I guess we can just wait, then you can see what I am talking about. I am in Italy and live very close to the Fiorano factory. I know several people who work there. They have already made the chassis, but have to undergo crash tests again, don't know if it will be ready for the first race, but everything else is the same.
As far as the 25% downforce, maybe I didn't explain it too well. With the new positioning they reckon they can get 25% of what they could get with the blown diffuser, which would be enough to fix most of their problems.
Domenicali also said that the car has a very good performance over a single lap, confirming the good overall design , but by changing the exhaust to the new configuration, the lost downforce at the rear made the car less balanced, but the car is still fast, unbalanced but fast. The problem remains with tyre wear.

For you guys to write off ferrari, and put predictions like 10th on the grid, or lower, is just lack of objectivity, or wishful thinking.
