Groove Meaning in NASCAR

The groove is the preferred path around a racetrack that offers maximum speed. Over time, tires leave a layer of sticky rubber on the asphalt surface. This rubber buildup provides more traction for cars following the same exact line. A driver who misses the groove often slides toward the outside wall. The veteran found a fast groove near the bottom of the concrete track. As the sun sets, the fastest path may move to a different area. Some tracks have multiple grooves which allow for side-by-side racing and passing. Finding the right lane is the most important task for a fast driver. A rubbered-in groove allows for much higher cornering speeds during a long run.
