34 MPG combined from the 2017 BMW 328d xDrive shows efficiency without giving up the driving experience of a BMW, especially for those who want all-wheel drive and diesel torque in a compact executive sedan.

City and highway performance

The EPA estimates the 2017 BMW 328d xDrive gets 30 MPG in the city and 40 MPG on the highway. The city figure is good, given urban driving conditions, but the highway figure is where this car excels. It’s built for consistent speeds, where the efficient turbodiesel engine operates best. Drivers with longer commutes or road trips will benefit most from this great fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW 328d xDrive at $1,650. This assumes 15,000 miles per year and average national fuel prices. Your actual fuel expenses will change based on your driving, fuel type, and local prices. However, $1,650 is a good guide for budgeting.

Real-world expectations

EPA estimates are a baseline, but real-world fuel economy changes with driving styles, roads, and weather. Hard acceleration, braking, and idling will hurt fuel efficiency. Gentle acceleration, anticipating traffic, and steady speed can help you meet or beat the EPA estimates. Tire pressure, maintenance, and cargo weight also matter. Owners who watch these things may see the best fuel economy from their 328d xDrive. Check out real user submissions for 328D MPG across all years to see performance reported by actual owners.

How it compares

The 2017 BMW 328d xDrive compares well in fuel economy. The gasoline-powered BMW 330i xDrive from the same year gets about 28 MPG combined. The Audi A4 Quattro gets around 27 MPG combined. A Mercedes-Benz C300d (if available then) would be similar. 328d xDrive owners cared about fuel economy, so even 1 or 2 MPG matters.

Tips to maximize efficiency

Use the BMW’s Eco Pro mode. This setting changes engine performance and throttle to improve fuel efficiency. It also adjusts climate control to save energy, helping you get more miles per gallon of diesel.

Check your tire pressure often. Low tires increase rolling resistance, making the engine work harder and burn more fuel. The correct tire pressure, on a sticker inside the driver’s door, improves fuel economy and extends tire life.

Avoid idling. If stopped for over a minute, turn off the engine. Modern engines restart fast, and restarting uses less fuel than idling. This matters in cities with many stops.

Use cruise control on the highway. Consistent speed improves fuel economy by limiting acceleration and deceleration. Cruise control on long trips can noticeably improve MPG.

Service the vehicle on schedule. Regular maintenance, like oil changes, air filter changes, and fuel filter changes, helps engine performance and fuel efficiency. A maintained engine runs better, saving fuel and extending your BMW 328d xDrive’s life.
