Ever-stringent government fuel economy and CO2 emissions standards forced Porsche to downsize and turbocharge its entire range of engines. This meant that the marketing department leaned on the flat-four heritage of the 550 Spyder and 718 race cars, dubbing the internally-designated 982 Boxster and Cayman models as the 718. The MA2-based flat-fours of the base and S versions of the Cayman had more varied specifications than any of their predecessors. The 2.0-liter MA2/20 of the base model had a turbocharger with a conventional internal wastegate for boost control, while the 2.5-liter, 350-hp MA2/22 of the Cayman S had a variable turbine geometry turbocharger in addition to a conventional internal wastegate to reduce exhaust backpressure.
