The stock price of General Motors reached a 52-week high in late morning trade, jumping 3 percent to $30.28.
Akerson also said GM sales in North America should outpace the rest of the market this year. Last year, GM's U.S. sales rose 3.7 percent, slower than the 13 percent industry-wide increase.
GM predicts that total industry sales in the U.S. will increase from 14.5 million last year to between 15 million and 15.5 million this year.
Akerson also forecast small growth in his company's U.S. market share in 2013, largely fueled by new vehicles such as the Cadillac ATS small sports sedan.
Akerson, 64, said he expects to be GM CEO at this time next year. Beyond that he says he doesn't know. GM's board, he said, does periodic talent reviews as part of its succession plans, adding that there is a "stable of very capable leaders" to succeed him at the company.
He said that GM is in discussions with the United Auto Workers union about lump-sum pension buyouts, but he wouldn't comment further.
The company offered buyouts to white collar workers and switched its salaried pension plan to an insurance company annuity last year. GM's pension plans have far less money than needed to meet their obligations.
