Corey Heim Is Making It Impossible for NASCAR to Ignore His Cup Series Potential

Corey Heim started near the back of the field at Phoenix Raceway and finished fifth, delivering another impressive performance in a part-time Cup Series opportunity with 23XI Racing.

While Tyler Reddick celebrated in Victory Lane and the NASCAR championship standings were being turned upside down, another 23XI Racing driver was quietly putting together one of the most impressive performances of the afternoon. Corey Heim started Sunday's Freeway Insurance 500 from 36th position and climbed all the way to fifth, gaining 31 positions at a racetrack where clean air and track position can make passing particularly difficult. The performance continued a growing trend for Heim, who has repeatedly demonstrated an ability to overcome poor starting positions and compete against established Cup Series drivers despite having significantly less experience in the Next Gen car.

Heim's performance was especially impressive considering how difficult the opening portion of the race appeared to be for the No. 67 team. Starting near the back meant spending much of Stage 1 trapped in traffic, where dirty air made it challenging to demonstrate the car's actual speed. As the race progressed, the team began making adjustments and using pit strategy to create opportunities for Heim to run in cleaner air. Once those opportunities appeared, he began consistently improving his position, eventually working his way into the top 10 before finishing inside the top five.

The result was not simply the product of late accidents eliminating cars ahead of him. Heim had to navigate traffic, manage his tires and adapt to changing track conditions throughout the 312-lap race. Phoenix's combination of heavy braking, relatively flat corners and difficult passing opportunities creates a technical challenge that can expose inexperienced drivers. Heim handled those demands well enough to finish ahead of several championship contenders, including Joey Logano, Chase Briscoe, Ty Gibbs and Denny Hamlin.

The performance also continued a trend that Here For The Speed has been following throughout the season. During our Phoenix podcast, we discussed how Heim seems to make a habit of starting deep in the field during his Cup appearances before steadily working his way toward the front. At Charlotte one week earlier, Heim started 37th and finished 11th. Phoenix followed with an even stronger result, reinforcing the idea that his ability to adapt to the Next Gen car is becoming one of the most interesting development stories in NASCAR.

There is an important distinction between having the talent to race competitively in the Truck Series and demonstrating that the same skills translate directly to Cup competition. The cars behave differently, the competition is substantially stronger and the aerodynamic challenges become more demanding when drivers are racing against teams with years of development experience. Heim has already established his abilities in NASCAR's lower divisions, but performances like Phoenix provide evidence that his talent is capable of translating to the highest level.

His association with 23XI Racing also makes this development particularly interesting. The organization has established itself as a legitimate winning program with Reddick, and having Heim deliver a top-five finish in a part-time entry strengthens the case that the team possesses competitive equipment beyond its primary cars. Reddick's victory and Heim's fifth-place finish gave the organization two cars inside the top five, a significant achievement considering the quality of the field and the championship pressure surrounding the event.

Heim still has plenty to prove before anyone can declare that he will become a consistent Cup Series winner. Running well in selected races is different from competing for points over an entire season, particularly when the schedule includes superspeedways, road courses, short tracks and intermediate ovals. A full-time opportunity would require him to demonstrate the same consistency across every type of racetrack rather than simply producing impressive results during individual appearances. However, those questions cannot be answered until a driver receives enough opportunities to prove what he can do.

The biggest challenge for Heim may eventually become finding a seat that allows him to demonstrate his potential on a regular basis. NASCAR has no shortage of talented young drivers searching for opportunities, but very few arrive with the combination of lower-series success and encouraging Cup performances that Heim is beginning to build. Starting 36th and finishing fifth is the kind of result that should attract attention from organizations evaluating their future driver lineups.

At Phoenix, Tyler Reddick proved that 23XI Racing could still win races when the championship pressure was building.

Corey Heim proved something different.

He looks increasingly ready for a much bigger opportunity.
