The car is suppose to be most efficient in the city. However, the hybrid doesn't perform any better than a non-hybrid civic. It averages 34-35 mpg when it is rated at 48/47 mpg. A very annoying feature is the air conditioning. Living in the south, we really need a strong air conditioner, however, the hybrid shuts down when you are stopped. This is to save gas, but the air conditioner also shuts down and temperatures in the car can be unbearable if you are stopped for long! For the price that I paid for the car, I could have purchased a much more luxurious vehicle with more bells and whistles and just slightly lower gas mileage. Hold out for a Prius!
