Haas F1 team boss Guenther Steiner has added his name to the list of those against introducing a third car into some Formula 1 teams.

The idea, first put forward by Mercedes motorsport boss Toto Wolff as a way to promote young drivers, has been struck down by Red Bull boss Christian Horner and FIA race director Charlie Whiting who doubted whether the smaller outfits could ever agree.

Now, Steiner has seemingly backed up his notion by voicing his concerns, believing it would have a negative impact on the championship and the fans.

"It could confuse the whole picture," he argued. "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."

Certainly, the Italian confirmed, Haas would not be a team able to even consider the option of adding a third car to their line-up.

"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," he said.

"Until that happens, there is no thinking about a third car for us."
