Corey Heim's Masterclass in Patience: How Part-Time Racing Prepares a Prodigy for the NASCAR Cup Series

Why this matters: In a sport where young drivers are often rushed into top-tier competition, 23XI Racing is demonstrating a patient, data-driven development model. For fans and aspiring racers, Heim's journey offers a blueprint for how to prepare for the biggest challenge in motorsports without burning out or stalling early.

The Part-Time Blueprint

Corey Heim's 2026 schedule might seem unusual for a defending champion. After dominating the Truck Series with 12 wins in 2025, one might expect an immediate full-time Cup promotion. Instead, 23XI Racing designed a transitional year: 12 Cup Series starts, a handful of Truck races, and relentless off-track preparation.

"He's pretty much as involved as a full-time driver," Heim told ESPN. "I work out there every day, and I do the simulator two or three times a week. I pretty much prepare as if I'm a full-time driver in case something happens to one of their guys and I have to sub in at the last second."

The Mindset Shift

Heim's turning point came after a frustrating 15th-place finish at Kansas Speedway in April. He had a car capable of much more but struggled with decision-making — where to position himself, when to take risks. Dave Rogers, 23XI Racing's senior director of competition, pulled him aside afterward.

The message was simple: stop racing for points and start racing for lessons.

"It's OK if you take these bigger risks and learn," Rogers told Heim. "No one is going to think poorly of you if you hit a wall... We want you to be ready for 2027 and learn from mistakes."

This philosophy shift has been transformative. Heim now focuses on filling his "notebook" with experiences rather than chasing every position.

Toyota's Long-Term Investment

Toyota Racing Development (TRD) first flagged Heim in 2017-2018 when he was running late models against their factory drivers. After a successful seven-race ARCA trial in 2020, they signed him. By 2021, he was winning six ARCA races. The progression to Trucks confirmed his elite potential.

TRD president Tyler Gibbs praised Heim's preparation habits: "He is so serious about his preparation, the questions that he asks. From that perspective, what he learned from Kyle Busch when he was racing Kyle and constantly asking Denny questions, all of those things show his desire to compete and get better."

Historical Context

Heim's path mirrors other greats who benefited from measured development. Unlike drivers rushed into Cup rides who flamed out, Heim will arrive in 2027 with hundreds of hours of simulator work, wheel-force data analysis, and real Cup Series experience from 12 starts — plus the psychological freedom to have made mistakes along the way.

When will Corey Heim debut full-time in the Cup Series?

Heim will drive the No. 35 car full-time for 23XI Racing starting in the 2027 season, alongside Tyler Reddick and Bubba Wallace.

Why isn't Heim racing full-time in 2026?

23XI Racing is using 2026 as a development year. Heim runs 12 Cup races, a handful of Truck starts, simulator sessions 2-3 times per week, and wheel-force testing for Toyota. The focus is on learning, not results.

What did Dave Rogers tell Heim after Kansas?

Rogers told Heim it was acceptable to take bigger risks and make mistakes, as long as he learned from them. The goal is preparation for 2027, not perfect finishes in 2026.

How did Denny Hamlin discover Heim?

Hamlin noticed Heim's race craft years ago, comparing his instincts and decision-making to those of Tyler Reddick. He knew he needed to bring Heim to 23XI Racing.

How many Truck Series wins does Heim have?

Heim earned 21 Truck Series wins over three seasons (2023-2025), including 12 wins in his championship 2025 season.
