I have to say, I am a visual person and I have done much better on the freeway with the Q45 (4.5L v8) than I did with the 97 Toyota Avalon (3.0L V6). I credit that with the video style mpg display that is part of the car. There is a instant bar graph and a continuous digital dispaly in the same screen. On longtrips, if I'm at 24.8 avg mpg, for example, I'll start trying to get it to 25mpg. In thew Avalon, there was no mpg gauge and i never got better than 26mpg on the road. I have gotten 27mpg on the bigger infiniti. And I probably NEVER would have gotten that without the constant feedback while driving.
