E34 Introduction:
Introduced globally in 1987 as a successor to the E28, the E34 represented a more aerodynamic, larger, and technologically advanced chassis. The 535i was a key performance model within the E34 lineup.
E34 Facelift:
A significant facelift occurred in late 1991 (for model year 1992), featuring updated bumpers, side moldings, mirrors, wheels, and interior refinements. The 535i (M30 engine) was largely phased out in North America after 1993 in favor of the M60 V8 engines (540i) and later the M52 inline-6 (525i, 528i), though the M30 continued in some global markets for a short period.
Production Years 535I E34:
1987–1993 (global production period for the M30-powered 535i variant).
Manufacturing Locations:
