Say what you will about their design department, but BMW is known for producing some of the most amazing engines on the market. Especially the Bavarian automaker's stoic M division, whose current V10 engine has won its fair share of awards and then some. The same goes for the S54B32, Bimmer's internal code-name for the 3.2-liter iron-block straight-six which the company is now preparing to retire after seven years in production.

Over its lifetime, the 3.2 provided motivation for such performance icons as the E46 M3, the Z3-based M roadster and breadvan, and the Z4 M, as well as the exotic Wiesmann MF3. But with a new Z4 on its way, S54B32 is being sent to pasture, replaced now in various applications by Bimmer's highly-rated twin-turbo 3.0-liter inline-six. The latter is a a fantastic engine, but there will always be a special place in our hearts for the cast-iron 3.2.
