The BMW 5 Series (E28) model – Specs, Chassis

The BMW E28 is the second generation of BMW 5 Series executive cars, which was produced from 1981 to 1988 and replaced the E12 5 Series.

Pre-series production began in April 1981 and the car was introduced in the autumn that year.

The E28 has a self-supporting body that is welded to the body platform.

The passenger cell is a safety passenger cell with deformation elements both in the front and rear of the vehicle.

Unlike its E12 predecessor and E34 successor, the E28 has a rear-hinged bonnet.

The E28 was the first 5 Series produced with diesel engines (the 524d and 524td models) and with a petrol engined 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.
