Audi's next TT could be based on the Porsche 718

Recently, spy photos have shown that Audi's next-generation TT may be based on the Porsche 718. These two prototypes belong to Audi, not Porsche, with license plates "IN" and both are newly registered. If these prototypes are indeed camouflaged test cars for the next-generation Audi TT, then choosing the Porsche 718 as the basis is a wise choice.
