Lando Norris is set to start the Sakhir Grand Prix from the back of the field after McLaren opted to install new power unit components ahead of the race.
A fourth internal combustion engine and turbocharger has been fitted to Norris’ car overnight, exceeding the quota of three elements that can be used penalty-free during the year.
Norris endured a difficult qualifying session on Saturday, dropping out in Q2 as the slowest driver on the timesheet.
However, he will now drop further back, joining Pietro Fittipaldi on the last row of the grid, who also received a penalty due to power unit changes.
Haas’ Kevin Magnussen, as well as the Williams duo of Nicholas Latifi and Jack Aitken, will move up one spot each as a result of Norris’ penalty.
McLaren is currently in a close battle for third in the Championship, heading rivals Racing Point by 17 points with just two races remaining in the 2020 season.
Norris’ team-mate Carlos Sainz will line-up in eighth place for the start of Sunday’s race in Bahrain.
