Stewart-Haas Racing's Kevin Harvick will have the chance to defend his NASCAR Sprint Cup Series championship next weekend at Homestead-Miami Speedway.

The 2015 NASCAR Sprint Cup Series season is down to the final race, the Ford EcoBoost 400 at Homestead-Miami Speedway. Four drivers will head to South Florida this weekend looking for a title, but only one will win it.

Here are five reasons why Kevin Harvick will leave Homestead with a second consecutive title.

Speed: It all starts with fast race cars, and Harvick's No. 4 Stewart-Haas Racing Chevrolet has been Freaky Fast since he first tested with the team in late 2013. You don't post 14 top-two finishes in a season without fast cars.

Chemistry: Every top team has good equipment. The best teams also have great chemistry. Without question the combination of Harvick, crew chief Rodney Childers and the No. 4 SHR has been extremely potent. And the team is even stronger this year than it was in their final season.

Ability to overcome obstacles: One of factors that truly differentiates the No. 4 car from the field is the ability to overcome obstacles. At Texas, for example, Harvick lost a tire and had his shifter repeatedly jump out of gear, forcing him to hold it in place and steer with one hand at 180 miles per hour. And yet, he managed to finish third, a gutty and gritty performance. The No. 4 team has been far from error-free, but they have an amazing ability to work through their issues.

Pressure performer: When you absolutely, positively have to win a race, there's no one better at it that. Facing elimination in the final race of the last two Chase rounds in 2014 and the first round this year, Harvick won all three times. That's just flat incredible.

Been there, done that: Three drivers and their teams believe they can go to Homestead and win a championship. But only Harvick and his team know they can take the title because they've done it once already. That's a huge advantage.
