264 MPG? Yep, in a Volkswagen vehicle that's experimental but not all that far-fetched. Their goal was only 235 MPG -- or, in terms practical for their engineers, 100 km per 1 litre. And they achieved it - in the real-world conditions shown above.
The VW is extremely light, at 639 pounds, but does include ABS and driver's airbag. (There is a passenger seat - right behind the driver.) It'll even do 75 MPH (120 km/h). The gas tank carries about a gallon and a half of diesel.
