Just from checking fueleconomy.gov...I don't really get the point of the civic hybrid. The civic hybrid gets a little over 40 combined. The regular civic gets around 30 combined. Thats certainly an improvement...but the car costs a lot more initially and I have concerns about long term parts and maintenance costs. And the hybrid hardly gets astronomically better MPG. If I am a cheapass (and I am) it makes more sense for me to buy a sub compact, to me anyway.
Yes, I'm sure with careful driving you can squeeze more then those ratings out of the civic hybrid...but careful driving can squeeze a lot more out of the civic as well.
The insight is a little more interesting based on those numbers, now that starts to be an efficient people mover (gas wise). 50 combined is a more impressive number, especially if you're getting close to that in crappy city driving.
