23 MPG combined isn’t going to win any hypermiling competitions, but for the 2020 BMW 740i xDrive, it’s a practical reality accepted by owners who prioritize effortless power and all-weather confidence over squeezing every last mile from a gallon of premium fuel. This isn’t a car bought for its frugality; it’s a statement of success, a mobile office, and a supremely comfortable long-distance cruiser where the smooth surge of the inline-six and the surefootedness of xDrive are important.
City and highway performance
The EPA estimates suggest 20 MPG in the city and 28 MPG on the highway. While these numbers provide a baseline, remember that the 740i’s turbocharged engine is sensitive to driving style. A heavy foot on city streets will drastically reduce the 20 MPG figure, while a steady hand on long highway journeys, using cruise control and anticipating traffic, can potentially nudge that 28 MPG number higher. The eight-speed automatic transmission is key to optimizing fuel economy, smoothly selecting the correct gear to keep the engine in its most efficient range. However, its sport programming also encourages more aggressive downshifts and higher revs when drivers demand quicker acceleration, which will hurt efficiency. Understanding the transmission’s nuances is critical to optimizing mileage.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2020 BMW 740i xDrive at $2,500. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average price for premium fuel as determined by the EPA’s calculations. Your actual fuel costs could vary depending on how much you drive, how you drive, and what fuel prices are in your area. If you primarily drive in the city or have a lead foot, expect to spend considerably more. Conversely, if you mostly cruise on the highway and drive conservatively, you might save some money. Essentially, this $2,500 estimate offers an average benchmark; your mileage may vary.
Real-world expectations
Owners of the 2020 BMW 740i xDrive often report real-world fuel economy that closely mirrors, or sometimes slightly exceeds, the EPA estimates, especially on longer journeys. The key is understanding the car’s character. It’s a luxury sedan designed for comfort and performance, not less gas. Engaging the “Eco Pro” driving mode can help improve fuel economy by optimizing throttle response, transmission shift points, and HVAC settings. However, expect a noticeable reduction in performance. The trade-off might be worthwhile on long, monotonous highway drives, but most drivers will likely prefer the more responsive modes for everyday use.
How it compares
Compared to its competitors, the 2020 BMW 740i xDrive’s fuel economy is generally within the expected range for its class. The Mercedes-Benz S450 4MATIC, for example, achieves a similar 22 MPG combined. The Audi A8 offers comparable figures. However, some competitors, like the Lexus LS 500h hybrid, offer significantly better fuel economy, achieving around 25 MPG combined. The decision often comes down to priorities. The Lexus prioritizes fuel efficiency with its hybrid powertrain, while the BMW emphasizes driving dynamics and a more traditional luxury experience. Those seeking all all Bmw fuel economy data in one place can find options to compare different vehicles. For those specifically trying to understand its impact on other years, 740I MPG across all years are available.
Tips to maximize efficiency
Take advantage of the “Eco Pro” driving mode, especially on long highway drives. This mode adjusts the car’s systems to prioritize fuel efficiency, softening throttle response and optimizing gear changes. While it might not be ideal for spirited driving, it can noticeably improve your mileage during steady-state cruising.
Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel economy. Consult the sticker on the driver’s side door jamb for the recommended tire pressure and ensure your tires are properly inflated. Even a few PSI difference can impact fuel consumption.
Avoid aggressive acceleration and braking. The 740i xDrive’s turbocharged engine delivers ample power, but sudden bursts of speed and hard braking waste fuel. Smooth and consistent driving maximizes efficiency. Anticipate traffic flow and maintain a steady speed whenever possible.
Minimize idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you’re stopped for more than a minute, turn off the engine. Modern BMWs are equipped with start/stop technology, which automatically shuts off the engine at stoplights to save fuel, although you can disable it if preferred.
Consider the weight you’re carrying. Remove unnecessary items from the trunk. Extra weight reduces fuel economy. While this might seem insignificant, every pound adds up, particularly in a luxury sedan like the 740i xDrive.
