迈凯伦升级带来惊喜，诺里斯圣保罗一练最快
诺里斯在圣保罗大奖赛周五对迈凯伦最新升级给出谨慎肯定，他在第一节练习中领先安东内利0.082秒排名最快。
迈凯伦的升级是“一个惊喜”——但它会留在巴西站赛车上吗？
诺里斯在圣保罗第一节练习中跑出最快圈速，并表示迈凯伦的最新套件“似乎带来了我们期望的效果”，让MCL40的一些粗糙之处变得平顺。
在经历了自2010年简森·巴顿以来最动荡的一次世界冠军卫冕之后，诺里斯在圣保罗大奖赛周五对迈凯伦最新一批赛车升级给出了谨慎的肯定。诺里斯在第一节练习中排名最快，领先梅赛德斯的基米·安东内利0.082秒，并且在第二节练习的长距离平均速度上也位居最快之列。
“第一节练习确实有点意外，是一个惊喜，”诺里斯说。
“二练中，我觉得相比梅赛德斯我们似乎更挣扎一些，基本上每圈都慢两成。但相对于其他一些车手，我认为我们看起来相当不错。
“升级方面，尽管我先用了一半、再用另一半，明天我们会把所有东西整合起来，但可以说升级似乎也带来了我们期望的效果。所以我认为就完成测试计划而言这是不错的一天，就相对性能而言也是不错的一天。”
本赛季两位正赛车手的反馈都集中在：要从MCL40中榨出一圈快圈需要付出多大的努力——这是一辆必须被牢牢驯服的车。这不仅不利于实现排位和正赛所需的一致性，考虑到轮胎对打滑造成的表面温度骤升十分敏感，它还在两位车手之间制造了隔阂。
正如车队领队安德烈亚·斯特拉反复强调的那样，皮亚斯特里是一位通过整个比赛周末逐步积累而渐入佳境的车手。这需要赛车所无法提供的一致性。诺里斯适应性更强，但即便是他也难以拼凑出一个完整的比赛周末；例如在墨西哥，他说赛车在周日有夺冠的速度。他的问题在于周六赛车没有足够的速度让他排到第六名以上。
迈凯伦在这一连串三站比赛中分阶段引入了一项重大升级，为奥斯汀美国大奖赛增加了新的前悬挂几何结构以及修改后的扩散器部件。现在又加入了进一步的空气动力学精雕细琢，其中最引人注目的是新前翼，其三片翼面均经过重新塑形，整个组件通过中间翼面而非前翼面安装到鼻锥上。此外，后翼及其底部横梁以及底板也进行了修改。
所有这些都在九月初获得批准，随后设计团队全面转向2027年赛车项目。此次升级的总体重点在于让赛车在制动时略微更具可预测性，并略微改善驾驶性，同时略微提升整体性能上限。

赛车的一些难以驾驭的特性是‘固有的’，无法通过空气动力学修改来抹平：为了更有把握地达到这一代新车 somewhat 雄心勃勃的减重目标，迈凯伦选择了尽可能短轴距的紧凑型赛车。但这损害了稳定性，并在后轮前方底板面积方面强加了固有的空气动力学限制。
诺里斯表示：“你总是把东西推到极限，所以一旦你感觉可能稍微更舒服一点，你就会自动地继续推，直到再次找到极限。”
“归根结底，升级是为了带来圈速和性能。它们并非只是为了改善操控。完美的升级是既能带来圈速，同时又能带来操控升级，尤其是考虑到这辆车一直多么难以驾驭。”
“我想说，也许在正确的方向上有一个小变化，因为驾驶起来似乎稍微更直接一点，但我不认为我们能仅凭一条赛道就判断事情。但到目前为止，今天的事情似乎稍微更直接一些，这是好事。”
尽管诺里斯预计周六会运行完整套件，他在周五评估了混合部件，而莱昂纳多·福尔纳罗利在他强制性的第一节练习‘新秀跑’中完成了大部分耙式测试，但这并非100%确定，尽管车队持乐观态度。
“我认为升级看起来正如我们预期的那样在发挥作用，这已经是你所能要求的一切了，”赛事总监兰迪·辛格说道。
“而且莱奥·福纳罗利在第一节练习赛中为我们做得很好，真正运行了一些耙具并帮助我们详细测试了它们。”
“我们今晚会做出最终决定，但到目前为止所有数据看起来都不错。不过我们会尽职尽责，也检查第二节练习赛的所有数据。但是的，我认为很可能所有升级都会保留。”

McLaren’s upgrade is "a pleasant surprise" – but will it stay on the car in Brazil?
Lando Norris went fastest in first practice at Sao Paulo and said McLaren’s latest package "seems to have given what we hoped for" in smoothing off some of the MCL40’s rough edges
After one of the most turbulent world championship defences since Jenson Button in 2010, Lando Norris gave McLaren’s latest batch of car upgrades a cautious thumbs-up on the Friday of the Sao Paulo GP. Norris topped the first practice session, edging out Mercedes’ Kimi Antonelli by 0.082s, and was among the quickest in terms of average pace on his long runs through FP2.
"Certainly FP1 was a little bit of a surprise, a pleasant surprise," said Norris.
"FP2, I think we seemed to struggle a little bit more compared to the Mercedes, just two tenths off on every lap basically. But relative to some of the others, I think we seem pretty good.
"The upgrades, even though I had half and then half, and we're going to put everything together for tomorrow, the upgrades also seem to have given what we hoped for, I would say. So I think it's been a good day in terms of getting through the run plan and also a good day for relative performance."
The feedback from both race drivers this season has focused on how much effort is required to wring a fast lap out of the MCL40: it’s a car which really has to be taken by the scruff of the neck. Not only does that militate against achieving the consistency required to qualify and race well, given the sensitivity of the tyres to spikes in sirface temperatures caused by sliding, it has driven a wedge between the two drivers.
Piastri, as team principal Andrea Stella has repeatedly emphasised, is a driver who thrives on building through a weekend. This requires a consistency the car cannot deliver. Norris is more adaptable but even he has laboured to put a complete weekend together; in Mexico, for instance, he said the car had the pace to win on Sunday. His problem was that it didn’t have the pace on Saturday for him to qualify higher than sixth.
McLaren has introduced a substantial update in phases through this triple-header, adding a new front-suspension geometry as well as revised diffuser furniture for the US GP in Austin. This has now been joined by further aerodynamic finessing, headlined by a new front wing in which all three planes have been reprofiled and the whole assembly mounts to the nose via the middle plane rather than the front. Elsewhere there have been revisions to the rear wing and the beam at its base, along with the floor.
All of these were signed off at the beginning of September before the design team pivoted fully towards the 2027 car project. The overall focus of the update has been to make the car slightly more predictable under braking, and to improve the driveability slightly while elevating the overall performance ceiling slightly.

Some of the car’s truculence is ‘baked in’ and cannot be smoothed off by aerodynamic revisions: to be more certain of hitting the somewhat ambitious reduced weight limit for this new generation of car, McLaren opted for a compact car with the shortest wheelbase possible. But this compromised stability as well as enforcing inherent aero limitations in terms of the floor area ahead of the rear wheels.
"You're always pushing things to the limit, so as soon as you feel something maybe a little bit more comfortable, you automatically push it until you find the limit again," said Norris.
"Ultimately the upgrades are there to bring laptime and performance. They're not set out just to improve handling. A perfect upgrade is one that brings lap time and at the same time brings a handling upgrade, especially with how tricky the car's been.
"I would say maybe there's a small change in the right direction in that it seems just a little bit more straightforward to drive, but I don't think we can ever judge things over just one track. But so far for today things have seemed a little bit more straightforward, which is a good thing."
Although Norris expects to run the complete package on Saturday, having evaluated a mix of components on Friday while Leonardo Fornaroli did the majority of the rake testing during his mandatory FP1 ‘rookie run’, this is not 100% certain, even though the team was optimistic.
"I think the upgrades look like they're delivering as we expected, which is all you can ask for," said racing director Randy Singh.
"And Leo [Fornaroli] did a good job for us in FP1 of really running some rakes and helping us test them in detail.
"We'll make the final decision tonight, but all the data so far looks good. But we'll do our due diligence, check all the data from FP2 as well. But yeah, I think likely all the upgrades will stay on."
