When the latest Cayman and Boxster adopted the 718 nomenclature, they gave up something in return: their flat-six powertrains. Though Porsche’s sweet six-cylinder lived in on the 718 Cayman GT4 and 718 Boxster Spyder, lesser variants employed an admittedly punchier, though mournfully bland turbocharged four-cylinder. An available manual gearbox and stirring driving dynamics have kept the 718s sharp in their sports car segments, but Porsche purists crave acoustic character.

Now it’s back. With the introduction of the 718 Cayman GTS 4.0, Porsche’s naturally aspirated flat-six returns in a sub-$90,000 middleweight model. With a set of adaptive dampers and more accommodating seats, the Cayman GTS 4.0 appears to be a daily driver’s alternative to the racier Cayman GT4. But is the high-revving boxer-6 enough to convince shoppers to shell out extra coin over competitors like the BMW M2 CS, Audi TT-RS, and Chevy Corvette? Miles shares his thoughts in this in-depth review.
