The Swiss outfit become the fourth team to show off their new-look livery for the upcoming campaign with drivers Valtteri Bottas and Zhou Guanyu taking the covers off a showcar. Alfa Romeo also released CGI images of the C43, which provided the clearest indication yet of how their actual 2023 car will look.

The rear suspension, bodywork, gearbox and cooling elements have been reworked, while revisions have also been made to the floor amid a rule change designed to combat porpoising. “Just seeing the evolution of the regs last year we had to acknowledge that there were better solutions on how to manage the flow to the diffuser, between the rear tyres,” Monchaux explained. “But because of the decision we had made from an architectural point of view, we were stuck in a corner.“So, it’s not a revolution, it’s a similar solution already on the grid last year, but it’s something we couldn’t implement without a major change of the architecture.“From what we’ve seen, some of the weaknesses we had from an aero point of view which was effectively high-speed performance has been also significantly improving thanks also to the new potential we unleashed with this new bodywork and this new way of working the floor between the rear tyres.”What about the front?Monchaux revealed that Alfa Romeo ultimately decided to favour development at the rear-end of the car as part of a strategic call influenced by aerodynamic testing and budgetary constraints. Although he believes the biggest performance gains can be found at the rear, Monchaux insisted Alfa Romeo have still been working on improvements at the front of the car. “The front-end is more difficult in terms of development in the numerical world and in the wind tunnel,” he said. “Let’s say the return in investment is smaller. That doesn’t mean there is no performance. As long as we are not first in the timing sheets we have performance to grab everywhere, but since you’ve got a limited amount of wind tunnel runs, and also limited resources, at some point you need to make strategic calls. “Where am I investing the majority of my resources? And I am more in favour of doing one thing properly than starting five different dishes and then end up with solutions that are just marginally better. “The front end we have been working on and there will also be significant changes presented at the start of the season. “4“But generally speaking, for us, it an area we have struggled to put more performance because of the constraints of the regulations than the floor, which is offering much more freedom.”
