Formula One has multiple inquiries from potential team owners who have taken a more behind-the-scenes approach than Michael Andretti, who has been “quite vocal” in his desire to expand the current grid, F1's CEO said Wednesday.

Andretti has petitioned to expand the current F1 grid to 22 cars to accommodate Andretti Global, which he's billing as a true American team. Andretti has taken that route after attempts to purchase an existing F1 team fell apart late last year.
