The NASCAR Sprint Cup Series begins the 2016 Chase for the Championship this weekend at Chicagoland Speedway and the running of the Teenage Mutant Ninja Turtles 400 and NASCAR getting tough on violations during the Chase.

FOX's Marghiee Teshineh has "FOX in the Fast Lane":

The field of 16 drivers has been set for this year's Sprint Cup Chase for the championship that starts this weekend in Chicago.

Defending champion Kyle Busch says winning the Cup two years in a row will not be easy:

(Busch) "As the No. 18 team, we've got some work to do. So hopefully we can figure those things out that we're missing, just key little components and get better."

Denny Hamlin says there is no way to predict how a driver will do in the Chase based on past performances:

(Hamlin) "Until you get to Chicago, look at practice, look at how the first race goes. that's kinda, to me the barometer of where we're really at."

And NASCAR announces tougher penalties for lug nut installation and post race laser inspections during the Chase. Penalties for having 17 or fewer lug nuts on a car or failing an inspection will cost a team 35 points and the services of his crew chief for three races, plus a $65,000 fine for the crew chief.
