Grosjean’s car “not in conformity” with floor regulations

2018 Italian Grand Prix

Romain Grosjean’s Haas has been found to be ‘not in conformity’ with technical regulations after a protest by Renault led to stewards investigating the floor of the car.

After an investigation into the reference plane of Grosjean’s Haas, the stewards determined that it did not adhere to the regulations. No word of any punishment or penalty has been made by the FIA, but the breach will likely result in disqualification. This would promote Sergei Sirotkin into tenth, giving him his first points of his Formula One career.

Specifically, the stewards found the Grosjean’s car, which was classified in sixth in the Italian Grand Prix, was not in compliance with Article 3.7.1 D) of the Technical Regulations.

    1. Does that mean Sirotkin will now score his first ever point?

      1. Not yet but likely will be announced soon

    2. Likely disqualification then.

    3. So the SF70-H floor was illegal back in 2017 ?

      1. @tifoso1989, I believe that, in the pre-season tests, the floor on Ferrari’s current car was initially not in compliance with the regulations and subsequently had to be modified to make it compliant. However, I understand that was because it breached a different part of Section 3.7.1 (the rule on not having visible holes in the floor when viewed from directly above), not the section Haas have been deemed guilty of breaking.

        In this case, what they appear to be saying is that the front corners of the floor do not have the required radius of 50mm, plus or minus 2mm, as specified in that regulation. I suspect that it is more likely to be down to a production issue – equipment calibration issues, mismeasurement by the user and so on – that has resulted in a slight mistake in the shape of the front of the floor, rather than a deliberate attempt to cheat the regulations.

        As others have noted, given the precedent set in the past – for example, with the disqualification of Sauber in 2011 from the Australian GP – the odds are that Grosjean will be disqualified for what sounds like an unfortunate breach of the rules, but nevertheless a case of the team using a part that doesn’t comply with the regulations.

        1. Please, can anyone tell me how Renault was aware of the possible issue? During technical discussions among FIA and teams or?

    4. Doesn’t seem to catch a break. Poor Grosjean, he has been good those past 5 races

    5. So from a pdf of the rules article 3.7.1 D) is (about the Step and reference planes):

      Additionally, the surface formed by all parts lying on the reference plane must …
      d) 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.

    6. So, would this mean that a) Grosjean used a different/new floor here, b) Renault protested only Grosjean, because they didn’t care for Magnussen since he finished behind them or c) The floor was not in compliance due to damage?

      Not sure even what the infringement would be – a sharp-is edge on the front of the floor?

      1. damage during a race doesn’t normally count as an infringement, this is likely to have been an issue on the car pre – race

      2. So from what @ellybabes says, I think it probably is b) @bascb – and thanks for quoting the regulation above. So, likely the floor was too ‘sharp’ edged I guess.

    7. see other topic, but again..
      The FIA did not responded to Haas.

      They said Haas had breached article 3.7.1 d of the Technical Regulations, which focuses on the radius of the leading corners of the floor’s reference plane.

      Back in July, governing body the FIA issued a Technical Directive clarifying the regulation and stipulated that teams must bring their cars into conformity before the Italian Grand Prix.

      It emerged during the hearing that Haas emailed the FIA, as is common in these matters, with details of their new solution but because of the limited time, given the summer break and two-week shutdown, they had asked for some flexibility in the matter.

      They said they would “endeavour to introduce this upgrade for the Singapore GP but will be somewhat at the mercy of our suppliers”.

      The FIA did not respond to the latter point, with Haas telling the stewards at the hearing that it was their understanding that “a lack of response on the matter of timing that their solution and timing were accepted”.

      But the stewards said in their statement: “While the Stewards are also sympathetic to the difficulties of producing these parts, the Stewards noted that at least one other competitor was able to comply in the time provided.

      1. Failure to reply does not excuse failure to comply with the prevailing regulation.
