f25

F25 is a designation used in several industries to label products, models, or project identifiers. It is not tied to a single standard, so its meaning varies by context and by the company that uses it.

The most widely recognized use in the automotive sector is BMW's internal chassis code for the second-generation X3, produced from 2010 to 2017. The X3 designated as F25 reflects BMW’s generation-specific naming convention, and the model introduced a redesigned platform, updated powertrains, and enhanced technology relative to the earlier generation.

Beyond automotive uses, the F25 code appears as a product or project identifier in other industries, including aerospace, electronics, and rail systems, among others. These uses are independent of the BMW designation, and there is no universal meaning attached to the code. Consequently, determining what F25 refers to in a given context requires supporting information such as the industry, manufacturer, and time period.
