General Motors isn't changing anything in the long term because of lower gas prices.
"It's solving broader problems than just the cost of fuel: environmental congestion, et cetera, across the globe," she said in a "Squawk Box" interview.
Speaking on competition from Tesla Motors, Barra said making electric cars is a "pathway we were on." GM has been developing clean fuel vehicles for years, starting with the Volt in the early 2000s, she said.
Barra added that GM is working on a new model of the Volt to extend its electric driving range beyond 50 miles before the car switches over to gas. GM also is working on the Bolt concept car, which has an even greater electric range of 200 miles and should cost as little as $30,000.
Barra said GM sees strong opportunities for growth in the U.S. and China. Europe, however, is a "fragile" market, she said, noting that the Opal brand is one vehicle that would benefit from a stronger economic recovery in the region.
Speaking on GM's recent slew of recalls, Barra said the company would "completely support" any additional callbacks. The number of recalls had fallen in the last six months because of what she called GM's proactive, data-driven steps.
"Obviously I want to get to a place where we have the safest vehicles and we aren't doing recalls given changes we've made to our development process," Barra said. "But as we see issues we're going to take care of them."
