This made me lol, MHz does not represent how many calculations it's doing. The difference is more like x 4 times the cores x 2 times the instructions per clock, not counting the more advanced instructions that the i7 has. But anyways...

I agree, back then the cars that got better fuel economy did so because they sucked.

hatman, there are better ways of attacking part load efficiency than warm air intake, which is very crude. Many new engines are coming with cooled EGR, for example. Most mods ecomodders do are probably considered unacceptable for more reasons than just "people won't like them". Longer gears that require downshifting piss people off already.
