The most jarring sign of trouble came in Thursday night's second practice when the Dutchman was a dismal 17th on the speed chart compared to Norris, who was among the top three fastest drivers in both sessions.

The problem?

Red Bull apparently made an incorrect adjustment to the rear wing of its car at Las Vegas and GPS data showed its two cars to be significantly slower on the straights than both McLaren and Mercedes, which led both practice sessions with Lewis Hamilton. The Red Bull rear wing is adjustable and was set to give the team more straight-line speed. While that worked, it compromised other aspects of the car.

The team believes the issue has been resolved ahead of Friday night practice and qualifying.

Verstappen, however, proved two weeks ago in Brazil that adversity is nothing he can't overcome. He started 17th on a wet and rainy circuit and still managed to win his first race since June by nearly 20 seconds.

Verstappen, whose eight wins this season are his fewest since 2020, has not won back-to-back races since Canada and Spain in June. But the Brazil win widened his lead over Norris in the standings to 62 points and the championship is his barring a complete collapse over the final three races.

He is not sure what to expect Saturday night.

“I just want to focus on the weekend and try to have a good performance. Brazil was a very welcome victory for us after a while, but this is again very different,” said Verstappen, who won the inaugural Las Vegas Grand Prix last year.

Prior to discovering the rear-wing issue, Verstappen felt decent about his chances in Las Vegas.

“Three races left, you're getting close to the end of the season and it's looking good in the championship, but we still need to score a lot of points so we'll just focus on that,” he said. “Once we are doing that then you get closer to the end result.”

Norris was admittedly downtrodden after Brazil, where he started on the pole but finished sixth and lost ground to Verstappen after first cutting the lead to 44 points by winning the sprint race.

“This was almost a defining moment for the championship. It was a defining moment for the championship. The doors are almost shut," Norris said. “For a week, I was pretty down because I had that realization of things pretty much out of my control now, not within reach necessarily. That's a tough realization when your hopes and belief are so high. For it to get knocked down so much all of a sudden was pretty demoralizing.”

Even so, Norris is convinced he will one day be F1 world champion.

“I have what it takes,” Norris said. "I think it's the first time in the last six years of F1 when we've had a chance to fight at the front. This is our, and my, first opportunity to do so, and my first opportunity to see where I stand. I definitely was not at the level I needed to be at at the beginning of the year.

“I still need to make tweaks and I still need to improve on things, that's clear. I'm not completely satisfied with how I've done and I definitely know I need to make improvements," he added. "But, for the first time, I'm confident to say I have what I think I need to fight for a championship.”

Norris has the first three wins of his career this season and has McLaren currently atop the constructor championship standings. He knows he's got more work to do to be champion, especially against Verstappen.

“It doesn't mean I'm complete, it doesn't mean I'm perfect. When you're competing against drivers who are close to that, like Max, you have to be close to perfect if you want to challenge him,” Norris said.

McLaren is still clinging to a 36-point lead over Ferrari in the battle for the constructor championship, a title worth a bonus estimated to be $150 million.

McLaren last won that title in 1998, while Ferrari last won in 2008. Red Bull has won the last two titles. Ferrari could chip away at McLaren's lead at Las Vegas.

“Ferrari have been strong for a long time,” said Norris. “They have two very good drivers, they're a very good team, they've clearly improved their car a good amount and found a better direction to head down. We do know that Vegas is probably a track that will suit the Ferraris a bit more, it suited them well last year, but Qatar we know maybe will be more favorable to us.”

Carlos Sainz Jr., in his final three races for Ferrari before he is replaced by Hamilton and moves to Williams, wants to close his tenure by helping the team win the constructors title.

“I would love to win the championship for Ferrari this year,” Sainz said. “I think it would be a great way to sign off the season."

He predicted that McLaren will be stronger in the final two races of the year, at Qatar and Abu Dhabi. But at Las Vegas? Sainz expects he and teammate Charles Leclerc to be stronger.

“This (track) is more Ferrari than McLaren, but at the same time, the temperature is notgame of thrones slots, so we'll see how it pans out,” Sainz said of temperatures expected to be in the 40s Fahrenheit (5-10 degrees Celsius) on Saturday night. (AP) AM AM
