It remains to be seen if Andretti will be given approval to join the grid as they plan in 2026, but they would have to compete with a customer engine for two years until their power unit supplier, General Motors, will be ready to run its own system in 2028.
Talks are said to have continued between Andretti, GM and F1 CEO Stefano Domenicali during the Miami Grand Prix.
Amid these discussions, a document revealed by RacingNews365 is said to contain an alternative solution to get new teams onto the grid should Andretti’s proposal fail.
The broad idea, fronted by two technical stalwarts Tim Milne and Lewis Butler, would allow for up to three teams to join F1 - but not as a constructor.
In this case, each team would not collect any constructors’ championship points or prize money and compete in a proposed minimum of eight circuits that allow up to 26 cars, whilst operating in a region not currently represented in F1, that being either the Americas, Asia, Africa or Oceania.
Effectively, the teams would be on a three-season trial period, with the view to become a full-time constructor in their fourth racing season.
During these three seasons, they would have to prove that they can expand revenue steams within their home market to a minimum threshold, expand fan engagement, cover prize-fund expansion and compete on track to an acceptable standard.
