NASCAR 2005: Chase for the Cup is the eighth installment of the EA Sports' NASCAR video game series. It was developed by EA Tiburon and released on August 31, 2004 for PlayStation 2, GameCube, and Xbox. NASCAR 2005 is the first game in the series to drop the word Thunder from the title since NASCAR 2001. Kevin Harvick, driver of the No. 29 GM Goodwrench Chevy Monte Carlo, appeared on the cover replacing Jeremy Mayfield who was originally to have been on the cover and removed completely from the game. It also marks the first time the original PlayStation has been excluded from the NASCAR lineup. This was the first NASCAR edition to be released exclusively on sixth generation home consoles.

The NASCAR Whelen Modified Tour (NWMT) is a modified stock car racing series owned and operated by NASCAR in the Modified Division. The Modified Division is NASCAR's oldest division, and is the only open-wheeled division that NASCAR sanctions. NASCAR Whelen Modified Tour events are mainly held in the northeastern United States, but the 2007 and 2008 tours expanded to the Midwest with the addition of a race in Mansfield, Ohio. The tour races primarily on short oval paved tracks, but the NWMT also has made appearances at larger ovals and road courses.
