The E28 was the first 5 Series produced with diesel engines (the 524d and 524td models) and with a petrol model specifically aimed at increased fuel economy (525e/528e model).

The four models available at the launch of the E28 were the 518, 520i, 525i and 528i. With the 518 using a straight-four petrol engine and the other three models using a straight-six petrol engine. Over the course of the E28 model, the following models were added: the 524d and 524td using diesel engines, the 518i (a fuel-injected version of the 518), the 525e/528e as fuel-economy models, and the upper-specification 533i, 535i, M535i, and M5 models.

A liquid petroleum gas (LPG) option was introduced for some petrol engines in 1984.
