22 MPG combined won’t win the 2020 BMW 745e xDrive any fuel economy awards, but it’s an acceptable figure for a plug-in hybrid luxury sedan that accelerates quickly and provides a comfortable interior. This car is for a specific buyer: one who wants quiet comfort, advanced technology, and the BMW badge, but also wants the *idea* of lower fuel costs and less gas, even if the effect is small. They’re not buying this car to save money on gas; they’re buying it because it fits their self-image.

City and highway performance

The EPA estimates the 2020 BMW 745e xDrive will get 19 MPG in the city and 26 MPG on the highway. These figures show how the hybrid powertrain improves fuel efficiency in stop-and-go city driving compared to gasoline-powered models. The electric motor assists the gasoline engine during acceleration and allows limited all-electric driving, reducing fuel consumption on short trips. Highway MPG is lower, because the gasoline engine does more of the work at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 BMW 745e xDrive at $2,650. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway, using national average fuel prices. This is a useful benchmark, but driving habits and local fuel costs change how much you spend on fuel each year. This figure does *not* account for savings from charging the vehicle at home or at public chargers.

Real-world expectations

The 745e’s real-world MPG depends on driving style and charging habits. Charging often and maximizing electric-only range improves fuel economy. Drivers who mainly use the 745e for short trips and always plug in can expect MPG figures better than the EPA estimates. Those who rarely charge the battery and mostly use the gasoline engine will likely get fuel economy like a non-hybrid large sedan. Driving fast will hurt fuel economy, negating the hybrid system’s benefits. As always, your mileage may vary.

How it compares

The 745e is efficient compared to other luxury sedans. The non-hybrid BMW 750i xDrive gets just 17 MPG combined. The Mercedes-Benz S560 gets 19 MPG combined. Even the smaller Mercedes-Benz E450 sedan gets only 24 MPG combined. The Lexus ES 300h hybrid is more efficient at 44 MPG combined, but it’s for a different buyer. Someone considering a 745e isn’t looking for ultimate fuel efficiency; they’re choosing between luxury sedans with some electric capability. For that customer, the official EPA combined figure could potentially be improved.

Tips to maximize efficiency

Take advantage of the 745e’s electric features. Plug in often, even for short periods. The more you use electric power, the less gasoline you’ll use, improving your fuel economy and reducing your carbon footprint. Learn the car’s driving modes. Selecting “Electric” mode will prioritize electric driving, while “Hybrid” mode balances electric and gasoline power for efficiency depending on driving conditions.

Accelerate smoothly and gradually. Hard acceleration burns more fuel, regardless of the vehicle. A gentler touch on the accelerator pedal allows the electric motor to do more of the work, reducing the need for the gasoline engine to turn on. Anticipate traffic flow and maintain a consistent speed. Avoid unnecessary braking and sudden acceleration.

Use the BMW Connected app. This allows you to monitor the car’s charging status and preconditioning. Preconditioning the cabin remotely while the car is plugged in uses grid power instead of battery power, extending your electric range. The app also provides insights into your driving habits and offers tips for improving fuel efficiency.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly check your tire pressure and inflate them to the recommended levels on the door jamb sticker. This simple maintenance item can noticeably impact your 745E MPG across all years. Remember to consult all Bmw fuel economy data.
