Carlos Sainz will start the Turkish Grand Prix from the back of the grid after Ferrari confirmed his car will be fitted with a brand-new power unit for this weekend's race.
The move means the Spaniard will follow in the footsteps of teammate Charles Leclerc, who took a new engine featuring the team's updated hybrid system in Russia.
"As was the case for Charles Leclerc in Russia, in Turkey Carlos Sainz will take a completely new power unit fitted with the new hybrid system," read a statement from Ferrari.
"Therefore he will start from the back of the grid with the aim of climbing up the order to try and score some points."
Leclerc was complimentary of the new engine following Friday practice in Sochi, stating that the data confirmed there was an improvement in performance.
"I feel that it is a little bit better, which is great," Leclerc told Formula1.com. "And obviously the data confirms it, so yes, it's great to feel it and to see it."
The news means Sainz will have his work cut out for him if he is to repeat his performance in Russia, when he finished the race in P3 – his third podium of the season.
Ferrari also announced that Mattia Binotto will not attend the Turkish Grand Prix, as he remains at the Maranello factory to focus on development of the 2022 F1 car. Binotto will nonetheless supervise operations from the team's Remote Garage.
Lewis Hamilton claimed his 100th Grand Prix win to move into the championship lead, but it's Red Bull and Max Verstappen who will be happiest after the Russian Grand Prix.
