Hybrid cars have well and truly hit the mainstream.

After years of slow sales around a decade ago, Toyota has now sold over 4 million hybrids. And Honda recently passed its first million.

But in the home of the U.S. auto industry, buyers have been slower to catch on to the concept.

According to the Detroit Free Press, research by Edmunds shows Michigan consumers are buying hybrids at a rate well below the national average.

Hybrid cars made up 3.4 percent of the new vehicle market in August.

And Michigan consumers buy 3.7 percent of all vehicles sold in the U.S.--but they've bought only 1.8 percent of all the gasoline-electric hybrids sold. Michigan also accounts for only 1.5 percent of all plug-in sales.

It's good news for hybrids in general though. That 3.4 percent figure is a whole percent higher than over the same period last year--no doubt helped by strong sales from the Prius line.

And Detroit's own Chevy Volt is continuing to out-sell its Nissan Leaf rival, once again topping its previous sales record with 2,961 units shifted in October. The Volt has now sold almost 20,000 units in 2012.

But with a bit more help from its home state, that number could be even higher. How about it, Michigan?
