MostDece has written a superb blog post on the WSC challengers. Based on that, I’ve updated my previous post on dimensions. The infographic above (click to zoom) shows the reported length and width of 16 WSC cars (Challenger class only, this time). The widest car (at 2.05 m) is the South African car from NWU (below), but of course that includes the outrigger wheels. The narrowest is the long narrow bullet car from Michigan. There are also short zippy little cars from Nuon, Principia, and Punch.
Update: The chart below clusters cars with similar length/width combinations. NWU is a visible outlier. Below NWU, we have big cars (ITU, MDH, Adelaide, Aaachen, JU – over 1.6 m wide and at least 4 m long), short catamarans (Nuon, Principia, Punch – 1.55 to 1.6 m wide and at most 3.5 m long), narrow catamarans (Nagoya, Stanford, Twente, WSU – 1.38 to 1.5 m wide and at least 4 m long), and monohulls (Tokai, Kogakuin, Michigan – at most 1.2 m wide and over 4.9 m long):
Update: Unfortunately, the two charts above reflect incorrect information from the Stanford team. The Stanford car is actually substantially wider.
The infographic above (click to zoom) shows the reported length and width of eight World Solar Challenge cars. The widest car (at 1.8 m) is that of the Swedish MDH Solar Team (although this car has large bites taken out of each side). The two family Cruisers from Eindhoven and Lodz (dashed lines) are also quite wide, and take full advantage of the maximum allowed length of 5 m.
The Belgian Punch Powertrain Solar Team has produced a very short zippy Challenger class car (illustrated), and Nuon’s car (not shown) seems of a similar size. In contrast, Michigan has a long narrow bullet car, powered by GaAs solar cells. Twente, using Si cells, has a substantially longer car than Punch, but a narrower one. It will be very interesting to see how these differences play out in the race, come October.
The JU Solar Team, from Jönköping University (Sweden) ran into trouble in the 2013 World Solar Challenge, but they are back again in a new vehicle, and will hopefully do much better. Their new car weighs about 170 kg and has, they say, just 20% of the drag of a BMW 3 Series sedan. Good luck, team 46!
