19 MPG combined isn’t going to win any fuel economy awards, but it’s the reality of driving a 2017 BMW 750i xDrive with its strong 4.4L twin-turbocharged V8. To dwell on that number too much, however, is to misunderstand the mission of this car. This isn’t about eking out every last mile per gallon; it’s about effortless performance wrapped in supreme luxury. The buyer of a 750i xDrive prioritizes power, prestige, and all-weather capability, and accepts, perhaps even barely notices, the fuel consumption that comes with it.
City and highway performance
The EPA estimates suggest 16 MPG in the city and 25 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the 750i’s considerable weight and powerful engine require more fuel to get moving. The highway number, however, is a bit more encouraging, showcasing the engine’s efficiency at cruising speeds, aided by the smooth-shifting 8-speed automatic transmission. In steady-state highway driving, the 750i’s long gearing and advanced engine management system allow it to achieve respectable fuel economy while still having ample power in reserve for effortless passing maneuvers. These figures show how far the xDrive all-wheel-drive system’s efficiency has come.
Annual fuel cost
The EPA estimates an annual fuel cost of $3,050 for the 2017 BMW 750i xDrive. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, local fuel prices, and the type of fuel you use. The 750i’s engine is designed for premium fuel, so you sacrifice performance if trying to save a few cents at the pump. Premium fuel prices are used by the EPA to calculate this annual cost.
Real-world expectations
While the EPA provides a standardized benchmark, real-world fuel economy often deviates. Aggressive driving, frequent short trips, cold weather, and even tire pressure can all influence your MPG. The 750i’s onboard computer provides real-time fuel consumption data, allowing drivers to monitor their efficiency. Given the car’s performance potential and the driving style it encourages, consistently achieving the EPA estimates requires a conscious effort. Owners who frequently exploit the V8’s power and enjoy rapid acceleration should anticipate fuel economy figures closer to the city estimate, or even slightly below.
How it compares
Compared to its competitors, the 2017 750i xDrive’s fuel economy is fairly typical for the segment. The Mercedes-Benz S550 4MATIC, with its 4.7L V8, achieves similar EPA estimates, around 17 MPG city and 26 MPG highway. The Audi A8 4.0T, featuring a 4.0L twin-turbo V8, posts numbers in the same ballpark. Even the Porsche Panamera 4S, known for its performance-oriented character, sits around 18 MPG city and 25 MPG highway. All of these cars are at or around the same overall fuel economy rating. Buyers cross-shopping these vehicles aren’t necessarily prioritizing fuel efficiency above all else; performance, luxury, and brand cachet are often higher on the list. For buyers who are interested in this vehicle, but are looking for the 750I MPG across all years, this may be an important consideration.
Tips to maximize efficiency
Minimize aggressive acceleration. The 750i’s V8 is tempting to unleash at every opportunity, but gentle acceleration and anticipation of traffic flow can significantly improve fuel economy. Use the car’s Eco Pro mode, which adjusts throttle response and transmission shift points to prioritize fuel efficiency. It might slightly dull the driving experience, but it can make a noticeable difference on longer journeys.
Ensure proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and inflate them to the recommended levels, which are typically listed on a sticker inside the driver’s side doorjamb.
Reduce unnecessary weight. Carrying extra weight in the trunk or cabin reduces fuel economy. Remove any items that are not essential for your daily journeys. Those extra golf clubs or that set of emergency supplies sitting in the trunk all add up.
Plan your routes strategically. Avoid congested areas and routes with frequent stops and starts. Using the navigation system to find the most efficient route can save fuel, especially during peak traffic hours. Also know that all Bmw fuel economy data can change year-to-year.
