20 MPG combined isn’t a figure that makes the 2018 BMW 750i stand out. It’s a number that needs context. This isn’t a small, fuel-sipping sedan; it’s a flagship luxury vehicle, with a strong 4.4L V8 engine made to deliver effortless performance and a supremely comfortable driving experience. The 750i appeals to buyers who want power, prestige, and technology over fuel efficiency. They value the smooth power of the V8 and the BMW badge more than saving every last mile from a gallon of premium fuel.

City and highway performance

The EPA estimates that the 2018 BMW 750i gets 17 MPG in city driving and 25 MPG on the highway. The city figure shows the realities of stop-and-go traffic, where the 4.4L V8 constantly overcomes inertia, which hurts fuel consumption. The highway figure is a more optimistic view of what’s possible when the car cruises steadily. The eight-speed automatic transmission (S8) contributes to smooth shifts and refinement and is geared more towards performance than maximizing fuel economy. These numbers are acceptable for the class and are a trade-off for the exceptional power and driving experience this vehicle offers.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 BMW 750i is $2,900. This is based on driving 15,000 miles per year, with a percentage split between city and highway driving, using national average fuel prices for premium unleaded gasoline (which this vehicle requires). It’s important to understand that this is an EPA estimate, and spending will change based on driving habits, local fuel prices, and the actual number of miles driven. Consider this a baseline, but factor in your circumstances for a more realistic projection. The federal government updates the national average fuel prices used in the estimates regularly.

Real-world expectations

While the EPA figures are a standard, real-world fuel economy for the 2018 BMW 750i changes frequently. Aggressive driving, short trips, and extended idling will hurt fuel consumption. Maintaining proper tire inflation and following the recommended maintenance schedule can help improve efficiency. The 750i’s onboard computer provides fuel consumption data, allowing drivers to monitor their driving habits and adjust to improve mileage if they want to. However, it’s rare for 750i owners to focus on saving every tenth of an MPG from this high-performance luxury sedan.

How it compares

The 2018 BMW 750i doesn’t lead its class in fuel economy. The Mercedes-Benz S560, with its 4.0L V8, achieves an EPA-estimated 19 MPG city and 29 MPG highway, a slight edge on the highway. The Audi A8, with its available forced-induction 6-cylinder, can deliver even better fuel economy than the BMW. Even the Porsche Panamera, with its engine options, can provide comparable or slightly better MPG. These comparisons matter because buyers in this segment aren’t only focused on fuel efficiency. They want to know where the 750I MPG across all years fits within the landscape of competing luxury sedans, considering the premium fuel required by these vehicles.

Tips to maximize efficiency

While the 750i prioritizes performance, there are steps you can take to improve its fuel economy. Avoid aggressive acceleration and hard braking. The 4.4L V8 is responsive, but gentle inputs will reduce fuel consumption during city driving and improve your combined MPG.

Use the car’s Driving Dynamics Control system to select “Eco Pro” mode. This mode adjusts engine mapping, throttle response, and transmission shift points to improve fuel efficiency. The reduction in performance is minimal in everyday driving, but the fuel savings can be noticeable.

Ensure that your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, leading to lower fuel economy. Check your tire pressure regularly, especially during temperature changes.

Minimize idling. The 750i’s large engine consumes fuel while idling. If you anticipate being stopped for more than a minute or two, consider turning off the engine if you are in a well-ventilated area and it is safe.

Keep your vehicle properly maintained. Regular oil changes, air filter replacements, and other preventative maintenance can help ensure that your 750i is running at peak efficiency. A well-maintained engine consumes less gas and produces fewer emissions.
