The 2016 Jaguar XJL 3.0L gets 21 MPG combined. It’s not going to win any gas mileage awards, but realistically, you’re probably not looking at a long-wheelbase XJL primarily for fuel efficiency. This car offers presence, luxury, and the quiet confidence of a powerful engine, all within a uniquely British design. Owners tend to prioritize a smooth ride, distinctive styling, and a prestigious badge. Fuel economy is often viewed as simply a cost of doing business.

City and highway performance

EPA estimates offer a more detailed look at the XJL’s fuel consumption: 18 MPG in the city and 27 MPG on the highway. The city figure reflects the reality of navigating stop-and-go traffic, where the XJL’s weight and frequent acceleration from a standstill impact fuel economy. On the open road, the supercharged V6 settles into a more fuel-efficient speed. This allows you to cover long distances with decent gas mileage. The eight-speed automatic transmission helps in both driving conditions, keeping the engine in an optimal range for either power or efficiency. While 27 MPG on the highway isn’t amazing, it’s good enough for long trips, limiting how often you’ll need to stop for gas.

Annual fuel cost

The EPA estimates that the 2016 Jaguar XJL 3.0L will cost $2,750 per year in fuel. This is based on driving 15,000 miles per year with a mix of city and highway driving, using the national average fuel price at the time of calculation. This annual cost gives potential buyers an idea of the ongoing running expenses of this model. Remember that your actual fuel costs can change depending on your driving habits, the type of fuel you use, and local fuel prices. Checking all Jaguar fuel economy data will give you more information.

Real-world expectations

EPA figures serve as a standard, but real-world fuel economy can vary. Aggressive driving, frequent short trips, and long periods of idling can all lower your MPG a lot. Driving gently, keeping a steady speed on the highway, and properly inflating your tires can help you get numbers closer to, or even a little better than, the EPA estimates. The XJL’s supercharged engine is responsive and likes to be revved, which can be tempting. However, more enthusiastic throttle use almost always hurts fuel economy.

How it compares

The 2016 XJL’s fuel economy places it in a specific spot among large luxury sedans. The BMW 740i from the same year, with its turbocharged inline-six, achieves a slightly better 24 MPG combined. The Mercedes-Benz S550, with a V8, gets around 20 MPG combined. Even the Lexus LS 460, known for its reliability, gets about 19 MPG combined. Buyers of these brands know that they’re not mainly focused on gas mileage. They value comfort, performance, and brand appeal. Still, knowing the differences helps put the XJL’s fuel consumption in context. You can also researchXJL MPG across all years to see how it compares over time.

Tips to maximize efficiency

Use the XJL’s drive modes. Eco mode will change the throttle response and shift points to prioritize fuel efficiency. This might slightly reduce the car’s performance, but it can make a real difference on long trips, especially on the highway. It might be tempting to drive in Dynamic all the time, but save that for special occasions.

Make sure your tires are inflated properly. Regularly checking and keeping the correct tire pressure not only improves fuel economy, but also improves handling and makes your tires last longer. The recommended tire pressure is usually on a sticker inside the driver’s side doorjamb.

Keep idling to a minimum. Letting your XJL idle for a long time, especially when the engine is cold, wastes gas. If you’re going to be stopped for more than a minute, it’s usually better to turn off the engine.

Service the engine on schedule. A well-maintained engine runs more efficiently. Doing the manufacturer’s recommended service, like oil changes and air filter replacements, will help improve fuel economy and keep the engine running smoothly for a long time.

Anticipate traffic. Smooth acceleration and braking save fuel compared to aggressive stop-and-go driving. If you anticipate traffic and keep a safe following distance, you can reduce unnecessary acceleration and braking, which will improve MPG. This is especially true for city driving in your XJL.
