Wolff: Formula 1 must remain "attractive" after 2021 changes

Toto Wolff says Formula 1 must remain attractive after the 2021 rule and regulation overhaul. He says Liberty Media must get this right. 

"It's important that we get the rules right from 2021 on, and that Formula 1 remains attractive. But the numbers speak for themselves: Formula 1 is our biggest showcase. The advertising and PR value that we generate is enormous and it is increasing. It's a big factor," Wolff told Germany's Sport1. 

Earlier, Gene Haas stated that if the changes cost too much then Haas would leave Formula 1 and Renault's commitment remains unclear. It seems like the current champions will keep Formula 1 as their main priority despite their latest venture into Formula E.
