The EPA ratings are specific to engine + trans combinations available for that vehicle, the numbers and link I posted are for the 4 cylinder 5 speed, which was the BEST combination for that year.
The tech4/ iron duke/ 2.5L engine is an archaic piece of equipment that is more comparable to a farm tractor engine than any of today's automotive motors. They are tough as nails but when it comes to efficiency they leave a lot to be desired (large bore/ short stroke = less efficient combo at low RPMs).
