While GM has withdrawn most of its previously announced electric vehicle targets, the automaker believes its EV sales momentum is finally building thanks to an expanding lineup of all-electric vehicles — spanning a price range of roughly $35,000 to more than $300,000.

"We are definitely outstripping the industry in terms of growth, in terms of EVs," Rory Harvey, GM president of global markets, including North America, told CNBC last month. "We have the most comprehensive EV lineup out of any manufacturer in the industry, in the U.S., at the moment."
