So how it is now with penalties for Mclaren.
2017 F1 Sporting Regulations 16/74 24 January 2017
©2017 Fédération Internationale de l’Automobile wrote:For the purposes of this Article 23.3, the power unit will be deemed to comprise six separate elements, the engine (ICE), the motor generator unit-kinetic (MGU-K), the
motor generator unit-heat (MGU-H), the energy store (ES), turbocharger (TC) and
control electronics (CE).
Each driver will therefore be permitted to use four of each of the above six components
during a Championship season and any combination of them may be fitted to a car at
any one time.
e) Should a driver use more than four of any one of the elements during a Championship
season, a grid place penalty will be imposed upon him at the first Event during which
each additional element is used. Penalties will be applied according to the following
table and will be cumulative :
The first time a 5th of any of the Ten grid place penalty.
elements is used.
The first time a 5th of any of the Five grid place penalty.
remaining elements is used.
The first time a 6th of any of the Ten grid place penalty.
elements is used.
The first time a 6th of any of the Five grid place penalty.
remaining elements is used, and so on.
A power unit or any of the six elements will be deemed to have been used once the
car’s timing transponder has shown that it has left the pit lane.
During any single Event, if a driver introduces more than one of the same power unit
element which is subject to penalties, only the last element fitted may be used at
subsequent Events without further penalty.
If understand correctly. Yo got failed 2 failed compoments. For example CE in MGUK . So 2×10 places=-20 places. And you had another MGUK fail and you had obligation to run MGUK#2 part onwards throw event. Even more you got more running, got another failure and you need another MGUK#3 and so you are again obliged to use last one. So that means that you cannot use part MGUK#1 in MGUK#2 in current weekend, but could you use at the next weekend? Or next weekend you got another penalty for "second first" use of #2 element? So no free elements to stack it on on another in one event.
