McLaren CEO Zack Brown says it is extremely important that Formula 1 introduces the new planned regulations for the 2021 season. The sport is set to run with revised engine and aerodynamic rules, however a number of teams have been opposed to their introduction.
But Brown fears that only two or three teams will be able to compete for the world championship if changes aren't made: "We have a journey to get back to winning races," he said. "And once you’re winning races you’re competing for the championship.
"I think it’s critical that Liberty make the changes to the sport that we discussed earlier because right now, the way the sport is going, it’s difficult for more than two or three teams to compete for the championship.
"So I think the things that are out of our control but hopefully we can influence, they need to change for multiple teams to be able to win races and compete for the championship. But we have laid out a journey, a message, a road of recovery that sees us getting back to the front of the grid in that time."
F1 will have new regulations in force this year, with aerodynamics being reduced after growing concerns about the quality of on-track racing. However, there are doubts that the new rules will have much of an effect, with teams finding new ways to produce similar levels of downforce.
McLaren will be targeting a more successful year in 2019 after managing sixth place in the constructors' championship last year. The Woking squad has recruited former Toro Rosso and Renault driver Carlos Sainz to partner rookie Lando Norris.
