"My preference would be for it to be an internal candidate just because as you might expect, in any company in any industry, it's less disruptive," Akerson told Automotive News.
Akerson joined GM as a director shortly after the automaker's 2009 bankruptcy. Akerson ascended to the position of CEO following the firing of then CEO Fritz Henderson.
Akerson hasn't put a specific timeframe on how long he wishes to remain GM's leading man, but he has previously indicated it would be in two to five years.
"I owe the board, as every CEO does, what happens if I get run over today? What would I recommend you do, tomorrow," Akerson said. "But that's not what we're really worried about. We're worried about what happens two to five years from now."
