Williams Racing is making substantial updates to their car ahead of the Miami Grand Prix, with a complete overhaul of the bodywork aimed at enhancing performance. The team is introducing a new floor, side pods, engine cover, and a modified rear suspension geometry, all designed to reduce weight and improve handling. Team principal James Vowles emphasized the effort to provide drivers Carlos Sainz and Alexander Albon with a 'worthy car.' In contrast, Aston Martin's AMR26, driven by Fernando Alonso, will not see any new external components, as the team prioritizes collaboration with Honda to address vibration issues and improve car handling. Other teams like Ferrari and McLaren are also rolling out significant upgrades, with Ferrari focusing on the floor, diffuser, and rear suspension. The effectiveness of these changes will be closely watched in the upcoming races.
