It may be an exaggeration I dont know , but it could just be people being in touch with their car and knowing how it should be driven , the ratings are only estimates and with manuals vs automatics greatly vary.
I was making a poor joke when I said the v6 dragged it down , I know a few people who like to average cars gas figures as a whole not separately when comparing cars. Personally I think thats nonsense but thats where the post came from.
Also I agree , I think the 2.8 is also I dislike anything that doesnt have variable valve timing
