2026款F1赛车在墨西哥为何异常之快
多重因素叠加，使2026款F1赛车在墨西哥的性能异常接近地效时代的前代赛车；勒克莱尔在第一节练习中跑出1分18秒128，首次让2026款赛车在第一节练习中快过2025款赛车。
多重因素叠加，使2026款F1赛车在墨西哥的性能异常接近地效时代的前代赛车。
勒克莱尔在第一节练习中跑出1分18秒128的最快圈速，比他在去年墨西哥站第一节练习中领跑时的圈速快0.252秒。这是2026款赛车首次在第一节练习中快过2025款赛车，此前它们通常要慢两到三秒。
勒克莱尔在第二节练习将标杆成绩提升0.3秒至1分17秒827，但仍比维斯塔潘去年的第二节练习基准慢0.435秒。
倍耐力赛前模拟曾预测杆位成绩为1分17秒0，但周五练习后，现在的预测将远低于这一数字。
去年的杆位成绩是1分15秒586，最终比FP2的速度快了1.8秒，因此可以预期2026年的杆位成绩会在1分16秒出头的区间。
这意味着2025年与2026年干地排位赛的差距将是本赛季最小的，此前最接近的一次是巴库的1.409秒。
那么，为什么2026年的赛车在墨西哥大奖赛上相对于地面效应时代的前辈们如此有竞争力？
这条赛道在2026年比赛前进行了部分重新铺设，重新铺设工作从10号弯一直延伸到1号弯。
倍耐力首席工程师西蒙内·贝拉表示：“这也可能是一个影响因素。”
“显然，部分路面经过了重新铺设，因此第一赛段和第二赛段的一半区域没有这种新沥青，所以这也可能是一个促成因素，但这并不是我们为何如此之快、或者说比预期更快的唯一解释。”
倍耐力提供的另一种解释是，赛道状况更好，因为今年有更多支援系列赛在赛道上留下了橡胶。
然而，与去年相比，第一次自由练习赛之前的赛道活动仅增加了10分钟，今年的支援赛事包括单一品牌GTM超级杯系列赛、大师历史赛和F4 NACAM锦标赛。
贝拉表示：“我认为这些成绩部分归因于赛道状况比去年更好，我们有多项垫场赛事在帮助改善赛道。”
“所有垫场赛事都在第一节练习赛之前以及第一节和第二节练习赛之间进行，因此赛道在一天中变化相当大。”
最重要的因素是墨西哥的高海拔对2026款赛车和动力单元性能的不利影响，比2025款套件更小。首先需要损失的总下压力就更少，而地面效应赛车对下压力的依赖程度更高。
贝拉说：“这里的条件和高海拔，相比旧款赛车更有利于这些赛车。”
与这一代赛车相比，旧款赛车损失的下压力更多。
另外一点是，与正常情况或海平面条件相比，引擎能输出更多动力。
所以这就是关键所在，车手可以全力推进，因此与去年圈速的差距被缩小了。
当然，海拔不会影响电力功率，而在2026款动力单元下，电力功率对性能的影响要大得多。
2026款赛车（勒克莱尔的红色圈速）在直道上比2025款赛车（维斯塔潘的蓝色圈速）更快，在通往4号左弯的路段上，2026款赛车快了超过0.4秒。而且需要指出的是，勒克莱尔的法拉利由于动力单元劣势，是前四车队中在这一路段最弱的赛车之一。因此，如果与维斯塔潘的2026款赛车相比，差距甚至更大。
2026款赛车在随后的低速弯中很快失去了积累的优势，并且再也无法恢复，但下降幅度远不如斯帕（2025与2026杆位之间相差3.799秒）和蒙扎（两者相差2.994秒）等其他赛道那么明显。
这些赛车在墨西哥实际上最终能量相对充裕，因此它是展示这些赛车性能的较好赛道之一。

A combination of factors means Formula 1's 2026 cars have been unusually close to the performance of their ground-effect predecessors in Mexico.
Charles Leclerc's FP1-topping time, a 1m18.128s, was 0.252s quicker than the lap he set to lead first practice in Mexico last year. That's the first time the 2026 cars have outpaced the 2025 cars in an FP1 session, having usually been two or three seconds slower.
Leclerc lowered the bar by three tenths to a 1m17.827s in FP2, though that was 0.435s slower than Max Verstappen's FP2 benchmark from last year.
Pirelli's pre-weekend simulations had predicted a 1m17.0s would be pole position, but after Friday's running it's now predicted to be well below that.
Pole position last year - a 1m15.586s - ended up being 1.8s faster than the pace in FP2, so you'd expect the 2026 pole position to be in the low-1m16s.
That should mean the smallest 2025 versus 2026 dry-weather qualifying difference of the season, with the previous closest being 1.409s in Baku.
So why are the 2026 cars so competitive at the Mexican Grand Prix relative to their ground-effect-era predecessors?
The track underwent a partial resurfacing ahead of the 2026 race, with resurfacing work taking place from Turn 10 to Turn 1.
"This could also be an effect," Pirelli's chief engineer Simone Berra said.
"Obviously it was partially resurfaced, so sector one and half of sector two didn't have this kind of new Tarmac, so that could be a contribution also, but it's not the only explanation about why we were so fast, or faster than we expected."
Another explanation Pirelli offered is the track being in better condition because there's more support series laying down rubber this year.
However, there has only been a 10-minute increase in the on-track action prior to FP1 versus last year, with the one-make GTM Super Copa series, Masters Historic and Formula 4 NACAM championship on the support bill this year.
"I think part of these results are due to the track in better conditions compared to last year, we have several supporting series that are helping," Berra said.
"All the supporting series run before FP1 and between FP1 and FP2, so the track was evolving quite a lot during the day."
The most important factor is Mexico's high altitude is also less detrimental to the performance of the 2026 cars and power units than the 2025 packages. There's less total downforce to lose in the first place and the ground-effect cars were more downforce-dependent.
"The conditions, the altitude here, it's in favour of these cars compared to the old one," Berra said.
"The old cars were losing more downforce, compared to what this car generation are losing.
"Also, the other point is that the engine can push more compared to a normal situation or sea level conditions.
"So that's the main point, the drivers can push and so the difference with laptimes from last year are reduced."
Altitude, of course, does not effect the electrical power, which is far more influential on performance with the 2026 power units.
The 2026 cars (Leclerc's lap in red) are quicker on the straights than the 2025 cars (Verstappen's lap in blue), with the 2026 machines over four tenths up on the run to the Turn 4 left-hander. And it should be noted that Leclerc's Ferrari is one of the weakest in this section among the top-four teams because of its power unit deficit. So the gap is even larger if you compare to Verstappen's 2026 car.
The 2026 cars quickly lose that built-up advantage in the low-speed corners that follow and never recover it, but the drop-off is far less stark than at other circuits such as Spa (3.799s between 2025 and 2026 poles) and Monza (2.994s between them).
The cars actually end up relatively energy-rich in Mexico, so it's one of the better tracks for showcasing the performance of these cars.
