my 06 mustang gt gets 24 highway already- and thats including half a dozen scorched onramps
I hear 26 is about the norm, one guy said he added a shaker and with no other mods than 'true' cold air got 30mpg- not too shabby from a mid 13 second pig of a car...I had it sitting next to the 65 galaxie- the new mustang is as tall/wide as that boat- but a couple feet shorter in length.
had my 69 sitting outside a while back, the new one dwarfs it. Window sticker said 'subcompact'...guess they myst rate them by gastank size/rear seat room or something like that- sure as heck aint by weight/height/width!
the highway mpg is all gearing with enough torque to pull it along- shifting from fourth to fifth, feels more like '4th to 10th' as the rpm drops so far. I think any engine with a mild cam profile building fair bottom end torque should have a steep overdrive- cant gear a low torque 4cyl that low, but with a decent torque gearing down sure helps...
I personally wish they offered a same displacement but 'severely undersquare' version of the modular, even with severely limited redline(even 4k?), I think an extra 100 ft/lb down low via extra stroke would 'feel' more powerful in everyday driving, and yet allow an even steeper overdrive for further mpg improvement. Kinda like a strong diesel- gobs of torque, limited rpm just requires wider ratio (or just more) gears. Heck some diesels sit you in the seat pretty good without ever hitting 4k...why not a long stroke/small bore gas?(also requires taller decks/longer rods to keep friction down)
