V18

V18 is a designation used in multiple, largely unrelated fields. It has no single canonical meaning and typically refers to a version number, a model code, or a configuration within a broader system. The precise interpretation depends on the context in which it appears.

In mechanical engineering and automotive history, V18 denotes an eighteen-cylinder piston engine arranged in a V configuration. Such engines have been built for experimental aircraft, marine craft, or industrial applications, but they are relatively uncommon compared with more prevalent V12 or V16 designs. The term conveys a specific cylinder count and layout rather than any particular manufacturer or era.

In software and hardware development, V18 often marks version 18 of a product, platform, or standard. Release notes or documentation associated with V18 typically describe new features, improvements, or bug fixes that distinguish it from prior versions. The label is used across diverse products, including operating systems, development tools, and firmware.

In electronics and electrical engineering, V18 may indicate an 18-volt supply level or a component with a designation that uses the V18 label in schematics. It can also appear as a model or revision code for components, modules, or power-related accessories.

In consumer products and media, V18 can serve as a model number or code within a product line, covering devices such as cameras, appliances, or peripherals. It may also appear in media catalogs or catalogs of spare parts as an identifying tag.

Because the term spans many domains, its precise meaning requires accompanying context, such as the product name, manufacturer, or field of application.
