Hi Guys! I was just curious....for those of you who have a 4x4 QC 2006 with the Hemi and the MDS system - what are you getting mileage wise?? We have a '06 300C with the MDS and it does a lot better than my truck (see sig) If something happens to mine or I decide to get rid of it I was interested in getting an '06, but I would like some real mileage numbers first - not the b.s. thats on the sticker. Thank You!

 

I actually don't think it does that better than the regular Hemi. It is EPA rated at 14/19 I think though .

 

The only reported mpg saving is in the 45-55 mph range. When you get to highway speeds, the truck needs more than 4 cylinders to maintain that speed so the MDS isn't working. The MDS is great in theory, but just not practical on a full size truck. It probably has more to do with the fact that making one Hemi engine with the MDS is more cost effective for the plant than making 2 seperate Hemi configurations.

 

Using the gallons used by miles driven at fill up method. I get 14.8 city and on a 240 mile hi-way trip right at 16 mpg,with 1200 miles on the clock.

 

The only thing I can say for sure is that now I have more miles on my truck, it gets better gas mileage and it feels like it has more power, if I drive mine and a new one back to back.

I drove a 130 mile round trip on the highway the other day. At a sustained 75mph using the cruise, the overhead said I got 18.6 mpg. Usually a little optomistic, but normally within 1 mpg, so I consider that to be pretty good.

 

Thanks - keep it coming! I get 12-12.5 with my '01 with the 5.2 and several mods. Sounds like I need to upgrade one of these days.....

 

Bump up ^^^^^^^

 

usually around 14 city and 17 to 18 highway. If you catch the wind just right I've gotten 19 driving 200 miles to Houston.

 

15.5 - 16.6 overall. I spend most time on the highway with the cruise on. Much better than the 11.5 my old '01 5.9 used to get.

 

Good Lord! do any of you guys use the gas or do you guys roll down the road. lol i cant get about 11.0 city and about 12.0 e-way...am i the only one who uses the hemi for the power here??? 3500 on the odo. "madman"
