红牛引擎升级决定在即，意大利大奖赛前将揭晓
FIA预计本周内公布对F1动力单元制造商第二轮ADUO分析结果，红牛将在意大利大奖赛前得知其引擎能否在赛季末前进行升级。
红牛车队将在意大利大奖赛前得知，自己是否有机会在赛季末尾之前获得F1发动机升级的机会。
国际汽联（FIA）预计最早将于本周公布其对F1动力单元制造商性能的第二轮分析结果，该分析涉及额外研发与升级机会（ADUO）的相关规则。
今年早些时候，红牛曾措手不及，因为国际汽联在涵盖澳大利亚至加拿大大奖赛的第一轮ADUO审查中认定其为标杆发动机。
红牛被认定比其他所有制造商领先超过2%，这意味着它是唯一一家不被允许额外台架研发时间、研发支出以及推出新规格发动机的制造商。
车队方面不认同国际汽联（FIA）的调查结论，并要求该管理机构再次核查其数据以确保无误——随后进行了一次复核。
该复核的结果尚未公开发布，但据了解，没有任何证据能够改变国际汽联的看法。
在国际汽联的复核工作进行的同时，第二个ADUO时段也已结束。该时段从摩纳哥大奖赛持续到匈牙利大奖赛。
而且，根据与制造商达成的协议，国际汽联必须在一定时间窗口内将其调查结果通知制造商，以便为引入新的认证规格留出可能性。
据了解，公布第二次测量结果的截止日期在下周意大利大奖赛之前到期，因此有关这些发现的新闻，以及对其首个裁决进行审查的结果，应该很快就会公布。
第二个ADUO期间的结果对红牛赛季剩余阶段的计划至关重要，因为它将决定进入冬季的升级机会。
如果对红牛在摩纳哥至匈牙利期间表现的分析认定其落后于任何对手超过2%，那么这将为其获得开发机会打开大门——这可能使其在年底之前引入一次升级。
然而，如果再次认定其处于领先地位，甚至与最接近的对手梅赛德斯持平或在2%的差距之内，那么它获得任何额外开发机会的大门将会关闭。
如果红牛再次无能为力，那么2026年将剩下最后一次机会。
第三个ADUO时期从荷兰大奖赛持续到美国大奖赛，这将是各车队在2027赛季前的局面重置之前，在赛季中获得额外工作的最后一个窗口期。
这套系统已被证明存在争议，因为尽管梅赛德斯被普遍认为拥有最好的动力单元，但排名并非基于整体表现。
相反，这些排名只考虑了动力总成中的内燃机部分——而据了解，红牛在这一方面非常具有竞争力。
在夏休期前，国际汽联（FIA）单座赛车事务总监Nikolas Tombazis表示，未来或许可以商定一种新的测量方式——因为他认为管理机构在最初的分析中是对的。
"在我看来，我们的测量已被证明是非常准确的，"他说。
"话虽如此，一切都顺利吗？不，因为显然人们并不满意等等。那么我们是否需要考虑未来的改进？是的，我会这么说。"
不过，Tombazis淡化了这样一种说法：即红牛的对手们在获得ADUO之后，会现在钻系统的空子，放缓研发，让红牛永远无法提升而陷入困境。
这部分说法有一定道理，因为ADUO规则并不能给其他人提供任何保持落后的好处，因为收益在赛季中是不可累积的——所以一旦你获得了一次额外的开发机会，本赛季就到此为止了。
“我认为你一直待在下面并不合适，只是为了不断获得更多机会，”他说。“如果机会最终不是为了让你登上顶峰，那机会的意义何在？”
“我认为这个系统正按设计初衷运作。我确实认为它存在一些弱点，我们将来需要解决，这是肯定的，以让它更省时、更少争议。我们确实需要在未来采取一些措施来改进它。”
英文原文
Red Bull is set to find out before the Italian Grand Prix whether there will be any scope for it to get the opportunity for Formula 1 engine upgrades before the tail-end of the year.
The FIA is expected to announce as early as this week the findings of its second round of analysis of the performance of F1's power unit manufacturers in relation to the rules surrounding Additional Development and Upgrade Opportunities (ADUO).
Earlier this year, Red Bull was caught by surprise after the FIA deemed it to be the benchmark engine during the first round of ADUO auditing that covered the Australian to Canadian Grands Prix.
Red Bull was deemed to be more than 2% ahead of every other manufacturer, which meant it was the only one that would not be allowed extra dyno development time, spending, nor the ability to introduce a new specification.
It did not agree with the FIA's findings and requested the governing body check its data once again to be sure - with a review subsequently taking place.
The outcome of that review has not been released in public yet, but it is understood there was no evidence of anything that changed the FIA's opinion.
While work on the FIA review has been ongoing, the second ADUO period also concluded. That ran from the Monaco GP to the Hungarian GP.
And, under the agreement with manufacturers, the FIA has to notify them within a certain window of the outcome of its findings to ensure the door is open for the introduction of new homologation specifications.
It is understood that the deadline for announcing the result of the second measurement expires before the Italian GP next week, so news of these findings, as well as the outcome of its review into the first verdict, should be imminent.
The outcome of the second ADUO period is critical to Red Bull's plans for the remainder of the campaign because it will dictate upgrade opportunities into the winter.
If analysis of Red Bull's performance over the Monaco-Hungary period deems it to be more than 2% behind any of its rivals, then that will open the door for it to be granted development opportunities - which could allow it to introduce an upgrade before the end of the year.
If, however, it is once again deemed to be ahead, or even on equal terms or within 2% of closest rival Mercedes, then the door will be shut for it to have any extra development chances.
If Red Bull's hands are tied once again then there will be one final opportunity left in 2026.
The third ADUO period runs from the Dutch GP to the United States GP, and will be the last window for teams to get extra work in-season before things reset ahead of the 2027 campaign.
The system has proved to be controversial because while Mercedes is widely viewed to have the best power unit, the rankings are not based on overall performance.
Instead, they only take into account the internal combustion engine element of the package - where Red Bull is understood to be very competitive.
Speaking before the summer break, the FIA's single-seater director Nikolas Tombazis suggested that perhaps a new way of measuring things in the future could be agreed - as he reckoned the governing body had got it right with its initial analysis.
"Our measurement, in my opinion, has proven to be very accurate," he said.
"With that said, has everything worked fine? No, because obviously people are not happy and so on. So do we need to think about improvements in the future? Yes, I would say so."
Tombazis has played down suggestions, however, that Red Bull's rivals, having earned ADUO, would now game the system to hold back on developments and leave Red Bull trapped by never being able to improve.
This is partly true because ADUO rules do not offer any benefit for others to remain adrift as the gains are not cumulative during the season - so once you are granted extra development once that is it for the season.
"I don't think it would be convenient for you to always be below, just to sort of keep getting more opportunities," he said. "What's the point of opportunities if it isn't ultimately for you to be on top?
"I think the system is working as it was designed. I do think there are some weaknesses that we need to address in the future, for sure, to make it less time-consuming, less controversial. We do need to make some steps to improve it in the future."
