10 Tokai University Solar Car Team (Tokai Challenger)
The team from Tokai University won the World Solar Challenge in 2009 and 2011, after four straight Nuon wins. In 2013, however, Nuon fought back, leaving Tokai in 2nd place. Since then, Tokai has won the 2014 Carrera Solar Atacama and has come 7th in the Abu Dhabi Solar Challenge. This year, they are no doubt hoping to recapture first place in the WSC with their new car (above and below). Technical details of the vehicle (in Japanese) are here. In particular, they report solar cells of 23.2% efficiency. Good luck, team 10!
