17 MPG combined. The 2019 BMW X7 xDrive50i is for those who demand a luxurious, supremely comfortable, and relentlessly powerful SUV and who are willing to pay a hefty price, both at the dealership and at the pump, for the privilege. This is transport for families who prioritize space, performance, and a certain level of prestige. They accept the fuel economy as part of the total equation.

City and highway performance

The X7 xDrive50i’s EPA ratings break down to 15 MPG in the city and 21 MPG on the highway. The city number is dismal, reflecting the weight of the vehicle and the demands the driver places on the 4.4L twin-turbo V8 in stop-and-go traffic. Expect frequent fill-ups if your X7 spends most of its time navigating urban landscapes. The highway number is more palatable, although still far from class-leading. A relaxed cruise will yield the best results here, but the temptation to unleash the V8’s power will inevitably lead to lower figures, especially given the X7’s substantial curb weight.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,400 for the 2019 BMW X7 xDrive50i. This figure is based on driving 15,000 miles per year with a mix of city and highway driving and using the national average fuel price. For some X7 owners, that cost might be a rounding error in their budget, but for others, it’s a significant expense that factors into the overall cost of ownership. It’s a figure worth considering and understanding.

Real-world expectations

Don’t expect to consistently achieve the EPA’s numbers. The X7’s V8 is intoxicating, and its effortless torque encourages spirited driving. This, coupled with the considerable weight it has to lug around, means most drivers will likely see real-world fuel economy that falls slightly below the EPA estimates. Driving style has an impact. A heavy foot will decimate fuel economy, potentially dropping MPG into the low teens in city driving. Conversely, adopting a more measured approach and using cruise control on the highway can help to inch closer to the EPA’s 21 MPG.

How it compares

The X7’s fuel economy is not its strong suit when compared to rivals. The Mercedes-Benz GLS 450 4MATIC, with its inline-6 engine, manages a slightly better 20 MPG combined. The Audi Q7, particularly with its 3.0L V6, achieves around 19 MPG combined. Even the Range Rover, another large and luxurious SUV, comes close at 18 MPG combined in its V6 guise. Of course, stepping up to the supercharged V8 Range Rover Sport will yield similar, if not worse, fuel economy than the X7. The difference translates to hundreds of dollars per year in fuel costs. Buyers likely know what they’re getting into, but it’s prudent to consider all Bmw fuel economy data before committing.

Tips to maximize efficiency

Resist the urge to accelerate aggressively. The X7 xDrive50i’s V8 is responsive, but each hard launch comes at the expense of fuel efficiency. Smooth, deliberate acceleration will improve your MPG, especially in urban driving. While the X7 is all about performance, being light on the gas pedal will reward you at the pump.

Use cruise control whenever possible on the highway. Maintaining a consistent speed minimizes unnecessary acceleration and braking, both of which negatively impact fuel economy. Plan your route ahead and anticipate traffic conditions to avoid sudden changes in speed.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended levels specified in the owner’s manual. A small investment in a tire pressure gauge can save you money in the long run.

Minimize unnecessary weight. The X7 is already a heavy vehicle, so avoid carrying unnecessary cargo in the trunk or on the roof rack. Extra weight puts additional strain on the engine, reducing fuel efficiency. Remove any items you don’t need for your journey to improve MPG.

Consider using a fuel additive designed to clean fuel injectors. Over time, fuel injectors can become clogged, leading to reduced fuel efficiency and performance. A quality fuel additive can help to remove deposits and restore optimal injector function, potentially improving MPG by a small margin.
