Still no actual highway MPG tests?????

My real world 55 mph mpgs in warm weather:

2011 Prius 2 = 62.1 - bone stock
1996 3 banger Geo Metro = 60.1 - 140 lb wt reduction, grill block, head light covers
1995 SOHC Neon = 46.0 - lighter rims, CAI, big TB, big cat, better muffler, no PS
2005 Dodge Neon SRT4 = 33 - 335 hp stage 2 w/S3 tubo - DOTS - pump gas
1984 Plymouth Horizon = 24 - stock 94 hp 2.5 from a 92 Shadow

It'd be great to add some horsepower numbers to the remaining vehicles, just for some more perspective. IIRC, your Metro was ~48 to 54 hp,

Curb weights would be great too, but you might not know after those mods.
