The major car upgrade Mercedes bring in at this weekend’s Monaco Grand Prix will not be a “silver bullet”, team principal Toto Wolff says. Monaco will “provide an opportunity to learn about the upgrades,” Wolff said. While Monaco is not normally a track where a team would choose to introduce a major design revision, Mercedes decided to press ahead because the cars had already been modified for Imola. In the constructors’ championship, they trail Red Bull and Aston Martin, who buy their engines and much of the rear end of their car from Mercedes. In qualifying, the Mercedes has been on average the fourth-quickest car over one lap this season, behind Red Bull, Ferrari and Aston Martin.
