The keyword phrase functions grammatically as a proper noun. It operates as a specific, unique name for a particular entity, project, or product model rather than a general class of objects. As the main point of an article, this grammatical function dictates that the subject is a singular, identifiable thing to be described and analyzed.
This determination is based on the composite nature of the term. "911" serves as the base noun, identifying the specific Porsche model. The "x" acts as a conjunction indicating a collaboration, crossover, or thematic variant. "Wild Hunter G2" is a specific designator, with "G2" likely signifying "Generation 2." When combined, these elements do not describe a quality (adjective) or an action (verb) but form a single, unified title for a specific custom automotive build.
Consequently, an article using this term as its main point would be inherently expository, focused on defining and detailing the subject. The core content would revolve around the characteristics, history, and specifications of this particular vehicle or project. The grammatical classification as a proper noun establishes the article's purpose: to inform the reader about this distinct entity.
