On the 960, I'm disappointed that they won't build one, but what market position would it occupy?

Presumably it would have been a mid-engined twin of the next generation Huracan and R8 (provided they continue to make the R8).  So it would be priced in between R8 and Huracan, in a price segment that already includes several top tier 911 models, whether GTx cars or Turbo cars.  And what powerplant would it have?  Surely not the Audi V10.  Either a turbo flat six or turbo V8 from Panamera/Cayenne.

So what would Porsche do about the 911s in the same segment?  Would the 960 be a more luxurious GT car than the 911?  In that case, build a front-engined car, a two door Panamera.  If the 960 were a hardcore track special sports car, who would buy an RS, whether GT3 or GT2?  Or what if the customer base shunned the 960 and bought the RS 911 instead?  The GT2 RS is one of the quickest road cars in the world around a track; how could they make something materially faster?

Alternatively, what if they tried to position the 960 as a Superfast / Aventador competitor (a market segment that is not as crowded); a Porsche based off of an Audi would be a tough sell against an Italian V12 even if the Porsche could do the Nordschleife in 5 minutes in reverse.

Bottom line - why go to the effort to develop a generic supercar that is nonessential to the brand's model line and competes directly with the most aspirational 911 models?
