[me and my metro]

Gear ratio is a big factor in a Metro. There are four different ratios available. They range from 4.4 to 3.5 in 9% jumps. Obviously the big car with the small engine gets the 4.4 from the factory. As you slow the engine down you can advance the cam to gain low end torque. My high point was 54 mpg in a 95 sedan with a 1.0 and 3.8 gears. It had an Xfi clone cam and a +10 cam gear. Zero aero mods other than a grill block. The fun car got 44 mpg and was a 91 coupe with a 1.3 with 3.5 final.
