The 2017 BMW 750i gets 20 MPG combined. No one dropping six figures on a flagship luxury sedan is expecting Prius-like efficiency. This car makes a statement; it’s a technological marvel and a comfortable rocket ship all in one. The 4.4L twin-turbo V8 is the key component; good fuel economy is simply the price of admission for the effortless power it provides.

City and highway performance

The EPA estimates 17 MPG in the city and 26 MPG on the highway. The city figure is realistically achievable if you’re careful with the accelerator. However, the 750i’s strong torque and refined eight-speed automatic transmission make fast acceleration almost addictive, and frequent bursts of speed will quickly lower that number. On the open road, 26 MPG is a reasonable target, especially if using cruise control and resisting the urge to use the engine’s ample passing power. Long highway cruises are exactly what the 750i is designed for. It will deliver them in supreme comfort, with a respectable MPG figure when driven carefully.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW 750i at $2,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and fuel prices in your area. If you spend most of your time in stop-and-go traffic or drive fast regularly, expect to exceed this estimate. Those who primarily use the 750i for long highway journeys may find their annual fuel bill to be somewhat lower.

Real-world expectations

While the EPA provides valuable benchmarks, real-world fuel economy will likely differ. The 750i is a heavy car, full of technology and luxurious features. This weight, combined with the temptation to use the V8’s power, makes matching the EPA figures consistently difficult. Expect somewhere in the 16-22 MPG range in mixed driving. If fuel economy is an important concern, explore alternatives within the BMW lineup. You can access all Bmw fuel economy data on this site.

How it compares

The 2017 Mercedes-Benz S550, a direct competitor to the 750i, achieves a virtually identical 20 MPG combined. The Lexus LS 460, while known for its reliability, lags behind at 19 MPG combined. Audi’s A8 with its 4.0 TFSI engine also gets 22 mpg combined. While these differences may seem marginal, they become relevant when considering the total cost of ownership. These other models offer different tradeoffs between luxury, performance, and efficiency. Exploring 750I MPG across all years can help paint a more detailed image of the vehicle’s overall value.

Tips to maximize efficiency

The simplest way to improve fuel economy is smooth and consistent acceleration. Avoid abrupt starts and stops. The 750i’s ample torque means you don’t need to floor it to accelerate reasonably. Gentle pressure on the accelerator pedal will suffice in most situations, allowing the engine to operate more efficiently.

Take advantage of the 750i’s driving modes. Selecting “Eco Pro” mode will remap the throttle response, adjust the transmission shift points, and potentially reduce the energy consumption of auxiliary systems. This mode is particularly effective for highway driving or navigating stop-and-go traffic where aggressive acceleration is unnecessary.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Check your tire pressure regularly and inflate them to the recommended levels specified on the doorjamb sticker. Additionally, ensure that your tires are properly aligned. Misalignment can cause excessive wear and tear and increased fuel consumption.

Minimize idling. Letting the engine idle for extended periods wastes fuel. If you’re stopped for more than a minute, switch off the engine. The 750i’s starting system provides quick restarts, making it easy to avoid unnecessary idling. Use the auto stop/start feature carefully.

Service the vehicle regularly by adhering to the factory-recommended maintenance schedule. This includes changing the engine oil, air filter, and spark plugs at the prescribed intervals. A well-maintained engine operates more efficiently and delivers optimal fuel economy.
