This article reminded me that the CEO is not always the president. Mary Barra is still the Chairwoman and CEO.
But Mark Reuss is awesome as far as I have seen. His resume is great and he clearly rose on the technical/engineering side, rather than the business side. I always appreciate that.
With a background in engineering, Reuss has spent his entire career at GM. He joined the team as a student intern in 1983, eventually working his way up to chief engineer of GM's large luxury vehicles and leader for GM's racing vehicles, among other roles. For a brief period, he was GM's vice president of global engineering. From 2009 to 2013, he served as president of GM's North American division. Reuss' father also served as GM president from 1990-1992, according to Automotive News.
