勒克莱尔西班牙大奖赛无缘法拉利最新引擎规格
勒克莱尔因上周末意大利大奖赛在帕拉波利卡弯出口撞墙，无法在西班牙大奖赛使用法拉利最新的ADUO2引擎规格，只能使用ADUO1引擎，而汉密尔顿可正常使用ADUO2。
为什么查尔斯·勒克莱尔在西班牙大奖赛不使用最新的ADUO2引擎
法拉利在蒙扎引入了新的引擎规格，但勒克莱尔赛车上的动力单元在意大利大奖赛撞车后仍在接受检查
查尔斯·勒克莱尔仍能感受到上周末意大利大奖赛在帕拉波利卡弯出口撞墙的痛楚，而这次撞车的结果是，他将无法在西班牙大奖赛期间使用法拉利最新的F1引擎规格。
据了解，法拉利工程师认为配备FIA允许的第二套修改方案的067/6单元状态良好，但他们不想冒险在马德里环道运行它。
原因非常简单：F1规则禁止运行无法对其所有众多认证部件进行作业的引擎。在外部结构检查中未发现裂纹或断裂，但计划进行更彻底的X射线检查，以确定是否存在可能未被发现的微小损伤区域。
因此，不在西班牙首都冒险使用ADUO2引擎的决定是合乎逻辑的：马德里环道是新的，车手需要尽可能多地行驶，而工程师需要收集数据，以最终确定一个必须做出重大妥协的调校，以结合非常慢的路段和快速路段的需求。
顺便提一下，这座伊比利亚首都位于海拔667米处，与奥地利红牛环的海拔相似。因此，作为ADUO2套件一部分安装的更大的涡轮压缩机本可在略微稀薄的空气中提供性能提升。
勒克莱尔的赛车在蒙扎撞车中严重受损，引擎结构仍在接受彻底检查
周五练习中动力单元的任何小问题都可能危及大奖赛的准备工作，因此决定将受观察引擎的回归推迟到巴库的FP1。
因此，勒克莱尔将使用ADUO1引擎，而赛道工作人员将能够评估该单元与ADUO2之间的实际性能差异，刘易斯·汉密尔顿将能够正常使用ADUO2。
没有人谈论这件事，尤其是在蒙扎的尴尬之后，但车队内部有在马德里取得好成绩的雄心，因此仍有几个选项需要考虑。
这条赛道可能适合SF-26的特性：需要中高水平的空气动力学下压力，而沥青预计不会提供特别高的抓地力，这可能有利于那些在弯道出口具有出色牵引力的赛车。
下压力应该比效率更重要（我们可能会看到活动翼作动器上的额外襟翼再次出现），而法拉利受梅赛德斯V6动力不足的影响应该较小，因为有22个弯角，充电机会比蒙扎多得多。
汉密尔顿和勒克莱尔需要高度专注于单圈速度，因为在这条几乎不可能超车的赛道上，强劲的排位赛表现可能具有决定性。然而，如果事情没有按计划进行，摩纳哥人启用第二台ADUO2引擎（在池中可用）也并非不可能，这将导致他因引入本赛季第五台动力单元而受到首次处罚，但确保他有足够的储备以在没有进一步意外的情况下完成锦标赛。

Why Charles Leclerc isn't using latest ADUO2 engine in the Spanish GP
Ferrari introduced a new engine specification in Monza, but the power unit in Leclerc's car is still undergoing checks following his crash at the Italian GP
Charles Leclerc is still feeling the pain of smiting the wall at the exit of the Parabolica in last weekend's Italian Grand Prix, and the result of the crash is that he will not be able to use Ferrari's latest Formula 1 engine spec during the Spanish GP.
It's understood Ferrari engineers deemed the 067/6 unit, fitted with the second package of modifications permitted by the FIA, to be sound, but they did not want to take the risk of running it at the Madring.
The reason is very simple: F1 regulations prohibit running an engine that cannot be worked on in all of its many homologated components. No cracks or breakages were found during the external structural checks, but the intention is to carry out more thorough X-ray examinations to determine whether there are any small areas of damage that may have gone undetected.
The decision not to risk the ADUO2 engine in the Spanish capital is therefore a logical one: the Madring circuit is new and the drivers need to run for as long as possible, while the engineers need to gather data in order to finalise a setup that will have to be a significant compromise to combine the demands of very slow sections with those of the fast ones.
The Iberian capital, incidentally, is located 667 metres above sea level, an altitude similar to that of the Red Bull Ring in Austria. So the more substantial turbo compressor fitted as part of the ADUO2 package could have provided a performance gain in the slightly thinner air.
Leclerc's car was badly damaged by Monza crash and the engine's structure is still being thoroughly checked
Any small issues with the power unit during Friday practice could have risked compromising the preparation for the GP, hence the decision to postpone the return of the engine under observation until FP1 in Baku.
Leclerc, therefore, will have an ADUO1 engine at his disposal, while the trackside staff will be able to assess the actual performance difference between this unit and ADUO2, which Lewis Hamilton will be able to use as normal.
No one is talking about it, especially after the embarrassment at Monza, but within the Scuderia there is an ambition to perform well in Madrid, so there are still several options to consider.
The track could suit the characteristics of the SF-26: a medium-to-high level of aerodynamic downforce is required, and the asphalt is not expected to provide a particularly high level of grip, which could favour those with excellent traction on corner exit.
Downforce should matter more than efficiency (we may see the additional flaps on the actuators of the movable wings reappear), and the Ferrari should be less affected by the power deficit to the Mercedes V6 because there are 22 corners and the opportunities to recharge the battery are considerably greater than at Monza.
Hamilton and Leclerc will need to focus heavily on single-lap pace, because a strong qualifying performance on a circuit where overtaking will be almost impossible could prove decisive. If things do not go according to plan, however, it would not be out of the question for the Monegasque to put a second engine into service with ADUO2 (available in the pool), taking his first penalty for introducing a fifth power unit of the season, but ensuring that he has enough of a reserve to finish the championship without any further surprises.
