Yuki Tsunoda's AlphaTauri has been completely changed after the team fitted a brand-new power unit onto the car overnight in Imola.
Tsunoda crashed at the final chicane in qualifying, hitting the barriers hard. AlphaTauri have opted to change the internal combustion engine, turbocharger, MGU-K, MGU-H, energy store and control electronics as well as a new exhaust.
It's the rookie's third energy store and control electronics of the season after he had a problem on Friday during the opening practice session which limited him to just 11 laps
AlphaTauri have also changed the gearbox on Tsunoda's car and may decide to start him from the pitlane rather than 20th place on the grid.
