Formula 1 teams couldn't do without them and drivers spend hours using them. Simulators are a vital tool for every team in F1, but why? Katie and Christian talk to four sim experts to explain all.

Stoffel Vandoorne, Aston Martin's reserve driver, took a break from a long day in the sim to tell us why they're so useful for racers. Alpine's Technical Director Matt Harman breaks down how teams use them to test new parts and car set-ups. Motorsport scientist Dr Diandra Leslie-Pelecky explains how simulators work and why they're so realistic. Plus a chat with Red Bull Racing Esports star Sebastian Job, who went from winning on video games to working in the real Red Bull F1 simulator, working on race weekend set-ups for Sergio Perez and Max Verstappen.
