2026年美国大奖赛：法拉利公布最大升级
法拉利在美国大奖赛前夕公布了比其车手们所暗示的更具意义的F1升级。尽管汉密尔顿和勒克莱尔淡化了对最新发展的预期，但官方FIA提交中法拉利的改动在性能关键区域相当广泛。
法拉利在美国大奖赛前夕公布了比其车手们所暗示的更具意义的F1升级。
这原本预期是一个大包，但刘易斯·汉密尔顿和查尔斯·勒克莱尔都淡化了对最新发展所预期的进步。
汉密尔顿在周四表示：“这个周末我们只有一个非常小的升级。不到十分之一。就像半十分之一。”
然而，在官方FIA提交中，每个车队都必须声明其带来的改动，法拉利的改动在性能关键区域相当广泛。
它们包括更新的板式加强布局，以及重新设计的前地板前缘，以及对两侧垂直和水平板元素的重新塑造。
此外，侧箱入口和提前进站的形状已被改变，以帮助空气更好地与下面的地板互动。
在此基础上，法拉利还对扩散器体积进行了修订，包括新的围栏负载和后缘外板组件。
车队表示，这些更新专注于增加车辆前后地板的下压力，以及增加后部的能量水平和流动稳定性。
麦凯轮车队更新刹车导流板和扩散器
麦凯轮车队在奥斯汀站对其赛车进行了进一步的升级，前后刹车导流板进行了修改以帮助改善气流条件并增加下压力。
车队还对扩散器的几何形状进行了微调，以改善空气流动并增加全速度范围内的下压力。
红牛车队对其前翼进行了微小修改，增加了一个新的叶片以帮助监控其前轮胎温度。目前这只是为了评估目的。
小红牛也在美国大奖赛周末推出了一个重量级的更新包，以期巩固其在四大车队之后的最佳成绩地位。
这些更新包括新的前翼端板、新的后翼襟翼以及地板边缘、前缘和地板板（以前称为导流板）的众多改进，所有这些改进都是为了提高下压力。
小红牛还对其发动机罩进行了重新设计，采用了新的肩部和未切割的设计。
奥迪对其前刹车通道进行了修改，并引入了新的地板板几何形状以改善局部流场条件。它还将运行一个新的后视镜支架。
阿尔法·罗密欧对其后翼的第二和第三元素襟翼进行了重新设计，以改善空气流动条件，并对其后地板的角落进行了重新设计，以帮助增加下压力。
凯迪拉克更新了其前地板的几何形状，并对其侧箱的冷却百叶窗进行了调整。

Ferrari has revealed a potentially more significant Formula 1 upgrade than its drivers let on ahead of the United States Grand Prix.
This was anticipated to be a big package but both Lewis Hamilton and Charles Leclerc played down the step forward that was anticipated from the latest developments being added to its car for this weekend's race at the Circuit of the Americas.
Hamilton said on Thursday: "We have a very, very small upgrade this weekend. It's less than a tenth. It's like half a tenth."
However, in the official FIA submission where each team has to declare what it has brought, the Ferrari changes are quite extensive in performance critical areas.
They include an updated board brace layout, and a redesigned front floor leading edge, as well as a reshaping of both inboard vertical and horizontal board elements.
Furthermore, the shape of the sidepod inlet and undercut has been altered to help airflow better interact with the floor below.
On top of this, Ferrari has a revised diffuser volume, with new fence loading and trailing edge outboard furniture.
The team said the updates are focused on increasing floor downforce at both the front and rear of the car, as well as increasing energy levels and flow stability towards the back.
McLaren updates brake ducts and diffuser
McLaren has brought further upgrades to its car at Austin, with brake-duct revisions at the front and rear to help improve flow conditioning and increase downforce.
The team has also tweaked its diffuser geometry to improve airflow and increase downforce across the speed range.
Red Bull has made a minor revision to its front wing, adding a new vane to help with the monitoring of its front tyre temperatures. This is for evaluation purposes so far.
Racing Bulls has also used the US GP weekend to introduce a hefty update package as it bids to secure its best-of-the-rest status behind the top-four teams.
Its changes include a new front wing endplate, new rear wing flaps and a number of enhancements across the floor edges, the leading edge and the floorboards (formerly bargeboards), all aimed at improving downforce.
Racing Bulls has also reprofiled its engine cover with a new shoulder and uncut.
Audi has made revisions to its front brake duct as well as introducing new floorboard geometry to improve local flow conditioning. It will also be running a new mirror stay.
Alpine has reprofiled the second- and third-element flaps of its rear wing to improve airflow conditioning, and has redesigned its rear floor corner to help increase downforce.
Cadillac has updated its forward floor geometry and tweaked the cooling louvres on its sidepods.
