Quick armchair analysis of the SF-23:
Front end
Front end is surprisingly different to last year. Whereas most of the grid has copied the f1-75's nose and front wing, ferrari have gone aggressive with the front wing with vortex generating struts (which may or may not be legal) and a much thinner nose than the competition which starts on the 2nd front wing element instead of 1st.
Front suspension is still pushrod but with the track rod integrated into lower wishbone (like all the aldo Costa cars since 2004 / their 1st time using this solution in over a decade).
Middle part
Possibly the most interesting part of the actual 2023 cars launched so far. They've evolved the bathtub but it tapers much earlier into the coke bottle / has the slimmest rear end so far. The front/mid section of the sidepods region is where there is a lot of interest. The lower SIS is raised to the point it isnt obstructing the bargeboard/ front tunnel region. The inlet is the same but it appears ferrari have somehow introduced 2 s ducts in the sidepods which exit behind the halo. The exit also appears to have some winglets which are surprisingly allowed in this region due to minimal turbulence. Ferrari haven't gone for a cannon outlet but have introduced more gills into the upper side pod.
Rear end
Ferrari have done something I'm surprised not many teams outside of rb have done and that is using a multilink rear suspension, however surprisingly like merc, they've gone for pullrod instead of pushrods.
The the diffuser sidewalks also appear to have a double hole in them to the extent it looks like a turning vane.
Overall, id say this car looks visually better than the f1-75 and should be interesting to see how it compares to the competition
