The event follows Barra earlier this year announcing a vision of an autonomous, zero-emissions future for the automaker. Last month, GM said it would launch a mix of at least 20 new all-electric and hydrogen fuel cell vehicles globally by 2023, including two in the next 18 months.
"We are committed to an all-electric future," Barra said during the third-quarter conference call, adding GM is "confident" it can make the vehicles profitable.
GM shares have surged about 30 percent this year to record highs since the company began trading shares at $33 a share in November 2010. In New York Stock Exchange trading Friday, GM shares rose up 1.5 percent to $42.76 as of 3:03 p.m. ET.
