I would like to see the high 40's or even into the 50's, but sadly we just don't have the technology to get us there yet with standard fuel. If you consider that the early Fords around 100 years ago were getting an average of 22mpg, then I don't think we have come all that far. Those cars were pretty heavy and had the aerodynamic properties of a brick, imagine where we would be for mileage if they had just a small portion of the tools and technology we have to achieve 30mpg. However I don't think it's just the technology holding us back, I think the fuel has changed considerably over that time as well. We might have to face the fact that there is an absolute limit to today's standard fuel no matter how you approach it or try to design around it.
