I think in the near future (maybe within 10-15 years) things will start to head back to the way they were in the 80s... No doubt fuel prices will continue to raise, meaning more and more people running to the lots to trade in their big, high hp cars for some fuel sipping economizer. Auto makers will have to scale back production of high hp cars and make more economizers, making the prices of what few "cool" cars that will still be available go up into a price range that only the rich and famous will be able to afford.

As far as Camaro's go from looking at this CAFE chart, they're probably ok up until about 2018, but as the years go on looking at the year 2025, can you still see a mid 400 hp Camaro getting a 34 mpg window sticker?
Technology has come so far since the 80s, and thinking about it myself, what more could they possibly improve to achieve a 34 mpg window sticker, and manage to keep the high HP? Weight reduction? It can only go so far at the moment, while still maintaining safety standards that the auto manufacturers must follow. I imagine that will get worse in the future too, more air bags, bigger crash bars, etc = more weight to haul around....
I think now is a great time to be a car enthusiast, and to get them while you can, because while I don't think we are at the peak of performance/technology yet, but once we hit that peak and manufactures are starting to push the limits of the MPG standards they are to be held to as the years go on... It will all be down hill from there.
Just my prediction... Hopefully I'm wrong
