Sauber C31 Ferrari

Actually I think that section has been broken in transit or from pitstop practice?

Yes, it was probably broken in the picture I posted earlier. I thought that it looked kind of funky the first time I saw it, but now it makes sense - that whole part had a strange shape.

Yas Marina testing: Day 1

[Huntresa]

Nice one from Sauber doing 2013 stuff.

nice small cooling hole on the floor, at the red line

I like the additional tube in the Passive DRS system being fed into what looks like the center of the beam wing. Blowing a slot perhaps?

[Morteza]

Looks better than Mercedes passive DDRS system. Very neat

Yas Marina testing: Day 2








Edit 1&2.: adding more photos from today

I don't get how the passive DRS works, and what's with the passive DRS pipe not connecting to the rear wing why is it not connected?

I would massively appreciate it if someone could explain or PM me.

Difference of various theories. Some like to blow the top wing, others like to blow the beam wing. It looks as if Sauber are trying the alternatives to see which gives the best results.

Where are the intakes for air on the Sauber system? It's not exactly the same as the Lotus "ears", but I can't tell if it's underneath the roll hoop.

It couldn't be those tiny things on the nose could it? That would require a lot more piping and seem a bit counter-intuitive.

[Intego]

I also think the slots in front of the driver are the intakes as they are removed when the DRD is unmounted. Probably that's the position where the least drag is emerged.
