Hybrid sales have fallen along with gas prices, but you can count on gas prices rising again before too long. The Prius, all by itself, owns half the hybrid market so Toyota needs to be ready.

The redesigned 2010 Prius will manage combined city and highway fuel economy of about 50 miles per gallon, according to Toyota. That's four mpg better than the current Prius.

It will be powered by a larger 1.8-liter, 4-cylinder engine. Only about 10 percent of the current Prius' hybrid drive system has been carried over into the new vehicle, according to Toyota.

The new system is smaller and lighter, which contributes to fuel economy. Toyota also boasts that the Prius is the most aerodynamic mass-produced vehicle in the world.
