The McLaren and Aston Martin Formula 1 teams are preparing for a “Super Sunday” in Brazil. For just the sixth time in the sport’s history, both qualifying and the race are taking place on the same day. Stormy weather is testing the teams’ resources and resolve at the Interlagos Circuit, home to the Sao Paulo Grand Prix. The teams and drivers arrive at the track at the crack of dawn, ready to think on their feet in a marathon day ahead.

After a well-orchestrated performance in Saturday’s Sprint Race, Championship contenders McLaren are looking to seize advantage on Sunday. Lando Norris and Oscar Piastri know they must work together to claim maximum points for the team. At Aston Martin, Fernando Alonso and Lance Stroll sense an opportunity in the wet. All the drivers know that rain can level the playing field at any grand prix, and this weekend is no different.

It’s the Monday after the race before. Brazil’s historic Interlagos circuit staged another epic grand prix, and one which may prove pivotal in McLaren’s hunt for both World titles. Now, it’s time for the Aston Martin and McLaren teams to return to their factories. Back at base, they can analyse their performance with the bulk of the team who don’t travel to the races.

Aston Martin race engineers Chris Cronin and Andrew Vizard explain how vital the factory debriefs are to understanding what went right - or wrong - after every race, and how to take the learnings into the next event. Drivers Stroll and Alonso may be taking time to recuperate after an epic race weekend but they stay in touch with their engineers and work going on back at base.

At McLaren, team boss Andrea Stella is making it his mission to create a winning culture at the factory, as well as at the track. The Italian is only in his second season as team principal but has driven the team into title contention. Back at base, he shares some of the secrets to his success so far.

Aston Martin are also plotting a renaissance under new Group CEO Andy Cowell. Our guides Sarah Holt and Holly Samos are given a VIP pass to join the workforce assembled at the heart of the factory as Cowell makes his first address to the team.

While Aston Martin are looking to the future, McLaren must focus on the present. This is a team who has won multiple World titles. Now the factory is fixed on ending the 26-year wait for the next Constructors’ crown and they are determined to protect their lead over rivals Ferrari and Red Bull. British star Lando Norris hasn’t given up his hopes of reeling in reigning champion Max Verstappen in the drivers’ standings. With three races left to go in the 2024 season, there is still all to play for.
