From Lewis Hamilton revealing where Ferrari must improve in 2027 to Bridgestone and Michelin considering returns to Formula 1, here are the main Formula 1 stories of the day.

Ferrari finished second and fourth at the United States Grand Prix, with Charles Leclerc ahead of Lewis Hamilton. Hamilton believes the team still has work to do before it can regularly fight for victories.

The seven-time world champion is already focused on next season. He says he has been involved in discussions about how Ferrari can improve its 2027 car and close the gap to its rivals.

Hamilton’s feedback is being passed to the engineers developing next year’s car, particularly on the chassis and aerodynamics. He says those conversations are continuing over the coming races.

"I feel like the team have been doing a really, really good job. I acknowledge it. I think also, in the background, I'm working on this pivotal moment in terms of steering the car in the right direction for next year," Hamilton explained.

"I'm really working on areas that we need to improve for next year's car. That's part of the discussion this weekend and the next couple of weekends. The feedback to the guys who are designing the parts for next year is just pointing out to them where we can improve on the actual chassis side and aero package."

Pirelli’s current contract as Formula 1’s exclusive tyre supplier runs until the end of 2028. The Italian manufacturer could continue, but it will have to compete for a new deal through an upcoming FIA tender.

Bridgestone is once again being linked with a return to the sport, while Michelin is also monitoring the situation. A senior Michelin delegation attended the Italian Grand Prix to explore the possibility of becoming F1’s tyre supplier.

Pirelli could have an advantage if it enters the tender. The manufacturer has years of experience working with the teams and the sport, which was previously a key reason for extending its agreement.

The timing could make it harder for a new supplier to match Pirelli. A successful bidder would need to provide tyres from 2029, while the design of the current generation of cars is expected to change little before the end of 2030. Pirelli’s experience with these cars from 2026 to 2028 could be difficult for a rival to replicate quickly.

A new supplier might therefore find it easier to enter when the next generation of cars arrives, currently planned for 2031. Even so, interest from multiple manufacturers is a positive sign for F1, whose growing popularity has helped attract potential suppliers.
