I am still toying between the 4 and 6 in the Rav4 Sport 2wd. I have the 4 on order. I am hoping current owners of the 06 models in both 4 and 6 can post their actual economy and % of highway and city driving. When I use the Rav I will be driving 80% highway on my 12 mile commute. My wife on the other hand will be driving 80% city. She will be using the Rav more than I. Is the 6 as efficient as the EPA says in real world conditions? Thanks for all your posts!
