Gizmag article about Urbee 2

http://www.gizmag.com/urbee-2-transcontinental-us-10-gal/29716/
It gets 5.26 miles per kilowatt hour for the batteries.  Estimated 40 mile range for 7.6 kWh batteries.
IC engine can run on diesel or ethanol.
No EPA mileage rating.  The 300 miles on a gallon isn't verified.
Author says 50k price point may be optimistic.

Update:

I've run some numbers on the power requirements and so forth.  300 miles per gallon seems far-fetched.  There's just so many joules in a gallon of diesel fuel.  Measuring the rate in which it uses up the kilowatt hours in the battery, it doesn't appear likely that it can get 300 miles on a gallon.  They are going to have to fudge this a bit, but how would they do it?  Drive slowly and stop often for recharges!

Update:

I may have made some errors in my calcs.  I am skeptical about the 300 mpg figure, that's all.  Not trying to discredit the work.
