Kevin Magnussen is set to add NASCAR to his racing CV. Trackhouse Racing has confirmed that the former Formula 1 driver will make his NASCAR Cup Series debut in the team's Project91 entry at the inaugural San Diego street race at Naval Base Coronado on 21 June.
Magnussen will pilot the No. 91 Chevrolet backed by Qualcomm, which joins the project as primary partner and as the official circuit partner for the San Diego weekend. The technology company is also linking up with Trackhouse behind the scenes, supplying artificial-intelligence tools through its Dragonwing on-prem appliance to help the team's competition staff process real-time data and sharpen in-race strategy calls.
For the 33-year-old Dane, the outing is the latest twist in a career that has taken him from a decade in Formula 1 to sportscars. Magnussen currently races for BMW in the World Endurance Championship, where he recently took a podium at Spa, and the chance to sample stock-car racing on a brand-new street circuit clearly appealed.
"I'm incredibly excited and honoured to have the opportunity to compete in NASCAR," Magnussen said, adding that he has "already spent time with the team" as he prepares for a very different challenge to anything in his single-seater and prototype background.
Project91 is Trackhouse's standalone programme for bringing international stars into the Cup Series, and it has carried plenty of star power since its launch. Magnussen becomes the fourth driver to race the No. 91, following two-time Formula 1 podium finisher and 2007 world champion Kimi Raikkonen, Supercars great Shane van Gisbergen and four-time Indianapolis 500 winner Helio Castroneves, whose 2025 Daytona 500 start was the most recent outing for the entry.
"We were waiting for the right opportunity with the right partner and driver to bring this Project91 entry to fruition," Marks said.
The setting could hardly be more fitting for a one-off spectacle. The San Diego race, held on a temporary circuit at Naval Base Coronado, is one of the most eye-catching additions to NASCAR's 2026 calendar, and a street layout should suit a driver with Magnussen's road-racing pedigree. Whether a Cup rookie can be competitive against seasoned stock-car racers on debut is another matter, but Project91 has form for delivering eye-catching results, most notably when van Gisbergen won on his Cup debut in Chicago.
For Magnussen, the appeal is straightforward: a fresh challenge, a high-profile platform and the chance to test himself in a discipline far removed from the worlds of Formula 1 and endurance racing that have shaped his career so far.
