BMW introduced the 430i nameplate for the 2017 model year as part of the 4 Series update, replacing the earlier 428i designation on the coupe, convertible, and Gran Coupe. The change was tied to BMW’s newer turbocharged four-cylinder engine naming convention, so 430i became the badge for the brand’s mainstream four-cylinder 4 Series models rather than a separate standalone car line.
In the first production period, the 430i sat below the six-cylinder 440i and above entry-level four-cylinder variants in markets where those were offered. It quickly became the volume version of the 4 Series range, appealing to buyers who wanted the style and rear-drive-based character of the 4 Series without moving into the higher-performance M Performance models. The nameplate appeared across multiple body styles, which helped establish it as the familiar core engine grade within the 4 Series family.
When BMW launched the second-generation 4 Series for the 2021 model year, the 430i badge carried over rather than being retired, continuing the same basic role in the lineup. Today, BMW still offers 430i versions of the 4 Series Coupe, Convertible, and Gran Coupe, so the nameplate remains in active production. For that reason, the final model year is not set here.
Enthusiasts often view the 430i as the balanced 4 Series choice: not the most powerful version, but a historically important one because it became the standard-bearer for BMW’s modern four-cylinder 4 Series range. Its history is tied to the wider 4 Series identity, making it one of the key badges in the model’s contemporary era.
