Kevin Harvick's Las Vegas NASCAR win 'answers questions' for 2018

Harvick's victory at Las Vegas made it two wins in a row for the 2014 Cup champion after winning at the unrepresentative Atlanta race the week before.

He believes winning at a more conventional NASCAR track means he can better judge his 2018 prospects.

When asked if his start to the current season reminded him of his title-winning campaign, Harvick said: "For me, there was a lot of questions coming into the weekend.

"Atlanta is its own beast, but we answered a lot of those questions for ourselves [at Las Vegas].

"And now it's about navigating the rest of it, and how do you push yourself forward, what do you need to work on, even though things are going good.

"Sometimes you have to trick yourself and everybody else into thinking, OK, well, everything is going good.

"Well, I can promise you that the #78 [Martin Truex Jr], the #18 [Kyle Busch], the #2 [Brad Keselowski], the #22 [Joey Logano], everybody is going to work, and they're going to get better.

"We've been in this position before, and you have to keep pushing forward to try to keep your advantage of things that are working well for you, but you also have to find out what your weaknesses are."

SHR has had a strong start to the 2018 season with Aric Almirola narrowly defeated at the Daytona 500 before Harvick's two wins.

Harvick explained that its improved form is down to becoming more comfortable running with Ford machinery, having switched from Chevrolet for 2017.

"These guys at Stewart Haas Racing have worked on Chevrolets for a long time [2002-16], and that's the only car that they knew," he said.

"So learning the nuances of a different manufacturer and, I think as you look at the second year for us, last year when we put the engine in the car, none of the steering components worked.

"You had to redesign the steering, you had to redesign the clips, you had to redesign the motor mounts, and then it was just one problem after another.

"As you come into this year, all those things work, and you're working on the small nuances of a new inspection process and different things that come with that and whatever the little rule changes were, the pit road stuff.

"Last year we weren't able to focus on anything for the first four months because everything was a problem. Everybody knew that.

"The only reason that it didn't stick out like a sore thumb is because we have a lot of good people and owners and a manufacturer that gave us the resources and finances to go out and solve those problems."
