323i

323i is a BMW model designation used on several variants of the 3 Series, identifying cars equipped with a 2.3- to 2.5-liter inline-six engine. The exact specifications and availability of the 323i varied by generation and market, and the badge was used intermittently from the late 1970s through the 1990s. Across its appearances, the 323i generally sat between the entry-level 320i and the higher-performance 325i/328i in the lineup.

In the late 1970s and early 1980s, the 323i appeared on the then-new 3 Series as a higher-performance alternative to the 320i, using a 2.3-liter inline-six and offering increased driveability and equipment. In later generations, particularly in markets outside the United States, BMW used the 323i badge on 3 Series cars powered by around 2.3 to 2.5 liters of displacement, often with a tuned version of the standard six-cylinder engine and standard or optional performance features. Power outputs typically ranged roughly from the mid-140s to about 190 horsepower, depending on generation and market.

Today, the 323i badge is largely historical in most regions, as BMW standardized its naming conventions around 325i/328i/330i and higher-performance M variants. The 3 Series lineage continues to be defined by a broad range of engines and trims rather than a single 323i specification.
