Lewis Hamilton is providing technical feedback to Ferrari engineers to optimize the 2027 chassis and aerodynamic package. While working on future performance, Hamilton finished fourth at the United States Grand Prix after struggling with understeer issues.
The FIA is intervening in a technical dispute by mandating uniform rim cover shapes to stop teams like Red Bull and Mercedes from manipulating airflow. This standardization aims to reduce tire-induced turbulence and improve racing quality by stabilizing airflow for following cars.
Red Bull technical director Pierre Waché reveals that the 2027 RB23 will feature a new chassis and gearbox to address current car limitations. The team aims to maximize performance through new aerodynamic and mechanical parts while managing the budget cap constraints.
Ferrari brings its fourth significant aerodynamic package of the 2026 season to the United States Grand Prix, focusing on floor and sidepod revisions. Engineers aim to increase downforce and widen the operating window of the SF-26 to address performance issues identified at Zandvoort.
Mercedes deputy technical director Simone Resta revealed the team rejected the Macarena wing concept due to a downforce compromise. Meanwhile, Kimi Antonelli leads the championship with a 102 point advantage over George Russell heading into the United States Grand Prix.
Andrea Stella admits McLaren cannot fix car handling characteristics without fundamental changes arriving in 2027. Lando Norris and Oscar Piastri struggle with a car described as being on a knife edge, requiring intense mental concentration to maintain competitiveness.
McLaren transitioned to a push-rod front suspension for the MCL40 to accommodate 2026 aerodynamic regulations. Chief designer Rob Marshall notes the new front wing real estate allows wishbones to manage airflow more effectively than the previous pull-rod setup.
Loïc Serra leads the technical supervision for Ferrari's 2026 SF-26 project as the team prepares for major regulatory changes. Development focuses on power unit energy recovery, chassis balance, and tire management to maintain competitiveness against rivals.
Ferrari utilizes pushrod actuation on the SF-26 to improve aerodynamic stability and airflow. This mechanical shift impacts ride height management, which proved critical when Charles Leclerc faced disqualification at the United States Grand Prix due to excessive plank wear.
Mercedes faces a 60-hour wind tunnel limit and tight cash constraints as they attempt to rebuild their development pipeline. Toto Wolff noted the squad is low on cash after spending $1.8 million on crash damage, impacting the budget for upcoming performance upgrades.
The Williams FW48 struggles with a heavy 772.4 kg chassis in high-downforce sectors, while the Adrian Newey-designed Aston Martin AMR26 utilizes active aerodynamics to excel on the long Turn 12 straight. This technical divergence will dictate overtaking opportunities at the Austin circuit.
FIA regulations for 2026 aim to achieve 90% downforce retention behind lead cars by managing tyre wake through new wheel covers and inwash sidepod boards. These technical changes target the dirty air problems that caused performance decay in previous racing cycles.
