NASCAR track lengths vary from half a mile, all the way up to more than 2.6 miles. Homestead-Miami Speedway is one and a half miles around, which is why so many people think Martin Truex Jr. will end up celebrating a victory on Sunday.

The #78 car was the fastest car in Saturday afternoon’s practice session, and also had the fastest car on the mile and a half tracks this season. Of the 11 races that took place on 1.5 mile tracks, Truex won 6 of them.

“This track is much different from the mile and a half tracks we’ve won on," Truex said. "With that being said, our car has been fast every weekend, no matter where we’ve been.”

That consistency is why Truex enters the championship race as the favorite, and he and the Furniture Row Racing team embrace that role.

“I just think it’s the best position to be in. I think you want to be the guy that’s dominated the season, the guy that’s won the most races, the guys that’s led the most laps," Truex told 9NEWS. "Everybody knows that we’re going to be tough to beat.”

In the old format, Truex would already be the season champ. But NASCAR recently made the move to this game-seven like, winner take all race to finish the season with drama.

“I did think about it a little this week," Truex said. "Just knowing how many great champions this sports has seen over the years, I could’ve joined a lot of them last week if it was formatted like it was a couple of years ago.”

“I think that’s kind of a cool accomplishment either way," Crew Chief Cole Pearn said, "I don’t think anyone had clinched early in the old format, and we would have done that this year. That’s something to be proud of for some and speaks to how great a season we had.”

One more solid performance on a 1.5 mile track and Truex will be bringing NASCAR's championship trophy to Denver.
