Bigger engines like a Mustang's usually turn low (<1800) rpms @ 60 mph.
I'm leaning towards the same. I could get decent mpgs with my Corvette (which is probably the best mpgs for a V8 car due to light weight, excellent aero, and super high OD) but there was no way I could accelerate, even lightly, at 25mpg+. High revs at 60mph indicate a smaller engine.

I'd guess a TDI Golf with a manual tranny. I'd definately say manual since the rpm and engine speed is proportional, but I would have figured the coasting would be EOC. Whatever it is, it coasts a lot longer than anything I drive.
