Kyle Busch wins final NASCAR Cup race on two-mile oval at Auto Club Speedway

As farewells go, it was chilly. And weepy.

The Fontana air had a pronounced chill Sunday for the last NASCAR race on the venerable two-mile Auto Club Speedway oval, less than 24 hours after snow improbably blanketed much of the Inland Empire.

The track wept, and that isn’t an attempt at personification. Trapped rainwater from the last few days seeped from under cracks and seams in the porous, 26-year-old asphalt, forming what drivers call “weepers” — slick, wet spots that can cause a driver to lose control, especially when tire treads become worn.

But the track was drivable, and competitors can read it and weep: Kyle Busch won going away.

Who could be surprised that the veteran took the last Auto Club 400? It was his fifth victory in the race, including his first Cup Series win in 2005 and his 200th overall win in 2019.

Chase Elliott finished second with a strong final 30 laps and was followed by Ross Chastain and Kevin Harvick.

Crews got to work Sunday before 6 a.m. to stem the tears, employing enormous track-drying apparatuses — Air Tundras, Buffalo Turbine Blowers, Jet Dryers and a sweeper truck. They also used hand saws and drills to create troughs in the track where water could drain from outside banks to the apron.

The Cup Series race started on time at 12:30 p.m. in front of a sellout crowd of about 50,000, and the drivers lined up five wide during pace laps before the drop of the green flag, an impressive sight meant to salute the fans that supported the 2-mile track since it opened in 1997.

Alex Bowman, who led early for 16 laps, girded for what he envisioned as the worst-case scenario, although he couldn’t help from making a track-tears joke.

“The track is definitely going to be sad because it’s getting torn down, so it’s obviously going to weep,” he said before the race. “The straightaways have gotten super rough here, so if you’re dodging things down the straightaway, the car is going to get pretty difficult to drive, even in a straight line.”

Weepers weren’t the worst problem with the track. By lap 40, the front of cars looked like they’d been sandblasted, and pit crew had to be mindful not so slip on debris that shook out of grills during stops.

Chastain won the first two points stages, after 70 and 140 laps, and was riding momentum. He won at Circuit of The Americas and at Talladega Superspeedway in 2022, but his most memorable moment came at Martinsville Speedway in October when his audacious move passing two cars on the last lap was christened the “Hail Melon” because Chastain is an eighth-generation watermelon farmer.

On the final lap, Chastain needed to pass two cars. He floored it going into Turn 3 but instead of relying on the tires for turning force, Chastain used the wall to help him turn much faster. His lap time of 18.845 seconds was the fastest ever for a stock car at Martinsville.

NASCAR quickly passed a rule forbidding the wall-riding maneuver. It would have been impossible to employ at Fontana anyway because the wall banks aren’t severe. Chastain led for 71 laps, gave way to veterans Kyle Busch and Harvick with 62 to go, then regained the lead seven laps later.

In his last season as a Cup Series driver, Harvick was making his 750th consecutive start, making him the third driver to reach the milestone. He and Busch — who are tied among active drivers with a record 60 Cup Series wins — were first and second with 62 laps to go.

But an aggressive move by Chastain pushed back Harvick for good and Busch momentarily. Busch slipped to seventh, but quickly moved back to second, hanging right on Chastain’s tail.

Busch was not to be denied the final victory on a two-mile oval beloved by drivers.

Although until the new track breaks ground NASCAR could abandon the project, the plan is to reduce the track from two miles to a half-mile and modernize the speedway so that races appeal to a broad demographic, not just hardcore NASCAR fans.

NASCAR confirmed Friday that it has sold most of the Auto Club Speedway land to its business partner Hillwood, a Dallas-based company that is helping NASCAR sell properties nationwide. NASCAR will retain 89 of the more than 500 acres and says it will continue with plans to develop the half-mile track.

Kyle Larson, last year’s Auto Club 400 winner, had an engine issue after only a handful of laps and trailed by 15 laps by the time he got back up to full speed.

The sixth caution came after several cars spun out into the infield on a restart. Leader Joey Logano didn’t speed up as fast as expected going into the green flag and everyone behind him squeezed in like an accordion. It prompted the largest wreck in a Cup Race in history of the Auto Club Speedway and sent to the sidelines Christopher Bell, Tyler Reddick, Ryan Preece, Aric Almirola and AJ Allmendinger.

“I think the leader was just playing games, trying to prevent the runs coming from behind and they stopped in the middle of the restart zone right about where they should have been accelerating,” Almirola said. “Everybody just started stacking up and you can’t stop on a dime. It’s disappointing to get wrecked out of the race like that on a silly Mickey Mouse restart, but I should have known better.”
