Following a difficult 2012 season in which the team finished fifth in the World Constructors' Championship despite recording their maiden victory at the Chinese Grand Prix, team principal Ross Brawn carried out an extensive array of changes to the team's engineering positions. Aldo Costa was recruited from Ferrari, as were Geoff Willis from the now-defunct HRT F1 Team and Mike Elliott from Lotus F1. Parallel to this, Mercedes's long-time Vice President of Motorsport Norbert Haug left the team; he was replaced by Toto Wolff, who left his role of Executive Director at Williams to take the position.
