The shorter gearing really makes the car more fun to drive and increased my gas mileage because you could get into lean burn at lower speeds. I think on my black car in the sig I could get into lean burn at 52mph and it would stay in lean burn down to 47mph. It also had a replacement flywheel that was not oem so it was heavier, I could hear the idle air control valve constantly fluttering at idle to keep the car at its idle speed from the extra weight

The y5 had dished pistons and lower compression. The new higher compression car probably isn't as effecient as the lower comp one in lean burn because it's adding more fuel to less air volume. Probably runs alot better though, but no advantage to gas mileage.

To update my trolling in page 2 my red car has been getting 42mpg city after fixing a major oil pan leak and replacing the factory pcv valve
