RacingNews365 technical expert Paolo Filisetti analyses the leading F1 teams’ areas of focus ahead of the Miami Grand Prix — with an emphasis on the issues plaguing Red Bull.
All 11 F1 teams are using April to finalize upgrade packages set to debut at the Miami Grand Prix, most of which were already planned within structured development roadmaps. However, early-season performance across the opening three races has inevitably prompted some revisions to initial targets. Mercedes, despite currently fielding the car to beat, will introduce updates in line with its original program. The team has encountered only minor reliability concerns so far — primarily software-related issues that surfaced intermittently during the first three race weekends. A key objective for the W17’s ongoing development is a gradual weight reduction, aimed at increasing ballast flexibility and optimizing weight distribution. Aerodynamic refinements are also expected, with early indications pointing to a further evolution of the car’s concept, particularly at the rear end. By contrast, Ferrari is set to revise the aerodynamic concept of the SF-26 around its so-called ‘macarena’ rear wing philosophy — a solution centered on maximizing airflow efficiency. The updates will focus primarily on the floor and the lower section of the sidepods, alongside revised front wing flap geometries. In addition, a significant step forward is expected in the software governing energy recovery systems. Elsewhere, McLaren will introduce a substantial upgrade package in Miami, designed to move the MCL40 beyond the ‘under development’ phase that has defined its season so far.
