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.

So no new gearbox at the end. They're keeping the pull rod suspension.

Looks like an understandable evolution of the FW46. I imagine this will be the case up and down the field.

Let us hope it has some easy to release performance straight out of the gate otherwise it will be a long old season.
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.

Do we know if Williams have taken Mercs updated rear suspension, or are they sticking with the Merc 23 rear like last year (I assume if so due to be familiar with it and prioritising other development areas)? I can't tell from the images.

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

There is a undercut of the undercut on FW47

I always get an impression of an unrefined structure/not finished car if I am looking at these flat surfaces, straight lines especially at the sidepod. Is anyone else doing such straight lines?

Rear suspension is pushrod. No confirmation of it being the 2024 or 2025 Mercedes design.

The whole floor is really weird. The SIS is placed in such a way that it really pokes out of the floor a lot. It's almost like a secondary small outwashing element. I wonder what kind of purpose such a solution might serve. Is it just to have a really clean, massive underfloor or could it serve some other purpose?

Would the pseudo-bargeboard SIS bump be attempting to push air out before it starts interfering with the airflow around the floor edge wing?

I'd say this floor design really looks quite aggressive from Williams. It looks like nothing I've ever seen from this generation of cars.

The general trend in 2024 was towards lower complexity. Ferrari abandoned their super complex floor design for a much more "basic" one. Weird solutions like S-ducts and bathtub sidepods disappeared entirely. Red Bull went back on all of their weird intakes and really unconventional cannon design. "Waterslide" sidepods gradually became less extreme over the season, especailly compared to 2023. Mercedes fully abandoned their zeropod concept. Mercedes also abandoned their "pseudo-Y250" wing and Alpine stopped bringing their really exotic front wings like this one.

It really does appear that the trend has been towards more simplistic design language, especially when it comes to intakes and floor geometry, but to some extent also with overbody aero. Admittedly small aero devices like winglets and wing mirrors keep getting more complex, but wings and sidepods are definitely getting smoother and less aggressive.

My interpretation of this is that the complexity of solutions gave really good downforce readings in the wind tunnel, but caused a lot of really bad correlation issues. So the teams simply abandoned a lot of the complex geometries to optimize around simpler, more predictable solutions that gave more reliable readings because it's better to have a car you trust than one that is "better", but completely impossible to tame.

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.

With how high the venturi intake is, I don't know if it really matters much with the SIS being that bulgy. It might be more for the underfloor design or interior packaging. The venturi intake is looks quite agressive from these pictures.
