What major revisions were made to the European-spec E34 M5 during its production?
Except for minor trim and equipment variations, there were few revisions to the original European-spec E34 M5 during its production. The first major round of changes occurred with the introduction of the more powerful 3.8-liter M5 in late 1991. Along with the larger engine, the 3.8-liter M5 brought Adaptive M Suspension, a reduced-effort clutch and a myriad of cosmetic alterations. Also, the M5 Touring was added at this time.
