劳森因技术违规被取消墨西哥站排位成绩
利亚姆·劳森因MGU-K降速速率技术违规被取消墨西哥城大奖赛排位赛成绩，失去第九位发车位置。
利亚姆·劳森被取消墨西哥站F1排位赛成绩——原因如下
劳森因技术违规被排除在排位赛成绩之外。该问题涉及他在Q2完成最快圈后的MGU-K降速速率。
利亚姆·劳森失去了F1墨西哥城大奖赛第九位的发车位置。
小红牛周六在罗德里格斯兄弟赛道表现出色，两辆赛车均闯入Q3。车队随后以第八和第九位成为其余车队中的最佳，但劳森现在要在周日正赛中追赶。
这位新西兰车手因技术违规被国际汽联取消资格。传唤文件中已经写明：“劳森在Q2最快圈过线后不久，于15:47:36违反了MGU-K最低功率要求。”
在前往干事处后，结果与几乎所有技术违规相同：取消资格。实际上，劳森在完成Q2最快圈后没有立即松开油门，这意味着他未能遵守规定的MGU-K降功率速率。
根据技术规则第C5.12.6条，该电功率必须逐渐降低。该条规定每秒最大降低50或100千瓦：
“当ERS-K的直流电功率高于100千瓦时，车手最大功率需求的降低速率不得超过以下定义值：
a. 在国际汽联认定功率受限距离超过3500米的比赛中，任意1秒周期内为50千瓦。用于计算功率受限距离的车辆基础数据可在文件FIA-F1-DOC-034中查阅。
b. 在所有其他比赛中，任意1秒周期内为100千瓦。”
在劳森的情况下，正如赛事干事报告所述，他在越过终点线后未能立即松开油门，因此电功率的下降速率更为陡峭。
“提交的证据（所有在场各方均予接受）显示，在他Q2最快圈结束后的控制线之后，该车手并未立即松开动力。这导致实现规定‘降档’所需的MGU-K部署降低速率未能达成。”
传唤文件进一步说明了这一违规行为如下：“车手的最大功率需求和 ERS-K 的直流电功率以高于规则允许的速率被降低。”
在听证会上，各方均认定小红牛（小红牛）未从该违规中获得任何竞技优势，尽管这一认定不足以避免取消资格。毕竟，技术违规始终是非黑即白的。
“车队辩称这并未提供任何性能优势，但很明显，即使未获得性能优势，也不能免除不遵守技术规则的责任。此外，这些规则要求赛车在赛事期间必须始终符合规则。”
“干事特别指出，车队自行披露了违规行为，但有许多先例要求我们，尽管存在所有减轻情节，在赛车不符合技术规则时仍必须处以取消资格的处罚。”
这意味着劳森在周日将不得不从发车格最后一位起步，并面临一路超车追赶的局面。这次取消资格对阿尔派来说是好消息，其争夺车队积分榜第五名的对手之一如今被迫从最后一位起步。不过在积分榜上，小红牛仍以33分的优势稳居前列。

Liam Lawson disqualified from F1 qualifying in Mexico – here's why
Lawson has been excluded from the qualifying results due to a technical infringement. It concerns the MGU-K rampdown rate after he completed his fastest lap in Q2
Liam Lawson has lost his ninth-place starting position for the Formula 1 Mexico City Grand Prix.
Racing Bulls impressed at the Autodromo Hermanos Rodriguez on Saturday and managed to get both cars into Q3. The team subsequently emerged as the 'best of the rest' in eighth and ninth places, but Lawson now faces a recovery drive on Sunday.
The New Zealander has been disqualified by the FIA for a technical infringement. The summons document had already stated that “Lawson was in breach of the minimum MGU-K power requirement just after crossing the line on his fastest lap in Q2 at 15:47:36.”
Following a visit to the stewards, the outcome was the same as for almost all technical infringements: disqualification. In practice, Lawson did not immediately lift off the throttle after completing his fastest Q2 lap, meaning he failed to comply with the prescribed MGU-K rampdown rate.
That electrical power must be reduced gradually in accordance with Article C5.12.6 of the technical regulations. It stipulates maximum reductions of either 50 or 100kW per second:
“The driver maximum power demand must not be reduced at any greater than the rates defined below whilst the electrical DC power of the ERS-K is above 100kW:
a. 50kW in any 1s period at Competitions where the FIA determines that the power limited distance exceeds 3500m. The vehicle fundamentals used for the calculation of the power limited distance may be found in the document FIA-F1-DOC-034.
b. 100kW in any 1s period at all other Competitions.”
In Lawson's case, that rampdown rate of the electrical power was steeper after he failed to lift off the throttle immediately upon crossing the line, as described in the stewards' report.
“Evidence submitted, which was accepted by all parties present, showed that after the control line at the end of his fastest lap in Q2, the driver did not lift off the power immediately. This resulted in the rate of reduction of MGU-K deployment required to achieve the regulated “step down”, not being achieved.”
The summons document further clarified this breach as follows: “The driver maximum power demand and the electrical DC power of the ERS-K were reduced at greater rates than what is permitted by the Regulations.”
During the hearing, all parties concluded that Racing Bulls had gained no sporting advantage from the infringement, although that finding was not enough to prevent the disqualification. Technical infringements are, after all, always black and white.
“The team argued that this did not provide any performance advantage however it is clear that non-compliance with the Technical Regulations is not excused if no performance advantage is gained. Further, these regulations require that a car must comply with them at all times during an event.
“The Stewards note in particular that the team self-disclosed the breach however there are a multitude of precedents that require us, despite all mitigating circumstances, to impose a penalty of Disqualfication where a car does not comply with the Technical Regulations.”
It means Lawson will have to start from the very back of the grid on Sunday and faces a fight through the field. The disqualification is good news for Alpine, with one of its rivals for fifth place in the constructors' championship now forced to start from the back. In the standings, however, Racing Bulls still holds a comfortable 33-point advantage.
