive on, and gas prices in your area. Driving fewer miles will lower the cost, and vice versa. Aggressive driving will also increase your fuel bill. The $3,050 figure is a useful benchmark, but personalize your expectations.

Real-world expectations

Real-world fuel economy for the 2015 XJ AWD often mirrors the EPA’s numbers, but some variation is normal. Drivers who accelerate quickly will likely see numbers below the EPA estimates, especially in the city. On the other hand, those who accelerate smoothly, anticipate traffic, and cruise efficiently might do slightly better. The car’s computer provides a running average MPG display, which can help you monitor fuel consumption and identify areas to improve. Expect fluctuations based on driving style and conditions this is normal.

How it compares

When considering the 2015 XJ AWD, compare it to its competitors’ fuel economy. The 2015 BMW 740i xDrive achieves around 22 MPG combined, a slight improvement. The Audi A8 with its 3.0T engine delivers approximately 21 MPG combined, which bridges the gap. A Mercedes-Benz S550 4Matic, even with a larger engine and more power, can surprisingly get close to 20 MPG combined. These comparisons show the XJ’s fuel consumption in its class of large, luxurious, and all-wheel-drive sedans. The unique British character, spacious comfort, and distinctive styling are key reasons why buyers choose the XJ not class-leading efficiency. See XJ MPG across all years for a more comparison.

Tips to maximize efficiency

Gentle acceleration is key to using less gas in the XJ. The supercharged V6 offers plenty of low-end torque, allowing you to build speed smoothly without pressing the accelerator pedal too hard. Avoid sudden acceleration since it wastes gas.

Maintain a consistent speed on the highway use cruise control. This helps prevent unnecessary speed changes and optimizes fuel economy. And make sure you are using the correct tire pressure. Underinflated tires create more rolling resistance, which uses more fuel.

Reduce weight in the vehicle. Extra cargo impacts fuel economy. Remove any items that are not essential. Keep your car’s maintenance up to date. A properly maintained engine runs more efficiently.

Anticipate traffic and brake smoothly. Look ahead and anticipate traffic patterns to avoid sudden braking and acceleration. Instead, gradually reduce speed, letting the car coast when possible.

Consider Jaguar’s Eco mode, if equipped. While the XJ is designed for driving pleasure, Eco mode changes the shift points and throttle response to slightly help with fuel economy. If you’re interested in other Jaguars, check out all Jaguar fuel economy data.
