The Science of Racing: Gear Ratio Activity

Published on 08/17/2011

Activity Overview

Tracks on which Sprint Cup Series races occur vary in length, banking and surface among other things. On all tracks, proper set up to handle the turns is critical to team success but this is especially true for short tracks. For both NASCAR and T80 SRC drivers, as a driver negotiates a turn, the car decelerates as it enters the corner then accelerates back up to top speed when it exits the turn. How fast your car can accelerate is greatly dictated by the gear set.
