This weekend, the spotlight will be on Lando Norris who makes his debut in IndyCar's iRacing Challenge, the McLaren driver joining a strong field of 33 cars at The Circuit of the Americas in Austin.
Norris spared no effort this week to get himself acquainted with IndyCar and up to speed, practicing for hours on end at home and with the help of his former McLaren performance engineer Andrew Jarvis.
On Saturday, other events will take place in the Formula E and All-Star Series arenas while NASCAR will hold its Sunday round at Talladega.
