The 2025 BMW 740i gets 28 MPG combined, which is respectable, especially considering its focus on providing a comfortable and technologically advanced driving experience. It’s not just a frugal choice, it’s a statement of success and a desire for refined performance. The 740i caters to executives and individuals who prioritize luxury, space, and advanced technology, but also appreciate efficiency that isn’t overtly wasteful.

City and highway performance

The EPA estimates the 740i’s fuel economy at 25 MPG in the city and 31 MPG on the highway. These numbers reflect the characteristics of the 3.0L inline-six engine and the smooth eight-speed automatic transmission. The city figure is reasonable for a vehicle of this size and weight, given the frequent starts and stops. On the open road, the 740i’s aerodynamic design and efficient engine allow it to achieve its best fuel economy, making long-distance cruises relatively economical, at least by flagship luxury sedan standards.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW 740i is $2,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. The $2,050 estimate provides a useful benchmark for comparing the 740i’s fuel costs to those of other vehicles. This calculation, also, assumes regular gasoline with an octane rating of 87, but BMW recommends premium fuel for optimal performance.

Real-world expectations

EPA estimates offer a standardized comparison, but real-world fuel economy often differs. Driving style plays a big part, with aggressive acceleration and frequent hard braking significantly reducing MPG. Traffic, weather, and even tire pressure can impact fuel consumption. Expect the 740I MPG across all years to vary, but driving smoothly and maintaining optimal tire pressure can help you achieve figures closer to the EPA estimates. Drivers who frequently engage the Sport driving mode, which encourages more aggressive throttle response and higher RPMs, will likely see lower average fuel economy.

How it compares

The Mercedes-Benz S500 4MATIC, a direct competitor, achieves a similar 28 MPG combined with its 3.0L inline-six engine. The S500’s city rating is slightly lower at 24 MPG, highlighting the differences in how powertrains perform in specific driving conditions. The Lexus LS 500, with its 3.4L twin-turbo V6, manages only 21 MPG combined, making it a less efficient option, which is why many consumers check all Bmw fuel economy data before committing to this class. These comparisons are important for buyers weighing performance against efficiency.

Tips to maximize efficiency

The 740i’s Driving Dynamics Control offers various driving modes, including Eco Pro. Selecting this mode optimizes engine settings, transmission behavior, and even climate control to prioritize fuel efficiency. Using Eco Pro in less demanding driving situations can noticeably improve your MPG, especially in urban environments.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Regularly checking and maintaining optimal tire pressure is a simple way to improve fuel economy.

Minimize unnecessary weight. Carrying extra cargo can reduce fuel efficiency. Remove any items you don’t need to lighten the load and improve MPG, especially if most of your driving is in the city.

Anticipate traffic flow and avoid aggressive driving. Smooth acceleration, gradual braking, and maintaining a consistent speed can dramatically improve fuel economy. By anticipating traffic lights and maintaining a safe following distance, you can minimize the need for sudden stops and starts, which are inefficient.

Use cruise control on the highway to maintain a consistent speed and improve fuel efficiency. This feature helps prevent unintentional acceleration and deceleration, contributing to better fuel economy during long-distance driving.
