5 Youngest active IndyCar drivers in 2025 ft. Nolan Siegel

IndyCar has been putting itself on the world map slowly but surely. Every time a young racer takes to the wheel in the American open-wheel car racing series, a new fanbase is born. The young blood promises to carry on the legacy left by the retiring greats and infuse new life into American motorsport.

The 2024 IndyCar series saw equal participation by the younger contingent and the more experienced drivers. Out of 28 drivers, fourteen were aged 28 or younger, while the older half comprised drivers between ages 31 and 44.

On the 2025 grid (where four seats are yet to be filled), while the number of drivers under 28 is still fourteen, the older set has been reduced to nine drivers. Let's take a look at the five youngest drivers who will line up on the IndyCar grid next year (rounded off to the nearest month).

2024 was David Malukas' third year in IndyCar. However, his year began at a shocking low. On 11th February, a month before the season started, he injured his left wrist, requiring surgery. As a result, Arrow McLaren released him citing the lack of a return date to racing.

Unsurprisingly, a driver of his caliber couldn't go unsigned. Once he recovered, Meyer Shank Racing signed him for the remainder of the season, beginning with the Grand Prix of Monterey on June 23. Malukas finished P24 in the standings with 148 points to his name - a step down from 265 points and P17 in 2023.

In 2021, Malukas finished second in the Indy NXT with a series-record 16 podiums. He is also a multiple-karting champion.

In 2025, Malukas will race for Aj Foyt Racing in their Chevrolet-powered Dallara. The Chicago-born driver will be 23 years and 5 months old at the time of the first race weekend next year.
