The E36 represented a dramatic leap forward for the 3-Series, with its more aerodynamic design and sophisticated multilink rear suspension. While European customers enjoyed a full range of engine options from frugal four-cylinders to potent inline-sixes, U.S. buyers initially only received six-cylinder models. The disparity was most noticeable with the M3. European M3s boasted a sophisticated 3.0L (later 3.2L) inline-6, while U.S. models made do with a less powerful 3.0L engine derived from the 325i. This difference in specification would remain a point of contention among American BMW enthusiasts for years to come.
