24 MPG combined is a reasonable figure for a large, luxurious sedan like the 2016 BMW 740i. No one buys a 7 Series expecting Prius-like fuel efficiency. Efficiency is a consideration, sure, but it plays second fiddle to attributes like comfort, performance, technology, and sheer road presence. The 740i buyer wants a refined driving experience and a cabin that cossets them in luxury, and they’re willing to accept mid-20s fuel economy as the price of admission.

City and highway performance

The EPA estimates 21 MPG in the city and 29 MPG on the highway for the 2016 740i. The city figure reflects the stop-and-go driving conditions that will inevitably reduce efficiency, even with BMW’s efforts to optimize the 3.0-liter turbocharged inline-six engine and eight-speed automatic transmission. The highway MPG shows the engine’s ability to cruise efficiently at steady speeds, making the 740i a comfortable and relatively economical long-distance tourer. Intelligent driving modes and engine start/stop functionality contribute to these figures in different driving scenarios. The automatic transmission’s eight gears certainly contribute to the engine’s efficiency; at highway speeds, the engine can run at very low RPM, reducing fuel consumption.

Annual fuel cost

The EPA estimates annual fuel costs for the 2016 BMW 740i at $2,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind this is just an estimate, and individual fuel costs will vary widely based on driving habits, local fuel prices, and the type of fuel used (premium gasoline is recommended for optimal performance). For drivers who primarily use the 740i for shorter commutes and typically drive less than 15,000 miles per year, the actual fuel cost may be lower.

Conversely, drivers who frequently take long road trips or live in areas with high fuel prices could see annual fuel costs exceed this estimate.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Factors like driving style, traffic conditions, and even tire pressure can impact your MPG. A lead-footed driver who enjoys using the 740i’s 320 horsepower will likely see numbers below the EPA estimates. However, a careful and patient driver who anticipates traffic and avoids hard acceleration might achieve results that meet or even exceed the EPA’s 29 MPG highway rating. The 740i’s driving modes can also play a role; switching to “Eco Pro” mode prioritizes fuel efficiency by adjusting throttle response and transmission behavior. Keep in mind that winter driving, with its cold temperatures and increased use of accessories like heated seats, will negatively impact fuel economy.

How it compares

The 2016 BMW 740i’s fuel economy positions it competitively within the large luxury sedan segment. The Mercedes-Benz S550, with its larger V8 engine, is rated at 17 MPG city and 26 MPG highway. The Audi A8 3.0T managed similar figures to the 740i, achieving 19/29, while the Lexus LS 460 lags slightly behind at 16 MPG city and 24 MPG highway. These differences matter. Buyers cross-shopping vehicles in this class pay attention to details, but the decision rarely comes down to fuel efficiency alone.

A potential buyer might accept slightly lower MPG from the Mercedes-Benz for its air suspension or higher horsepower, or accept this Bmw’s fuel economy over a Jaguar XJ because they appreciate its refined engine.

Tips to maximize efficiency

One of the easiest ways to improve fuel economy in the 740i is to drive smoothly. Avoid hard acceleration and braking, and try to maintain a consistent speed. The engine start/stop system helps save fuel while idling in traffic. However, you can manually disable it with a button on the center console if you find it intrusive and are willing to sacrifice some fuel efficiency for smoother operation in stop-and-go conditions.

Proper tire inflation is another simple but often overlooked factor. Check your tires regularly and inflate them to the pressure recommended on the door jamb sticker. Underinflated tires increase rolling resistance, which negatively affects fuel economy.

Minimize the use of accessories like air conditioning and heated seats when possible. These features place an extra load on the engine, which consumes more fuel. When you need these features, use them judiciously and avoid running them at full blast unnecessarily.

Regular maintenance is crucial for optimal fuel efficiency. Keep the engine properly tuned, change the oil according to the manufacturer’s recommendations, and replace air filters regularly. A well-maintained engine runs more efficiently and helps maximize MPG. Use FuelEconomyHub.com to find all 740I MPG across all years.
