15 drivers are all preparing for the NASCAR's Sprint Cup Series championship-crowning season finale at Homestead-Miami Speedway on Nov. 16.

Most of the drivers who are vying for the championship are coming from powerhouse team including Hendrick Motorsports to Team Penske to Stewart-Haas Racing and Joe Gibbs Racing and all of them are getting ready for the race.

The next time they will see each other in the said racetrack is for the race itself.

According to Penske's Brad Keselowski "You have to enter Homestead with the expectation that you need to win the race to win the championship and we have two cars and teams who are in the hunt for that."

Adding "It's really a very, very critical test not just for us, but for all the teams. I look forward to coming back here because three of the last four times [here] we've celebrated a championship in some form whether it was Cup or Nationwide."

But before the main event, there are still a couple of races to finish including his week's stop at Texas Motor Speedway. This race will decide which four drivers will advance to the Championship Round of the Chase for the NASCAR Sprint Cup at Homestead-Miami.

Penske's Joey Logano said "You have to execute the next couple races first, but that's why you see so many cars testing here. It all comes down to Homestead. Making sure you have a fast car here is important. That's going to be the difference in winning the championship or not. Most likely, you're going to have to win here to win the championship this year, or come close to it."

For Keselowski, playing safe is not an option. He said "All the cars are fast but we want to be the fastest of the fast. For us, that's the key thing for us here today. You can't really practice pit stops or restarts. What we're looking for when we test is one element of the weekend, how much raw speed does you car have."

"Speed is the building block for a successful winning team and the most definitive way to find that speed is what we're doing here with testing."
