Against the front of the class, by track and class
| Track | Class | Sessions | Typical gap to class best | Closest |
|---|---|---|---|---|
| Michelin Raceway Road Atlanta (2.54 mi) | FE2 | 5 | +4.635s (5.43%) | +3.338s (3.94%) |
| Michelin Raceway Road Atlanta (2.54 mi) | SRF3 | 4 | +3.857s (4.05%) | +2.174s (2.27%) |
Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.
