Engine Unit Elements used by the 2017 F1 world championship drivers so far, ahead of round 17th – United States Grand Prix.
Recently McLaren ace Stoffel Vandoorne gets grid penalty after engine change. The Belgian youngster fitted 8th ICE of the season, now he equal with his McLaren teammate Fernando Alonso.
What the sporting regulations say:
Unless he drives for more than one team, each driver may use no more than four power units during a championship season. The only exception is where the power unit is provided by a manufacturer or supplier taking part in its first championship season, in which case up to five may be used by a driver.
Each driver is permitted to use only four of each of the above six elements during a championship season and any combination of them may be fitted to a car at any one time. Should a driver use more than four of any of the six power unit elements during the course of a season, a grid penalty will be imposed.
The penalties imposed for using additional elements work thus: the first time a fifth of any of the elements is used, a ten-place grid penalty will be imposed. A five-place grid penalty will then be imposed the first time a fifth of any of the remaining elements is used. Likewise, the first time a sixth of any of the elements is used, a ten-place grid penalty will be imposed, and so on.
During any single event, if a driver introduces more than one of a power unit element that is subject to a grid penalty, only the last element fitted may be used at subsequent events without further penalty.
If a driver is replaced at any time during the season his replacement will be deemed to be the original driver for the purposes of assessing power unit usage.
Teams may only use homologated power units.
