EC IA | I have a friend with an '05, says he likes it, his only complaint is that due to emissions the hp is actually less than what it was in '04.
The reason for the loss of mileage in the '06 is probably due to the new emissions requirements. Not to mention the increase in Hp, it takes fuel and air to make Hp, and with the same size engine but that much more power, something has to be consumed. | |
