In this week’s episode of The Inside Line, IndyStar motorsports reporter Nathan Brown and co-host Joey Barnes discuss Andretti Global’s dominant Detroit Grand Prix weekend that led to Kyle Kirkwood’s second win of 2025. The pair also dig into the ins and outs of Santino Ferrucci’s post-race tech inspection penalty, Zak Brown’s comments about needed changes in IndyCar, the TV ratings and what they mean and look at who might still be alive for a championship push other than Alex Palou.
