Mercedes W12

The W12, whilst still highly competitive, was not as dominant as its predecessor either in pre-season testing or at the 2021 Bahrain Grand Prix. The regulation changes designed to reduce downforce produced by the floor area are said to have compromised lower rake designs, like the W12, more than higher rake designs like that of Red Bull RB16B, along with the banning of the DAS system.[3][4][5] Pundits Lawrence Barretto, Scott Mitchell, Mark Hughes and Edd Straw made Red Bull favourites for the first race of the year due to a stronger performance than Mercedes during testing.[6][7][8] Although Verstappen did beat the Mercedes cars of Hamilton (2nd) and Bottas (3rd) to pole at the season opener,[9] Hamilton narrowly won from Verstappen, with Bottas finishing third.[10] Williams driver and Mercedes protégé George Russell (who drove the W12's predecessor, the W11, at the 2020 Sakhir Grand Prix) suggested that the W12 and the Williams FW43B could have issues with wind sensitivity and could explain the struggles of Mercedes relative to Red Bull in Bahrain.[11]

However no rules were found by the FIA to be breached by Masi, to which safety car rules would be clarified for the 2022 season along with removing the single race director role. Mercedes appeals were rejected, giving Verstappen his maiden title and Hamilton staying on Seven world championships. Many fans believed Hamilton should have won his eighth title however many also argued other events such as the British GP, where Hamilton received a 10 second time penalty for taking Verstappen out of the race, should have been harsher towards Hamilton who still ended up winning the race, which would have effected the championship standings.
