Brabham drove Ryan Hunter-Reay’s DHL car on a filming day for the squad, and enjoyed his step up from his regular ride with the Andretti squad in Indy Lights.

“It was a fantastic day as I can finally say I've driven an IndyCar,” said Brabham. “Even though it was just for commercial filming purposes, it just made me really want to race one even more.

“The IndyCar felt like it had a lot more downforce than any other car I have driven, and to drive one on the limit must be awesome.”

Brabham, 21, drove the car on Thursday, which would have been his grandfather Sir Jack’s 89th birthday, at the oval formerly known as Indianapolis Raceway Park.

He became the first Brabham to drive an IndyCar since his father Geoff raced at the Indianapolis 500 in 1993.

The outing puts the Brabham family alongside the Andrettis in that they have both had three generations pilot a version of North America’s premier open-wheel racecars.

Brabham and his team are currently working to secure funding for the remainder of the 2015 Indy Lights season, while also looking at the option of a limited IndyCar Series campaign.
