There are also practice and qualifying settings. Practice enables car setups to be altered and tested in real time. Choosing not to participate in the qualifying session results in one starting at the back of the field. The qualifying session requires four laps to be completed, with the mean value of the four lap times determining the qualifying position. No car damage can occur during a Practice session, although other cars may be present on the track and their wreckage remains on the track if the player's car collides with them at any point. Car damage can occur during qualifying sessions. The cars one can drive are a yellow Penske-Chevrolet, a red Lola-Buick, or a blue March-Cosworth, with the Penske having the fastest default setup (but if one sets the car up well, any of the above racecars can compete effectively). Various settings can be changed during Practice from menus associated with Function keys F3–F10. One's own car is always numbered 17.
