Despite the gains in engine output and highway fuel economy, Porsche-philes were in an uproar when the mid-engine Cayman (and Boxster) turned away from the stalwart flat-six engines in favor of two new turbocharged flat-fours in 2017. Even the Cayman GTS came with one. The only way to get a naturally aspirated six-cylinder Cayman was with the pricey Cayman GT4. The GT4 was and is widely praised for its track-focused demeanor and trick bits—but also has diminished livability and limited availability. Add to that a modicum of conspiracy theorizing that Porsche wouldn’t allow any Cayman to outperform its halo car, the 911 Carrera. The theory went that the GT4’s “artificially” lower engine output, manual-only transmission (then), and too-tall gears were how Porsche hid the true potential of the Cayman. It came close but never did make the numbers of a base 911.
With the recent addition of the benchmark PDK dual-clutch automated manual, that performance delta has flipped the other way with the Cayman GT4 slightly ahead of a current base Carrera (but still trailing the Carrera S). Still, the Cayman GT4, boasting some suspension components from the even more racy 911 GT3, remains a track-oriented car with resulting tire noise roar and a busy ride on the street.
