Except the claims comparing mileage to the Prius are based on different standards. Saying this prototype gets 84 highway or whatever is the same thing as the Elio claiming the same thing. Put it in through a modern day EPA cycle the Prius is rated on and I doubt it beats it. Also now add modern crash standards and emissions and I doubt it beats a Mirage.

Just for comparison the 2017 Cruize diesel gets 77mpg on the old style highway EPA test and that still includes acceleration and deceleration. Put the Cruize at steady state 55mph speed limit on 1982 and I bet it beats the 81 mpg with modern emissions and safety. And you can buy it!
