梅赛德斯推迟ADUO引擎首秀
梅赛德斯升级的F1引擎不会像最初预期的那样在美国大奖赛上亮相。由于梅赛德斯被认为比基准2026动力单元（红牛）落后超过2%，因此它可以引入中期升级。
梅赛德斯升级的F1引擎不会像最初预期的那样在美国大奖赛上亮相。
梅赛德斯被认为比基准2026动力单元（红牛）落后超过2%，由F1的额外开发和升级机会（ADUO）系统判定，这意味着它可以引入中期升级。
原计划在本周末奥斯汀引入升级，但因动力单元未准备好而推迟。
《The Race》了解，它也不会在下周末的墨西哥大奖赛准备好，这意味着F1最新三连赛的最后一站巴西大奖赛很可能是它最早到达的日期。
乔治·拉塞尔在本月伊始在雪邦遭遇的引擎故障对他来说是个打击，因为这意味着他在新加坡需要接受发车线处罚。
每次他使用ADUO梅赛德斯引擎时，他都必须接受另一个发车线处罚。
梅赛德斯只有在确信这是真正的一大步时，才会引入ADUO引擎。
车队几乎肯定将赢得2026年的两项冠军，但任何在2026年底引入的赛车和引擎升级都将对2027年产生重大影响。
所以，无论梅赛德斯在其ADUO引擎上能取得多少进步——即使它只用于2026年两三个周末——对下一年来说都可能非常有用。
梅赛德斯将在奥斯汀使用它在雪邦首次亮相的主要底盘升级，因为它在上次新加坡的比赛中采取了不同寻常的方法，将规格分给了两辆赛车。
那次实验在新加坡周末期间让梅赛德斯学到了很多，而自那以后团队完成的简报又给了它更多关于如何最好地利用升级的线索。
两位车手将从FP1开始就拥有升级后的赛车。
英文原文
Mercedes’ upgraded Formula 1 engine won’t appear as initially expected at the United States Grand Prix.
Mercedes was deemed to be more than 2% adrift of the benchmark 2026 power unit (Red Bull) by F1’s Additional Development and Upgrade Opportunities (ADUO) system, meaning it can introduce a mid-season upgrade.
That upgrade was initially pencilled in for introduction at Austin this weekend, but that plan has been pushed back because the upgraded power unit isn’t ready.
The Race understands it won’t be ready for next weekend’s Mexican Grand Prix either, meaning the Brazilian Grand Prix that concludes F1’s latest triple-header is the likely earliest date it will arrive.
George Russell’s engine failure at Sepang at the start of this month was a blow for him as it meant he had to take a grid penalty in Singapore.
He’ll have to take another grid penalty whenever he takes the ADUO Mercedes engine.
Mercedes only wants to introduce the ADUO engine when it’s convinced it’s a proper step forward.
The team’s all but certain to win both 2026 titles, but any car and engine upgrades introduced in late-2026 will have a significant impact on 2027.
So whatever progress Mercedes can make with its ADUO engine - even if it’s only used in two or three 2026 weekends - could be very useful for next year.
Mercedes is going to run the major chassis upgrade it debuted at Sepang on both cars at Austin, having taken the unusual route of splitting specification between its cars last time out in Singapore.
That experiment taught Mercedes plenty during the Singapore weekend, and the debriefs the team has completed since that weekend have given it further clues as to how best to exploit the upgrade.
Both drivers will have the upgraded car right from FP1.
