Since 2017, following the demise of the Manor squad, Formula 1 has had 20 cars on its grid. Questions exist over whether this number needs to rise. For instance, does the championship need new teams simply because that's too small a grid and it should be 22 or 24 cars? Or should Liberty Media be preparing the ground for a new entrant to come in should any of the current competitors drop out?
Those questions have now been given extra focus by confirmation that at least one new F1 team project is being worked on in the background.
French-backed Panthera Team Asia F1 has recruited former Super Aguri, Caterham and Manor engineer Tim Milne as its head of aerodynamics, and since January he's been working on the venture with a small group in a design office at Silverstone.
