... if you are getting a mid20s to high20s in a Crossover SUV. Why are you complaining?
My wife has a 2012 Edge V6 model. Her old 2010 Chevy Equinox AWD with 2.5L 4 cylinder engine only got about 28mpg on highway and 20~22mpg in the city.
My other car 2003 VW Passat W8 gets mere 20mpg on the highway.
The 3.5L V6 puts out more power than my 4.0L W8 and eats less fuel, while moving a bigger/heavier body. I'm Impressed.
I understand if you're upset because you're not getting the advertised MPG.. do you have a AWD model? that would decrease the MPG.
