The 2024 BMW 740i Sedan’s 28 MPG combined rating shows a restraint alongside luxury, an acceptable trade-off for buyers who prioritize a quiet and technologically advanced driving experience over outright efficiency. It’s a statement, and the fuel consumption reflects the power and prestige.

City and highway performance

The EPA estimates for the 740i Sedan are 25 MPG in the city and 31 MPG on the highway. These numbers illustrate a predictable trend: the 3.0L inline-six cylinder engine, equipped with BMW’s TwinPower Turbo technology, uses more fuel in stop-and-go conditions. The highway figure demonstrates the engine’s efficiency when able to stretch its legs at consistent speeds. The smooth-shifting 8-speed automatic transmission (S8) plays a key role, keeping the engine in its optimal rev range for both power delivery and fuel conservation. Drivers who frequently navigate congested urban environments will likely see numbers closer to the city estimate, while those who spend more time on open roads can reasonably expect to achieve or even slightly exceed the highway figure. Take a look at 740I MPG across all years.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 BMW 740i is $2,050. This figure is calculated based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel expenses may vary depending on your driving habits, the type of fuel you use, and local fuel prices. For example, using premium fuel (which is recommended for optimal performance) will increase your annual fuel cost. The $2,050 figure provides a standardized benchmark for comparing the 740i’s fuel consumption to other vehicles in its class.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Aggressive driving, frequent short trips, and extreme weather conditions can negatively impact fuel efficiency. Those who prioritize smooth acceleration, maintain consistent speeds, and avoid unnecessary idling may find themselves exceeding the EPA estimates. The “break-in” period for a new vehicle can sometimes result in slightly lower fuel economy initially. As the engine components settle in with mileage, efficiency often improves.

How it compares

In the realm of full-size luxury sedans, the 2024 BMW 740i’s fuel economy is competitive, but not class-leading. The Mercedes-Benz S500 4MATIC, for example, achieves a similar 26 MPG combined, prioritizing power and features. Vehicles like the Lexus LS 500 manage a slightly better 29 MPG combined, but are seen as less driver-focused. Buyers in this segment generally accept a certain level of fuel consumption in exchange for the performance, comfort, and technology they desire, making the 740i’s MPG a calculated compromise many are willing to make.

Tips to maximize efficiency

One of the simplest ways to improve fuel economy in the 740i is to adopt a smoother driving style. Avoid aggressive acceleration and braking, as these habits consume significantly more fuel. Anticipate traffic flow and maintain a consistent speed whenever possible.

Ensure that your tires are properly inflated. Under-inflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels, which can be found on a sticker inside the driver’s side doorjamb.

Minimize the use of energy-intensive accessories, such as air conditioning. While climate control is a necessity in many situations, using it sparingly can make a noticeable difference. Consider using the fan or opening the windows when appropriate, especially at lower speeds.

Take advantage of the 740i’s driving modes. The “Eco Pro” mode optimizes various vehicle settings to maximize fuel efficiency. While it may slightly reduce performance, it can be a useful tool for long highway journeys where efficiency is important. The adaptive cruise control can also play a part, maintaining consistent, efficient speeds. Give your engine a short time to warm up for better fuel combustion.
