2023 car comparison thread

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.

Hopefully this isn't repeating content that is already here too much.

Are there pictures or video like this at turn 13 to see how low the cars are and if they are porpoising?

This was brilliant demonstration of what causes porpoising, how the floor works and how the seal the floors.

Really? Because he didn't even produce visible oscillations, which I expected...

Can somebody explain to me why the regs wouldn’t permit a manufacturer from minimizing the floors downforce (using the floor more like a barge board) and instead creates more of the downforce overbody such that the car acts like the faster 2021 version?

AMR22 vs AMR23 vs RB18 vs RB19 brake caliper.

It seems that both RB and AMR brought this "pins and needles" brake caliper design for 2023. It didn't feature on either team's cars in 2022. What an interesting coincidence.

The AMR22 has fins/ribs on its caliper if you looks closely. So the engineers did have the concept of extended surfaces in mind but used studs instead in 2023. Possibly because of design changes with the caliper and resulting differences with airflow and maybe even for weight purposes.

In fact the amr23 is a mix of fins and studs.
For Sure!!

In short, because the rules are very restrictive on the use of "overbody"-aerodynamic devices. It would be impossible to generate the overbody downforce that would be necessary to even begin to approach the downforce of the underbody. However, it is important to note that F1 cars have been generating most of their downforce through the underbody for many years. Already in 2004 it was 45%. In 2009 it was around 50%, and the percentage has been rising steadily. Underbody downforce produces less drag than overbody downforce, so it is always more effective to seek more downforce from the underbody.

In mid 2000s underbody rules were much less restrictive, higher diffusers and so on. Then they continuously got more and more nerfed. 2014-2016 floors were very simplistic and shallow.

That's right, but the designers always found ways to improve underfloor performance and even in these years 45% of the downforce was produced by the underfloor. It was always the component that provided the most downforce for the minimum drag, just as it provided over 50% of the total downforce from 2017 and far more today.

Great comparison of the Red Bull and the AM that shows these cars really have a lot of similarities. Wheelsbase, Driver Position, sidepod positioning etc. all seems to be practically idendtical or pretty close:

I'm not sure why your pictures are always posted in smallest resolution, but this one would be much better in full size :)

Is this from Jeddah? It's interesting how much more cooling openings the Aston has. The bathtub probably means they can't quite get the cooling exhaust out to the back of the car efficiently.
