I am new to the Cleanmpg club. We just moved from 7100' elevation in northern NM to 1500' Phoenix Arizona. Our all wheel drive 2012 Subaru Impreza is not the best car for high FE. We are trying to drive smart while we look at making a smarter decision on a future car. My other vehicles include a 2002 Tundra 4x4 with lousy mpg, a 99 Miata autox car, and 2 old Suzuki motorcycles that are my daily commuters. We really like the new Prius and 40mpg and higher economy cars. Phoenix traffic is not a great place to hyper mile, but we are trying hard. Brand new Prius V is scary expensive, so we are looking at older, used options. Thanks to everyone for the great info. This is an excellent source.
