The problem may be the wings. They seem a bit 2009. Not only that but it may well be the setup of the car.
Remember williams use to be friday practice pole position queens with Nico Rosberg?
They used to run the car very light in practice.
So their approach to setting up the car with the pirellis and fuel may be wrong, similar to mercedes who just now realized they were taking the wrong approach fuel weight wise with learning the tyres.
Wings and practice procedure. The skirted diffuser is the other thing, but isn't a fundamental problem.
You're wrong I'm afraid.
Traction is said to be very poor, due to the Cosworth driveability, so the rear tyres go off early.
DRS flap is too big, so they lose performance in Qualifying.
They have quite alot of rear downforce, but they don't have a front end to match it, hopefully the new front wing that is coming for Turkey will solve that.
