Rough for George, having his new engine bonk the wall already. No surprise on a monza engine swap with 8 to go after.
It probably wasn’t that powertrain in the car for FP1. Usually the new engine makes in the car by FP3 or even quali. Even on normal weekends without a new engine, and especially later in the season, teams would run an “FP1 engine” on Friday to minimize mileage on a different engine for the more demanding circuits.
On F1TV they reported it was the new PU fitted but it could be wrong. I was very surprised to hear it, usually the wait till Saturday
I remember they mentioned kimi had the new Floor fitted on the car. I don’t remember them mentioning the PU
