Looks reasonable - it is front wheel drive, but there are no details on the engine. It reminds me of a tandem Zap or the Myers Duo.
Ultra High Mileage Car : Elio Motors
No specs that I could find, other than it is FWD, has an 8 gallon tank, and comes in a choice of 7 colors...
They are saying it is a motorcycle, so if your state requires a motorcycle license, you will need one. Though, you will be able to take your driving test in the Elio, so no worries. Massachusetts requires a motorcycle license.
The price would be a breakthrough - I hope they can do it. Apparently the $100 deposit is
nonrefundable, so I think prudent skepticism is in order. I hope they are legit, and come out with more technical details, and how they tested for the 84mpg claim, etc.
