We’re not kidding. The next iteration of America’s favorite Hybrid has been unleashed on the unsuspecting internet via a commercial on YouTube. The decidedly more svelte 2010 Prius is set to a jazzy rendition of “My Favorite Things” from The Sound of Music. There aren’t a whole lot of details out for the car just yet, but the video gives you a good look at the car’s new interior and exterior. We’ve got to say it’s an improvement over the previous model.
