Porsche has been testing for quite some time now the new GT4 version of the 718 Cayman. And it appears that there will be more six-cylinder models coming to the mid-engine Boxster and Cayman range.
Other than the upcoming track-focused GT4, Porsche might be installing the same 4.0-liter flat-six unit from the 911 GT3 into “Touring” versions of the Spyder and GT4 models respectively.
Porsche has worked hard and managed to make the naturally aspirated flat-six compliant with the latest Euro 6d emission regulations without sacrificing power. Reports have suggested that the Cayman GT4 and Boxster Spyder will put out around 425bhp while the Touring models will get it with around 380bhp.
