IndyCar’s October Test at Indianapolis Gains Star-Studded Lineup

Mick Schumacher and Caio Collet headline an expanded field for the upcoming IndyCar Series test on the Indianapolis Motor Speedway road course on October 13, marking key development runs ahead of the 2026 season.

Monday’s IndyCar test at the Indianapolis Motor Speedway road course is shaping up to be a highlight of the offseason, featuring an expanded and impressive entry list. Mick Schumacher, the former Formula One driver and son of Michael Schumacher, will take his first laps in an IndyCar with Rahal Letterman Lanigan Racing. This marks a major step for Schumacher, who has transitioned to endurance racing with Alpine but remains eager to test his skills in America’s premier open-wheel series.

Joining him is Caio Collet, who will be running a second test with AJ Foyt Racing as he pushes for a race seat. Collet showed promise during his first outings and continues to build experience on some of the toughest circuits.

The test will also feature other promising talents and reserve drivers across multiple teams including Andretti Global and Chip Ganassi Racing. It’s a crucial opportunity for teams to fine-tune setups and get valuable data ahead of the 2026 season. Drivers and engineers alike will be using the challenging 2.439-mile, 14-turn road course to prepare for what promises to be another fiercely competitive year.

For Mick Schumacher, this test offers a chance not only to adapt to a radically different racing machine but also to prove he can still compete at the highest levels. For Collet and others, it’s a shot to stake their claim, aiming to secure a coveted IndyCar ride. With so much talent on display and so much at stake, this test is more than just laps and setups — it’s the starting line for the future stars of IndyCar.

That’s Monday at Indy: a day packed with anticipation, speed, and the promise of a new era in American open-wheel racing.
