Ferrari Leads F1 Upgrade Battle with Double-Digit Changes in Miami

Ferrari has brought a staggering eleven updates to its SF-26 car for the Miami Grand Prix, leading a wave of technical developments as almost every Formula 1 team returns from the spring break with new parts. Only Aston Martin has not declared any upgrades for this weekend, while rivals like McLaren and Red Bull have introduced seven significant changes each in a bid to close performance gaps and adapt to the challenging Miami conditions.

Why it matters:

The Miami Grand Prix serves as a critical mid-season development checkpoint, offering the first major opportunity for teams to implement learnings from the opening races. The sheer volume of upgrades, especially from Ferrari, signals an intense arms race to improve car performance ahead of the European season. For teams like Mercedes and Red Bull, these updates are key to maintaining or reclaiming competitive advantage, while for the midfield, they represent a chance to make decisive gains in the constructors' championship.

The details:

• Ferrari (11 updates): The Scuderia's major package is headlined by a reprofiled front floor and floor edge, plus extensive revisions to the rear of the car including a new diffuser, rear suspension, beam wing, and rear wing assembly. Changes also extend to the front wing endplate and front corner.
• McLaren (7 updates): The constructors' champions have unveiled what is effectively a new MCL40, with comprehensive bodywork revisions. The updates include a revised front corner, new engine cover and sidepods, a new floor body, rear corner, and rear wing—all aimed at increasing load and improving airflow. The team has also added circuit-specific cooling louvres for Miami's heat.
• Red Bull (7 updates): The RB22 features considerable sidepod changes among its seven upgrades, which also include a new front wing, front corner, engine cover, floor, and rear corner. The team is also testing a new rear wing concept and has reportedly shaved approximately 6kg off the car's weight.
• Mercedes (2 updates): The championship leaders have taken a more measured approach, introducing only two new parts: repositioned tailpipes to reduce drag and improve downforce response, and a new front corner. More substantial updates are expected for the next round in Canada.
• Other Teams:
  • Williams has seven new parts on the FW48, including various bodywork elements.
  • Racing Bulls has six enhancements to the VCARB 03.
  • Alpine has updated the front corner, rear suspension, and will test a new rear wing. Franco Colapinto will also run a new chassis.
  • Audi has a reworked front suspension, floor edge, and diffuser.
  • Cadillac has brought nine upgrades focused on performance and ride height sensitivity.
  • Haas has only amended the diffuser on the VF-26.
  • Aston Martin is the sole team without any declared upgrades for the AMR26.

What's next:

The true test of these upgrades will come during Friday's extended practice session and throughout the Miami Grand Prix weekend. Teams will be gathering critical data on how the new parts perform in the unique heat and humidity, with an eye on optimizing setups for qualifying and the race. The results here will validate development directions and set the tone for the upcoming European leg of the championship, where the development race is expected to intensify further.
