The North American Solar Challenge is nearing completion - They are in Winnipeg, MB.
I was looking for some information regarding the cars (batteries, materials etc). Most of the website sites are quite light on real info.
Waterloo has some interesting info about their 3 wheeled car
Weight: 190 Kg empty
Batteries 30 Kg Kokam Lithium Ion Polymer
Frame: 6061-T6 aluminum tube with hybrid battery box
Motor: NGM 3 phase DC brushless
Body: kevlar, carbon fibre, nomex honeycomb
Solar Cells: 22% efficient Emcore Solar cells
Speed - cruising 80-100 km/hr
Speed - Top: 130 km/hr

The large-format Kokam lithium-ion/polymer batteries offer an energy density of 364 Wh/l to 377 Wh/l, and a recharge lifetime of more than 500 cycles at 80% DOD. If you ripped off the solar cells and just used this thing as a electric car it would fly!
