Lewis Hamilton raised attention after the Formula 1 Belgian Grand Prix when he said he had "a change of engineer" at Ferrari, who has been revealed to be Johannes Hatz, son of former Porsche executive Wolfgang Hatz.
The seven-time F1 world champion’s comment "we were both in a deep end" about a new engineer after the Spa race provoked intrigue given there was no announcement of a change on Hamilton’s side of the garage by Ferrari.
