The more restrictive practice times presented by a sprint race weekend, allied to the tricky circumstances at Losail, have noticeably deterred various teams from spending time trying out new developments. The sprint race weekend only offers a single practice session before cars are confined to parc ferme conditions. With these constraints in mind, seven teams have made no enhancements to their 2023 challengers, and the three that brought modifications are minor.
Alpine team, in its approach to adapt, made three specific upgrades to the A523 model. One among these upgrades is a raised diffuser sidewall cut-out in the tyre flank region, which is slated to bring a downforce gain, prominently at low rear ride height setups. Apart from this, they are also testing a revised orientation of the rear brake drum lower flick geometry with the aim of reducing drag.
The team has proposed revisions to the cooling vents on the engine cover that are being tried out, keeping in mind the extreme requirements that are expected at the forthcoming Mexican Grand Prix. These adaptations follow a substantial upgrade package that the Enstone-based team introduced at the Singapore Grand Prix last month.
The Alfa Romeo team has integrated updated beam wing elements and made alterations to the bottom part of the rear wing endplate. In its pre-event submission, the Swiss team stated clearly, “The upgrade to the beam wing and end plates is part of the upgrade package introduced over the last couple of events and is designed to work in conjunction with it, enhancing the aero flow throughout the bodywork of the car.”
AlphaTauri, on the other hand, has centred its tweaks around the floor design of the car. The front section of the floor edge has experienced modification. These adaptations aid in reducing the pressure on the edge of the floor, and pull a larger flow through the fences, which is predicted to boost the downforce. These improvements come in the wake of a significant upgrade that AlphaTauri brought to its car in Singapore, aiming at a downforce gain and amelioration of some car traits that its drivers had wrestled with previously.
