I had a mid-90s Geo Metro 4-door Hatchback for a couple of years. I loved it. I got it used, when it was a few years old. The prior owner had put platinum spark plugs in it, an upgrade from whatever was stock when it was manufactured. No matter how I drove it, no matter how heavily I loaded it, it got 55 mpg. But if I turned on the AC, the mpgs would plummet to 49!
I'm a big guy, but still found it roomy. In fact, I once moved a 6-foot-long table inside of it. Unfortunately, driving in an unfamiliar place where a shadow obscured a median with a tall curb, I ran it aground, badly damaging all kinds of things on the underside of it. Despite not looking very damaged from about 6 inches up, it was unrepairable and a total loss.
I've gotten some decent mpgs out of some 4-bangers: a Saturn SL1 sedan I could squeeze 40 out of at times and the Scion XA we got about 13 years ago, which I once got 44mpg out of, and which we traded in on a 2015 Mirage DE...YESTERDAY!
We're still using the gas that the used car dealer put in the Mirage. When we're ready for a fill-up we'll do a proper miles per gallon test. When I look under the hood, at that tiny engine idling, I get a happy feeling.

My 2nd car was a 91 Periwinkle Blue with Pink side stripes 5mt Pontiac Firefly. Could do 70mpg if I tried. That car went through some electrical issues though and caught fire one day (2000w system, 4 15" RF subs). Blew out 4 rear windows.
Later on I got my start in Auto X and Amateur Rally with the coveted Firefly turbo. At the end of that cars life, it had a 2" lift, 12psi turbo making 220hp, full roll cage, and had been gutted with lexan windows, no interior, and weighed in at 1450lb. Top speed was 250km/h with a built racing trans (gearing limited) and did 0-60 in 4.9 seconds.
All photos hosted on an old, no longer serviced photo host. I wrecked it at a track day trying to qualify for the next racing class at Mission Raceway. Blew a front tire and took a wall pretty hard. Roll cage worked!
Now own a Mirage, and a Micra.

^ Wow, on so many points.
Holy grail! I saw a turbo in Vancouver about 5 years ago. Looked like it was being daily driven.coveted Firefly turbo
It was good for about about a 2% gain @ 88.5 km/h / 55 mph
I suspect the Mirage would gain less with a similar mod, since the back of the car is better optimized compared to the Metro/Firefly, what with its drag-reducing rear spoiler and tapered roofline.
Darin coming across your hypermiling experimentation is part of what got me into Metros!
While I may have bought a Mirage I don't yet technically own one. It's sitting in Ohio waiting for me.
43 days until the Red Metro is retired(frame horn in done for, driving with frame brace)
Then I'll retrieve get my black one with possible intent to get collectors plates(Hasn't moved from the barn it's in for a year and a half, first car, little rust, & under 100K miles)
Then in 53 days I'll take delivery and be an actual Mirage driver. If I can't easily average over 50 mpg I just know I'm going to be dissapointed. Hope it will be eco friendly enough to my liking.
