The Haas team dealt with their 2022 upgrade approach very differently from other F1 teams by not making any major changes to the VF-22 early, but after gathering data during the first half of the 2022 campaign they only applied their upgrades at the recent Hungaroring race.
In an interview on the RacingNews365.com podcast, Steiner said there will be no more major update for Haas this year as the team was switching focus on the 2023 season, with nine races still remaining this season
"For the rest of the year it will be very little [in terms of development]," Steiner said.
"We focus already on the 2023 car since a few months. We still do some little work on the '22 car, but we're looking always a little bit forward.
"Obviously what you learn this year you carry on next year, because the regulations don't change. It was not like from '21 to '22. But we have got our sight on '23 in the moment.
"We developed this upgrade [for the 2022 car] and then we produced it. Maybe we'll come with a few small parts, but nothing [else] big for this year."
Despite Haas' struggles for decent results over the past few years, Steiner confirmed their focus was to find consistency going forward.
"Coming back in '22 with the result we had in Bahrain (fifth place with Kevin Magnussen), it was very good for the team, mainly because [for] a lot of people last year it was difficult to see the light at the end of the tunnel," Steiner said.
"Fortunately, or because of the hard work of the design and aero department, we got a good car out there for this year and we bounced back.
"I think what we need to work now on is to stabilise our performance.
"We had the first two [races] good, and we had five or six races not so good, then we had again good races, now we had again a few bad races, so we need to find a happy medium there."
