雪佛兰Volt

    Volt在今年年初重磅登场，风头直追Lady Gaga。这款车型先后收获了好几个年度汽车奖，通用公司（GM）大胆的技术飞跃似乎要把全世界的热情都点着了。可惜的是，Volt的电池在某些事故情况下存在隐患，加上今年年中Volt的生产曾出现长达一个月的中断，导致这款车型的销量严重受损。通用公司承认，到2011年11月底，Volt的销量仅为6,200辆，远不及10,000辆的全年目标。

    Volt shot out of the blocks early in the year with a blast of publicity that would rival Lady Gaga's. After snagging a flock of car-of-the-year awards, GM's bold technological leap seemed poised to set the world on fire. Unfortunately, its batteries did just that in certain accident conditions. The negative fallout -- combined with a month-long production halt in the middle of the year to boost output -- kept a damper on sales. After moving only about 6,200 for the first 11 months of 2011, GM admitted it would fall far short of its goal of selling 10,000 Volts in its first year.
