Metro XFi ('89-'94)
Metro Base Level ('89-'00)
Metro LSi ('89-'93)('95-'01)

All Geo Metros came standard with a 1.0 liter, 3 cylinder engine. The XFi model was designed for maximum fuel efficiency. It had a lighter curb weight, different computer, camshaft and transmission than the base or LSi models. It also had less comfort and convenience options than the other models. It boasted 53 city/58 highway mpg numbers and received "Most Fuel Efficient car in America" for all six years of it's production. It was dropped after the '94 model year because of slow sales.

I am not exactly sure how to check the engine for this, but the car should be clearly marked or badged as an XFi if it was. The EPA readings always vary and you cannot base your conclusion on that.

You could go by the curb weight if your tag is still on the door.
