23 MPG combined isn’t going to win any awards in 2019, but the BMW 740i xDrive isn’t competing for top honors in fuel efficiency. For a large, all-wheel-drive luxury sedan packing a turbocharged inline-six, it’s a figure that most buyers will happily accept as the price of admission. The 740i xDrive doesn’t skimp on comfort, technology, or driving engagement, and those priorities usually outweigh squeezing every last mile from a gallon of premium fuel. Its target demographic prizes effortless power and all-weather security over hybrid badges and hypermiling techniques. It is a vehicle designed for executives, entrepreneurs, and those who simply appreciate the finer things in life while demanding practicality, a blend that naturally involves certain compromises.

City and highway performance

The EPA estimates the 2019 BMW 740i xDrive at 20 MPG in the city and 29 MPG on the highway. These figures reflect the engine’s ability to deliver a broad torque curve even at low RPMs, minimizing the need to aggressively dip into the throttle during typical urban driving. On the open road, the eight-speed automatic transmission keeps the engine in its sweet spot, allowing for relaxed cruising and efficient operation. Expect highway mileage to decrease if you frequently engage the sportier driving modes and exploit the engine’s full potential, but even then, the 740i xDrive manages commendable efficiency for its class.

Annual fuel cost

The EPA calculates that the annual fuel cost for the 2019 BMW 740i xDrive will be approximately $2,500. This estimate is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that the 740i xDrive requires premium gasoline, which typically costs more than regular unleaded. Your individual fuel costs could vary based on your driving habits, local fuel prices, and the amount of city versus highway driving you do.

If you primarily drive short distances in congested urban environments, your annual fuel expenses will likely exceed the EPA’s estimate. For those spending more time on open highways, the final cost may be slightly lower.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy often deviates. Drivers who consistently use the 740i xDrive’s performance capabilities or spend most of their time in stop-and-go traffic will likely see numbers closer to the low end of the EPA range. Conversely, those who prioritize smooth acceleration, maintain consistent speeds on the highway, and use the car’s Eco Pro mode could achieve figures closer to or even slightly exceeding the EPA’s estimates. The xDrive all-wheel-drive system, while beneficial for traction, also subtly impacts fuel consumption compared to rear-wheel-drive models.

How it compares

Compared to its peers, the 2019 BMW 740i xDrive lands in the middle of the pack. The Mercedes-Benz S450 4Matic, boasting similar performance and all-wheel drive, achieves nearly identical EPA figures. The Lexus LS 500 AWD posts figures similar to to the BMW. The Audi A8 also posts similar figures. The discrepancies, while potentially meaningful to some buyers, often become secondary considerations when evaluating luxury sedans that prioritize performance, comfort, and technology over maximizing MPG. For those seeking better economy, all of all Bmw fuel economy data includes plug-in hybrid options that offer more efficient stop-and-go performance.

Tips to maximize efficiency

One of the simplest ways to improve fuel economy in the 740i xDrive is to use the Eco Pro driving mode. This mode adjusts throttle response, transmission programming, and climate control settings to optimize fuel efficiency. While it may slightly reduce the car’s responsiveness, it can make a tangible difference in fuel consumption, particularly during city driving.

Gentle acceleration and smooth braking are critical for maximizing MPG in any vehicle, especially one with a powerful engine like the 740i xDrive. Avoid abrupt starts and anticipate traffic flow to minimize unnecessary braking. The car’s regenerative braking system assists in capturing energy during deceleration, but this system is not a substitute for smooth, anticipatory driving.

Proper tire inflation also plays a significant role in fuel efficiency. Ensure that your tires are inflated to the recommended pressure, which can be found on the driver’s side doorjamb or in the owner’s manual. Underinflated tires increase rolling resistance, forcing the engine to work harder and consequently consuming more fuel.

Reduce unnecessary weight in the vehicle. Carrying around excessive cargo or rarely used items in the trunk adds extra weight, which negatively impacts fuel economy. Periodically declutter the car to minimize the load on the engine. While this will not be a massive change, it will subtly improve the 740I MPG across all years.

Finally, regular maintenance is essential for optimal fuel efficiency. Ensure that the engine is properly tuned, air filters are clean, and oil changes are performed according to the manufacturer’s recommendations. A well-maintained engine operates more efficiently, translating to better fuel economy and overall vehicle performance.
