The only reason I purchsed the 400h was because of the so called "great gas mileage." A joke at best. I live in Texas, it can't get any flatter, I am a very conservative driver and my MPG is at 21.2. I guess the only way to get the 29-33 mpg they claim is to drive under 40 mph, never run the air conditioner and live where the air temperature is always in the 70s.
I don't have a favorite feature. This car has been a big disappointment.
Tell the truth about MPG and fix the back seat middle console so that it doesn't squeak the entire time you are driving!
