????2013年的圣誕節(jié)如期而至。對(duì)美國(guó)汽車工業(yè)來(lái)說(shuō),，年底猛增的銷量為格外成功的2013年畫上了句號(hào),。分析師預(yù)計(jì)，12月銷量的季節(jié)變動(dòng)調(diào)整年率可能達(dá)到1700萬(wàn)輛,，這也是近六年來(lái)首個(gè)達(dá)到這一銷量的月份,。同時(shí)，它將使2013年全年銷量達(dá)到1570萬(wàn)輛的高位,。

????盡管銷量大幅增長(zhǎng)讓人歡欣雀躍,，但它并不是汽車業(yè)今年最重大的新聞。底特律先是因?yàn)橥ㄓ闷嚬荆℅eneral Motors）提拔瑪麗?芭拉出任汽車業(yè)首位女性首席執(zhí)行官而歡欣鼓舞,；緊接著，福特汽車（Ford）首席執(zhí)行官艾倫?穆拉利在重回波音公司還是加入微軟公司（Microsoft）兩者間猶豫不決之際,，它又緊張得大氣都不敢喘,。傳統(tǒng)的三巨頭抱怨現(xiàn)有產(chǎn)能已挖掘到極限，開始制訂擴(kuò)張和聘用新人的計(jì)劃,。特斯拉公司（Tesla）讓電動(dòng)汽車的銷量火了一把,，而且不肯按行規(guī)出牌；而同時(shí)谷歌公司（Google）則在自動(dòng)汽車研制上一馬當(dāng)先,。

????當(dāng)然,，也有一些不那么樂觀的消息。隨著油價(jià)趨穩(wěn)并隨后下跌后,，電動(dòng)汽車的銷量馬上就開始受到拖累,。鈴木汽車（Suzuki）在美國(guó)市場(chǎng)上日漸式微，同時(shí)沃爾沃（Volvo）看起來(lái)也還是無(wú)力回天,。中國(guó)——現(xiàn)在已是全球最大的汽車市場(chǎng)——的銷售開始放緩,，而歐洲依然在衰退中泥足深陷，汽車業(yè)產(chǎn)能過(guò)剩的根本性問題還是無(wú)法解決,。

????下面就是今年汽車業(yè)所經(jīng)歷的高峰和低谷：???

????Christmas arrived on schedule for the U.S. auto industry as a spurt of sales put the wrapping on a surprisingly successful year. Analysts predicted that sales in December could hit a seasonally-adjusted rate of 17 million, which would be the first month at that rate in nearly six years. That would push 2013 sales up to a robust 15.7 million units.

????Welcome as they were, surging sales weren't the biggest news of the year. Detroit celebrated when General Motors (GM, Fortune 500) made Mary Barra the auto industry's first female CEO, then held its breath while Ford (F, Fortune 500) CEO Alan Mulally dithered over a move to Seattle and Microsoft. The old Big Three, complaining about straining available production capacity, made plans to expand and hire. Tesla(TSLA) fired up electric car sales and refused to play by industry's rules, while Google(GOOG, Fortune 500) pioneered a car that drives itself.

????There were reversals too. Sales of electric vehicles suffered as gas prices leveled off and then fell. Suzuki wound down its presence in the U.S. market, and Volvo looked none too healthy. Sales in China -- now the world's largest auto market -- slowed, and Europe remained deep in a slump, its fundamental overcapacity problems unsolved.

????Here are some of the year's pinnacles and potholes:????
