Haas team principal Guenther Steiner has said Renault only lodged a complaint to the FIA because they cannot beat them.
Romain Grosjean’s P6 finish in Monza has currently been scrubbed off by the FIA after finding that Haas had used an illegal floor at the Italian Grand Prix.
The investigation was launched after Renault, who are locked in a fierce battle with Haas for P4 in the Constructors’ Championship, lodged an official complaint with the FIA.
“If they cannot beat you on the track, they try to beat you in court,” Steiner said in his official race preview for Singapore.
“That is what seems to be happening. You have to work hard to be envied. We’d rather work hard for it and fight even more.
“Sometimes, you have to do that [lodge complaints]. You take any approach in racing. Is it the right thing to do? I’ll let others determine that.”
Haas have officially filed their appeal and the fall-out from the Italian Grand Prix between the two teams is set to drag on into another week.
But Steiner is adamant that the ongoing dispute will not distract anyone from the job in hand.
“This doesn’t distract me,” he added. “Our people know where they need to put the effort in.
“We don’t get distracted when we go racing. We try to always get good results in racing and leave the other stuff offline.”
