The matter was brought up after the scandal at the Indianapolis 500 held earlier this year in May.During the race two of the three Team Penske cars were found violating the technical rules for illegal modifications. Brown also highlighted how, with the right amount of resources, IndyCar can gain the same amount of popularity as Formula One.While talking to RACER, the McLaren CEO showed interest in becoming a stakeholder at IndyCar alongside Penske and helping in popularizing the sport. Additionally, he also spoke about how IndyCar can benefit from a franchise system like Formula One.“I would love to see a true franchise system. If you think about NFL, MLB, NBA, F1 kind of – technically, they're not equity owners, but the way it's set up, I'd love to see that, because I think that then means the teams share and can take the same view. My annual P&L is one thing, but [if] the value of my IndyCar team has gone up, then you also have everyone rowing the same direction because everyone's sharing in the growth of the sport. It’s not my decision, but personally, I'd love to see that.” he saidZak Brown has been the most prominent factor in the turnaround of the McLaren Formula One team over the past few years. He managed to get huge sponsors like Google Chrome and DP World on board.
