Eight of the ten teams prepared certain new products for the US Grand Prix, some presented a very extensive list of improvements, others limited themselves to minimal changes, and Ferrari and Williams reported nothing at all.
What’s strange is that James Vowles said at a fan meeting in Austin that his team had “made a few more improvements before this weekend to take the next step forward.” However, in the FIA’s official report, the Williams page is blank.
Red Bull racing
On the cars of the champion team, the geometry of the edges of the underbody, or more precisely, its individual elements, has been changed, which was done to increase the downforce created in this area of the aerodynamic body, as and to stabilize airflow.
In addition, the engine housing has been redesigned to improve the efficiency of the cooling systems.
Mercedes
Lewis Hamilton and George Russell’s W15 features redesigned front wings in combination with individual front suspension components to improve airflow to the rear of the car.
Additional elements have appeared at the front of the underbody to increase the volume of air directed under the underbody, which is designed to improve the efficiency of this important part of the aerodynamic body kit.
The shape of the air intakes on the side of the pontoon has changed slightly – their lower edges have become slightly more elongated – this should have a positive effect on the efficiency of the cooling system of the power plant.
At the rear of the engine housing, additional fins appeared to remove the warm air from this system and the geometry of the baffles at the bottom was adjusted.
McLaren
McLaren has unveiled a seven-point list of changes affecting the front and rear wings, front and rear suspension and brake ducts.
The adjustments to the front wing, front suspension and brake ducts should be taken as a whole: primarily they are aimed at improving airflow properties. At the same time, as reported by Auto Motor und Sport, the updated wing exists in one copy, and although both drivers will try it out during training, it will remain on Lando Norris’s MCL38 in the future.
But both cars feature optional single-plane rear wings to reduce drag, and they work in tandem with a more efficient rear wing designed for more downforce.
The rear brake air ducts were modified based on U.S. highway specific brake cooling requirements.
Aston Martin F1
The Silverstone team has, as promised, prepared a whole range of new products for the American Grand Prix, focusing on the front wing, engine housing, underbody and diffuser.
The adjustable element on the front fender has been updated and the geometry of the end plates has been changed to improve the overall efficiency of this part of the aerodynamics kit.
It is also reported that significant changes have been made to the underside of the AMR24, including the edges, allowing it to operate more efficiently when combined with an improved motor housing. The diffuser, which works together with the improved bottom, has also undergone some changes.
Alpine F1
The factory team of the Renault concern also brought new items in one copy, and only Pierre Gasly will receive them: we are talking about a new underbody, rear wing and engine case with a slightly modified profile.
Visa RB
Yuki Tsunoda and Liam Lawson’s cars have a redesigned underbody in the hope that it will generate more downforce and reduce efficiency losses.
Sauber
The Swiss team reports that the geometry of all elements of the C44 front wing has been revised and improved, which has a positive effect on the properties of the flow flowing around the car, as well as providing more downforce. Modernized fairings of the front suspension elements also work in tandem with the wing.
The rear lower control arm fairings and rear brake air ducts have also been improved.
Haas F1
The car of the American team received a modernized bottom, changed the geometry of the air intakes of the side pontoons and the engine case, on which larger openings appeared to remove hot air from the power plant.
