A brief note to add to the comments Ferrari team principal Stefano Domenicali made about the new rules for penalties handed out for changing an engine during a Grand Prix weekend.
The rule now is that each driver has eight engines he can use during a season, but it’s up to him when he uses them.

The ten place drop will come if and when he needs to use a ninth engine in the season.
