The Ultimate Guide To The NASCAR Xfinity Series Championship: 5 Key Changes You Need To Know For 2025
The NASCAR Xfinity Series Championship remains one of the most intense and unpredictable events in motorsports, a true 'winner-take-all' spectacle that caps off a grueling season of competition. As of December 19, 2025, the racing world is buzzing not only about the dominance of the most recent champion, Justin Allgaier, but also about the significant, fresh changes that are redefining the series for the 2025 season and beyond, most notably a landmark shift in its broadcast home.
The 2024 season was a masterclass in consistency and late-season performance, culminating in a dramatic finale at Phoenix Raceway. However, the focus has now pivoted to the 2025 campaign, which promises a new era of visibility and a continued high-stakes playoff structure that ensures only the absolute best driver is crowned champion. The action is set to conclude once again at the Arizona short track, but the journey to get there will look drastically different for fans and competitors alike.
Driver Profile: Justin Allgaier (2024 Champion) and Connor Zilisch (2024 Regular Season Champion)
The 2024 season saw two distinct forms of excellence rewarded, with veteran consistency finally translating into a title, while a young phenom announced his arrival with a record-tying run.
Justin Allgaier: The Veteran's Title Triumph

He holds the all-time record for most top-10 finishes in Xfinity Series history, surpassing 292.

The 2025 NASCAR Xfinity Series Championship Race: Date, Location, and Format
The structure of the championship remains one of the most compelling aspects of the sport, offering a high-pressure, single-race showdown. The 2025 season will once again conclude with the decisive event at the iconic one-mile tri-oval in Arizona.
Championship 4: Winner-Take-All
The championship is determined by a playoff system that begins with 12 drivers competing across three rounds: the Round of 12, the Round of 8, and the Championship 4.
- Playoff Structure: After each three-race round, four drivers are eliminated based on their points total or by winning a race in that round.
- The Finale: The final four drivers who survive the elimination rounds advance to the season finale. The highest-finishing driver among these four in that specific race is crowned the NASCAR Xfinity Series Champion, regardless of their performance throughout the rest of the season. This "winner-take-all" format guarantees maximum drama.
The 2025 Finale Details
The race date is a crucial piece of information for any fan planning their calendar.
- Date: Saturday, November 1, 2025
- Location: Phoenix Raceway, Avondale, Arizona
- Distance: 200 Laps / 200 Miles
- Stages: The race is typically divided into three stages, with the 2024 race being 45/45/110 laps.
A New Era of Visibility: The CW Network Broadcast Deal
Perhaps the most significant and *freshest* development for the 2025 season is the massive shift in the series' media rights. After years of coverage by FOX and NBC, the Xfinity Series has found a new exclusive home, which will dramatically change how fans watch the races.
Exclusive Rights to The CW
Beginning in 2025, The CW network will become the exclusive broadcast partner for the entire NASCAR Xfinity Series season.
- Duration: The CW secured a seven-year deal for the exclusive broadcast rights, running from 2025 through 2031.
- Impact: This marks a major push into live sports for The CW and is a pivotal moment for the Xfinity Series, which will now have a single, dedicated broadcast partner for the entire season, including the crucial Playoff and Championship races.
- Comcast Partnership: Despite the broadcast change, Comcast renewed its decade-long partnership with NASCAR, ensuring the series will retain the "NASCAR Xfinity Series" name and continue its role as a Premier Partner.
This new media rights deal is part of a larger restructuring of NASCAR’s broadcast landscape, which includes FOX Sports, NBC Sports, Amazon's Prime Video, and TNT Sports covering the Cup Series. However, the Xfinity Series stands alone with The CW, giving it a unique platform for growth and visibility.
