24 MPG combined is not the primary selling point for the 2019 BMW 740i, nor should it be. This is a flagship luxury sedan, a vehicle designed for effortless power, opulent comfort, and advanced technology. Those seeking ultimate fuel efficiency generally aren’t cross-shopping a 7 Series with a Prius. The 740i buyer prioritizes an elevated driving experience and a prestigious image; reasonable fuel economy is a welcome bonus, not a deciding factor.

City and highway performance

The 740i’s EPA estimates break down to 21 MPG in the city and 29 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the 3.0L turbocharged inline-six engine is constantly accelerating the nearly two-ton sedan. Even here, BMW’s engineering shines through; the engine’s responsiveness and the smooth-shifting eight-speed automatic transmission contribute to a relatively efficient experience. Out on the open road, the 740i truly excels. The highway MPG demonstrates the engine’s ability to cruise comfortably at higher speeds, delivering respectable fuel economy thanks to optimized gearing and aerodynamic design. This is where drivers will most appreciate the car’s effortless power delivery and quiet composure, making long journeys a relaxing experience.

Annual fuel cost

According to EPA estimates, the annual fuel cost for the 2019 BMW 740i is approximately $2,400. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price when the estimate was calculated. Individual fuel costs will vary depending on driving habits, local fuel prices, and the type of fuel used. The $2,400 figure provides useful context to compare the 740i’s fuel expenses with other vehicles, but real-world costs will differ.

Real-world expectations

It’s essential to temper expectations based on the EPA estimates with real-world conditions. Aggressive driving, frequent short trips, and extended idling can significantly reduce fuel economy. Conversely, consistent highway driving with a light foot can yield figures closer to, or even exceeding, the 29 MPG highway rating. Factors such as tire pressure, vehicle maintenance, and even the type of gasoline used can influence fuel efficiency. Keep in mind that the 740i is a large, luxurious sedan with a powerful engine; expecting hybrid-like numbers is unrealistic.

How it compares

Within the large luxury sedan segment, the 2019 BMW 740i’s fuel economy is competitive, though not class-leading. The Mercedes-Benz S450, another popular option, achieves similar numbers, around 21 MPG city and 30 MPG highway. The Audi A8 posts similar results but these ratings can fluctuate slightly from year to year. Upgrading to a V8-powered 7 Series model, such as the 750i, will noticeably reduce fuel economy. The Lexus LS 500 lands in that same MPG bracket, too. Those prioritizing fuel efficiency above all else may consider a plug-in hybrid variant, if available, or explore smaller, lighter luxury sedans. Savvy shoppers will compare all Bmw fuel economy data before making a decision. You can also explore 740I MPG across all years.

Tips to maximize efficiency

Use the 740i’s driving modes. The “Eco Pro” mode optimizes various vehicle settings, such as throttle response and shift points, to prioritize fuel conservation. While it may slightly reduce performance, it can make a noticeable difference in fuel consumption, particularly during city driving. Experiment to see if the trade-off is acceptable for your typical commute.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check tire pressure regularly and inflate to the recommended levels specified on the doorjamb sticker. This simple step can improve fuel efficiency and extend tire life.

Avoid aggressive acceleration and braking. The 740i’s potent engine can tempt drivers to accelerate quickly, but this burns extra fuel. Similarly, hard braking wastes energy. Drive smoothly and anticipate traffic flow to minimize unnecessary acceleration and deceleration. Gentle driving habits contribute to improved fuel economy.

Reduce unnecessary weight. Carrying excessive weight in the trunk or passenger compartment can reduce fuel economy. Remove any unnecessary items from the vehicle to lighten the load and improve efficiency. Every pound counts, especially in a large sedan like the 740i.

Minimize idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you anticipate being stationary for more than a minute, turn off the engine. Modern cars do not require a warm-up period before driving, so idling is unnecessary in most situations. Turn the car off instead of idling.
