Lewis Hamilton and Charles Leclerc hit with Sao Paulo grid penalties in more Ferrari misery

The Ferrari duo have both changed their engines for the first time this season and as such have been hit with the penalty by the FIA. But Hamilton immediately hit trouble in final practice. First he complained of vibrations from his new engine before having to come in again with his car pouring smoke from the back. The pair held showdown talks with boss Fred Vasseur on Thursday evening after Hamilton's fury over his team-mate's lap-one overtake on him in Mexico. Hamilton questioned Leclerc's mentality and vowed not to be silenced at Ferrari as he arrived in Brazil.
