Make the Future Detroit celebrates energy ideas

(WJBK) - Car designs of the future are racing through Detroit this weekend. Make the Future Detroit is a four-day festival that includes unique race that sees which team can go the furthest using the least amount of fuel.

Last year's winner went more than 2,500 miles on a single gallon of gas. FOX 2's Ryan Ermanni takes us to Cobo Center for a look at this year's teams.
