I picked up my '06 yesterday. On the drive home from the dealership, my trip computer moved from 37 mpg to 49 mpg around the 63 miles mark.

I will be curious to see how the mileage calculates when I do it manually after my first fill up. With my '05 HCH 5 spd, I got 50 mpg on my first tank, and averaged 47.5 mpg during the time I owned the vehicle. Although my driving style will be the same, first indications are that I may only get around 40 mpg in the '06. This is a bit worrisome, but I will have to wait and see.
