Sauber C32 Ferrari

[turbof1]

This is better then an undercut: no bodywork at all. Air can now freely flow to the back, almost unhindered.

The step in laminar flow from the sidepod top to the exhaust system concerns me. Mclaren started their system somewhat like this last year but ultimately found as we can see with late 27 and now 28 that the transition of flow to the exhaust is about seemless ie. no step. It can also clearly be seen in the new Ferrari that the flow transition to the exhaust is minus any brakes.

The new Sauber's sidepods opted for what is essentially no undercut around the sidepods/floor area which causes that area to be slightly larger, and this packaging is probably why they could not further tighten the sidepod transition to the exhaust. I actually believe the exhaust almost looks like an afterthought with the way everything else around it is designed.

Sharp looking car otherwise.

I thought the same thing initially, but the sidepod is much tighter up top compared to how the Mclaren started last year. I think they may get more air flow to the exhaust now because nothing is there. The vortex off the flow conditioner wing goes straight to the exhaust, it doesn't have to travel along a sidepod. It's interesting to see this because last year's car had a very nice flowing ramp to the exhaust.

"Checo had quite a bad accident in Monaco a few years ago and when we got the car back and we saw the sidepod all squashed in, we thought 'I wonder if we could do that?'"

"The sidepods are a bold move, a bold design, but we are pretty confident.

"One of the huge challenges for us is in packaging all of the radiators and boxes. Like most things in Switzerland, we got it just in time!"

"We have a whole new braking system that we were developing last year," said Morris.

"In terms of the chassis, this is an area we've spent a lot of time and effort on to save weight. We've made some savings without compromising safety.

"The exhaust is not massively different to what we finished with last year, we just further enhanced it.

"The front wing is predominantly a carry-over from last year.

"One of the small regulation changes is an additional legality check on the front wing, so we've had to spend a lot of time changing the structure of the wing to be sure we pass that.

"That's something we spent a lot of time over the winter developing."

"Passive DRS is allowed, so this is an area that we're looking at developing through the course of winter testing," he said.

Nice sidepods hehe

I always thought Sauber do a good job with limited reasources. I think this car is the most radical of the ones presented. Not having undercut pods to the floor is really special in my mind, wonder what the thinking is with this. Clearly it´s going to be big hit or a big fail because i think it´s quite substanial change.

What is sure is that the car will have lower c.o.g, wonder if that was main purpose of the design or if there is some nica aero trick no one else have thought of.

The sidepods join the floor where others have an undercut. The top part is squished in so tight that it does away with the undercut.

Dat sidepod

Especially impressive considering the C32 shot there is more zoomed in. Just comparing the gaps to those sideburn turning vanes shows how drastic this is.

I would be extremly impressed if this was the case so im sure it´s not. Other teams would have done the same if it was possible without compromise. It hink it´s just a diffrent way of distributing the components and they have placed more lower down.

To be clear, here's where I'm guessing their intended air flow is going:

The picture above is very interesting for me. as mclaren, also sauber have this year increased the size of the sidepod intake. In the mp4-28 I supposed it was related to a change in radiators position; sauber have indeed stated that they have made such a change.
The sidepod panels juction in sideview gives a rough estimate of their new position: inclined and forward.

It is a significant change: for years we were used to teams that year by year struggled to get smaller and smaller openings to minimise internal losses - now two of the teams with best aero resources go in the opposite direction.

Also worth noting that sauber last year shared with ferrari the unconventional vertical rad position and have for this year decided to change it

Nice comparison. It looks like new sidepods are a bit wider at bottom and of course have fully revised cooling air inlets.

[Sevach]

Instead of undercut Sauber has an "overcut" very cool idea.

[Owen.C93]

They've moved some cooling to the roll hoop like McLaren which will help a bit. Most likely gearbox but could be KERS.

Yeah that's insane how slim they've made them when you use the sidepod vanes to compare to other cars.

Not instead of, as well as
