I think the GT4 engine choice reflects a much larger issue with the overall 718 concept as a 4 cylinder.  I don't know about worldwide, but here in South Florida a new 718 of any flavor is a rare bird.  The S models are essentially $100K cars and as 4 cylinder, regardless of HP, are a hard sell.  A GT4 in any 6 cylinder guise amplifies the shortcoming of the 718 gambit and cast at least some doubt on the initial claims by Porsche that a turbo flat six could not be fit into the boxster/cayman platform. Porsche is at something of a crossroads with the GT4 because unless there is a 385HP twin turbo 4 in the GT4 the 718's long term viability immediately comes into question.
