In NASCAR, clean air is key.

Austin Dillon used the clean air to dominate Saturday's Hisense 300 from Charlotte Motor Speedway. Dillon led 163 of the scheduled 200 laps on his way to his second victory of the Xfinity series season.

The victory is Dillon's first Xfinity win at Charlotte and his fourth in the series overall.

"The car was so good I didn't want to get out of it," Dillon told reporters in Victory Lane. "It was a heck of a race at the end with Denny (Hamlin) and Kasey (Kahne). I had to go when we got in lapped traffic. I knew the tires might go, and I might not make it happen."

Dillon started from the pole, led 183 laps and won earlier this season at Las Vegas. All four of his wins have come when starting on the pole.

The 25-year old North Carolinian knows winning in front of the home crowd is a big deal.

"It's huge," Dillon admitted. "I talked to Bob (Pockrass) earlier in the weekend about North Carolina drivers that are still in the sport. I know in the Cup series there are only two of us, me and Junior. I got my brother coming up in the Xfinity. It's huge for our North Carolina boys to take home our trophy in our state, so it's very special on Memorial Day weekend, also. Very pleased; a lot of friends and family here.

"It's a special moment for sure."

The race's final restart on lap 166 saw Denny Hamlin, driver of the No. 54 Monster Energy Toyota, challenge and take the lead from a dominant Dillon. Hamlin was able to lead 19 laps but ultimately took the checkered flag with a second place finish.

Hamlin, who won $1 million dollars last week at Charlotte in the Sprint All-Star Race, knew beating Dillon would have been a tall task.

"Those guys have got some fast cars," Hamlin said. "You do your best to try to hold them off, but similar to when I ran in this No. 54 car at Vegas, Austin (Dillon) was just two, three tenths faster than the field and those RCR cars are strong and you just as an organization you've got to get a little bit better. So you learn and see where you need to get better."

Kasey Kahne, driving the No. 5 Armour Chevrolet for JR Motorsports, ran up front for most of the race and finished in third place. Regan Smith and Darrell Wallace, Jr, rounded out the top five finishers. Austin Dillon's brother Ty Dillon finished in sixth place.

Regan Smith, Darrell Wallace, Jr, Daniel Suarez, and Ty Dillon all qualified for this season's edition of the "Dash4Cash" program, which is a program designed to be a unique competition between Xfinity series championship eligible and could allow for a driver to win $1 million dollars.

Ty Dillon won big in last season's edition of the "Dash4Cash".

"It's an awesome program Xfinity is putting back on," Ty Dillon said. "I think everybody in the offseason was real worried that the series might go away, but I think everybody's jacked up again. I was fortunate enough to win it last year when I won Indianapolis, and it's a huge added bonus for everybody."

Last week's winner at Iowa, Chris Buescher, finished in 11th and maintained his Xfinity series points lead by just four points over Ty Dillon. Last season's Xfinity Champion Chase Elliott is 28 points back in third as the series heads to Dover next weekend.
