Haas are running a heavily-updated car at this weekend's Hungarian Grand Prix, having brought much-anticipated new parts to the track.
After opting against any significant changes over the first half of the season, the team have applied a new floor, bodywork and suspension to the VF-22, among other items.
However, only Kevin Magnussen will run the upgrades this weekend due to a lack of parts and the Dane's advantage over Mick Schumacher in the standings.
Haas' shortage of new parts is related to delays in their development, a situation not helped by Schumacher's two heavy crashes in Saudi Arabia and Monaco.
The full list of changes includes a new floor body, fences and edge, along with a modified coke/engine cover, cooling louvres, rear suspension and rear corner.

Limited updates elsewhere, nothing for Ferrari
Beyond Haas, the rest of the F1 field have opted to bring only limited updates to the Hungaroring, or make no changes at all.
Mercedes have made some performance-based tweaks to their Halo (adding a slat to the fairing), rear wing and beam wing, with Red Bull also using a new beam wing.
McLaren are running a modified front corner (circuit-specific cooling) and an updated diffuser, while Alpine have upgraded their beam wing and Alfa Romeo their floor body.
AlphaTauri and Aston Martin have made adjustments to their rear wings (both circuit-specific for drag) – the AMR22's new rear wing tip catching the eye.
Meanwhile, Ferrari and Williams have not reported any updates to their cars between the French and Hungarian GP weekends.
