The 2017 BMW X3 xDrive28i gets 24 MPG combined, which should be understood in context. This vehicle is not a hybrid and isn’t marketed as an economy car. This compact luxury SUV is designed for buyers who want sporty driving, premium features, and all-weather capability, even if it means slightly lower fuel economy. The X3 is often purchased by urban professionals who require a versatile vehicle for commuting and weekend trips, and for them, the X3’s handling and brand recognition often outweigh concerns about fuel efficiency.

City and highway performance

The EPA estimates for the 2017 X3 xDrive28i provide more detail. In city driving, expect around 21 MPG. This reflects the frequent stops and starts common in urban environments, which reduce engine efficiency. On the highway, the X3 performs better, achieving nearly 28 MPG. This difference shows the gains possible with consistent speeds and less braking, allowing the X3’s smooth eight-speed automatic transmission to select the best gear.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW X3 xDrive28i at $2,400. This is based on driving 15,000 miles per year using national average fuel prices. Keep in mind that this is an estimate. Your actual fuel costs will vary based on your driving habits, the types of roads you drive on, and local fuel prices. Drivers in congested city traffic are likely to spend more, while those who primarily drive on highways might spend less.

Real-world expectations

EPA estimates provide a standard comparison point, but real-world fuel economy can change. The X3’s turbocharged 2.0-liter engine delivers sufficient power efficiently, but it also performs well and makes drivers want to drive fast, especially in Sport mode. Selecting this mode holds gears for longer and sharpens the throttle, increasing performance but also reducing MPG. Similarly, using the xDrive all-wheel-drive system, especially in bad weather, can slightly decrease fuel economy because the system sends power to all four wheels.

How it compares

The 2017 BMW X3 xDrive28i’s fuel economy is average for its class. The Acura RDX, often praised for its value, gets about 23 MPG combined with its V6 engine. The Audi Q5, another German competitor, gets around 25 MPG combined with its 2.0T engine but costs more, and all Bmw fuel economy data can be found on FuelEconomyHub.com. The Lexus NX 300h hybrid is more efficient, offering about 31 MPG combined, but it is less engaging to drive. The X3’s choices reflect what its target buyer wants: performance and luxury are more important, but fuel efficiency still matters. Explore X3 MPG across all years for different models.

Tips to maximize efficiency

One way to improve fuel economy in the 2017 X3 xDrive28i is to drive in Comfort or Eco Pro mode. These settings optimize the engine and transmission for efficiency, using lower RPMs and smoother acceleration. While Sport mode is tempting, only using it sometimes will save fuel.

Proper tire inflation is important. Regularly check your tire pressure, referring to the sticker on the driver’s side doorjamb for the recommended PSI. Under-inflated tires increase rolling resistance, making the engine work harder and using more fuel. Maintaining the correct pressure improves MPG and extends tire life.

Avoid extra weight. The X3 is already fairly heavy, so extra cargo inside or in the trunk puts more strain on the engine. Remove any items you don’t regularly need, and take off roof racks when you’re not using them because they create aerodynamic drag.

Gentle acceleration and braking are key. Avoid quick starts and hard braking, as these use far more fuel than gradual actions. Watch the traffic and maintain a steady speed when possible. The X3’s refined design and engine will reward a gentle touch with better fuel economy.

Consider using cruise control on long highway drives. Maintaining a consistent speed helps optimize fuel consumption, especially on relatively flat roads. Pay attention to hills, however, because cruise control may downshift unnecessarily on inclines, reducing potential fuel savings.
