I don't know, Charlotte. This is one of several posts I've come across here expressing enthusiastic anticipation of a n/a flat-6 powered 718 GT4. Which puzzles me.....
I get that the 981 Cayman GT4 was a truly great car, and a 718 GT4 based on the 4.0 n/a f6 in the 911 GT3 would be a natural evolution of that package. But I for one would find that disappointing....here's why.
In Formula 1 (and other racing series I'm sure) they speak of a particular version of a car as the package
-- meaning the combination of platform
(chassis, steering, brakes, aero, suspension, tires) and engine
. To me, the 718 package is as much defined by the new turbo f4 engines as it is the evolution of the 981 platform. I love the way the whole package works together, but especially how the torquey and efficient turbo power gives this car a unique character and identity unlike the 981 or the 987 I drove for 12 years. It's not just a face-lift next-gen Boxster with enhanced handling and speed -- it's a different package
So as good as a 718 GT4 with 911 GT3 engine might be, it would revert back to the old package of mid-engine Cayman platform with 911 engine. Not a new 718 at all...
But a 718 GT4 with +50hp variant of the current S turbo f4/VTG -- good lord that would be awesome. If Porsche would even allow a non-911 to be faster than the GT3, which I doubt. But whatever power and Nurburgring time Porsche allows a turbo GT4, it would do so much more to raise the image and appreciation of the full 718 package
than giving the haters just what they want -- a relatively large displacement n/a f6 back in the mid-engine platform.
