Low Groove

Low Groove is the racing line closest to the inside edge of a racetrack, typically representing the shortest path around a corner or through a turn.

In motorsport, drivers constantly search for the fastest way around a track, and this optimal path is called "the groove." The Low Groove runs along the bottom portion of the track, near what's called the apron or inside edge. While this inside line covers the least distance, it's not always the quickest route.

The effectiveness of the Low Groove depends on several factors. Track conditions play a huge role - sometimes debris, loose dirt, or small rubber pieces called "marbles" accumulate on the inside line, reducing tire grip. Weather conditions like temperature and moisture also affect which groove works best.

During a race, drivers might start by testing the Low Groove to see if their car handles well on that line. Some cars are set up specifically to work better on the inside, while others perform better running higher up the track. The fastest groove can actually change throughout a race as track conditions evolve.

When commentators say a track is "one-groove," they usually mean everyone is forced to use either the Low Groove or high groove because only one line is fast. This makes passing difficult since drivers can't use alternative routes. Multi-groove tracks offer more racing lines, creating better opportunities for overtaking.

You'll often hear drivers say things like "I couldn't get my car to work in the Low Groove today" or "The bottom came in during the second half of the race." This language describes how the inside line became faster or slower as conditions changed, forcing drivers to adjust their racing strategy accordingly.
