STANDARD transmission in the Boxster S is a six-speed manual. The optional automatic is a five-speed, utilising Tiptronic manual override and incorporating an "intelligent" function. The system is able to detect gradients and will refrain from the "hunting" up and down through ratios to which many autos are prone. For example it will hold a lower gear on throttle lift-off, or change down appropriately with an application of the brakes. The automatic transmission has five programmes or shift maps, which are selected depending on driving style.
