All-Electric or Plug-in Hybrid by Aptera
I'm not really into green/electric cars, but this one is too cool. The Aptera doesn't just look like it came from 'Back to the Future', it is the future. It comes in both all-electric and plug-in hybrid versions, and it's super aerodynamic (drag coefficient of 0.11, compare to 0.34 for Corvette Z06 or 0.26 for Toyota Prius; Hummer H2 is 0.57). The claimed fuel efficiency for the hybrid version is 230 mpg. Yes, that's 230 miles per gallon.
