本田秘密在马德里引入第二个F1 ADUO升级
本田赛车公司（HRC）透露，本田本赛季F1的第二个ADUO升级是新的涡轮增压器，早在西班牙大奖赛就已引入。
本田赛车公司社长渡边浩司透露，本田实际上早在F1西班牙大奖赛就引入了第二个额外开发与升级机会升级，重点针对动力单元的涡轮增压器。
阿斯顿·马丁和本田从赛季开始时表现挣扎，但在亨格罗林引入重大底盘升级后表现略有改善。在赞德沃特，车队还引入了搭载第一个ADUO升级的动力单元。
据测量，本田的内燃机（ICE）比红牛福特动力总成的引擎落后超过4%，后者被评为输出功率最高的引擎，这意味着本田获准在赛季中使用两个空气动力学升级配额令牌。
本田和HRC此前曾解释说，他们只会使用其中一次ADUO机会。“我们两次都用了，”渡边在接受Motorsport.com网站采访时透露，当时他被问到为什么本田决定只使用一次ADUO升级。
“我们在荷兰引入了第一次ADUO升级，然后在西班牙大奖赛上，我们把一套包含第二次升级的动力单元装到了斯特罗尔的车上。
“我们在荷兰引入的2号规格动力单元存在一些可驾驶性问题，所以我们在西班牙大奖赛上引入了一个改进版的涡轮增压器。”
事实上，国际汽联的动力单元部件使用清单显示，斯特罗尔的赛车在西班牙大奖赛时已经用上了本赛季的第五个涡轮增压器。费尔南多·阿隆索的赛车也在阿塞拜疆大奖赛装上了第五个涡轮增压器，而这看起来就是升级版本。
当被问及目标是否是解决涡轮迟滞问题时，渡边回答说：“是的。”他随后解释了分阶段引入升级部件的思路。
“如果我们能一次性把所有东西都引入当然更好，但首先在荷兰引入规格2（Spec 2）非常重要。与此同时，我们也在研究解决涡轮迟滞的对策，所以在西班牙引入了这部分。
“因此，应用最终被分成了两部分。”
不过渡边也表示，本田仍未完全发挥其动力单元的全部潜力。
本田此前为红牛供应引擎时，不被允许引入性能升级，但仍继续利用模拟来确定动力单元的运行极限，并逐年逐步提高这些极限。这就是本田所说的“可靠性研发”。
例如，红牛在2024年采用了极其窄小的侧箱，同时也缩小了用于引入冷却气流的开口尺寸。这也得益于提高动力单元的运行极限才得以实现。
“就ADUO而言，我们已经用完了本赛季的升级机会。从这里开始，我们将继续在不涉及硬件的方面下功夫，同时也进行面向未来发展的研发。”渡边说道。
我认为我们距离完全发挥这套动力单元的全部性能还很远。我相信它的竞争力仍有提升空间。
此前仍有一些地方存在动力不足，因此我们带着明确的目标数值开发了第二版规格。我们已经达成了这些目标，所以在赛季剩余的时间里，我们的重点将放在充分利用现有成果上，而不是继续开发硬件。
即便如此，我们仍要确保自己能够真正地进行竞争。

Honda secretly introduced second F1 ADUO upgrade in Madrid
Honda's second ADUO upgrade of the F1 season was a new turbocharger, already introduced at the Spanish Grand Prix, HRC reveals
Honda Racing Corporation president Koji Watanabe has revealed that Honda actually introduced its second ADUO (Additional Development and Upgrade Opportunities) upgrade as early as Formula 1’s Spanish Grand Prix, with the upgrade focused on the power unit's turbocharger.
Aston Martin and Honda struggled from the start of the season, but their performance slightly improved after a major chassis upgrade was introduced at the Hungaroring. In Zandvoort, the team also introduced a power unit fitted with the first ADUO upgrade.
Honda's ICE was measured to be more than 4% behind the Red Bull Ford Powertrains engine, which was rated as having the highest output, meaning Honda was granted permission to use two ADUO tokens during the season.
Honda and HRC had previously explained that they would use only one of those ADUO opportunities. “We used both of them,” Watanabe revealed to Motorsport.com when asked why Honda had decided to use only one ADUO upgrade.
“We introduced the first ADUO upgrade in the Netherlands, and then we put a PU incorporating the second update into Lance Stroll's car at the Spanish Grand Prix.
“The Spec 2 PU we introduced in the Netherlands had some drivability issues, so we introduced an improved turbo at the Spanish Grand Prix.”
Indeed, the FIA's list of PU component usage shows that Stroll's car was fitted with its fifth turbocharger of the season at the Spanish GP. Fernando Alonso's car was also fitted with his fifth turbo, which would appear to be the upgraded version, at the Azerbaijan GP.
Asked whether the objective was to address turbo lag, Watanabe replied: “Yes.” He subsequently explained the thinking behind the staggered introduction of the upgrades.
“It would have been better if we could have introduced everything at once, but it was important to introduce Spec 2 in the Netherlands first. We were also working on measures to address the turbo lag in parallel, so we introduced that in Spain.
“So the application ended up being split between the two.”
Watanabe also said, however, that Honda is still not extracting the full potential of its power unit.
When Honda was previously supplying Red Bull, it was not allowed to introduce performance upgrades, but it continued to use simulations to determine the operating limits of the PU and gradually raise those limits year after year. This was what Honda referred to as “reliability development”.
For example, Red Bull adopted extremely small sidepods in 2024, while also reducing the size of the openings used to draw in airflow for cooling. This was also made possible by raising the PU's operating limits.
“As far as ADUO is concerned, we have used up our opportunities for this season. From here, we will continue working on things that don't involve hardware, as well as developments that will lead into the future”, Watanabe said.
“I don't think we are anywhere near extracting the full performance of the PU. I believe there is still room to improve its competitiveness.
“There were still areas where we were lacking power, so we developed Spec 2 with target figures in mind. We have achieved those targets, so for the remainder of the season, our focus will be on making full use of what we have, rather than continuing to develop the hardware.
“Even so, we want to make sure we are able to fight properly.”
