Lyon’s last post was head of interior design at Buick and GMC, and at Opel he was set to replace former design boss Mark Adams who recently moved to Detroit to head up design at Buick and Cadillac.
General Motors is yet to formally announce the latest executive shakeup though a spokesman for the company has confirmed that Lyon has resigned and that Adams will continue to oversee design operations at Opel until a new replacement can be found.
It’s unclear why Lyon, who has worked at GM since 1990, suddenly resigned, though there are suggestions he may have been asked to leave. AutoWeek, citing inside sources, said Lyon had been dismissed.
Note, Lyon’s resignation wasn’t the only high-level executive shuffle taking place at GM this week. The company also announced that its marketing chief Joel Ewanick would be leaving the company, again without offering a reason. There are suggestions in the media that Ewanick’s ousting is due to mishandling of recent sponsorship deals with English soccer clubs.
