Former Mercedes motorsport boss Norbert Haug believes "Formula 1 would be a great fit" for Porsche as the German manufacturer ponders a possible future involvement.
Following its departure from the prime LMP1 category of World Endurance Championship, and it commitment to Formula E from 2019, Porsche has expressed an interest in returning to Grand Prix racing.
The manufacturer insists its current potential prospects only include an involvement as an engine manufacturer beyond 2020, when F1 introduces its new engine platform.
But rumors of a buy-out of Red Bull Racing by Porsche have also gathered pace lately. In any case, Norberg Haug, who oversaw Mercedes' very successful relationship with McLaren, believes Porsche and F1 are a perfect fit.
"I can imagine that very well and from my point of view Formula 1 would be a great fit for Porsche," Haug, told Speed Week.
"Like Audi, they can either spend EUR 250 million in prototypes or join Mercedes with a far more cost-effective move in Formula 1.
"If successful, the international media and audience exposure is unequalled," he added.
"Porsche did an incredible job with its LMP1 prototype, had an excellent engine and car concept, and therefore demonstrated its competence for a commitment in Formula 1."
