To add to Dirt Bike's comments, possibly the 3.7L/vehicle combination is more efficient than the 3.5L/vehicle combination.

In the bad old days, I once had a Mercury Marquis with a 429 cu in engine that got better gas mileage than a Crown Vic with a 350+ cu in engine. The bigger engine was in a slightly heavier vehicle, but it was a more overall efficient design system, so it did better.

Let's just keep the comments relating to the subject and away from those posting them - PLEASE!

How is that "adding". Dirt Bike Dave is basically pointing out that while their could be reasons, it is possible the EPA is wrong. It force one to wonder how this could be the case and to further wonder why Ford wouldn't challenge the EPA findings if erroneous. That fact is that no one has disputed that the 3.7l is getting better mileage. All I am asking is why? I am further postulating that the turbos are not used in EPA testing because the only way anyone gets their numbers is to drive with a light foot.

 

Ok, since we have two mods in here let me ask a simple question. Is cross posting now legal in this forum? I was under the assumption this was frowned upon in this establishment.

 

I think, I've given a possible "why" answer to your question, Rex. Is it the actual reason? Maybe, maybe not. But there are too many variables to account for and we don't have the actual lab data.

Does the EPA get their results driving the vehicles the way the average owner does? Of course not. They supposedly do a better job now than they used to, but it is still an "artificial" test under carefully controlled conditions. About all it can be used for is to compare two different vehicles to see which might be more efficient.

Wookie, it's not "illegal", but it is frowned upon. We try to combine/eliminate crossposting when we become aware of it. And, we advise the OP doing it that we'd like it to stop.

I checked on this and you are correct. I found a link as well. I'm not sure the epa does most of the testing. Here is a linK: http://www.caranddriver.com/features...economy-page-1

However, you are still running a larger engine through the same tests as the smaller eco and the larger engine is getting better mileage. The fact is too that neither engine is being driven anywhere near full throttle. The reasonable conclusion is that if saving gas matters, get the 3.7.

 

If this objection is what I think it is, I tried to delete my post in the power train forum and I all but did so. Wookies real objection might be to a very legitimate point.

 

I asked because this exact same thread was started in the "Other Powertrain" section but with a different title. I'm sure the second one was started here to get more effect though.

 

OK, I've deleted the thread in Other Powertrain. A normal forum member cannot totally delete anything he has posted. He can just edit it to remove the contents, which is what he did.

As to the reason for opening the subject here, I cannot and will not comment and I ask that you leave it alone too.

Not a problem, I keep that user on ignore because of the incessant pot stiring.

 

looks like out friend is on vacation..

 

I'm fresh outta the penalty box myself. I gotta be good.

 

Knock it off, Coy. Like Rockpick, I'm really tired of the posts that take jabs at other members. Don't test me.

That's a great question. Why is this thread all over the place and no one will answer the question? Are people always this rude?

 

So why is Dirt Bike Dave saying the test is invalid?
