Finishing 31st in the season finale at Phoenix, McDowell and the team did not go out on a major high, however, it was still a significant event for the 39-year-old.
The race turned out to be McDowell's 500th race start in the Cup Series - a major milestone for the experienced driver.
For 2025, McDowell is set to join up with Spire Motorsport having agreed a multi-year deal with the team in May. As a result, McDowell will pilot the #71 car and drive alongside Corey LaJoie and 2024 Rookie of the Year winner Carson Hocevar next season.
Despite the excitement over the switch, there was certainly a touch of emotion in McDowell's words as he spoke about his exit recently.
"I thought about it like, man, it’s going to be a hard habit to break,” McDowell said ahead of the race in Phoenix, via NASCAR.
“I’m … just thankful, thankful for the opportunity I’ve had and what we’ve built and what we’ve done, and you know, there is a new chapter, and so I’m thankful for that.
"I’m thankful to still have a few years in front of me racing in the Cup Series, but it’s definitely going to be hard to walk away from the 34.”
