IS-SV is probably correct here. That's how GM managed to get such good V8 MPG figures with their big, 5.7L V8-powered vehicles (Caprice, Roadmaster, Fleetweood, etc...). Even without a 6th gear, the top overdrive gear was WAY tall....down to the point where, at 60 MPH, the engine was lugging along at 1200 RPM or so, barely above idle. Of course, the V8's torque allowed this, at least to some extent. Ford could also do this with the Crown Vic/Grand Marquis, but not quite as much...the 4.6L had different torque characteristics than the 5.7L.

That's a oversimplification because fuel mixture is not a technology, but "other advanced technologies" impact and control the fuel mixture and these technologies are applicable to 4/6/8 configurations, including port injection, direct injection, 4 valve heads, variable valve timing in various forms of sophistication, DOHC, etc.
The point is cylinder count alone has minimal impact compared to displacement when all other technologies are the same.

Ford's press release states the 19/31 rating is EPA certified.

He's just trying to point out these were not preliminary EPA numbers. Often car manufacturers publish preliminary EPA estimates and they footnote them as such (which usually aren't that far off from the final numbers).

True the Mustang here and those cars are probably not used for highway cruises at 60 MPH but it still a great feat (the Vette does a good job as well on the highway with a lot of power).
Its clear to me that people and companies as a whole don't care about improving MPG. Only a few have done it and made significant steps doing so.
Now that they have to have 35MPG in a few years on avg (with loopholes) I hope to see more innovation in regards to MPG.

I still feel the current EPA mileage estimates are useful for making comparisions between various cars. I find them more useful than estimates floating around on the internet.
