It’s “Heim Time” in the Nascar Cup Series.

Corey Heim, 21, is 23XI Racing’s reserve driver. Now, he will have a shot at competing in the team’s third part-time entry. The team, co-owned by Michael Jordan and Denny Hamlin, will field the No. 50 Toyota at Nashville Superspeedway with Heim behind the wheel.

Mobil 1, which signed an expanded deal with Toyota Racing Development this year, will be the primary sponsor on the No. 50 car.

“I’m very thankful for this opportunity I’ve been given by Mobil 1 to compete with 23XI in Nashville,” Heim said in a statement. “Through my time with Toyota, I’ve had the opportunity to meet so many amazing people, including those from Mobil 1.

“We have seen this season how strong 23XI’s Camrys have been, which makes me even more excited to get behind the wheel in Nashville. I’m putting in the effort to be prepared for this opportunity and cannot wait to get on-track with the No. 50 Mobil 1 Toyota team in a few weeks.”

Heim replaced Erik Jones with Legacy Motor Club in the No. 43 car for races at Dover and Kansas. Jones suffered a compression fracture after a wreck at Talladega. Heim finished both of his Cup Series starts with Legacy. He finished on the lead lap at Kansas, coming home in 22nd.

“We are excited for Corey to join the 23XI team in Nashville as he helps us celebrate our partners at Mobil 1 and its 50^th anniversary,” Steve Lauletta, president of 23XI Racing, said. “Corey is undoubtedly an up-and-coming star, and we look forward to working with him as he prepares to race at Nashville. Mobil 1 has a history of working with some of the best young talent in racing, and I can’t think of a better person than Corey to drive the No. 50 Toyota at Nashville.”

Heim is considered to be one of the top prospects in Nascar. He has seven Craftsman Truck Series wins. This year, the Tricon Garage driver has two wins and has finished all eight races inside of the top 10.

Heim is expected to be in contention for a Cup Series seat as early as 2025.
