2001 Protection One 400

The 2001 Protection One 400 was a NASCAR Winston Cup Series stock car race held on September 30, 2001, at Kansas Speedway in Kansas City, Kansas. The race was the 28th of the 2001 NASCAR Winston Cup Series season. The race was the inaugural Cup race held at the 1.5 mi track. Jason Leffler from Chip Ganassi Racing won his first career pole position with a qualifying speed of 176.499 mi/h. Penske Racing's Rusty Wallace led the most laps with 117, while Jeff Gordon of Hendrick Motorsports won the race.

Due to the September 11 attacks happening earlier in the month, the Federal Aviation Administration (FAA) ordered a no-fly zone, prohibiting aircraft from flying within three miles of any sporting event area, which also includes an altitude of 300 feet. To increase security, coolers and large bags were banned from the track, At the same time, other items like purses and binoculars were subject to inspection. Meanwhile, in the sense of patriotism after the attacks, Sterling Marlin ran a "God Bless America" paint scheme, which had not been prepared in time for the 2001 MBNA Cal Ripken Jr. 400 the week before. To support victims of the attacks, Marlin's sponsor Coors Brewing Company donated $10 for every lap completed at the race by Marlin.
