We’ve discussed this many a time but I still don’t understand.
When Ricciardo replaced Karthikeyan, the engine usage obviously transfered from one to the other, so the engines Karthikeyan had used up were Ricciardo’s. Easy enough.
But with Karthikeyan now replacing Liuzzi for this round, he gets Liuzzi’s engines – therefore one driver could use all the 16? in one season in that way?
Could anyone make it clear once and for all? :)
