Sauber's development has stagnated this season as the team struggles with funding but it is hoped that with some fresh investment coming through the team can add some development going into the latter stages of the season.
This is of particular importance given that Pascal Wehrlein scored point for Manor last time out and now threatens the Swiss team's chances of recovering its championship position this season.
This new wing won't be used at Silverstone and is simply a test for next time out in Hungary, with the team using flo-viz to ascertain if the wing is working as expected under full-size conditions.
The new wing is quite an undertaking for the team, with several new airflow-conditioning elements being used, whilst the Y-shaped centre mounting pylon has been disposed of in favour of a singular mount.
The endplate utilises similarly shaped louvres to what Toro Rosso introduced at the start of the season and have now been copied by Mercedes too; whilst four gradient slots, which allow pressure to bleed from the outside of the endplate inboard and energise the flaps have also been added.
The singular pylon still intersects with the exhaust as did its predecessor in order to shape the exhaust plume dissipated by the turbo, whilst the monkey seat that previously hung from the Y-shaped pylon has been replaced by a more standard appendage that is mounted to the crash structure.
The illustration above shows the contrasting design features of the wing that has been used by the team so far this season.
