My wife has a Prius and I have the Civic. The Civic's gas engine runs more than the Prius' so it's not as fuel efficient but still VERY good at 44 mpg 90% city driving. The Prius shuts off its gas engine whenever it has an opportunity but the Civic does it only when the car is stopped at "D" or at VERY light throttle. If the car is in "Park", the gas engine will keep running, unlike the Prius. It's much more fun-to-drive than the Prius thanks to its sportier ride and handling. It doesn't have as many gadgets to play with but it has all the essentials. If your only concern is fuel economy, buy a Prius. If you want more fun while saving gas, get a Civic Hybrid.. shorter wait, too! 6wks vs 8+ wks
Interior is top notch. Looks better than a Prius IMO. Automatic Climate Control. Excellent driving position.
The "idle stop" mode needs improvement: If I stop at a light on an incline and I don't apply enough pressure on the brake, the car will roll back! Change those UGLY rims! Ugliest rim ever on a production car IMO! Shut off engine when car is in "Park". IPod interface. Outside temp on a separate screen
