Players battle AI drivers for race position for a preset number of laps.

As the race progresses, players are forced to make a pit stop to refuel, replace tires and repair damage.

For multiplayer support, NASCAR Thunder 2003 becomes split-screen and eliminates much of the field.

Returning from NASCAR Thunder 2002, it places the player in control of a custom NASCAR Winston Cup Series driver, who must manage pit crew, sponsorship and research and development for 20 seasons.

Players have a choice to play as either existing or custom drivers, and the settings are completely customizable, unlike the limited options in Career Mode.

Lightning Challenges are playable re-enactments of Winston Cup races from 1999, 2000, 2001, and the 1st part of 2002.

The player then has the chance to re-enact or alter history according to the particular scenario's requirement.
