Porsche and Audi challenge Tesla in electric car market

The high-performance electric car market is shaping up to be a high-profile battleground featuring some of the world’s most glamorous brands after Porsche and Audi unveiled models to challenge pioneer Tesla Motors.

Consumers have largely shunned electric vehicles because of their high price tags and limited driving range, as well as the scarcity of charging stations, though many analysts predict sales will rise sharply by the end of the decade.

Tesla, however, has enjoyed success and managed to stay ahead of the pack with new technology, which has extended driving range and reduced costs.
