Toyota is amping up its product line in 2011, and we mean that in a purely literal sense. As you may have noticed, hybrid technology is catching on. There was a time when you could almost laugh the idea off. Not anymore. If your company doesn't offer at least one hybrid vehicle, you're more than a little behind the curve. So who's leading the charge? You guessed it: Toyota. And the world's biggest carmaker isn't about to let another automaker sweep the title from under its nose.

Toyota revealed not one, but two cars at the North American International Auto Show here in Detroit. The Prius v is a "big" Prius that you'll be able to buy late this summer, and the Prius c is a "small" Prius that is still in concept phase.
