24 MPG combined might seem average, but it’s acceptable for the 2017 BMW X3 sDrive28i. This vehicle is often chosen by drivers who prioritize a premium driving experience and the practicality of a compact SUV over maximum fuel efficiency. The X3 offers the dynamic handling and refined interior expected of a BMW, and that involves some trade-offs.

City and highway performance

The EPA estimates for the 2017 X3 sDrive28i are 21 MPG in the city and 28 MPG on the highway. The city MPG reflects the engine’s increased effort in stop-and-go traffic, while the highway number demonstrates its efficiency when cruising. The turbocharged 2.0L four-cylinder engine, powerful enough for most drivers, needs to engage the turbo more frequently in urban environments to maintain momentum, increasing fuel consumption. On the open road, the smooth eight-speed automatic transmission helps the engine settle into an efficient range, maximizing fuel economy during longer trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW X3 sDrive28i at $2,400. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs can change based on your driving habits, local fuel prices, and the type of fuel you use. The X3 doesn’t require premium fuel, but using it can sometimes produce slightly better performance and potentially improve fuel economy, though this may not offset the higher cost.

Real-world expectations

While EPA estimates provide a useful baseline, your actual mileage will vary. Factors like driving style, traffic conditions, and even tire pressure can impact fuel economy. Drivers who accelerate quickly will likely see lower MPG figures, while those who prioritize smooth acceleration and consistent speeds can get closer to the EPA estimates. Also, carrying extra weight in the vehicle will also impact fuel efficiency.

How it compares

The 2017 X3 sDrive28i is in a competitive segment, and its fuel economy should be considered against its rivals. The Acura RDX, with its V6 engine, achieves around 23 MPG combined. The Lexus NX 300h hybrid delivers significantly better fuel economy, around 31 MPG combined. The Audi Q5 achieves similar numbers to the X3, with around 25 MPG combined from its 2.0T engine. For a deeper dive, compare X3 MPG across all years. Potential buyers need to weigh fuel economy against the driving dynamics, luxury features, and brand prestige that each vehicle offers, which is why many choose the X3.

Tips to maximize efficiency

Use the X3’s drive mode selector. Selecting “Eco Pro” mode optimizes the powertrain for maximum fuel efficiency by adjusting throttle response and shift points to favor economy over performance. This mode is especially helpful for highway driving and less demanding city commutes.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly and inflate them to the recommended level. You’ll find the correct pressure listed on a sticker in the driver’s side doorjamb.

Avoid aggressive driving habits. Rapid acceleration and hard braking consume significantly more fuel. Drive smoothly, anticipating traffic flow and maintaining a steady speed when possible. This is particularly crucial in the city, where stop-and-go driving can dramatically reduce fuel economy.

Reduce unnecessary weight inside the vehicle. Extra cargo adds weight, forcing the engine to work harder and consume more fuel. Remove any unnecessary items from the trunk and interior to minimize the load on the engine.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel efficiency on long drives. Be mindful of traffic conditions and disengage cruise control when necessary for safety. See all Bmw fuel economy data to compare relative to other models.
