Five Indy NXT teams will use Monday’s full-day test at the Indianapolis Motor Speedway road course to assess 11 prospective drivers, with British single-seater standout Abbi Pulling and George “G3” Argyros III among the names drawing the most attention.

The session, scheduled for Sept. 21 and running from 11 a.m. to 5 p.m. ET, gives teams a valuable opportunity to compare young drivers in a controlled environment at one of North America’s most important racing venues. For drivers hoping to move up the ladder, Indy NXT tests can be just as important as race weekends: they are often the first chance to show speed, technical feedback and adaptability directly to a team’s engineering staff.

Andretti Global Gives Pulling a High-Profile Platform

Andretti Global will evaluate Pulling, who arrives at Indianapolis with a growing reputation in formula cars. The Alpine Academy driver has been one of the more closely watched prospects in single-seaters, and her presence on the entry list makes this test especially notable.

Pulling’s background matters here because Indy NXT teams are not simply looking for raw lap time. They want drivers who can handle the physical demands of the cars, work through setup changes and learn quickly on a road course that rewards precision. A strong showing in a test can open doors even when there isn’t an immediate race seat available.

Andretti Global has long been one of the more recognizable organizations in the U.S. junior formula landscape, and its willingness to evaluate Pulling reflects the broader interest in identifying talent outside the traditional IndyCar pipeline. The test also gives her another chance to demonstrate how her single-seater experience translates to the Indy NXT platform.

George Argyros III Adds a Different Kind of Spotlight

Argyros, better known in racing circles as George “G3” Argyros III, is another driver whose name stands out on the list. While Pulling brings an established single-seater résumé, Argyros represents the kind of prospective entrant teams often want to sample in a testing environment before deciding whether to invest further time and resources.

That mix is part of what makes these evaluation days useful. Indy NXT serves as a proving ground for drivers from different backgrounds, and an open test lets teams compare prospects on equal footing. A fast lap matters, but so do consistency, communication and the ability to absorb engineering direction over the course of a long session.

Why the Indianapolis Road Course Test Matters

The Indianapolis Motor Speedway road course is a logical venue for an Indy NXT evaluation because it mirrors several of the demands drivers face during the championship season. It combines long straights, braking zones, loaded corners and plenty of opportunity for setup sensitivity to show up quickly. A driver who can adapt there is usually giving a team useful information about how they might perform across a broader range of circuits.

The five-hour test window also gives engineers enough time to work through tire degradation, balance changes and traffic management rather than relying on a handful of hot laps. For a category built around developing future IndyCar talent, that kind of session is far more revealing than a simple speed contest. Teams can watch how a driver builds pace, responds to coaching and handles the ebb and flow of a real race program.

What Indy NXT Teams Are Looking For

Prospective drivers in Indy NXT are judged on much more than outright pace. The cars are demanding, the schedule is compressed and the margin for error is narrow. Teams will typically want to see several specific traits during a test:

• Speed over a single lap
• Consistency across longer runs
• Clear technical feedback
• Adaptability to setup changes
• Professionalism in and out of the car

That broader evaluation is part of what makes a day like this meaningful even before a contract or race entry is on the table. A driver can improve their stock without necessarily setting the fastest time, simply by showing they can work methodically with a team.

A Useful Snapshot of the Driver Market

An 11-driver evaluation spread across five teams offers a decent snapshot of how Indy NXT continues to function as a feeder series. Teams are not only searching for the next standout; they are also building their bench for future seasons and looking at drivers who may be ready for partial programs or an eventual full-time step up.

For Pulling, the test is another chance to move from prospect to serious candidate in a series that has become increasingly relevant to young drivers trying to reach IndyCar. For Argyros and the rest of the entry list, it is an opportunity to make an impression in front of people who can turn a strong day into a seat, a program or a longer-term conversation.

On a day set aside for evaluation rather than racing, that is the real prize: not headlines from the timing sheets, but the chance to show that speed and composure travel well beyond a single lap.
