The 2016 BMW X3 xDrive35i’s 21 MPG combined won’t win any fuel-sipping contests, but that’s hardly the point. This is a performance-oriented compact SUV, not a hybrid, and its mission is to deliver utility alongside driving pleasure. The typical xDrive35i buyer isn’t primarily striving for maximum fuel efficiency; they want the smooth power of the turbocharged inline-six and the grip of all-wheel drive, even if it uses more gas.

City and highway performance

The EPA estimates this X3 at 19 MPG in the city and 26 MPG on the highway. The city estimate reflects stop-and-go traffic, where the X3’s 3.0L engine will inevitably consume more fuel. The highway number is better, showing the engine’s ability to cruise efficiently once up to speed. This is helped by the smooth-shifting eight-speed automatic transmission (S8), which keeps the engine in its optimal range. Even with all-wheel drive, highway miles will be economical.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW X3 xDrive35i at $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. This number will change depending on driving habits and local gas prices, but it’s a useful comparison point. Buyers of this model should be aware of this cost, and budget accordingly. If high fuel cost is a concern, check X3 MPG across all years to find a more efficient version.

Real-world expectations

While the EPA provides a standardized estimate, real-world MPG in the X3 xDrive35i will vary depending on driving style, road conditions, and maintenance. Aggressive driving and frequent use of the engine’s power will hurt fuel economy. Gentle acceleration and consistent highway speeds will improve it. Regular maintenance, like tire inflation and oil changes, can also lead to better fuel efficiency. Prioritizing fuel economy may result in numbers closer to the EPA estimates; those who enjoy the X3’s performance may see lower figures.

How it compares

Compared to other compact luxury SUVs of the time, the X3 xDrive35i’s fuel economy isn’t the best. For example, the 2016 Acura RDX with all-wheel drive gets around 22 MPG combined. The Audi Q5 2.0T Quattro, with its turbocharged four-cylinder, gets slightly better fuel economy at around 23 MPG combined, although with less horsepower. Even a naturally-aspirated six-cylinder like the Lexus RX 350 achieves around 22 MPG combined in front-wheel-drive configuration. However, these alternatives don’t necessarily offer the same performance or driving experience as the X3 xDrive35i. A buyer must consider their individual needs and priorities. Looking at all Bmw fuel economy data can help give a snapshot of how their priorities align with their potential fuel costs.

Tips to maximize efficiency

Take it easy on the accelerator. The turbocharged engine is responsive, so you don’t need to push the pedal heavily to accelerate. Gentle acceleration will help you use less fuel, especially in city driving.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which lowers fuel economy. Check the sticker on the driver’s side doorjamb for the recommended tire pressure and check your tires regularly.

Reduce unnecessary weight. Extra cargo adds weight, reducing fuel efficiency. Remove unnecessary items from the trunk or cargo area to improve your MPG.

Minimize idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a minute or two, it’s more efficient to turn off the engine.

Use cruise control on the highway. Cruise control maintains a consistent speed, which can improve fuel economy on long highway drives. Avoid using cruise control in hilly terrain, the vehicle may downshift frequently, which uses more fuel.
