22 MPG combined isn’t going to win any fuel-sipping contests, but it’s a figure that fits the expectations of people shopping for a flagship luxury sedan like the 2022 BMW 745e xDrive. This isn’t a car bought for its frugality; it’s a statement of success, a mobile office crafted for the executive who prioritizes comfort, technology, and a dash of sporting character. The plug-in hybrid powertrain, with its ability to quietly glide around town on electric power alone, is more about refinement and reduced emissions in urban environments than outright gas savings.

City and highway performance

The EPA estimates the 2022 BMW 745e xDrive achieves 19 MPG in the city and 26 MPG on the highway. The city figure reflects the potential benefits of the plug-in hybrid system, as regenerative braking and electric-only driving can noticeably reduce fuel consumption in stop-and-go traffic. The highway number, while respectable, shows that a large, all-wheel-drive sedan with a turbocharged six-cylinder engine requires energy to maintain speed. These figures are not class-leading, but they represent a reasonable compromise between performance and efficiency for a vehicle of this type.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 BMW 745e xDrive at $2,650. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate, and your actual fuel costs may vary depending on your driving habits, local fuel prices, and the amount of time you spend driving on electric power. Drivers who frequently plug in their 745e and take advantage of its electric range will likely see significantly lower annual fuel costs than those who primarily rely on the gasoline engine.

Real-world expectations

While EPA estimates provide a useful baseline, real-world fuel economy often deviates. 745e owners who diligently charge their vehicles and primarily use them for shorter commutes can expect to see MPG figures that are significantly higher than the EPA combined rating. But those who frequently undertake long highway journeys without plugging in will likely see MPG closer to the EPA highway rating, or even slightly lower if maintaining high speeds. Factors like driving style, tire pressure, and ambient temperature also play a role. The 745E MPG across all years shows a clear trend: using plug-in charging is key to reaching optimal numbers.

How it compares

The 2022 BMW 745e xDrive faces competition from other plug-in hybrid luxury sedans. The Mercedes-Benz S580e, while not strictly comparable due to its more powerful engine, offers similar comfort and technology with a focus on fuel economy. Its plug-in capabilities can yield impressive results in the right driving conditions. Looking at all Bmw fuel economy data, one could also cross-shop with BMW’s own X5 xDrive45e, which delivers similar electric range in a more practical, albeit less opulent, package. Meanwhile, non-hybrid competitors like the Genesis G90 with its twin-turbo V6 offer similar levels of luxury but without the potential for electric driving. The G90 typically achieves around 20 MPG combined. The plug-in hybrid capability is where the 745e appeals to this kind of buyer.

Tips to maximize efficiency

The most effective way to improve the 745e’s fuel economy is to fully use its plug-in hybrid system. Regularly charging the battery allows you to drive on electric power as much as possible, especially for short trips around town. Make it a habit to plug in whenever the car is parked at home or at work, even if the battery isn’t completely depleted.

Use the car’s driving modes to your advantage. The “Electric” mode prioritizes electric-only driving, while “Hybrid” mode intelligently balances electric and gasoline power for optimal efficiency. Experiment with these modes to find the settings that best suit your driving style and the type of roads you’re driving on.

Gentle acceleration and braking can significantly improve fuel economy. Avoid aggressive starts and stops, and anticipate traffic flow to maintain a steady speed. Regenerative braking, which recharges the battery when you decelerate, is most effective when you brake smoothly and gradually.

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

Minimize unnecessary weight in the vehicle. Carrying extra cargo adds weight, which increases fuel consumption. Remove any items from the trunk or back seat that you don’t need to carry on a regular basis.
