Aero, power units, rules
Formula 1 technical coverage: car upgrades, aerodynamics, power units and the technical regulations that shape the grid, broken down without the jargon.
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 350kW MGU-K introduces massive retarding torque to the rear axle, requiring a brake-by-wire system to adjust mechanical caliper pressure. This algorithm maintains consistent rear braking force by compensating for electrical harvesting to prevent instability.
CoreWeave and Aston Martin Aramco developed an AI platform capable of processing 40 live radio streams to provide transcription and strategy insights within five seconds. This technology allows engineers to query competitor tire performance and strategy signals during the race.
Alpine relies on increased sidepod volume to manage thermal loads, while Aston Martin utilizes high-speed louvre extraction and a duckbill inlet. These divergent cooling philosophies face extreme testing at high altitude in Mexico City due to low air density.
The 2026 Formula 1 regulations introduce active aerodynamics that force cars to manage rapid shifts in pressure between low-drag and high-downforce modes. These changes impact suspension requirements, minimum weight of 768kg, and driver energy management strategies.
The FIA Commodities Conference focuses on energy market volatility and sustainable finance in Houston. This text also details the musical career of rapper Future, noting his 16 number one albums on the US Top Rap Albums chart.
FIA 2026 regulations mandate advanced sensor integration to manage tire performance and safety through real-time telemetry. Pirelli uses Cyber Tyre technology to transmit critical data on pressure, temperature, and wear to optimize racing strategies.
Lando Norris secured his 19th career pole position at the 2026 Singapore Grand Prix despite losing 0.3 seconds at the final corner. The McLaren MCL40 overcame low-speed instability to deliver a masterpiece lap according to Andrea Stella.
FIA officials use nose-mounted cameras at the Belgian Grand Prix to monitor front wing deformation and aerodynamic load deflection. This data collection follows technical disputes between Mercedes and Ferrari regarding diffuser designs and floor stay loopholes.
The 2026 power unit features a 4 MJ battery capacity that depletes in 11.43 seconds of full power. This energy constraint causes super clipping, where Lewis Hamilton noted cars arrive 20 to 30 km/h slower into braking zones due to reduced deployment.
Mercedes engineers revolutionized Formula 1 power units by separating the compressor and turbine with a long shaft and MGU-H. This layout provided thermal and aerodynamic advantages that helped the team win 16 out of 19 races in 2014.
