AUSTIN, Texas (AP) — William Bryon started on pole and delivered a dominant drive Sunday to win NASCAR’s first road race of the season at the Circuit of the Americas. The Daytona 500 winner earned his second win of the season and delivered the fourth in six races for Chevrolet. The Hendrick Motorsports driver led 42 of 68 laps and held off hard-charging Joe Gibbs Racing’s Christopher Bell over the final two laps. Bell shaved nearly three seconds of Byron’s lead to create some late drama before Byron slammed the door over the final corners. Byron earned career win No. 12.

AUSTIN, Texas (AP) — William Byron won the Daytona 500 with an agonizing final lap under a caution flag. He took the checkered flag on Sunday at the Circuit of the Americas at full throttle.

Bryon started from pole position and delivered a dominant drive in NASCAR’s first road course race of the season. The Hendrick Motorsports driver led 42 of 68 laps and built the big lead he needed to hold off a hard-charging run from Joe Gibbs Racing’s Christopher Bell over the final two laps.

Bell shaved nearly three seconds off Byron’s lead to create some late drama before Byron slammed the door over the final corners.

“I was trying to not make mistakes,” Byron said. “I knew that last lap he was going to be pushing hard.”

Even when he was building the lead, Byron said he knew the victory would be tight at the end.

“Everyone is too good, and that car (was) too close,” Byron said.

A self-taught racer who used computer equipment to hone his skills, Byron earned career win No. 12 and his second on a road course.

The Circuit of the Americas, a track built for Formula One, has been the first road course for NASCAR each of the last four seasons. And unlike the crash-filled triple-overtime race of 2023, Sunday’s race was mostly incident free as Byron made easy work of the field.

Byron led 23 laps of the first two stages, but found himself quickly dropped to third at the start of the final stage as Ross Chastain, who won at COTA in 2022, jumped to the front.

Byron fought back to pass him with 25 laps to go and both cars pitted on the same lap. Chastain then got hung up in traffic on the re-entry and fell several cars behind.

That gave Byron the chance to open the gap he needed to keep Bell behind him at the end. Ty Gibbs, the 21-year-old grandson of team owner Joe Gibbs, finished third after getting passed by Bell with three laps to go.

“Another lap I would have gotten there for sure,” Bell said. “Passing (Byron) would have been difficult. I needed him to make a mistake and he didn’t make a mistake.”

PENALTIES

The course had few track limits, but the ones enforced by race officials brought a hefty penalty for drivers who got caught.

Chase Elliott, who won here in 2021 and leads active drivers with seven road course wins, was running sixth early in the final stage before driving out of bounds in the s-curve section of the racetrack.

That forced him do to a pit lane drive-thru and took him out of contention when he rejoined in 16th. Elliott, a former Cup Series champion, hasn’t won since 2022.

FORD FALTERS

Ford drivers have yet to win this season and did not expect big results on the road course. They delivered on the low expectations. Chris Buescher was the top Ford driver on Sunday in eighth.

COMING BACK TO COTA

The Circuit of the Americas is the only track to host both NASCAR and F1, and all signs point to the stock cars coming back next year.

Circuit of the Americas President Bobby Epstein said this week he has a deal for NASCAR to return in 2025, but provided no details. Marcus Smith, president of Speedway Motorsports, which runs the event and rents the track for the week, said he also plans a return.

“We love bringing NASCAR to Austin,” Smith said. “Nothing is final until the official NASCAR schedule comes out, but we’re planning for another big event in Austin at COTA in 2025.”

UP NEXT

The series moves to short track racing next Sunday at Richmond Raceway in Richmond, Virginia.
