Corey Heim gets a head start on Cup Series life. The 23XI Racing prospect will run part-time in NASCAR's premier class during 2026 before moving up full-time in 2027, giving him crucial reps against the best competition before he officially makes the jump.
This is a smart development strategy. Rather than throw Heim into the deep end cold, 23XI is letting him acclimate gradually. He'll split time between his current rides and Cup Series equipment, learning the nuances of faster cars, tighter fields, and veteran competition without the pressure of a full schedule hanging over his head immediately.
Heim has impressed in lower series racing. The staged approach reflects 23XI's confidence in him and their willingness to invest in his development. Getting him meaningful Cup experience in 2026 means he arrives in 2027 with real knowledge of what the job demands, not just theoretical understanding.
It's a blueprint more teams should follow with young talent. Too often prospects jump straight up and struggle. Heim will have the runway he needs. If he performs in these part-time races next year, he'll have real data backing his full-time move in 2027.
