It's a hybrid, which is nice. Toyota's "Hybrid Synergy Drive" really is the bomb. It's not just marketing hype. ;-) More important (to me), the car looks totally sci-fi! This is what an automobile in the 21st Century should be like! (flying cars notwithstanding)
If you haven't ridden in one, two things (aside from the plethora of electronic bells & whistles) will stand out the first time you do:
1) For a small-ish car it's surprisingly roomy. Despite the fact that it has both gasoline and electric drive systems, the cabin takes up a surprisingly large portion of the total volume of the vehicle. It's almost TARDIS-like.
2) It's quiet! The gasoline engine only runs when it has to, so at low speeds the only sound is the wheels on the road. People in Prius discussion boards refer to it as "stealth mode". In fact, this morning on the way to work I couldn't help but use it for a bit of mischief. I was in the parking garage hunting for a spot when I spotted someone walking while talking on his cell phone. No joke- I was able to sneak up on him and follow him for a short while without him noticing that there was a car right behind him! Evil fun! :-)
Another fun thing is the smart key system. With the key in my pocket, I can walk up to the (locked) car, get in, start it up (by pressing the power button!), and drive over inattentive pedestrians without ever touching the key. Nifty!
I could gush on and on about this marvelous piece of technology, but I'll spare you all. You get the idea. The best part, of course, is that now I get to be one of "the cool kids", along with serolynne and slartibart. ;-)
(This isn't my actual car, but it is the same model, color, and option package. I'll post pix eventually.)
