2018 BMW 328d

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 328d.

Transmission Automatic (S8)

The 2018 BMW 328d is the diesel‑powered variant of BMW’s compact executive sedan, built on the same chassis as its gasoline‑engine siblings and equipped with the S8 automatic transmission. Its powertrain delivers a notably efficient 31 mpg city, 43 mpg highway and 36 mpg combined rating, positioning it among the more frugal options in the segment. While the model’s broader complaint record spans 2013‑2015—peaking at 151 reports in 2014 before falling to a low of 27 in 2015—the 2018 iteration benefits from the refinements that followed that dip, suggesting a steadier reliability footing for researchers examining recent model years.
