The World Solar Challenge has finally released official results of the race (for Challengers, Cruisers, and Adventure class), and the chart below shows the breakdown of scores for the top five Cruiser class cars. As in my 2013 version of this chart, each coloured left-hand-side bar is the sum of the other four bars with the same colour.
The times used for scoring by the WSC are based, as far as I can see, on the time from Darwin to Adelaide (rather than to the so-called “end of timing” point) minus the waiting time at control stops and at Alice Springs. I suspect that Kogakuin might have won had they chosen not to recharge at Alice Springs (which would have slowed them down a little, but would have cost everybody else 7.5 points). As it was, Kogakuin’s speed advantage of 2.7 points almost exactly counterbalanced Eindhoven’s passenger advantage of 2.5 points, leaving practicality to decide the winner.
For comparison, here is the 2013 version of this chart. This year, the external energy use component decreased from 18.9% to 15%, the speed component increased from 56.6% to 70%, the passenger-carrying component decreased slightly from 5.7% to 5%, and the practicality-judging component decreased from 18.9% to 10%
