Do you know what kind of ratio gears are in the rear? If you're cruising on the highway mostly, 2.73s or even 2.55s will do nicely with a 4 speed auto.

I had skirts on my Marq, but that was before I was worrying about gas mileage and they got ripped off after an accidental off-road adventure.
I think they're 2.73s, Going by Automobile-Catalog.com.

I once had a grille block on this car but didn't check the economy while it was on since it wasn't driven much. The one tank I have logged in the Garage as of this post time is the first tank-to-tank measurement I ever got in this car, Before that we just did partial fill-ups.

I'm interested in the rear skirts and a belly pan. I'm also open to a Diesel with Manual Transmission conversion, But would like to do some other mods first and maybe get new tires; These things are probably 22 years old. (It sat in my grandmother's garage for a long time before we got it.)

Also, Here's a thought; Converting it into a hatchback for aerodynamic and storage purposes. Can I replace the rear seats with middle seats from a station wagon so they can be lowered for even more storage, Too? It's a thought, At least. I have the thought of adding a trailer hitch too, But I don't know what I'd tow with it.

And again, Would removing the pollutant controls from the car increase the economy? The car is already stinky upon start-up compared to newer cars, But I'm curious.

Also, I imagine I can add an air-bag system. And this car doesn't have cruise control as-is, I think that can be added too.

What is an induction system...?
