Here is a few quotes from wk2jeeps.com:

"Building upon the standard Fuel Saver technology (four-cylinder mode) found in the new 6.4 HEMI V-8, a new for 2012 active valve exhaust system allows the technology to engage over a wider rpm range, which delivers improved fuel efficiency or the use of all eight cylinders when the power is needed. An active intake manifold and high-lift camshaft with cam phasing provides maximum low-end torque for impressive standing starts while optimizing high-end power"

"6.4L HEMI with MDS 465-470 HP (est.) "

Re: Any ideas what fuel economy will be for this pig?

AhhhhhHUH! Thanks!

Well, hopefully the highway economy will have an incremental milaeage improvent with MDS and the newer, more slippery body
Couple that with a larger tank, it might be bearable.

I think the 4cyl mode and any other improvements will just be overcoming the added weight of the new one. Either way though its gonna be bad ass!!
Eh. Its something that's my hobby. We all have our vices in life. LOL

With you making a thread like this, I see a WK2 SRT in your future. ahaha

Re: Any ideas what fuel economy will be for this pig?

I see this thing has MDS - when this "feature" first came out it was horrible...did they ever get this resolved. The surging on the 5.7?

I was relieved when the 6.1 came out without MDS - hoping the 6.4 is smooth and not noticeable....that would be ashame.

Yeah I didnt have any surging on my older 5.7 Hemi with MDS. Maybe he was talking about the issue some are having right now with their WK2 Hemi. I think thats isolated to cars built in a certain time frame. Should be fixed by now anyway.

The same to worse, I'll be honest. If you're worried about fuel economy, I've heard the new Prius is dope...

I have a commute too. I live basically in Naperville and I drive to downtown Evanston every day, about 80 mi or so. At this rate filling up 2 or more times a week with the stop and go traffic is going to get more and more crappy if this shit don't get resolved in the middle east.

I am ready to start thinking of an alternative to what I drive everyday. Good news is id be able to keep the jeep in the family but not use it any longer for the commute. I thought id never use the word hybrid around here but they are getting more and more attractive every day. With new models like the ford fusion hybrid, hyundai sonata hybrid and kia optima hybrid they look good while not being small and goofy looking like a prius or civic. Anyhow, where you head to every day for your commute?

Re: Any ideas what fuel economy will be for this pig?

There's really no reason for it not to get 20mpg on the highway. Full size V8 pickups have been getting that for the last 5 years.

Well compared to what it sounds like you do your gonna hate me lol. My commute is soo nice and easy and never any traffic whatsoever regardless of the time of day. Its exactly 20.0 miles each way and consists of almost entirely open 55mph country roads lol. I love my commute I actually almost look forward to the drive everyday (especially when I had my C6 Z06 vette). I drive from the Plainfield area (caton farm and ridge rd), up to where I work in Aurora on Indian Trail rd. So I take roads like schlapp rd and plainfield rd which I pass nothing but a few farms until I get into Aurora.
So this is one benefit I have going for me is that my fuel economy does not suffer from any harsh city driving that I lot of people have to deal with. In your case something more reasonable sounds like a smart thing for the commute then maybe you can get a seperate fun car.

Yeah that is pretty nice. For me however it takes an hour and a half on a good day to go from i-88 at Rte 53 to i-294 north to Dempster street, East to Evanston. Talk about stop and go most of the way during the normal rush hour. Lets not talk about bad days and how long it takes. hah
