The 2019 BMW X4 xDrive30i’s 25 MPG combined fuel economy won’t break any records, but it’s good enough for what it is: a stylish crossover with a coupe roofline that values driving and brand appeal over pure efficiency. The X4 buyer is likely more interested in the elevated driving position of an SUV, the security of all-wheel drive, and the sporty BMW image. Fuel economy is a secondary concern.
City and highway performance
EPA estimates are 22 MPG in the city and 29 MPG on the highway. The city number is realistic for stop-and-go traffic conditions. The highway figure is attainable on long trips if you drive carefully. The X4 xDrive30i’s turbocharged 2.0-liter four-cylinder engine, working with its smooth eight-speed automatic transmission (S8), provides enough power for merging and passing. Aggressive acceleration, especially in the city, will lower the city MPG. The engine responds well, but it uses more gas when pushed hard. The X4 performs best on the highway because of its well-designed drivetrain and relatively aerodynamic shape when compared to other similar crossovers.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2019 BMW X4 xDrive30i at $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that premium fuel is recommended for the best performance, a detail which is already considered in the annual estimate of fuel cost. Your actual cost will vary based on driving habits and local fuel prices.
Real-world expectations
The EPA provides a standard for comparison, but real-world fuel economy varies. Don’t always expect to get 29 MPG on the highway, especially if you speed or drive in heavy traffic. The 22 MPG city number can also drop if you idle a lot or accelerate quickly during your commute. Sport mode will hurt fuel consumption. A smooth driving style and avoiding unnecessary idling will help you get closer to the EPA estimates.
How it compares
The X4’s fuel economy is competitive in its class. The Acura RDX gets a slightly lower 24 MPG combined, and the Mercedes-Benz GLC 300 Coupe gets about the same, 25 MPG. The all-electric BMW iX is much more efficient, but it costs more and needs charging. For more information, check out all Bmw fuel economy data. The X4’s numbers are similar to its competitors. Before buying, decide if you value the X4’s styling and driving more than saving on gas in a compact crossover. Review X4 MPG across all years before deciding.
Tips to maximize efficiency
Whenever possible, use Eco Pro mode. This changes the engine and transmission for the best efficiency, reducing throttle response and optimizing when the car shifts gears. It might feel less sporty, but it saves fuel, especially in the city.
Check your tire pressure regularly. Underinflated tires increase rolling resistance, which wastes gas. Check the sticker on your driver’s side doorjamb for the correct pressure.
Remove extra weight from the vehicle. The more the vehicle weighs, the more fuel it uses. Remove unneeded items from the trunk and back seats to improve efficiency.
Avoid idling. Idling wastes fuel. If you’ll be stopped for more than a minute or two, turn off the engine. The X4’s start/stop system helps, but watch out for battery drain in very hot or cold weather.
Plan your trips efficiently. Combine errands to reduce cold starts. Cold starts use more fuel because the engine needs to warm up. Careful route planning helps you avoid traffic, which lowers fuel economy.
