2008 Porsche Cayman

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 Cayman.

Body PASSENGER CARTransmission Automatic 5-spd

Classified as a passenger car, the 2008 Porsche Cayman pairs a 5-spd automatic transmission with EPA fuel economy figures of 19 city, 26 highway, and 21 combined mpg. Positioning this model year within the broader 2007-2024 complaint history reveals that the 2008 Cayman predates both the lineup's lowest complaint year of 2012—which saw only a single grievance—and its highest peak of seven complaints in 2014. Consequently, the 2008 model represents an early, baseline era for the vehicle's reliability, sitting well before the most troubled year in its history and offering researchers a look at the nameplate before its later fluctuations.
