F1: Chequered Flag

Inside the Williams and Mercedes factories, where F1 cars come to life, the workforce is putting its heart and soul into the winter tasks now well underway. There are just 14 weeks between the 2023 season and the first race of 2024 in Bahrain. In this series, we have been allowed rare access into the heart of the operations. And at the Williams facility, in rural Oxfordshire, we are about to go on a VIP tour to learn how to build an F1 car.At Brackley, home to the Mercedes’ F1 team, the factory is united by a common purpose. Mercedes dominated F1 from 2014. But when new technical rules came in at the start of 2022, Red Bull overtook Mercedes as the fastest team on track. The desire to return Mercedes to the top runs deep - and for a very significant reason. The motivation to get the 2024 car right is massive for both teams - but first Williams and Mercedes have to absorb the lessons from last season’s car. And each team has a very specific problem that it now wants to put right. At Brackley, work continues around the clock on the new Mercedes and the Williams factory is also working at full capacity - with extra shifts and overtime standard at this crucial time in the car build. The factories are moving up a gear, because a new car for a new season - that’s a chance to start again.F1: Back at Base is an IMG Production for the BBC Narrated by Joseph Fiennes Co-hosts & Executive Producers are Holly Samos and Sarah Holt The Producers are Alasdair Cresswell, Joe Aldridge and Jack Winstanley.

The Williams and Mercedes Formula 1 teams have given us unprecedented access to their top-secret facilities as they work over the winter preparing their cars for the 2024 season. At Mercedes, the team’s superstar driver Lewis Hamilton is going into a restricted area to see how that crucial work is coming along. We follow in his footsteps as F1 experts Holly Samos and Sarah Holt get a VIP tour of one of the most important tools when it comes to designing and building the most complex race cars in the world. From his position at the very top, Mercedes team principal and CEO Toto Wolff is reflecting on how the team lost ground when major new technical regulations on car design came in for the 2022 season. At Williams, new team principal James Vowles is welcoming his first major hire - as they plot a return to the front of the grid for the nine-time World Champions. The duo are part of a crack team back at base who have been getting to grips with the 2024 car since last March.At both teams, the drivers also have their wish-list for the new cars. Alex Albon knows what avenue he wants Williams to go down and there is one person Hamilton has on speed dial when it comes to car design. The cars that will be driven by Albon, Hamilton & co during the 2024 season are being built by 1000s of people. It’s time for them to get to work - as the race to the 2024 season picks up pace.F1: Back at Base is an IMG Production for the BBC Narrated by Joseph Fiennes Co-hosts & Executive Producers are Holly Samos and Sarah Holt The Producers are Alasdair Cresswell, Joe Aldridge and Jack Winstanley.
