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.
Before the World Solar Challenge, I made up up some posters of personal picks (below, click to zoom). How did I do? The top five Challengers these year were indeed as in 2015, although in a different order. Eindhoven and Bochum indeed look like they will be first and second in the Cruisers (although Sunswift, with their car problems, did less well than I expected).
Among my “dark horses,” Western Sydney improved on their 2015 result to come 6th (making them Australian champions!) and Kogakuin’s radical design came 7th. Aachen did not do as well as I expected; nor did the South African car. Stanford look like they might come 11th, but none of my speculative Cruiser picks made the top 3 (which makes me sad; I like those cars even more now I’ve seen them up close). At the time I made the picks, Arrow had not revealed much information, so I did not anticipate how strong their Cruiser debut would be. Congratulations to them and to all the teams!
The chart above (click to zoom) is another of my classic race charts for this year’s race. Five Challengers have arrived, and two more are expected tomorrow afternoon. The chart 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 (that’s a substantially slower baseline than I used in 2015). The 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). Open coloured circles show simplistically extrapolated arrival times.
Update Friday: Aachen (70) still seems to be in the race. Guestimates for Cruiser arrival times are given as coloured squares. Unfortunately the WSC web site is misbehaving again, so there are no reliable control stop times for today.
On the morning of Day 5, Nuon is still powering along. There should be full sun at least until Port Augusta. The map above (click to zoom) shows GPS positions extrapolated using GPS time lag and the average speed since the start of the race. The table below shows team numbers, raw road distance from Darwin, average speed, extrapolated road distance, class (or number of seats for Cruiser class), team name, and team social media links.

Based on data from the WSC web site, the chart above (click to zoom) shows Challenger-class timings. 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 (that’s a substantially slower baseline than I used in 2015). 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).
Open coloured circles show simplistically extrapolated arrival times. For example, I would expect Nuon to arrive a little after 2 pm Darwin time (3 pm Adelaide time) tomorrow. The rest of the top five should arrive later in the afternoon, or early Friday morning. All the other Challengers are potentially in trouble, but it’s impossible to say for certain.
The grey stripe on the right (11:00 to 2:00 on Friday) shows the permitted Cruiser class arrival window. Eindhoven (40) and Bochum (11) are on track to arrive inside this window. Arrow (30) and HK IVE (35) will do so if they speed up a little. Minnesota (94) and Apollo (95), travelling at 60 km/h and 58 km/h respectively, are in serious trouble, timewise.
The chart above (click to zoom) shows Cruiser scores as at Kulgera (which lets us compare apples with apples). Each team has three coloured bars: first the number of person-kilometres, which should be large (black icons show occupied seats and white icons empty seats), then the energy usage, which should be small (number of charges, which is 4, times battery capacity), and finally the overall score, which should be large again (it is the ratio of those first two numbers). The black number inside the final bar shows the ranking. All bars are scaled to a percentage of the maximum, because the exact numbers do not matter – only the relative relationships. The rule for the final score bar is: first bar divided by second bar, then scale so that the largest result is 80%. The practicality score (out of 20) will be added to that final result.
Challengers and Cruisers in the WSC are strung out from Alice Springs to Glendambo. The map above (click to zoom) shows GPS positions extrapolated using GPS time lag and average speed. The table below shows team numbers, raw road distance from Darwin, average speed, extrapolated road distance, class (or number of seats for Cruiser class), team name, team social media links, and links to pictures or status reports.
