Haas excluded for floor infringement
Romain Grosjean was excluded from sixth place at Monza after the floor of his Haas was found to be illegal following a protest by the Renault team. The stewards ruled that the reference plane – the lowest point of the car other than the wheels – did not comply with Article 3.7.1d of the technical regulations. This states:“the surface formed by all parts lying on the reference plane must have a 50mm radius (+/2mm) on each front corner when viewed from directly beneath the car, this being applied after the surface has been defined.” The stewards also referenced a subsequent technical directive, issued on July 25, that clarified the regulation because it was “being applied differently by several different teams”. This required Haas to modify the floor, which has run in this configuration since June’s Canadian Grand Prix, by the Italian GP. Haas had informed FIA head of single-seater technical matters Nikolas Tombazis in an email that it aimed to do so for September’s Singapore GP, arguing that the mandatory summer shutdown delayed production of a new floor. Stewards confirmed Tombazis did not respond to that specific point, replying to technical details in the same email, which Haas took to mean it could continue on its timeline. But as Tombazis confirmed he had told Haas head of aerodynamics Ben Agathangelou in conversation that this would leave Haas open to a protest, the stewards accepted no such extension had been granted. The infringement relates to the T-tray at the front of the floor, which must be shaped in a certain way. The 50mm radius was adhered to for the floor itself, but the connection of a new footplate design to the splitter changes the way in which the radius was viewed from directly beneath the car, as stipulated by the rules. Haas served notice of its intent to appeal on Sunday night, but as Autosport closed for press had yet to confirm it was proceeding.
