In a city where its citizens love their cars and the independence they provide there are a few ultra efficient vehicles cruising thru downtown this weekend.

Considering mass transit rail and the METRO bus system lackluster ridership these mass transit options will never be embraced by the majority of the population anytime in the near future, the only real option to provide more sustainable motility is hybrid electric and other sustainable forms of solar and bio-diesel powered vehicles.

View these vehicles at the Shell Eco-Marathon this weekend at Discovery Green in Downtown.
