财富的尴尬

    全世界的汽车厂商都明白，能否攫取更大的市场份额、甚至仅仅只是保住目前的市场份额，在很大程度上取决于车型更新换代的速度，而且他们确实动真格了。

    美银美林（Bank of America Merrill Lynch）分析师约翰•墨菲每年一度的研究报告《汽车战》（Car Wars）吸引了大量读者。墨菲指出，1991年到2011年间，汽车行业平均每年会对16%的车型进行更新换代。但到了2012车型年（从2011年10月1日开始），汽车业的换代率却跃升到了23%，2013车型年还会达到惊人的32%。

    过去20年里，美国消费者每年可选择的新车平均有38款，但从今年开始，在接下来四年里，他们可选择的新车达到了平均每年46款。

    当然，这些新车型各有千秋，各大厂商的行动速度也有快有慢。以下我们谨对各大厂商的行动做一个简单的分析，并列出他们最热的几款车型。

An embarrassment of riches

    Manufacturers around the world have learned that gaining -- or even holding -- market share is largely dependent on how often they turn over their fleets, and they have taken the lesson to heart.

    According to John Murphy of Bank of America Merrill Lynch, author of the widely followed annual "Car Wars" study, the industry replaced 16% of its fleets annually between 1991-2011. But the replacement rate jumps to 23% for the 2012 model year, which began Oct. 1, and then surges to an extraordinary 32% for the following year.

    While customers got to choose among an average of 38 new models every year for the past two decades, they will see some 46 new offerings coming their way every year for the next four.

    All new models aren't created equal, of course, and some automakers are moving faster than others. Herewith, an analysis of the activity by each automaker with a guide to its hottest models.
