Technically, though, the four-passenger carbon fiber aircraft isn’t really an electric plane but more of a plug-in hybrid plane, much like the Chevrolet Volt. Whatever it is, the Volta Volare aeronautics company of Portland, Oregon says the plane can travel 300 miles on battery power, then a 1.5-liter gasoline engine engages and extends the plane’s range to 1,000 miles. The company sees the plane being attractive for its low cost of operation and its environmental friendliness. Aviation gasoline (avgas) is typically leaded fuel, which has been gone from motor vehicle fuel since the 1980s. On a 200-mile trip in a comparable four-passenger gas-engine private plane, you’d burn $80 worth of avgas, while the electricity to carry the GT4 200 miles would cost only $20 — nice savings, but perhaps a little inconsequential when the plane itself is expected to cost around $500,000. Testing begins this spring on the Volta Volare GT4."
