“We now know the (Le Mans) regulations for 2020,” said Enzinger.
“In the next weeks Peugeot should decide whether they come or not. But even if they do, we have to consider whether we want to go another two or three years in Le Mans.
“At the moment, I cannot assess that.”
Auto Bild also claim that Ezinger and fellow chief Andreas Seidl will also head to the Austrian Grand Prix for talks.
In addition, McLaren’s Zak Brown and Eric Boullier were both present at Le Mans, sparking further speculation that they are interested in a customer engine deal with Porsche.
Formula 1 is not the only option Porsche are considering, with Formula E acting as another alternative.
