25 MPG combined won’t win any hypermiling awards, but for the 2025 BMW 750e xDrive Sedan, that figure represents a balancing act. It’s the compromise buyers are prepared to make for a vehicle that delivers both strong performance and a plug-in hybrid’s capacity for near-quiet, electric-only cruising. These are buyers who value effortless power and cutting-edge technology as much as they appreciate lower fuel costs, and for them, the 750e’s fuel economy makes sense.

City and highway performance

The EPA estimates the 750e achieves 24 MPG in the city and 27 MPG on the highway. This split reflects the nature of the turbocharged engine with electric motor. The 3.0-liter inline-six turbo engine, coupled with an electric motor and BMW’s xDrive all-wheel drive system, is optimized for a blend of efficiency and power. The electric motor can handle shorter city commutes with zero emissions. The gas engine kicks in for longer highway stretches, contributing to a respectable, if not groundbreaking, MPG figure for a large luxury sedan with this level of performance.

Expect the highway number to dip if you regularly exploit the 750e’s acceleration.

Annual fuel cost

The EPA estimates that you’ll spend approximately $2,300 per year on fuel for the 2025 BMW 750e xDrive Sedan. This calculation is based on driving 15,000 miles annually, using a blend of city and highway driving, and factoring in national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the price of gasoline in your area, and how often you use the plug-in hybrid’s electric-only range. The ability to significantly reduce that $2,300 figure with diligent home charging is a key advantage.

Real-world expectations

The EPA provides a standardized benchmark, and real-world MPG will fluctuate. Regular charging and using the electric motor for shorter trips will dramatically increase your miles per gallon, potentially pushing it well beyond the EPA’s 25 MPG combined estimate. Aggressive driving, sustained high speeds, and neglecting to plug in the vehicle will conversely decrease your MPG, bringing it closer to that of a traditional gasoline-powered large sedan. Consider the weight of the all-wheel drive system and the compromises of a plug-in hybrid. Be sure to use all BMW fuel economy data to benchmark your experience.

How it compares

The 750e xDrive’s fuel economy places it in a competitive, but not class-leading, position. The Mercedes-Benz S580e plug-in hybrid achieves a slightly higher 26 MPG combined. The all-electric Mercedes-Benz EQS Sedan bypasses fuel economy concerns altogether, offering a pure electric driving experience. The Lexus LS 500h hybrid, rated at 25 MPG combined, matches the 750e but lacks the plug-in capability. For many 750e buyers, the comparison isn’t solely about MPG. It’s about the driving experience, the prestige of the BMW badge, and the technology offered. The MPG differences are often secondary.

Even within the BMW lineup, you can discover 750E MPG across all years to see how the vehicle’s fuel economy has changed over time.

Tips to maximize efficiency

Consistent charging is key to maximizing the efficiency of the 750e’s plug-in hybrid system. Develop a routine of plugging in your vehicle whenever it’s parked at home or at work to maintain a full battery and maximize electric-only driving range. This will substantially reduce your reliance on the gasoline engine and lower your overall fuel consumption.

Use the BMW’s driving modes. The “Electric” mode prioritizes electric-only driving, ideal for short commutes and city errands. The “Hybrid” mode optimizes the powertrain for efficiency and performance, while the “Sport” mode unleashes the full power of the engine and electric motor, sacrificing fuel economy. Choose the appropriate mode based on your driving conditions and needs.

Anticipate traffic flow and practice smooth driving techniques. Avoid sudden acceleration and braking, maintain a consistent speed, and use regenerative braking whenever possible to recapture energy and recharge the battery. These adjustments can make a difference in your fuel efficiency.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly check your tire pressure and inflate them to the recommended levels, which can be found on the driver’s side doorjamb or in your owner’s manual.
