Dillon's 2020 season started with him DNFing at that year's Daytona 500, finishing 30th. The next week at Las Vegas, Dillon finished 10th, his first top 10 at a non-plate track. For The Real Heroes 400 at Darlington, he'd start 33rd, determined after a random draw, and finish 19th. The starting positions for the upcoming Toyota 500 would be determined by inverting the top 20 finishers of The Real Heroes 400, giving Dillon a spot on the front row starting 2nd, alongside Ryan Preece. At the YellaWood 500 at Talladega on October 4, 2020, Dillon originally crossed the line and tied his best finish of fourth, but when Matt DiBenedetto was penalized for forcing someone below the yellow line, Dillon was promoted to third and that would be a new career-best finish for him. In Germain Racing's final season, Dillon finished 26th in the points standings.^[41]

On September 22, 2020, it was announced that Germain Racing would shut down after the 2020 season due to lack of sponsorship from Geico, and would sell their charter that guarantees the car would drive in every race in a season to the newly-formed 23XI Racing, led by Michael Jordan and Cup driver Denny Hamlin.
