The centre of gravity seems too high. The driver position is compromised for the aerodynamics around the front. At least that's what i guess from the way the F150 is moving
I think this car is built for high speed tracks. But when things slow down the high COG has a bigger effect on handling.
Alonso is fighting the car, i don't think it should even be in fifht place on a track like melbourne.
This is just the begining though. This car is still up there in terms of pace, maybe they're just not having a good weekend; though race pace is a whole other story.
