According to Giancarlo Minardi – founder of the team now known as Scuderia Toro Rosso – BMW engineers have been conspicuously spotted lately at F1 test sessions and grands prix, lending to speculation that the new engine regulations may entice the Bavarian automaker back into the series. According to Minardi, BMW's marketing division is pushing for the automaker's return to F1, with the board slated to make a decision in May. BMW would be more likely to consider an engine-supply deal rather than taking a team over like it had with Sauber, but with which team or teams it might collaborate remains a big question mark at this point.
As if that's not enough, Ford is said to be considering taking over Cosworth's aborted V6 turbo engine program to take both outfits back into the sport as well. Cosworth supplied F1 engines under the Ford banner for years, but returned under its own name for four seasons from 2010 through 2013 before shuttering its program to develop an engine to meet the new regulations adopted this season.
With Honda, BMW and Ford back on the grid, F1 would be back up to six engine suppliers like it had been in the 2008 season that marked the highest level of participation from automakers in decades.
