Many sites are posting this information based off a rumor but considering Porsche already put this motor into multiple 718 Chassis' themselves it is an easy rumor to bank on. Odds are we will see both a 718 Cayman GT4 and Boxster Spyder with a 3.8 liter detuned GT3 flat-6 derivative.


If the rumor is correct both manual and PDK transmissions will be available as options with the manual debuting first.

Thinner glass ala the Carrera T will help shed weight and apparently knocking off 110 pounds is the goal.

The 420 horsepower should be artificially limited by software meaning there will be quite a bit to extract from the powerplant making for a Cayman and Boxster we can finally say is not neutered.

More info to come as the actual debut dates near.
