The Championship 4 is set for the Cup, Xfinity and Truck Series and a champion will be crowned in each series this weekend at Phoenix Raceway.
The Cup season comes to a close Sunday on NBC and Peacock. An expanded Countdown to Green begins at 2 p.m. ET. followed by race coverage.
The Xfinity title race will be at 7:30 p.m. ET Saturday on the CW Network. The Craftsman Truck Series championship race will be at 7:30 p.m. ET Friday on FS1.
Here is a look at the four drivers racing for a championship in Cup, Xfinity and Trucks.
NASCAR CUP SERIES Denny Hamlin
Age: 44
Hometown: Chesterfield, Virginia
Cup championships: 0
Best points finish: 2nd (2010)
Crew chief: Chris Gayle
Team: Joe Gibbs Racing
2025 wins: 6 (Martinsville I, Darlington I, Michigan, Dover, Gateway, Las Vegas II)
2025 top-five finishes: 14
2025 top-10 finishes: 17
Championship 4 appearances: Fifth (2014, ’19, ’20, ’21, 25)
Outlook: Is this the year Denny Hamlin, who will turn 45 shortly after the season, claims his first Cup championship? Could it come in a year when 23XI Racing, a team co-owned by Hamlin and Michael Jordan is in a lawsuit against NASCAR that is headed for trial Dec. 1? Hamlin’s runner-up finish at Phoenix in the spring was the best result among the four championship contenders. He and his team have had two extra weeks to prepare for this race after winning the Round of 8 opener at Las Vegas. Three times in the last four years the winner of the Round of 8 opener has taken advantage of that extra time to win the Cup championship.

He has led a series-high 1,278 laps this season. He finished sixth at Phoenix in the spring, leading 83 laps. He looks to give the No. 24 car at Hendrick Motorsports its first Cup title since Jeff Gordon won his fourth and final crown in 2001.
