Mpg

I am going to be getting a commander with in the next 6 months and I went and looked at them this weekend to get a feel for the interior and noticed that the 4.7 gets 1 more MPG city than the 3.7 v6 I was originally going to get a 3.7 but now I am considering the 4.7v8
Is this correct or was it just a miss print what are you guys getting with your 4.7v8
I plan on putting a K&N in and an exhaust

Also dose the limited come with the 3.7 or just the 4.7 & HEMI ?????????

This is correct because the 3.7 has to work harder to move the heavy Commander. We have several members here who love their 3.7, but many more with the 4.7 who will tell you to get the V8 for many reasons.

The 4.7 seems to be better all around. The drivetrain is better for offroad with the low range QTII. Those who have driven the 3.7 say it is sluggish on acceleration. If you plan on a lift and tires some day the 4.7 is the best choice.

I wouldn't say that exactly, the milage on the 5.7 isn't much off of the 4.7. If I could afford it I would have gone with the HEMI. If you still think the 5.7 is "wrong" I will be happy to swap engines with you. LOL

Hang on there CUPRA,
I also have the 4.7 and consider it a very good engine as well,,,,,,but, if I was to ever do heavy towing [I have a F/S Chevy truck for that] or a lot of mountain driving I would consider nothing less than your 5.7.
There really is no replacement for displacement, especially when trailer hauling.
Sure, the 4.7 will do it, but it'll be working its a** off, and, because a deeper throttle position would be required to pull that load, the 4.7 will get poorer mileage.
My opinion, you have the right engine for your potental needs and will not wish you had more if you were hauling a boat or something.
..........Rob

Go for the 4.7, its definitely worth it over the V6. If you're towing, get the Hemi unless you're buying a 2008 or later, then the 4.7 will be fine since the power numbers are similar between the two.

I agree with what's been discussed. The 3.7L models were doing 2mpg better than the HEMI via highway (can't recall exactly on the city mpgs). Indeed I settled for the 4x2 Limited w/ the HEMI. Here in Houston, we can do 4x2 b/c it hardly snows, and well, when it floods, ya not driving through the swamps hehehe! It has served well through the massive rainstorms we've had, let alone future hurricanes ..."Come on Ike, we're ready!".
