Williams FW47

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

Pushrod at rear so presumably the updated mercedes rear suspension. But we can't know yet if it's 2024 or 2025 Merc spec

Autoracer reports it
On the FW47, the rear push rod was confirmed and the front push rod remains

To me, it looks similar to what the FW45 had 2 years ago:

Looks much more "normal" on the images shared by Vanja a couple of replies earlier. The shadows play some trickery on the closeups.
It looks more normal for sure, but the bump is still a whole lot more pronounced than I've seen previously. The SIS looks like it has been placed a lot higher than in previous years. In hindsight I realized McLaren also seems to have a really big SIS bump on the MCL39.

If it isn't placed that high primarily to generate outwash it surely must serve some other purpose under the floor. It's definitely a whole lot larger than on the FW45.

Is think the SIS position is all about bring it is as low (inside the floor) as possible without beeing a problem if the floor roof becomes higher in future development.

So, after looking throgh a lot of pictures and reading everything I could find, The car looks to be an agressive evolution of FW46.
It has an entirely new nose cone and front wing, similar to the McLaren and RB cars.
Front brake ducts are smaller, even tho the inlets are about the same, but the outlets are smaller and more complex (I cant find the picture where I saw that).
Front suspension is still pushrod, but it has new geometry, more agresive antidive. there is no new halo aero.
Engine cover is lower (shorter behind the airbox) and narrover (it is streight at the Gulf logo, and not buldged out).
I didn't see any good pictures of the watterslides, but I asume that they are there, the air to them should be less disturbed, becouse the line around the headrest is streighter than last year.
Udercut is huge, and it even turns upwards, the line where the floor mits the chassis is smoother and less disruptive. Floor edger look to be more comlex.
It has 2025 Mercedes rear end with push rod suspension.
The high downforce rear wing I think is the same as last year, but the low DF one is new, with detached edges of the upper plane at the endplate.
The color looks good, I hope that the official racing livery is even better.

Edit: Front suspension is pushrod, not pullrod as I stated earlier #-o

Looking to push a bigger vortex off the cut at top? Probably works alongside the undercut-undercut? A novel approach & something that we haven’t seen in this regulation set before, also makes sense that it ties-in with the new front flap profile.

Interesting that from your initial analysis that is looks like they are trying to shave off drag. Although the 46 wasn't the straight line dragster of the 45, it wasn't a slouch on the straights.
Wouldn't be surprised if they'd like to get back that dragster characteristic. When you're kind of mid-back pack, points are hard to get and if you can excel at just a handful of tracks thanks to some particularly strong characteristic, it can net some larger than average haul of points. Beats simply being semi-lackluster everywhere.

That's a lovely blue. Would love to see this car fighting stronger in the mid-field.

There is a undercut of the undercut on FW47

It almost looks like an inverted version of the bathtub designs...

Or is that shadows/reflections playing a trick?

No paint above the exhaust becouse of the temperature probably, and a good look at the small T wing on the rear wing pillar.

Underneath part of the sidepod with tunnel alike shape looks very intersting.
I do not know if they already have that.
