The electric car is almost here. Hybrids abound. Diesel has cleaned up its act. Even conventional internal combustion engines can be tweaked to do a bit less harm to the environment.
A brighter, cleaner future is a mantra at the auto shows this year. Scratch beneath the surface, however, and a different sort of impression emerges: Change may be coming to the automobile industry, but progress is slow — even grudging — and the message can be murky.
Chevy has been hyping the much-discussed Volt, for example. The manufacturer’s new electric car – due later this year – can go up to 40 miles on a single charge before a gasoline engine kicks in to keep passengers from becoming stranded.
