Fuel economy at a glance
These are the EPA's official ratings for the 2017 BMW 328d. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.
Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).
| Combined MPG | 36 MPG |
| City MPG | 31 MPG |
| Highway MPG | 43 MPG |
| Annual fuel cost | $2,250 |
| Tailpipe CO₂ | 285 g/mi |
| Fuel type | Diesel |
How the 2017 BMW 328d compares
The 2017 BMW 328d returns 36 combined MPG. Cars in the Compact Cars class for the same model year average 27.7 MPG, which puts this car ahead of the class average by about 30%.
The most efficient car in the Compact Cars class for the 2017 model year is the Volkswagen e-Golf at 119 MPG. The bar chart below puts the BMW 328d alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 2017 model year (across all classes) returns 26 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2017 model year is on its own page.
Annual fuel cost across driving patterns
The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for diesel, which is $5.40/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.
The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 416.7 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $1,125 |
| Average driver, 15,000 miles per year | $2,250 |
| Heavy driver, 25,000 miles per year | $3,750 |

Specifications
The 2017 BMW 328d runs a 2-liter 4-cylinder turbocharged engine paired with a automatic (s8), sending power through rear-wheel drive.
Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
