While it is clear to see that the C43 harbours some affect from its predecessor, there’s additionally a plethora of recent options to debate too.
These usually are not solely vital when it comes to this automotive but additionally set the desk when it comes to the route we would see others take heading into 2023 too.
The headline options we have to give attention to are the sidepods and flooring edge.
The sidepods particularly appear to take inspiration from each Pink Bull and Ferrari, with the inlet measurement and form similar to what we noticed from the Scuderia in 2022.

Given its use of the Ferrari energy unit, this won’t appear uncommon however, relatively than acceptable the complete bathtub model sidepod answer seen on the F1-75, Alfa Romeo has as an alternative sought inspiration from Pink Bull,
This not solely comes within the type of the downwash ramp answer but additionally the shelf strategy taken with the engine cowl.
It is a resolution that not solely revolves round aerodynamic features although, with a trade-off made to accommodate a extra environment friendly centreline cooling answer that the staff could not change to in the course of the course of final season.
The staff has additionally paired these adjustments with alterations to its rear suspension and gearbox, which is not going to solely bear fruit from a mechanical standpoint but additionally work in concord with the opposite aerodynamic design adjustments, particularly noting the big undercut and tapering accomplished to encourage the airflows passage into the coke bottle area.
You will additionally word that to complement the smaller rear cooling outlet on the rear of the automotive, the staff has put in cooling gills on each the higher floor of the sidepod and on the shelf part of the engine cowl.
It is probably we’re seeing the automotive in additional of a most cooling configuration in these photographs, as different groups that took this route final season usually did not have these gills open always, utilizing interchangeable bodywork panels as a way to make these adjustments.

The beam wing has additionally been handled to a brand new geometry, as we discover a wavy trailing fringe of the higher flap, just like the tubercle-like answer we noticed McLaren use on its rear wing in 2014.
The ground’s edge can also be a departure from what we noticed final season, which is primarily a response to the change in regulation requiring a 15mm uplift.
Clearly, groups see these regulation adjustments as a possibility, relatively than bemoaning any benefits they might have misplaced as a consequence.
In Alfa Romeo’s case, it has opted to run the ahead and rear sections of the ground on the decrease peak that is nonetheless permitted, however within the center, we discover that the ground has been reduce up into a number of flaps. These ought to work the airflow tougher and assist to bridge the efficiency hole that is opened up by the regulatory adjustments.
Nonetheless, as we have seen prior to now, while this looks as if an attention-grabbing strategy, this portion of the automotive is more likely to evolve fairly quickly and it may even be an early model of what the staff labored on.
The bigger rear view mirrors which are required by the laws have additionally manifested in a a lot wider meeting on the C43, with their physique clearly tapered equally to the sidepod beneath.

Following the accident involving Guanyu Zhou at Silverstone final yr, adjustments have been made to the laws relating to the design of the roll hoops for 2023, with much more stringent laws following for 2024.
As a consequence, some may need anticipated that the C43 would revert to a extra typical design. Nonetheless, as explained by Jan Monchaux, it was just a little late within the design cycle for that and the blade design may very well be optimised to swimsuit.
In the meantime, the obvious distinction between this and final yr’s automotive is the livery, with the staff having taken benefit of the shift from white and pink to black and pink as a way to avoid wasting weight.
This was an strategy taken by a lot of its rivals final season, as they stripped away segments of their livery to reveal the naked carbon of the bodywork. This helped them to decrease their automotive’s total weight and try and get nearer to the minimal specified within the laws.
The method probably solely saved a handful of grammes however all the pieces counts when it comes to lap time. And, with a ground-up strategy to this when it comes to designing the livery, there’s undoubtedly extra that may be saved.
