Motor week did a test on the Aveo and the Yaris and a couple of others.
(Both were stick shifts)
The Aveo got 26MPG on their test loop and the Yaris got 39 MPG on the same test loop. 50% difference!
I have heard them say they try and run all cars on the test loop at the same speed and driving style.
I really like the way the aveo looks and how it sits inside but 26mpg?
My Crown Vic will average 22 if you drive it easy and it is heavy with good power.
I know that the Yaris and the Aveo are about the same weight, frontal area, displacement and horse power.
I also bet the gearing is very close. So why does it use 50% more fuel to run down the road than the Yaris?
I am stumped. I would buy one tomorrow if the mileage was good.
