Aston Martin and Alpine have both made significant updates to their Formula 1 cars ahead of the Monaco Grand Prix. Aston Martin has introduced a range of changes to the rear of the car, including optimised flow on the engine cover, floor body and floor edge. The team has also introduced a new cooling panel to improve cooling performance and modified the rear suspension fairings to work in conjunction with a new rear brake duct fence. Further updates not used in Monaco will be rolled over to the Spanish GP.
Meanwhile, Alpine has made extensive changes to its sidepod architecture, which now incorporates a wider and taller water slide-style gulley. This should improve flow down the car’s flank and over the floor, both of which have also been modified. The team has also angled the upper transitional tip section of the rear wing endplate on top of the mainplane section, and added guide vanes to the inner drum on the rear brake assembly to alter the airflow.
As for Mercedes, Valtteri Bottas placed eighth in FP2 at Monaco, suggesting that the team’s extensive revisions, including high downforce circuit-specific updates, could have shifted it up a gear in the ultra-tight midfield battle. The team’s changes are mainly at the rear, with the engine cover, floor body and floor edge optimised for better flow conditions and cooling performance. The rear suspension fairings have also been modified to work with a new rear brake duct fence and a new, high downforce rear and beam wing variant has been introduced for Monaco.
The cancellation of the Emilia Romagna Grand Prix has led to the rolling over of a lot of upgrades planned for that round to Monaco. Aston Martin opted to introduce the ones most suited to the demands of Monaco, while the rest will be carried over to the Spanish GP. The team’s upper wishbone fairing has been modified and now features a twisted profile across its span to improve flow downstream. The lower front brake duct deflector has also been repositioned and the suspension fairings have been fettled to alter their incidence.
Alpine has also almost simultaneously arrived at Aston Martin‘s water slide-style gulley, taking it to a more extreme level than before. This should help with flow down the car’s flank and over the floor, both of which have been modified. The upper transitional tip section of the rear wing endplate has also been angled on top of the mainplane section, rather than sitting parallel with it.
