With the NTT IndyCar Series over for another season, work has already begun on the 2020 campaign.
Drivers Will Power and Scott Dixon took to the Indianapolis Motor Speedway on Wednesday to give the Aeroscreen its track debut.
The device is set to be on all of the cars from next season onwards, so Dixon and Power put the screen through its paces.
Motorsport Week has put together a gallery of the day's historic occasion.
