It doesn't get much attention as a green vehicle, but the 2014 Chevrolet Silverado pickup truck line is the best-selling vehicle line at General Motors.

Now there's a zero-emission version, and it's available today.

That means that you can acquire one even before this spring's launch of the all-new models with more efficient V-6 and V-8 gasoline engines.

There's a slight catch, of course.

As you might expect, this one is considerably lighter--and dimensionally more compact--than the versions fitted with gasoline engines.

Surprisingly, its design is flatter and blockier than the carefully smoothed lines of the new gasoline trucks coming in a few months.

And it carries considerably less cargo than the less fuel-efficient gasoline models, whose heaviest versions are likely to come with load ratings exceeding 10,000 pounds.

(Load capacity is a huge mark of macho status in the full-size pickup truck world--even though you compare rated capacities among makers at your peril.)

You might think that a zero-emission Silverado pickup truck would take a similar approach to VIA Motors, which fits a battery pack and electric motor in converted GM pickups to permit all-electric running.

But in fact the emissions-free 2014 Silverado--which, today, is offered exclusively online by a special GM division--has no batteries or electric motors.

Rather than describe the technological details, we defer to the maker for its full description.
