Since 1934, soap box derbys with homemade race cars would take place in neighborhoods and communities, letting youngsters showcase their innovative design efforts.

Fast forward to 2011. With electric vehicles becoming more popular forms of transportation due to consumers wanting to lighten their carbon footprints, the soap box derby is also receiving a 21st century makeover. Forget the gravity-powered racers of days gone by, because today's tech-savvy youth are building their own racers that utilize alternative forms of energy.
