Kevin Magnussen will be the sole recipient of Haas' upgrade package at the Hungarian Grand Prix, with Mick Schumacher missing out due to a lack of suitable parts.
This is Haas' first major upgrade of the 2022 season, but without enough parts to service both cars, Magnussen will get the updates thanks to his superior position in the Drivers' Championship.
"As many people know, we waited a bit longer to bring our upgrade to track because I think we still have good pace," Haas Team Principal Guenther Steiner told media including RacingNews365.com.
"Now what we want to do is put performance on. We know what it should be doing from our development. We'll just have to wait and see what we can get out of the package."

Development delays led to parts shortage
Steiner added that the shortage of new parts was related to delays in their development, a situation not helped by Mick Schumacher's two heavy crashes in Monaco and Jeddah that required replacement parts to be built.
"In the end, we couldn't get two car kits to the race track, so with Kevin being in front in the championship, we gave him the package to try," said Steiner.
"Unfortunately, we had a few delays in the development stage, so we postponed it from the French Grand Prix to Hungary.
"Also, with the spares situation we had at the beginning of the season, up to race seven or eight, we fell a bit behind in production and therefore we don’t have enough parts for two cars.
"We struggle with spare parts for one car so hopefully we can get it done and bring it to Hungary.
"Everybody has worked really hard – the team and our suppliers – to make this happen so I'm still very happy that we bring it on one car to Hungary.
"We want to get some data before the summer break so we have something to work from when we get back, and if all goes well we'll have it on both cars."
Despite having only made minor changes to the VF-22 since the start of the season, Haas are currently seventh in the Constructors’ Championship, with Magnussen scoring the team's best result since 2018 with fifth place at the Australian Grand Prix.
