Porsche is working on the much anticipated new Cayman GT4, which is set to further distance itself from its 718 siblings, as it’s expected to use a naturally aspirated six-cylinder engine.

As we have reported before, the powerplant is expected to be the same 4.0-liter unit found in the 911 GT3. However, and in order to keep the necessary distances between the two models, the 493hp engine will be detuned slightly.

It was Andreas Preuninger, Porsche’s GT car division boss, that has previously said that their models will retain a naturally aspirated engine as long as possible, ensuring they offer the right throttle response, the high-revving character and the sound that customers want.

The video from NM2255 shows a test car stretching its legs at the iconic Monza circuit, giving us a first taste of what’s hiding behind the front seats. The six-cylinder soundtrack will please most fans that criticized Porsche’s decision to give their smallest two-seater models four-cylinder turbos to play with.

The crisp gearchanges also betray the PDK transmission fitted in the test car, with Porsche expected to offer an additional manual option to diehard purists.

The new Porsche Cayman GT4 will be accompanied by the similarly hardcore Boxster Spyder, with both models to be lightened and feature some of the tricks seen in the 911 GT3. We don’t know when Porsche is going to reveal their new hardcore mid-engine performer but recent reports suggest that a debut will take place later this year.
