Just what all goes in to design and erect an FIA/FIM-homologated motor-racing circuit that is used for Formula 1, MotoGP, Formula E & other series? What are the design, legal, practical, civil and even human resource requirements needed?
In this episode of the Inside Line F1 Podcast, Soumil Arora spoke to Ben Wilshire and Dan Selby from Driven International, the company that was responsible for the most-recent changes to the Yas Marina Circuit (for the Abu Dhabi Grand Prix).
Driven International also designed the Hyderabad Street Circuit in India (for Formula E's Hyderabad ePrix), the Mandalika International Street Circuit in Indonesia (for MotoGP & Superbike World Championship) among others.
In Formula 1, the focus always is on car design, but in this April break, we decided to focus on circuit design. After all, Romain Grosjean famously said that it was cheaper to re-design circuits than the racing cars as the sport chased 'ease of overtaking'.
