27 MPG combined isn’t going to win any green awards, but it’s a respectable figure for the 2023 BMW 740i, a full-size luxury sedan that prioritizes strong power and opulent comfort over using less gas. This isn’t a car designed for hypermilers; it’s for executives, entrepreneurs, and drivers who appreciate a refined driving experience and are willing to allocate a portion of their budget to fuel costs in exchange for its performance and premium features.

City and highway performance

The EPA estimates the 2023 BMW 740i at 25 MPG in the city and 31 MPG on the highway. These numbers reflect the adeptness of the 3.0-liter turbocharged inline-six engine and the smooth-shifting eight-speed automatic transmission (S8). Urban driving, with its stop-and-go nature, will naturally dip below the combined rating, while consistent highway runs can potentially exceed the 31 MPG estimate, especially with careful use of cruise control and a light foot. The engine’s ample torque makes it easy to maintain speed without excessive throttle input, contributing to its reasonable highway fuel economy.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2023 BMW 740i at $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and local fuel prices. Factors such as aggressive acceleration, frequent short trips, and persistent use of Sport mode will increase fuel consumption and raise your annual spending. On the other hand, gentle driving and optimized routes could reduce the cost. Consider this EPA estimate as a benchmark for typical driving.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy will vary. Drivers reporting their experiences on fuel economy tracking websites typically see figures around the stated combined MPG, but individual results fluctuate based on the factors mentioned above. Don’t expect Prius-level efficiency, but achieving figures close to the EPA estimates is certainly possible with conscious driving. The 740i’s turbocharged engine with electric motor and aerodynamic design help, but ultimately, driver behavior is the biggest determinant of fuel consumption.

How it compares

In the realm of full-size luxury sedans, the 2023 BMW 740i holds its own in terms of fuel economy. Compared to the Mercedes-Benz S500 4MATIC, which returns an EPA-estimated 24 MPG combined, the 740i offers a slight edge. The Audi A8, another competitor with a similarly sized engine, achieves around 23 MPG combined. These differences might seem small, but they can add up over the lifespan of the vehicle. Buyers considering vehicles in this class often weigh fuel economy against other factors like performance, features, and brand prestige, and the 740i strikes a reasonable balance. For all Bmw fuel economy data, one can see how the 740i fits into the brand offerings. Prospective buyers should also check 740I MPG across all years to see long term trends.

Tips to maximize efficiency

Avoid aggressive acceleration. The 740i’s turbocharged engine delivers ample power, so there’s no need to stomp on the gas pedal to get up to speed. Gradual acceleration conserves fuel and reduces emissions, especially in city driving. Anticipate traffic flow and maintain a steady pace to minimize the need for abrupt braking and acceleration.

Use the car’s driving modes wisely. The 740i offers different driving modes, including an “Eco Pro” mode that optimizes fuel efficiency by adjusting throttle response, transmission mapping, and climate control settings. Using this mode during highway cruising and in stop-and-go traffic can significantly improve fuel economy.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel efficiency. Check your tire pressure regularly and maintain the recommended levels, which can be found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Properly inflated tires also improve handling and extend tire life.

Minimize idling. Excessive idling consumes fuel and emits pollutants. If you’re stopped for more than a minute, turn off the engine. Modern engine start-stop systems, like the one in the 740i, automatically shut off the engine at traffic lights and restart it when you lift your foot off the brake, further reducing fuel consumption in urban environments.
