This year every full-time driver must give up their seat twice during a Friday practice session, as mandated by Article 1.7.3.c of the sporting regulations. The rule is designed to give 'rookies' real-world experience in F1 cars.

That means each team gives up four opportunities per season (two per car) and we have a host of changes to report for Friday's opening session at Autodromo Hermanos Rodriguez.
