313 Miles Per Gallon. Sign Me Up.

From inhabit.com:

Volkswagen just unveiled a new car at the Qatar Motor Show that gets an astounding 100km for less than a lieter of diesel fuel – that’s the equivalent of 313 miles per gallon! The green car is an upgraded version of the VW L1 vehicle and it features an ultra-efficient diesel engine in addition to an electric motor that is powered by a lithium-ion battery.

Production is said to begin in 2013. I wonder if my Prius can hold out that long…
