Even fewer World Solar Challenge teams have reported the weight of their vehicle than have reported their solar cell efficiencies, but 7 teams have. The histogram below plots these reported values, ranging from 136 kg to 182 kg. Around 160 kg (the weight for Nuon and Tokai) seems to be typical. For comparison, a Formula One car weighs about 700 kg (including the driver), and a Volkswagen Beetle weighs about 800 kg. But, although some teams have worked very hard to minimise weight, this is not where the real competition seems to be.
