The prize for winning our World's Fastest Gamer esports competition is a role as McLaren's sim driver - a role that is imperative to the team's testing and development. 

Each season, F1 teams are only allocated a limited number of test days, meaning car development would be extremely difficult without the help of a simulator and its driver.

McLaren engineers Tom Stallard, Will Joseph and Andrew Jarvis explain why the winner of WFG will have a big job to do.
