3.纯电动

    纯电动车（EV）完全不需要汽油；它们用电池蓄电来驱动汽车。这种车三年前才推向大众市场，此后大家才开始慢慢接受它，现在对它的需求则开始日益增长，下至低端市场中现在售价已降为3万美元的日产聆风（Leaf，见上图），上到出乎意料大受欢迎、价格高达8万美元的特斯拉Model S。对续航里程的担心还是阻碍更多消费者购买它的主要原因，同时大城市外充电站数量极为有限也是一个很大的障碍。2013年市场上共有主要厂商生产的11款不同纯电动车在售，其中就有梅赛德斯出品的电动版斯玛特ForTwo（Smart ForTwo），它号称每充一次电的续航里程达到68英里，促销打折前的售价为20,740美元。

    3. Electrics

    Electric vehicles (EVs) run gasoline-free; they use a battery to store the electric energy that powers the motor. Acceptance of pure EVs has been slowly growing since they were introduced to the mass market three years ago, with increased demand both at the low end of the market, following price cuts on the $30,000 Nissan Leaf (above), and at the top with the surprising success of the $80,000 Tesla Model S. Range anxiety continues to be a deterrent to greater buyer interest, as does the limited number of charging stations outside major cities. Eleven different EV models from mainstream manufacturers were on sale in 2013, among them Mercedes's Smart ForTwo Electric, which claims a range of 68 miles per charge and sells for $20,740 before incentives and discounts.
