The gasoline / battery-powered hybrid car, for example, can travel 20 kilometers on one liter of gasoline, fuel efficiency that is far higher than the 12 to 15 kilometers per liter of gasoline achieved by regular cars. This greater fuel efficiency can significantly reduce carbon dioxide emissions, but how can a vehicle costing NT $ 1.3 million gain widespread adoption?
以「油電混合車」為例，1 公升的汽油可跑 20 公里，燃油效率比一般汽車高 4 成，可降低不少 CO2 的排放，但是目前一輛 130 萬元的高價，如何普及？
