A little different angle here. We have had VW tdi's (diesel) for years. Our current 2006 jetta tdi automatic averages 42mpg has great acceleration and huge trunk(this model is prior to dieselgate) and still has a sporty look unlike a prius. We get 600 miles per tank on the highway running 73mph. We even pull our 5x8 trailer hauling 2 scooters and get 34mpg. Yes diesel cost more but for a economy car / commuter for my wife it has served us very well. Over 300k miles on it and still her daily driver. Ive considered the Prius and still will when the Jetta gets replaced. We also own a Lexus RX450h (hybrid) and average 26-30mpg. So our 06 E is out performed with economy, but the grin factor is huge! I love my E!
