34 MPG combined might surprise some when discussing a BMW, but the 2018 328d xDrive isn’t a typical Bimmer. It’s a diesel-powered sedan designed to deliver the renowned BMW driving experience with efficient performance. This makes it a good option for those who prioritize lower fuel costs without sacrificing the brand’s signature performance.

City and highway performance

The EPA estimates for the 2018 BMW 328d xDrive show a detailed picture of its fuel efficiency. In the city, it gets 30 MPG, a respectable figure for a luxury sedan equipped with all-wheel drive. This shows the engine’s ability to handle stop-and-go traffic without excessive fuel consumption. On the open road, the 328d xDrive excels, with an impressive 40 MPG highway rating, a fantastic choice for long commutes or road trips. Its strong fuel economy results in fewer stops at the pump and more enjoyable driving.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,650 for the 2018 BMW 328d xDrive. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of driving you do, and fuel prices in your area. The $1,650 figure gives a useful benchmark for comparing the 328d xDrive’s fuel costs to other vehicles. It’s important for prospective buyers to consider this in light of their own driving and fuel price expectations.

Real-world expectations

While the EPA estimates provide a standardized measure of fuel economy, real-world driving conditions can significantly affect the numbers you achieve. The 328d’s diesel engine performs best when fully warmed up, so shorter trips in cold weather may result in lower MPG figures. However, consistent highway driving at moderate speeds should allow you to meet or exceed the EPA’s 40 MPG highway estimate. Factors like driving style, tire pressure, and vehicle maintenance also play a role.

How it compares

The 2018 BMW 328d xDrive’s fuel economy is favorable compared to its competitors. For example, the gasoline-powered BMW 330i xDrive from the same year achieves only 27 MPG combined. The Mercedes-Benz C300 4Matic, another popular luxury sedan, gets 26 MPG combined. Even some hybrid competitors, like the Lexus ES 300h (44 MPG combined), target a different buyer than the 328d driver who appreciates both fuel efficiency and BMW’s sporty driving dynamics, something the Lexus does not offer. For buyers seeking both luxury car refinement and excellent fuel mileage, the diesel-powered 328d provides strong value because of its fuel efficiency and BMW performance.

Tips to maximize efficiency

Gentle acceleration and smooth braking maximize fuel economy in the 328d xDrive. Avoid aggressive driving habits such as hard acceleration and sudden stops, since these can significantly reduce your MPG. Anticipate traffic flow and maintain a consistent speed whenever possible.

Regular maintenance is critical for fuel efficiency. Keep your tires properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce MPG. Ensure that your engine is properly tuned and that all scheduled maintenance is performed on time, including oil changes and filter replacements.

Reduce unnecessary cargo and weight in your vehicle; the heavier your vehicle, the more fuel it consumes. Remove any items that you don’t need daily, such as extra tools, sporting equipment, or other heavy objects. A lighter vehicle requires less energy to move, improving fuel economy.

Use the 328d’s Eco Pro driving mode, if equipped. This mode optimizes vehicle settings to prioritize fuel efficiency by adjusting throttle response and shifting patterns. While it may slightly reduce performance, it can help you achieve fuel savings, especially during city driving.
