The trannies have a lot to do with it, since RPMs kill gas mileage. But Chrysler has develope the variable valve system. Where when you are just cruising your basically only running on 4 cylinders. When you need more power then the motor will come to it full potential. I think they use that technology in the new 300C's. Pretty cool.

I think this was tried in the past also. I can't remember who tried it, but it was very unreliable. I guess we will see how it performs once its been out for a few years.
