The revamped knock-out qualifying format will make its inaugural appearance in the NASCAR Sprint Cup Series for Sunday’s race in Phoenix. As long as the weather permits, two of NASCAR’s national series will complete qualifying for the first time under the new format. Last week at Daytona, the NASCAR industry excitedly awaited the arrival of knock-out qualifying for the NASCAR Nationwide and NASCAR Camping World Truck Series, but rain cut short NNS qualifying and completely cancelled the truck series session. Qualifying for the Daytona 500 did not change from years past.
