However, this idea has been rebuffed by plenty of big names in F1 and Haas boss Gunther Steiner is the latest of those to give his opinion.
Steiner said: "I’m not in agreement with a third car because it could confuse the whole picture.”
The Italian believes that fans would be confused with some teams running a third car in a few races a season, especially for fans that are newer to the sport than most.
He continued: "It would be very difficult to understand for the fans and new spectators that sometimes a third car could run.
"It would distort the actual championship, in my opinion. I think we need to sit back and come up with a better idea."
Steiner gave another reason for the idea to be scrapped and that’s the cost of running a third car.
An F1 weekend costs enough already, especially for the smaller teams and it could provide an unfair advantage for some of the bigger teams.
Steiner added: "As it stands, we have no interest to field a third car. If somebody comes up and pays for it, yes we can consider it.
"Until that happens, there is no thinking about a third car for us."
So, even with major changes in F1 scheduled just around the corner, it doesn’t look like three-car teams will be one of those.
