The Porsche Boxster is a mid-engined two-seater roadster. The first-generation Boxster (the 986) was introduced in late 1996; it was powered by a 2.5-litre flat six-cylinder engine. In 2000, the base model was upgraded to a 2.7-litre engine and the new Boxster S variant was introduced with a 3.2-litre engine. In 2003, styling and engine output was upgraded on both variants. In 2005, Porsche debuted the second generation of Boxster, the type 987, with a more powerful engine and styling inspired by the Carrera GT. Engine output increased in 2007, when both Boxster models received the engines from their corresponding Porsche Cayman variants. In 2009, the Boxster models received several new cosmetic and mechanical upgrades, further increasing engine output and performance. The third generation Boxster (type 981) was launched at the 2012 Geneva Motor Show. The fourth (type 982) was launched in 2016 and the marketing name was changed to Porsche 718.
