Mercedes F1 team principal Toto Wolff said he was not concerned about any problems developing with the rules.
Wolff said governing body the FIA had been involved throughout the design process.
"It's clear that sometimes when you come with an innovation it creates the kind of debate we're having here," Wolff added. "It was expected.
"We were keen in not running alone with that, but being in touch with the FIA. That's why I think it will be OK."
