The 2008 Best Buy 400 was the thirteenth race of the 2008 NASCAR Sprint Cup schedule which was run on Sunday, June 1 at Dover International Speedway in Delaware's state capital, and serves as a fundraiser for Autism Speaks, with $5 from each ticket sold benefitting the charity. The race was the final NASCAR telecast on Fox for the 2008 season starting at 1:30 PM US EDT and on radio via MRN and Sirius Satellite Radio at 1:15 PM US EDT.
Greg Biffle earned his 5th Cup Career pole by qualifying first for the Best Buy 400, with a time of 23.193 and a speed of 155.219. Starting alongside him is Kurt Busch the 2004 NASCAR Sprint Cup Series Champion with a time of 23.381.
It was a major wreck in the early stages, sometimes known as "the Big One" on the backstretch, that claimed many of the front runners for the lead. This occurred when David Gilliland and Elliott Sadler touched, putting Sadler in the middle of the backstretch. When the smoke cleared, Kyle Busch, who has become one of the most beloved drivers among fans, won his fourth race of 2008.
