2013：全球車界這一年

????成功突破玻璃天花板

????瑪麗?芭拉從通用汽車的第三把交椅升至第一把交椅，獲得首席執行官提名，這一路上她突破了好幾個歷史性障礙。一方面，通過任命一位非執行主席掌管董事會，她能更容易打開工作局面；但另一方面，由于一位對手接手了她以前的職責，她現在的工作又變得更棘手了。她是二十年來首位掌管公司的產品工程師，各種建議勢必將紛至沓來，令人應接不暇。這些建議小到新皮卡上的空調出風口，大到別克（Buick）和雪佛蘭（Chevrolet）這些品牌的前景，無所不包。

????Busting through the glass ceiling

????In being named CEO, Mary Barra broke through several historical barriers in moving from GM's third-most powerful executive position to its first. Her job was made both easier by the appointment of a non-executive chairman to handle the board of directors, and more difficult by the decision to give her old job to one of her rivals. As the first product engineer to head the company in two decades, she will be deluged with suggestions about everything from air conditioning vents in new pickups to the future of brands like Buick and Chevrolet.
