The splashy electric-vehicle unveilings at the Paris auto show may have left some onlookers puzzled -- and understandably so.
Chasing the Chevrolet Bolt, with its 238-mile range, several automakers say they will come to market with EVs featuring lower prices and better ranges than the first generation. It's fair to ask why, considering the low sales of EVs so far.
But the industry is feeling pressure from tighter limits on tailpipe emissions -- a trend spanning several major markets -- and the prospect of new competitors such as Tesla and Google. Automakers are wise to keep tuning up their batteries and cars.
