About the 2017 Porsche Cayman S

The 718 Cayman S marked Porsche's controversial shift from naturally aspirated flat-sixes to turbocharged flat-fours, trading the iconic wail for improved torque delivery. Michael Mauer's design evolution refined the 981's proportions while the 2.5-liter turbo four produces 350 hp and 309 lb-ft, delivering genuine mid-engine dynamics that many argue surpass the 911's rear-engine layout. The six-speed manual remains the purist's choice, though PDK offers quicker shifts. While enthusiasts initially mourned the loss of the flat-six soundtrack, the S has proven itself as a serious driver's tool with razor-sharp handling and impressive performance. Early examples are becoming increasingly sought after as collectors recognize this generation's significance in Porsche's electrification transition.
