In the world of Formula 1, constant updates are necessary for teams to keep up with their rivals. Since 2009 there has been a ban on most mid-season testing, meaning that high-tech simulators are now the best way for engineers to gauge the effectiveness of updates before a race weekend, as well as preparing the drivers.

Ahead of this weekend’s Hungarian Grand Prix, Williams opened up their doors to CNN for an exclusive look at their simulator facility. Reserve driver Valtteri Bottas and Senior Operations Engineer Dominic Harlow talk about their work in between races.
