NEW YORK: General Motors announced plans Monday to launch 20 all-electric cars by 2023, part of a long-term push to an "all-electric" fleet as governments globally embrace fuel efficiency.

The biggest US automaker said it will introduce within 18 months two new models built on the learnings of the all-electric Chevrolet Bolt, which was launched in December 2016.

"General Motors believes in an all-electric future," said General Motors executive vice president Mark Reuss.

"Although that future won´t happen overnight, GM is committed to driving increased usage and acceptance of electric vehicles through no-compromise solutions that meet our customers´ needs."

The Bolt, the first all-electric vehicle aimed at the middle market, now faces competition from Tesla´s Model 3, which has won admiration among many environmentalists and car aficionados as a leader in new car technologies.

Car companies are investing heavily in all-electric vehicles as officials from China to Europe emphasize the need for more energy-efficient vehicles, even as today´s fleet remains overwhelmingly populated with conventional autos.

Officials from Britain and France are among those who have said they plan to block sales of diesel or gasoline-fueled cars in 2040, while Norway has set a 2025 deadline.

China has set a target that at least 12 percent of cars must be hybrid or electric by 2020.

GM got a boost Monday from Deutsche Bank, which upgraded the company´s stock to "buy" and said it enjoys an advantage over competitors in "autonomous and new mobility models."

GM shares jumped 4.5 percent to $42.19 in afternoon trading.
