GM hybrid SUVs get 21 mpg city/22 mpg highway

So you go ahead and get a big complicated Hybrid Tahoe to save you 2MPG highway? Sure city its a pretty good improvement at +7MPG.... But boy the hybrid model better not cost too much more over the standard because other than greenie wannabe's that truly don't understand what they're buying it'll be a loooong time before you actually save anything over for buying the hybrid model. Ohh and don't forget that many hybrids are having trouble meeting their EPA numbers....
