The report I saw also said to look for no savings at the pump long term. Despite the anitcipated increase in economy, user consumption and fuel prices would increase.

IMO, the rising cost of fuel sucks. The good side is that it is driving R&D to find alternative fuel sources and simultaneously lower emissions. My hope is that in the same swipe auto manufacturers don't kill the current Horsepower race they are in. Hopefully they will look to the use of Superchargers and continue the variable displacement research.
I have been somewhat watching the newest developments from Chevrolet. I was thinking of replacing our 03 Avalanche with an 07 Tahoe. Since all of these engine and economy changes are lingering in the air, I have decided to hold off and see what becomes of the powerplants in the near future. Chevy is already selling the E85 multifuel engines as well as a new hybrid coming out for 08. Exciting things are also happening in the diesel world with the announcement of Low Sulfur Diesel to come out in the next year or so. Look for a lot more cars, trucks and SUV's to be Diesel equipped when that happens.
