On several occasions this season, including most recently at the Canadian Grand Prix, Haas has seen high grid spots turn into lowly finishing positions as a result of its problem, which is exacerbated running in traffic in race situations.
Nico Hulkenberg qualified second in Montreal and then started fifth after being hit with a penalty for driving too fast under the Q3 red flag, but came home 15th.
He said afterwards that “there's nothing really that we can do with set-up to fix this - it's bigger issues” and called for Haas to implement a “longer-term strategy that we need to pursue to get really much better at it”.
As part of this at this weekend’s Austrian GP, Haas has introduced a new pitot static sensor on the middle part of the nose on the VF-23.
The new part, according to Haas’s explanation in the FIA document where all teams are required to explain upgrades, is of a “lower aerodynamic disturbance” and has “an improved functionality in the operations and data analysis”.
