Based on data from the WSC web site, the final race chart above (click to zoom) shows Challenger-class timings (for the cars that did not trailer). It is drawn with reference to a baseline speed of 83.89 km/h. This is the speed that would complete the race (to “end of timing”) in 4 days and 5 hours. The left vertical axis shows how far behind the baseline cars are driving. Straight lines represent cars driving at a consistent speed. The right vertical axis shows arrival time at “end of timing” in Darwin time (Adelaide time is an hour later). The twists and turns of the lines here reveal many of the dramatic events of the race, such as the spate of bad weather. The chart below shows average speeds.
