Ferrari SF70H detail front wing 1 / 29 Photo by: Giorgio Piola Ferrari has introduced a new front wing for the US GP, which features a shorter endplate and another aggressively out-turned vane that's anchored to the rear of it (arrowed).

Ferrari SF70H diffuser 2 / 29 Photo by: Giorgio Piola After Ferrari toyed around with a new diffuser concept in the post-Hungarian GP test but failed to race it, the team is set to trial another design in Austin. The revised layout features a flat central section (white arrow), rather than the curved one used previously (see inset). Meanwhile, another vertical fence has been added to the side of the crash structure in order to work the airflow harder and assist the revision below.

Haas F1 Team VF-17 barge boards 3 / 29 Photo by: Giorgio Piola Haas has introduced a sizeable update package, which includes the revised bargeboard and new sidepod deflector pictured here. The bargeboard features a series of serrations in the footplate (red arrow), while the deflector (blue arrow) is a horizontally-louvred panel in a similar vein to the appendage used by Ferrari throughout 2017 and recently introduced by Red Bull in Singapore.

Williams FW40 barge boards 4 / 29 Photo by: Giorgio Piola Williams continues to optimise the FW40 as the season draws to a close, with the deflectors introduced a few races ago now floated rather than the forwardmost element being anchored to the floor. The team has also revised the floor's axehead inline with these changes in order to bolster performance in that area of the car.

Sauber C36 without a fin 9 / 29 Photo by: Giorgio Piola Sauber have introduced a new engine cover for Austin, which features a more conventionally-tapered spine, rather than a shark fin, and is devoid of the T-Wing entirely.

Mercedes AMG F1 detail 11 / 29 Photo by: Giorgio Piola Mercedes is seemingly looking to run its conventionally-shaped rear wing for the US GP, rather than the ‘spoon’-shaped wing we’ve seen used previously this season.
