McLaren have talked with the Volkswagen Group, whose Audi and Porsche brands have been linked to future Formula One entry, but nothing has been agreed, according to team boss Zak Brown.
German newspaper F.A.Z. has reported that Volkswagen's supervisory board will decide at the end of February whether both Audi and luxury brand Porsche would enter the sport.
Sources told Reuters at the end of last year that a possible partnership between Audi and McLaren was on the table, but undecided.
"I am hearing they (Volkswagen) are going to do something with Red Bull on the Porsche front," Brown told reporters at the McLaren factory.
