AUSTIN, Texas — NASCAR is set to race the Circuit of the Americas for the first time and all eyes are on both Chase Elliott and an unsettling weather forecast of rain that could make the inaugural Texas Grand Prix a wild one.

Elliott, NASCAR’s defending champion and most popular driver, will start today as the favorite given his career mastery of road courses. And he needs a win. NASCAR’s season of parity has so far produced 10 winners through 13 races but none from Elliott.

Elliott’s been close with five top-five finishes and he was runner-up at the Daytona 500 and at Martinsville. He led a race-high 44 laps on the road course at Daytona but a late yellow flag ruined his chance at victory.

It may not be time to worry about Elliott’s season, but his Hendrick Motorsports teammates have all been to victory lane this year. Kyle Larson and William Byron have one win each, while Alex Bowman’s victory last week was his second of the season.

“I’m not one to guarantee things in my life,” Elliott said when asked this week if he’d expected to win by now. “We all want to win as a team. I want to win as much as anyone else. But we haven’t and that’s really the bottom line.”

In normal conditions, Elliott should feel as comfortable as anyone on a new track. His five career road course wins are the most among active drivers and he’s won four of the last five outings on road tracks.

If he wins a sixth race on a road course, Elliott would be just the seventh driver in history to reach that mark, tying him with Bobby Allison, Richard Petty, Rusty Wallace and Ricky Rudd.

But the dark cloud looming today is the likelihood of rain, which National Weather Service forecasts at better than 50%. The drivers slipped and slid their way through Saturday morning’s windy and wet practice session that may have been fun for some, but likely left none of them feeling comfortable about the race.

Joey Logano was second in practice, ahead of Kyle Larson and Kyle Busch. Busch and Martin Truex Jr. each have four road course victories.

Elliott, who was fifth in practice, admitted this week he doesn’t think he’s very good racing in wet conditions.

“The rain tire is certainly a bit of a question mark and it’s not one I’m very good at,” Elliott said bet. “Especially coming to a new track. (Rain) completely changes everything about the course and what you do.”

VEXING VISIBILITY

Byron and Logano said the visibility was next to zero on the track’s two high-speed straights because of the rooster tail of spray spit out by the cars ahead. That could be a factor if there’s more rain today.

“If you are going down the straightaway, you just trust the guy in from of you isn’t stopped,” Byron said. “If there’s a wreck on the straightaway, it’s going to be a mess.”

ALL RIGHT, ALL RIGHT, ALL RIGHT

Actor Matthew McConaughey will be the Grand Marshal for today’s race. It’s his second time in the role and the first since he gave the start command at the Daytona 500 in 2005. McConaughey is part of the ownership group of the expansion Austin FC in Major League Soccer. McConaughey’s name has also surfaced as a possible candidate for Texas governor in 2022.

ODDS & ENDS

Elliot is a 5-2 favorite to snag his first win of the season in the season’s first race in Texas, according to FanDuel Sportsbook…. NASCAR will be back in the state for the All-Star race weekend in June at Texas Motor Speedway in Fort Worth… Chris Buescher is the only Texas native who is a full-time Cup Series driver. He hails from Prosper, which is near Dallas… Byron has finished in the top 10 in 11 consecutive races, which ties him with Logano (2015) for the third-longest top-10 streak among active drivers.

Kyle Busch dominates Xfinity race

Kyle Busch turned in a dominating performance to win the NASCAR Xfinity race at the Circuit of the Americas on Saturday, with lessons learned for maybe an even bigger victory today.

Busch, looking to get some extra laps and much-needed track experience before the NASCAR Cup Series race, stepped into the Xfinity lineup and crushed the field from the pole position. He led 36 of 46 laps and finished 11 seconds ahead of A.J. Allmendinger for his record 98th Xfinity victory and 217th in NASCAR’s top three series. The win and the course knowledge will be a boost heading into today’s Cup race if conditions stay the same. But  Saturday’s race was dry.

Todd Gilliland rallies to win trucks race

Todd Gilliland powered through wet conditions early, then grabbed the lead late to pull away for his first NASCAR trucks series victory of the season Saturday at the Circuit of the Americas.

Gilliland was in a four-car group that drew from the pack at the start of the final stage, then overtook Sheldon Creed, Tyler Ankrum and Kaz Grala over the final laps. This was his second career trucks win and first since 2019.

“From the drop of the green flag, I was aggressive,” said Gilliland, who started fifth and overcame a penalty that briefly put him in the back of the field. “If you’ve got the truck to do it … you’ve got to get by people when you can.”

The victory also marked the first of any kind for a NASCAR series race at the Circuit of the Americas. NASCAR is racing at the 3.4-mile Formula One road course for the first time this weekend and doing it amid wind and rain.

None of it seemed to bother Gilliland, who won the first stage, then was penalized and pushed to the back when a crew member jumped the wall too early on his pit entry.
