Ross Brawn believes the so-called B-team model should be preserved in Formula 1, arguing it helps new and smaller teams to compete.

This model, where teams source much of their parts from other teams, has been heavily criticised by Renault principal Cyril Abiteboul, while Haas boss Guenther Steiner, who’s team have such a relationship with Ferrari, and Toro Rosso chief Franz Tost who have a similar partnership with Red Bull, have defended the model.

Now, Brawn has weighed in on the debate, arguing that the ‘B-team’ system should not be eliminated from the sport as part of Liberty Media’s 2021 vision, rather tweaked to give it a future which the most of the grid can accept.
