I used to average about 53mpg in my 94 Metro 5 door (they count the rear hatch) with the 5 speed stick 1 liter 3 cylinder is the trick and breaking it in easy helps too. I didn't even get into extreme tire pressure until I got my xB so it could have gotten even more mileage.
A great deal of the XFI's fuel economy came from the grind on its cam. From what I understand, you can drop an XFI cam into a similar-vintage Metro and get a good portion of the gains.
If you can't find an XFI cam (could be hard to find), you could find a spare Metro cam and have it reground. I can't find the link, but I think there's a shop in Tacoma, WA that will regrind it to the XFI specs pretty cheap.
I have an opportunity to purchase a 1997 Metro 4 door 5 speed, 4 cylinder, for $1000. Is it possible to get good FE out of it?
It has working a/c, and 2nd gear wants to pop out unless you shift a certain way. Maybe replacing the trans fluid can help it. I don't mind replacing the transmission. While I'm in there I could throw in a good clutch and a light flyhweel, if I can find one.
I had one of those for a while. didn't keep up with mileage back then.
one thing to remember is the 4 cyl is still only a 1.3 liter. as far as todays cars go, very small indeed. I think it was also rated around 85ish hp. it was a little peppier than the 3 cyl (had one of those too) at only around 55ish hp.
both did really well on gas though at the time gas was only $1-$1.50 a gallon so nobody really gave a rats ...... well you get the idea.
Be the change you wish to see in the world
