E28

E28 is the chassis code for BMW's second generation of the 5 Series, produced from 1981 to 1988. It succeeded the E12 and was followed by the E34. The E28 introduced a more aerodynamic, modern design for the 5 Series and broadened the range with improved interior refinement and new electronic features for the period.

The lineup offered inline-six engines ranging from mid-sized displacements to more powerful variants. The E28 also spawned the first M5, a high-performance variant developed by BMW M GmbH, which emphasized power, handling, and braking.

The M5 variant launched in 1985 used a high-output engine and suspension tuning, along with unique body trim and interior equipment. It established the blueprint for future M5 models and remains highly regarded among enthusiasts.

Production ended in 1988, making way for the E34. The E28 is considered a milestone in BMW's history, blending everyday usability with high-speed performance. Outside automotive contexts, the designation E28 is also used for a European route in the international E-road network.
