As a one day event, the ability to store energy in the batteries will be reduced, and the efficient use of solar energy will be key. The American Tour de Sol is a yearly competition organized by the Northeast Sustainable Energy Association. Production electric cars, buses and motorcycles built by car manufacturers compete alongside student-built electric cars, hybrid electric cars, and sleek one person solar racing vehicles from around the country and abroad. Each day, the vehicles are required to drive 60-70 miles. The scoring system makes efficiency and driving range the key to winning.
Speed is a factor, however, as there is a restricted amount of driving time.
Range, capabilities, and efficiency are measured and acknowledged. Brain Sport - Documentary of the 1996 World Solar Challenge.
