The first-generation Porsche Boxster (the 986) was introduced in late 1996; it was powered by a 2.5-litre flat six-cylinder engine. The design was heavily influenced by the 1992 Boxster Concept. In 2000, the base model was upgraded to a 2.7-litre engine and the new Porsche Boxster S variant was introduced with a 3.2-litre engine. In 2003, styling and engine output was upgraded on both variants. The 986 generation was replaced by the Porsche Boxster of the 987 generation in 2005.
