explain please ??
Engine nº8, used in india and qualy.
If RB install a new engine, the nº9, then
"e) If an engine is changed in accordance with Article 34.1 (parc fermé) the engine which was replaced may not be used during any future qualifying session or race with the exception of the last Event of the Championship"
So engine number 8, only will be used in Brazil.
IND (n 8.1) ABD (n 9.1) USA (N 9.2) BRZ ( n 8.2)
But Brazil is at high altitude.
Vettel can be retired on Abu Dhabi.. and damage a new engine.
Redbull may opted for other option:
conservative: IND (n 8.1) ABD (n 8.2) USA (N 8.3) and BRZ ( n 9.1) (pole an 10 places for a new engine?)
Normal: IND (n 8.1) ABD (n 8.2) USA (N 9.1) and BRZ ( n 8.3) (championship decided)
OR
defensive: IND (n 8.1) ABD (n 8.2) USA (N 9.1) and BRZ ( n 9.2) (championship to decide on last race)
Ferrari..
IND (n 7.3) ABD (n 8.1) USA (N8.2) BRZ ( n5.1 - Spa engine, not used in race.. )
