The Next-Gen 2010 Prius debuted today in Detroit with 50 mpg, based on Toyota's own internal testing. With a 1.8-liter Atkinson-cycle, four-cylinder engine.
In http://www.autobloggreen.com: The new Prius has three driving modes: Eco, EV-Drive and Power. The EV Drive isn't anything new – if you have a Japanese Prius. A first for the U.S., the Eco mode allows battery-only operation "at low speeds for about a mile, if conditions permit." This is still the nickel-metal battery pack, after all. The other modes should be fairly obvious, with Eco providing the best mileage and the Power giving the car a "sportier feel."
The optional Solar Panel roof will generate power for circulating air and keeping the interior temperature from going too high. There's even a remote-controlled A/C system that can run on battery alone and lets you set the temperature before you get in.
