The UCI Energy Invitational has competitors run on a course that combines highway, autocross and metered idle sections with only $1.00 of the energy of their choice.  This year six entrants competed on May 23, 2010.   Teams from UC Irvine, UC Davis and Cal Poly Pomona formed the collegiate class, and an inventor’s electric three-wheeler, a first generation Honda Insight and a Smarte Car formed the enthusiast class.
