Haas have made the decision to protest the cars of Alpine driver Fernando Alonso and Red Bull racer Sergio Perez in the wake of the United States Grand Prix.

    A positive race for the American team on home soil saw Kevin Magnussen claim P9, for Haas’s first points since the Austrian Grand Prix – on the weekend where the team confirmed new title sponsor MoneyGram for 2023.

    But after the race, Haas lodged a pair of protests against Perez and Alonso’s cars, which the FIA stewards later deemed admissible. It’s believed the protests relate to damage incurred on the Alpine and Red Bull machines – the former from contact with Lance Stroll, the latter from a touch with Valtteri Bottas – neither of which were warned with a black-and-orange flag.

    Haas have previously spoken publicly at their annoyance of Kevin Magnussen having received three such black-and-orange flags – which require the driver to pit as soon as possible if they’ve suffered a mechanical issue that’s deemed to be unsafe – in 2022, the most recent coming at the Singapore Grand Prix.

    “Twelve years apparently there were no black-and-orange flags,” said Haas Team Principal Guenther Steiner in Singapore. “I don't know where they found this rule again and now are happy to apply it, and especially to us.”
