The big announcements at this year's Detroit auto show, now open to the public, were pickup trucks, one from each of the three U.S. automakers.

The 2019 Chevrolet Silverado and 2019 Ram 1500 full-size pickups made their debut, each its company's highest-volume single nameplate.

So did the 2019 Ford Ranger, a mid-size pickup to compete with the Chevy Colorado, Nissan Frontier, and Toyota Tacoma.

While electrification is creeping slowly into those trucks in the form of mild-hybrid and enhanced start-stop systems, only one maker has offered full hybrid pickups along with their full-size SUV counterparts.

That would be GM, which offered the complex and very costly Two-Mode hybrid system in two pickups and three SUVs from 2009 through 2014.

That system was not renewed in the generation of trucks now being replaced, and none of the Detroit Three have offered plug-in hybrid or battery-electric pickups to the public.

Our previous poll asked Twitter followers what powertrains they thought should be used to make big pickups greener.

This week's poll asks a different question: What percentage of big trucks will have some form of plug-in electric powertrain by 2025?

Numerous small companies have announced plug-in pickup trucks of various types, but thus far, no large global maker has done so.

The battery-electric Bollinger B1 mid-size utility vehicle offers a removable rear roof to create an open bed, and Via Motors has promised to expand sales of its plug-in hybrid pickups and vans.

But we wanted to get a sense of how fast our Twitter followers thought plug-in technology would spread into the big-pickup world, which now totals roughly 2 million vehicles per year out of a U.S. market of about 17.5 million new vehicles sold last year.

Given that 2025 is likely to see a new generation of Chevy and Ram pickups, and a newer generation of Ford F-Series pickups will come before that, it's not unreasonable to think a plug-in option might be offered by one or more of the Detroit makers.

But to keep all options open, we've split the four poll choices into percent ranges: 0 to 5 percent, 5 to 10 percent, 10 to 20 percent, and more than 20 percent—and, again, remember this is by 2025, or only six model years away.

As always, please note that our Twitter polls are far from scientifically valid, due to small sample size and self-selection by those who choose to participate.
