21 MPG combined isn’t going to win any awards, but it’s also not why anyone buys a 2019 BMW 750i with the 4.4L V8. This car represents the pinnacle of BMW luxury and performance, a showcase of engineering designed to cosset its occupants in opulent comfort while delivering effortless acceleration. Fuel economy is secondary to these objectives for the buyer.

City and highway performance

The EPA estimates of 18 MPG in the city and 26 MPG on the highway reflect the realities of driving a powerful, large sedan. In urban environments, the twin-turbocharged V8’s considerable heft and eagerness to accelerate from stoplights will inevitably take their toll. The eight-speed automatic transmission, while smooth and responsive, can’t fully compensate for the engine’s thirst when constantly modulating speed in traffic. Out on the open road, however, the 750i fares better.

Its long gearing and advanced engine management system allow it to cruise relatively efficiently at highway speeds, making those long-distance journeys more palatable.

Annual fuel cost

According to EPA estimates, the 2019 BMW 750i 4.4L V8 will cost you approximately $2,750 per year in fuel. This figure is based on driving 15,000 miles annually and using the national average fuel price for premium gasoline, which is the recommended fuel for optimal performance and longevity of the engine. Keep in mind that actual fuel costs will vary depending on individual driving habits, local fuel prices, and the type of driving done (more city versus highway, aggressive versus gentle).

Those who frequently exploit the engine’s power will likely see this annual cost climb higher.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy can deviate significantly. Drivers with a heavier foot or those who spend more time in congested city traffic can expect to see numbers closer to the city estimate, or even lower. Conversely, those who primarily use the 750i for long highway cruises, and practice hypermiling techniques, may achieve figures closer to, or even slightly above, the EPA highway estimate.

However, it’s safe to assume that most 750i drivers are not overly concerned with maximizing fuel efficiency and will therefore operate within a range somewhat below the EPA combined rating.

How it compares

Compared to other luxury sedans in its class, the 2019 BMW 750i’s fuel economy is fairly typical. The Mercedes-Benz S560, with its 4.0L V8, achieves an EPA-estimated 19 MPG city and 29 MPG highway, placing it slightly ahead on the highway. The Audi A8, equipped with its 3.0L V6, fares significantly better at 19 MPG city and 27 MPG highway due to its smaller engine. And the Lexus LS 500 manages 19 MPG city and 30 MPG highway.

These differences, while notable, likely aren’t dealbreakers for buyers in this segment. They prioritize the driving experience, brand cachet, and advanced features afforded by these flagship vehicles, and they know what to expect in exchange. For all Bmw fuel economy data, see here.

Tips to maximize efficiency

While the 750i owner might not be obsessed with fuel economy, there are still steps one can take to extract more miles from each gallon. Keeping tires properly inflated to the recommended pressure reduces rolling resistance, forcing the engine to work less hard to maintain speed. This single step can make a noticeable improvement, especially on long journeys.

Aggressive acceleration and hard braking are major fuel economy killers. Smooth, deliberate driving allows the engine and transmission to operate more efficiently. Anticipating traffic flow and gradually accelerating or decelerating minimizes wasted energy and contributes to better gas mileage.

Use the driving mode settings. The 750i offers various modes, including “Eco Pro,” which optimizes engine and transmission settings for maximum fuel efficiency. While performance will be slightly reduced, this mode can be beneficial for everyday commuting where outright speed isn’t a necessity.

Reduce unnecessary weight in the vehicle. Excess cargo adds to the vehicle’s overall mass, requiring more energy to move. Removing items you don’t need will lighten the load and improve fuel efficiency, particularly in city driving. A trunk full of golf clubs that only get used once a month serves only to burn more fuel.

Regular maintenance is also critical. Ensuring the engine is properly tuned and that all filters are clean will help it run at peak efficiency. A well-maintained engine consumes fuel more effectively than one that is neglected. Adhering to the recommended service schedule will not only extend the life of your 750i, but also contribute to better fuel economy.
