I have a little over 48,000 miles on my Hybrid. I have driven it in many different driving conditions from the cold in western NY to the heat of the Southeast and it has performed great. I have gotten just over 45.0 mpg. I have tracked every mile and every gallon. Over my 2007 Civic LX it is a 26.1% improvement in gas mileage. I do mostly highway driving and would recommend this car to anyone.
The XM radio has been great especially over the long drives. The navigation system has been a real help especially when in cities that are new. The accuracy is great.
This is my third Honda Civic in the past three years. Each have been very reliable. it does the speed limit with ease, gets great gas mileage, what else could you ask for.
