You aren’t supposed to win the Coca-Cola 600 from 40th place. It just doesn't happen.
In a race that spans 600 miles and 400 laps—the longest, most grueling test of man and machine on the NASCAR calendar—track position is usually king. If you start at the back, you're fighting "dirty air" and the risk of getting caught in someone else's mess for hours. But on May 25, 2025, Ross Chastain didn't just break that rule. He shattered it.
The nascar results coke 600 fans saw at Charlotte Motor Speedway weren't just a list of names; they represented a historic "worst-to-first" charge that hadn't been seen in the modern era. Chastain, driving a backup car for Trackhouse Racing after a nasty practice crash, hunted down William Byron in the final laps to secure his first win of the 2025 season.
It was a night of pure endurance. And for Byron, it was a heartbreaking loss after leading a staggering 283 laps.
The Impossible Climb: How the No. 1 Car Ended Up on Top
The story of the race actually began on Saturday. Chastain blew a tire in practice, sending his primary Chevrolet into the wall and forcing his crew to pull out the backup. Because they missed qualifying, he was relegated to the very last spot on the grid. 40th.
Honestly, most people had written him off before the green flag even dropped.
But the Coca-Cola 600 is a marathon. Chastain and crew chief Phil Surgen played the long game. While William Byron was busy sweeping the first three stages—looking absolutely untouchable in the No. 24 Hendrick Motorsports Chevy—Chastain was methodically picking off cars. He wasn't flashy. He just stayed out of trouble and kept the fenders clean.
By the time the fourth and final stage rolled around, the track had changed. The sun was down, the air was cool, and the grip levels shifted. This is where the magic happened.
The Final Sprint
With about six laps to go, Chastain found himself within striking distance of Byron. Byron was struggling with a "tight" race car, likely a result of the changing track conditions and the heavy workload he’d put on his tires all night.
Chastain made his move entering Turn 1 on Lap 395. He dived low, slid up in front of Byron’s bumper, and took the lead. He crossed the finish line 0.673 seconds ahead of Byron.
It was a masterclass in patience.

Behind the drama of the lead change, the rest of the field was a chaotic mix of survival and strategy. Here is how the front-runners shook out after 600 miles of racing:

Ross Chastain took the checkered flag, followed immediately by William Byron who had dominated nearly 70% of the race. Chase Briscoe, who started on the pole, managed to recover from a pit road penalty early on to finish a solid third. A.J. Allmendinger and Brad Keselowski rounded out the top five, with Keselowski notably grabbing his first top-10 of the season.
The back half of the top 10 featured some familiar heavy hitters. Chase Elliott came home sixth, with Michael McDowell in seventh. Christopher Bell, Ryan Preece, and Noah Gragson filled out the remaining spots.
It's worth noting that Ryan Preece and Noah Gragson both had incredibly quiet but effective nights, staying out of the multi-car wrecks that claimed several big names.
Heartbreak and High Stakes: The Drivers Who Didn't Make It
While Chastain was celebrating with a smashed watermelon on the finish line, several championship contenders were left wondering what went wrong.
The biggest "what if" belongs to Kyle Larson. Larson was attempting the "Double"—racing the Indianapolis 500 and the Coca-Cola 600 on the same day. He crashed out of the Indy 500 on Lap 91, which actually allowed him to get to Charlotte earlier than expected. However, his luck didn't improve in North Carolina.
On Lap 245, a five-car pileup in Turn 4 ended the nights for Larson, Ryan Blaney, and Daniel Suarez. For Blaney, the defending series champion at the time, it was a massive blow to his playoff points cushion.
A Rough Night for the Legends
Jimmie Johnson’s 700th career start was another headline that ended in the garage. On Lap 112, his Toyota broke loose in Turn 4, collecting Cole Custer and the young phenom Connor Zilisch. It was a disappointing end to a milestone night for the seven-time champion.
Then there was Carson Hocevar. He was arguably the fastest car on the track during practice and was running in the top five for much of the evening. His engine expired on Lap 307, leaving him with a "Did Not Finish" (DNF) despite a performance that proved he belongs at the front of the pack.

With this victory, Ross Chastain became the eighth different winner in the first 13 races of the season. In the current NASCAR format, a win basically guarantees you a spot in the playoffs. Considering Chastain had been hovering around the cutline before Charlotte, this win changed the entire trajectory of his season.
- Playoff Lock: Chastain is in.
- Momentum: Trackhouse Racing proved their backup cars are as fast as their primaries.
- Points Shake-up: William Byron, despite the loss, walked away with a massive haul of stage points (winning Stages 1, 2, and 3), keeping him at the top of the regular-season standings.
Final Insights for the Fans
If you're looking at the nascar results coke 600, the biggest takeaway is that endurance racing is as much about the shop floor as it is about the driver. Chastain’s crew worked until 2:30 AM on race morning to get that backup car ready. They were back at the track by 5:30 AM.
That kind of grit is what wins crown jewel races.
For those following the rest of the season, keep an eye on the "long-run" speed. Byron was a rocket on short bursts, but Chastain’s car came alive after 40 laps on a set of tires. As we head into the summer months with hotter tracks, that long-run stability is going to be the deciding factor at places like Nashville and Darlington.
If you want to stay ahead of the curve, start tracking tire fall-off stats. The teams that can keep their cars from getting "tight" in the final 10% of a race—like Chastain did—are the ones who will be holding the trophy in Phoenix come November.
