I found a real tall final ratio for my 2000 Metro, 3.28 vs 4.39. The difference in engine speed is 500 RPM at 55mph. The mpg is up 10% but is hard to drive above 55mph and maintain mpg. This ratio will allow me to realize real gains from planned weight reductions and aero-mods. This ratio is referenced on a 94 swift in Europe. I cannot find any other reference to it but am lucky that I found it.
