A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

The reasoning behind that is in 2013, quite a few teams in fact had such a cascade.
Red Bull:

With the current era where noses are much lower, there is no need to get a Y250 vortex in the projected area. Infact it might be detrimental due disrupting flow going over the sidepods.

I don't know what the reasoning was behind the cascade.
You'll still get the Y250 vortex from the inside edges of the front wing. The extra addition will just serve to increase the strength of the vortex.

But it will also change the direction of the wing Y250 vortex (2 corotating vortices attract eachother).

For the matter: in my eyes you generate 2 Y250 vortices with such a cascade: one from the wing, and one from the cascade.

People love talking about the y250 vortex but you never go beyond the front wing where it is generated.
it would be more interesting if the discussion was about the function of the vortex as it makes its way downstream - I know it is different topic but just saying.

They both rotate the same way. Just the one from the r cascade starts in front helping the one coming off of the inside of the front wing.

From Autosport:

"Romain Grosjean will run a new Haas chassis on Tuesday's opening day of Formula 1's first in-season test of the year at Barcelona.

The Haas driver made an impressive start to the F1 season with sixth in Australia and fifth in Bahrain but has since struggled with the balance of the American team's VF-16."

"The Frenchman said during the Spanish Grand Prix weekend that the team had identified the problems but did not yet know how to solve them.

With two days of testing at Barcelona on Tuesday and Wednesday, Haas is using the opportunity to run a new chassis for Grosjean in a bid to find solutions.

"We've been struggling since China with something we don't quite yet understand so we're going to change everything for the test," said Grosjean.

"It's been hard for everyone because in terms of work everyone has been doing a great job of looking at the data and finding a solution - making the car on paper better - and we always underline that these are problems that Esteban doesn't have.

"It's quite strange that it's only happening in one car and that's why it's going to be very important for us at testing to change the chassis and put the set up in and see if things get better."

Grosjean said that Haas made changes on Friday night at Circuit de Catalunya, but they weren't as successful as hoped.

"We changed the philosophy of the set-up we'd made for China so this should bring the car back to where it was but actually it didn't happen as much as we wanted," he said.

"We went in a good direction that's why I'm saying that everyone has been working well.

"But under the table there's something that we don't see or understand.

"That's why we want to change the chassis to see if there's something weird in terms of torsion or something that's creating issues.""

Seems like quite a big wing for Monza.

Interesting one; not sure I've ever seen one exactly like that before. Maybe this is the closest:

Wouldn't you need to reduce the angle of attack at the endplates? As Mercedes have been doing in Spa.
I'd say this should reduce the downforce while moving straight, since the airbox is directly in front of the middle, and increase the downforce (compared to driving straight) during cornering.
