I'm gonna guess, with that old G10 (that in at least one video, looks like it's pretty clapped out) and 3-speed automatic, they're probably getting somewhere in the 55-65 mpg ballpark highway, and probably in the 45-55 mpg ballpark city. If it were a manual, I could see 55-65 city, 65-80 highway.

They're not that much lighter than a Metro (IIRC, 1200 vs. 1600 lbs), so city will be a little better, but not that much better, and their aerodynamics probably aren't that much better. And, window sticker on a 1.0 automatic Metro was 36/39. (The manual was much better, at 46/49 for the regular model, 53/58 for the XFi.) And, I doubt they're hypermiling it.
