本田新F1引擎仍需改进的关键领域
本田今年首次ADUO升级的进展完全符合预期，不过这家日本厂商表示仍有一个领域需要努力：可驾驶性
在阿德里安·纽维为阿斯顿·马丁在匈牙利带来首个重大升级包之后，本田也在赞德沃特推出了本赛季F1的首次动力单元升级。
总工程师折原慎太郎解释说，这次升级完全集中在内燃机上，不过在赞德沃特，他带着一张纸来参加媒体会，以此强调他绝对不想谈论在马力或圈速方面的收益。
在蒙扎，折原已经不再随身携带那张纸了，这让他开玩笑说：“现在你们可以问我所有问题了！”
“在马力方面，本田仍然不愿意透露任何数字，尽管当Motorsport.com问及此事时，折原确实表示，这第一次ADUO升级的进展完全符合预期。
“所以我们曾在荷兰引入了一款新规格的引擎，我们观察到了性能上的一个进步，正如我们各项指标所预期的那样，”他说，“我们已经确认了在测试台架上看到的结果，所以这是我们在荷兰发现的一个积极因素。
不过，在赞德沃特的比赛周末也表明，仍然有工作需要完成。
“另一方面，我们在驾驶感受方面发现了一些可以改进的地方。因此我们更新了燃烧特性，然后准备了数据设置和工具来适应这些新的燃烧特性，以获得更好的驾驶感受。”折原继续说道。
“但这还不足以让车手们满意。所以这绝对是我们在荷兰站发现的改进点。”
本田的折原慎太郎在接受Motorsport.com罗纳德·沃尔丁的采访时说道。
驾驶感受指的是车手从动力单元获得的感觉。这种感觉尚未完全达到本田的预期，也未能在一整圈中保持完全一致，这并不令人意外。
折原已经在斯帕-弗朗科尔尚赛道接受Motorsport.赛车运动网独家采访时提前透露了这一点，这意味着本田知道，在将第一套ADUO升级件带上赛道之后，仍然有工作要做。其中一些工作已经在赞德沃特赛后的十天里完成了。
“我们把所有数据带回了测试台架，我们也把所有车手的反馈带回了测试台架，”折原继续说道。“他们在HRC樱和研发中心进行了一些测试，以改进我们的控制系统，从而获得更好的可驾驶性。所以本周末的主要重点将是在蒙扎赛道确认这些应对措施。”
当被问及可驾驶性问题具体是什么时，这位本田一级方程式项目的总工程师解释说，这是一个涉及多个不同方面的复杂问题。
“如果说到可驾驶性，它包含换挡、制动阶段的燃烧稳定性，还有发动机反拖（引擎制动）阶段的燃烧稳定性以及扭矩响应，”折原详细说明道。“很多因素共同构成了可驾驶性，我们需要改善整个领域。”
“所以主要问题在于我们如何控制燃烧，以及如何获得稳定的燃烧。这是提升我们整体可驾驶性的主要着力点。”
虽然本田主要是在寻求新燃烧特性下的稳定性，但阿斯顿·马丁的赛道事务负责人迈克·克拉ック强调，可驾驶性也与底盘有关。
“可驾驶性不仅是动力单元的问题，也是底盘的问题，所以我们需要在这方面协同工作，努力弄清所有事情，”克拉克说。
“你想要追求最优，但同时也希望在不同程度的能量回收、不同程度的制动以及不同程度的降挡下都能保持一致。这可不是一件容易的事。”
“我认为这是每支车队都在学习的东西，而且每支车队确实都必须针对赛道的每一段进行优化。归根结底，在谈到可驾驶性时，我们不能只看动力单元，还要看整体。底盘和动力单元的所有部件都牵涉其中。”
随着这些方面的改善，本田认为还能从赞德沃特的升级中再榨取一点性能，不过这不会是一个大的进步，因为不会再有新的硬件改动。
“尽管如此，我们认为通过优化数据，我们还有提升性能的空间。”折原说。“我们为这条赛道带来了一些标定方面的改动，以最大化我们的性能，但这不会是一个大的变化，只是优化而已。”

The key area Honda still needs to improve with its new F1 engine
Progress with Honda’s first ADUO upgrade of the year is fully in line with expectations, although the Japanese manufacturer says there is still one area it needs to work on: driveability
After Adrian Newey’s first major upgrade package in Hungary for Aston Martin, Honda introduced its first power unit update of the Formula 1 season in Zandvoort.
Chief engineer Shintaro Orihara explained that the upgrade was entirely focused on the internal combustion engine, although in Zandvoort he brought a piece of paper with him to his media session to stress that he absolutely did not want to talk about the gains in terms of horsepower or lap time.
In Monza, Orihara no longer has that piece of paper with him, which prompted him to joke: “Now you can ask me everything!”
Honda still does not want to disclose any numbers when it comes to horsepower, although Orihara did say the progress with this first ADUO upgrade is fully in line with expectations, when asked about it by Motorsport.com.
“So we introduced a new spec engine in the Netherlands and we have observed a step forward in terms of performance, as expected in our metrics,” he said. “We have confirmed what we saw on the dyno, so that was a positive thing that we found in the Netherlands.”
However, the race weekend in Zandvoort also showed that there still was work to be done.
“On the other hand, we found some things to improve in terms of driveability. So we have updated our combustion characteristics and then we prepared the data settings and the tools to adapt to these new combustion characteristics to get better drievability,” Orihara continued.
“But it was not enough to satisfy the drivers. So that is definitely our improvement point that we found in the Netherlands.”

Driveability refers to the feeling drivers get from the power unit. The fact that this feeling is not yet entirely where Honda wants it to be, nor fully consistent throughout the lap, does not come as a surprise.
Orihara had already flagged this at Spa-Francorchamps in an exclusive interview with Motorsport.com, meaning Honda knew it still had work to do after bringing its first ADUO upgrade to the track. Some of that work has already been carried out in the 10 days since Zandvoort.
“We brought back all data to the dyno and we brought back all driver feedback to the dyno,” Orihara continued. “They have carried out some testing in HRC Sakura to improve our controls to get better driveability. So the main focus point for this weekend will be to confirm those countermeasures in Monza.”
Asked exactly what the driveability issues are, Honda’s chief engineer for the F1 project explained that it was a complex picture involving several different aspects.
“If you say driveability, that contains the shifting and the combustion stability during the braking phase, and also during the engine braking phase and torque pickup,” Orihara detailed. “A lot of things combine into driveability and we need to improve the full area.
“So the main issue is how we control our combustion and how we get stable combustion. That is the main focus point to improve our full driveability.”
While Honda is primarily looking for stability with the new combustion characteristics, Aston Martin chief trackside officer Mike Krack stressed that driveability was also linked to the chassis.
“Driveability is not only a PU topic, driveability is also a chassis topic, so we need to work together on this, trying to understand everything,” Krack said.
“You want to go for the optimum, but also you want to be consistent with different levels of regen, with different levels of braking, and with different levels of downshifting. It's not an easy exercise.
“I think it's something that every team is learning and that every team really has to optimize for each section of the track. At the end of the day, when speaking about driveability, we must not only look at the PU but also at the whole thing. All the elements of the chassis and the PU are involved.”
As these aspects improve, Honda believes it can also extract a little more performance from the Zandvoort upgrade, although this will not amount to a major step as there will be no further hardware changes.
“Still, we think we have some room to improve performance by optimizing the data,” Orihara said. “We have brought some calibration changes for this track to maximize our performance, but it's not going to be a big change, just optimizing.”
