2009 Toyota Prius 4dr Hatchback (1.5L 4cyl gas/electric hybrid CVT)
I am averaging about 29 mpg in city driving. Admittedly my trips tend to be quite short, but I am by no means driving with a heavy foot. I often coast for blocks when I anticipate a light changing ahead, accelerate slowly, but it seems to make little difference. The car has been tested 3 times so far and the dealerships say it is fine. Since the only reason for leasing this car as opposed to less expensive vehicles was for mileage, I am very disappointed. While the car is quite comfortable and the interior functional, the stereo is of very poor quality. And, contrary to an assertion made, adding a subwoofer improves, but does definitely NOT transform the sound.
Can't think of any.
Better mileage or better ways to find problems and make adjustments regarding fuel economy issues. A real stereo, for heaven's sake!
