Just watched this the other night and thought it was worth posting. Its a kind of interesting design that differs from others I've seen. Not the most efficient at lower speed, but not bad overall. The Accord Hybrid is rated for 49 city and 47 highway. Not bad at all considering how large the car is. I've seen one of these in person and its a very nice looking vehicle for those of you looking for something larger than a Civic or Prius.
As a side note, this guy has some really great youtube videos explaining car operation in general (I don't bother with his car reviews). I've watched a bunch of his stuff and can definitely recommend it.
