While Red Bull did issue some launch renders these are never particularly reliable sources, so I’m not going to use those much here. 
Aston Martin claim that the team hope to be fully in the development fight this season, last year the team’s development stalled out badly and the AMR23 became less competitive.
The VCARB01 was developed in the Red Bull wind tunnel, at the old RAE Bedford facility in England, it utilised the oldest wind tunnel in the UK - more on that here -
At first glance the car seems to have a lot in common with the late season A523, but according to the team the new car is a “brand-new concept created for the next two seasons.” This may suggest that the chassis may carry over into next season. 
I put that question to @paddylowe when he was in charge at Williams - this is what he told me: "I don’t actually remember the history of how all the other teams migrated to having the dash on the steering wheel, or indeed why they did it".... 
Starting at the front Ferrari has changed its nose concept, with the blunter tip no longer meeting the forward most wing element as was the case with the F1-75 (shown for comparison). Instead it joins the second element, while the leading edge has a noticeable dip in the centre. 
Renault owned Alpine launched the new A522 Formula 1 car in a ceremony in Paris, however the cars at the launch were simply show cars. The real A522 would appear shortly afterwards in Catalunya. 
The long wheelbase, and indeed the whole concept of the W11/W12 has been replaced as a result of the new rules this year, so don’t expect much carry over. Compared to last year the team has stated that only the steering wheel remains the same. 
Great hopes have been placed on the F1-75 as Ferrari diverted most of its technical effort in 2020 and 2021 to this design, so it should, in theory at least be a step forward from last season. The team calls it an innovative and daring design. 
Why did Williams do the showcar -real car shuffle? almost certainly as its online launch video and media assets had been created earlier. It probably wasn’t directly to hide anything… probably. Though the team has only released two images of the real FW44. ( showcar render here) 
Most strikingly the McLaren is very different to the Aston Martin AMR22 (the only other 2022 F1 car to be launched at the time of writing. Unfortunately McLaren would not let us take any pictures of the real car, meaning that at present only renders are available. 
The car features a Mercedes power unit and Mercedes transmission, but unlike the AMR21 and R20 this car is not based on a Mercedes car concept. Surprisingly Aston Marin claims that 10% of the car has carried over from the AMR21. 
Aston Martin were trying an alternate strategy with Lance Stroll during the race, starting on the (C3) hard tyre and running deep into the race, hoping for a safety car and to get track position as a result. It seemed to be going well, and then it wasn't. 
When Bottas pitted the wheel gun stripped the wheel nut, rounding it off, and leaving no faces for the tool to drive on. This was one of those moments where F1 TV's Pit Lane Channel came into its own. 2/8 
On Friday - after Free Practice the rules relating to track limits at T4 were changed. "Advantage" in terms of 27.3 here means overtaking or defending not lap time. This document was circulated to teams and drivers. /2
