| Unknown track | SM | 1 | +4.350s (3.62%) | +4.350s (3.62%) |
| Unknown track (2.59 mi) | SM | 5 | +5.161s (4.28%) | +4.350s (3.62%) |
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.
