AUSTIN, TEXAS -- The Circuit of the Americas brought Formula One back to the U.S. with heavy doses of champagne, style and speed that put Texas on the map of world racing.

Now it's NASCAR's turn.

After several years of competing on the racing calendar with F1's annual stop in Austin, NASCAR brings stock car racing to a new road course where the drivers say they're excited to bump their way through the turns and s-curves carved out of rolling scrubland of Central Texas.

The 3.4 mile-track will put the drivers, most of whom have never taken a lap at COTA, through 20 turns, hard braking out of a long, high-speed straight, and a lefty switchback that slingshots the cars into a 133-foot descent just seconds after the start.

The Texas Grand Prix is one of a record seven road races on the NASCAR Cup Series schedule this season, park a weekend triple-header with lower-tier Xfinity and Trucks races.

"It's different than a lot of road courses we go to: very high-speed," veteran Cup driver Brad Keselowski said. "This section over here, it's about 185 mph. Then you slow down to about 30. You know, that's a heck of a ride; I know it would make my wife sick if she was riding with me."

While the world of F1 racing is all about finesse, NASCAR drivers expect to flex more muscle with their heavier, more durable cars. Contact is dangerous in open-wheel racing, but it's the norm for stock cars.

"I think all the things that don't make sense about our Cup cars will create some wild racing," said Tyler Reddick, who is among a handful of Cup drivers who will also be racing in the Xfinity Series on Saturday to get extra time on the track. "You're definitely going to see some drivers getting aggressive. We have heavy stock cars and can bounce off each other."

Add in a chance of race-day rain and things could get really wild. NASCAR fans can only ask what took so long to get here?

The Circuit of the Americas was built to race F1 cars. Since opening in 2012, it has hosted MotoGP, IndyCar and world endurance racing. The closest thing to resemble NASCAR was an Australian Supercars race in 2013.

NASCAR was a distant dream and the relationship between track owners wasn't always friendly. The Austin circuit was seen as a competitor with Texas Motor Speedway just three hours north in Fort Worth; some years, F1 and NASCAR raced on the same day.

Circuit of the Americas President Bobby Epstein credited Marcus Smith, head of Speedway Motorsports since 2015, with thawing the chilly relationship.

"I think it was a combination of the fans asking for it and the promoters listening," Epstein said. "He really took the initiative and said, `I think this would be good for the sport, our fans would like it' ... We found a way to be partners rather than competitors."

Smith signed a one-year lease to race at COTA, with an eye toward more races here in the future if this weekend is successful.

"This is the way it was done 50, 60 years ago in NASCAR when my dad first promoted races in the 50s, he rented a date from the local fairground's raceway," Smith said. "This is sort of a back-to-the future moment."

Measuring success this weekend is loosely defined. Race officials won't talk ticket sales other than to say they are ahead of projections, which had been adjusted down for expected smaller crowds amid the coronavirus pandemic. Few expect the crowds to approach the 100,000 or more F1 has reported for recent race weekends.

"Is it a fun and exciting race? That's No. 1," Smith said. "Do we sell the market? Our sponsors are happy. Our television partners are happy. I'm very optimistic NASCAR will feel like it had a great event."

NASCAR's road course experts think it will be.

Defending Cup Series champion Chase Elliott is still chasing his first victory of the season but has five career road course wins, including four of the last five. He will be among the favorites Sunday.

Martin Truex Jr. and Kyle Busch each have four road course victories. Busch is among those also in the Xfinity race on Saturday.

"I hope people will come out and give it a chance," Elliott said. "It's just a different type of racing. We're not going near as fast as those (F1) cars do ... but I do think the racing's better to watch, and I think that's what's made NASCAR popular over the years, and I'm not sure why that would be any different here."
