2．寶馬

??? 雖然聲勢可能不如去年那么浩大，但今年寶馬的銷量仍然穩步增長，而且寶馬依然穩居最環保的汽車廠商陣營。最值得關注的是寶馬最近推出的i系列轎車，這個系列將包含電動、混合動力以及其它替代能源汽車。不過最新的寶馬i3全電動城市轎車于2013年發布之前，寶馬仍將繼續推進更傳統的“高效動力”技術，以提高其汽油動力車型（比如最新的寶馬3系）的燃油經濟性。

2. BMW

??? It may not have made as much noise in 2011 but BMW enjoyed another solid year of sales increases and continued to position itself as the greenest of automakers. Most noteworthy was its rollout its i brand, which will comprise electric vehicles, hybrids, and other alternative-fuel vehicles. Until the launch of the all-electric i3 city car in 2013, BMW will continue to promote its more-conventional "efficient dynamics" efforts to boost fuel economy in gasoline-powered cars like the latest version of the 3 Series.
