Most likely Alonso used his 8th engine for the third time in Korea. He should go back to his 2nd, 3rd or 7th on the next race (I strongly suspect he will go for the 7th on Interlagos and the 3rd on Abu Dhabi). Webber should still be alright but Hamilton and Vettel should be following Alonso’s way from now on.
Alonso has two engines left, one has done one race and the other two. Incredibly, he used engine #8 four times! Very risky from Ferrari.
Hamilton has three engines left, two have done two races and the other one.
Vettel only has one engine left, engine #8 blew up yesterday and engine #6 has done three races already. Engine # 7 has already done two though so he’s going to have to use one for a 4th time which I’d be very worried about.
@Icthyes I found an interesting thing from the site. All three teams which use Ferrari engine did 4 races per 1 engine. First Toro Rosso and then Sauber and Ferrari at the same time. and they have had no problem at all! Alonso even wins 3 of 4. I think Ferrari tested some protective engine management or collected data by using Toro Rosso and it seems like very successful.
but also Renault did 4 race per an engine one time(Kubica’s 5th engine). If Renault cooperate with Red bull, they will be OK. so I think engine reliability is not a serious issue. It’s just like some kind of luck. Like Vettel this time.
