01 · Überblick

The invention of a genre

Unveiled at the 1984 Geneva Motor Show, the first M5 established the genre of the super sedan: the M88/3 from the M1 with 286 PS, hand-built at Motorsport GmbH — externally almost indistinguishable from a 528i. This very inconspicuousness became its trademark.

For catalytic converter markets, the S38B35 with 260 PS ran in parallel. With approximately 2,200 units, the E28 M5 is the rarest production M5 — and the foundation for everything that came after.

Einordnung

  1. 1984 Premiere in Geneva — the M1 engine moves into the sedan.

Matching numbers and history are everything. M88 maintenance (valve clearance, chain) at a specialist; bodywork: wheel arches, spring mounts.

Die Konkurrenz

Mercedes 500 E didn't arrive until 1990

In 1984 the M5 simply had no rival — it invented the segment.
