F1 Explains is back for 2024! Christian Hewgill and Katie Osborne are starting by answering your questions about new F1 cars. When do teams start working on their challengers for a new season? How much of a new F1 car is actually new? What happens when a team comes up with something that has never been seen before?

Aston Martin's Technical Director Dan Fallows explains how a new Formula 1 car goes from sketches on paper to carbon-fibre reality.
