The @AstonMartinF1 #AMR22 is the first 2022 #F1 car to be revealed, and as such gives us a first real indication of the trends expected this season. Tech thread..

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.

Starting at the front the most striking feature of the car is the tip of the nose, set back from the leading edge of the front wing and slightly above it. It is a design hinted at in some of @F1’s 2022 renders. It will be interesting to see if other teams follow this lead.

Note how the second highest wing element blends into the nose. The nose is not a simple thing to change as it requires a crash test - so will be interesting if other teams follow this lead. The small hole is for driver cooling.

The front wing is of interest, noticeably different in shape to the more curved wings fitted to the show cars. Note how angular the upper element is, also note how the outer edges of the wing drop down.

The front wing endplate is fairly standard within the rules, but the single external element or dive plane is an area open for team development, it will be interesting to see if this becomes anymore complex as the season gets under way.

Looking at the inner face of the end plate it is possible to see how much wider the lower elements are at the outer end of the wing are compared to the two upper elements. On the show car these were far more evenly spaced, and not as blended with the nose.

Aston Martin has opted to retain pushrod actuated front suspension, some teams are expected to utilise pull-rod. The reasons for this are detailed here:

The front brake duct is an area where some development is expected, the small duct on the tyre side of the rim plate is interesting. Note the front wheel flow conditioner (needs a better name), standard to all cars.

There is a lot of interest in the radiator duct inlet, smaller and far squarer than expected, also note the internal sweep channelling the airflow outward under the bodywork. Notably Haas has a similar concept on display on its otherwise vague renders.

The shape of the sidepod further rearward is interesting, as it sticks out above the floor a long way - a bit like a Toro Rosso STR6. Have a look here for a theory on the cooler layout under the bodywork in this area:

On top of the sidepod are a number of cooling slats (or gills as @AlexBrundle calls them) this is likely to be an area with a lot of development track to track.

The roll hoop concept is a straight carry over from the AMR21, and is an indication that most Mercedes powered cars will have a similar layout.

That roll hoop concept can be traced right back to the Mercedes W10!

At the rear of the car things are a little less clear, we can see that the AMR22 uses a pull rod rear suspension layout, and that the rear floor is pretty close to that of the show cars (as expected)

There is a distinctive hump on the engine cover, something required to accommodate the plenums of the Mercedes V6, they also appeared on the AMR21 but seem to be slightly longer and thinner on the AMR22 - expect these on the W13 as well.

DRS! The first proper look at a 2022 DRS design, and its pretty much as expected. Question is, how powerful will it be?

The only real look at the rear of the car is in the form of renders, which do not really give much of a clue about the design. So that will be something to look at after the shakedown.

So thats pretty much it for my first impressions, will have a lot more when we see it on track.
