Posting this because people ask about the mileage:First 300 miles: 12.2 mpg mixed driving. 2 days were in below zero weather and gas had 10% alcohol mixture.

Get'r broke in with several thousand miles of towing long trips and running with a empty truck on long trips and some city driving then make a average for each and report back. 300 miles doesn't tell us much but thanks anyway as my wife is wanting a new 2500 4x4 crew cab with the new 6.4 in place of her little 1500 chevy crew cab 4x4 5.3 truck.

Posting this because people ask about the mileage: First 300 miles: 12.2 mpg mixed driving. 2 days were in below zero weather and gas had 10% alcohol mixture. My Ram/Cummins gets 20-21 mpg not towing. It gets 12 or slightly better towing. You obviously did not purchase the truck for mileage. 12.2 mpg not towing???

Had a 2005 Ford 250 diesel and never got 20 mpg not towing. Since it is not a DD, I would be perfectly happy getting mileage in the mid teens. We will see.

start an account over at fuelly and put a link in your signature noting your vehicle. Then people who are curious will be able to check your profile and compare mileages. Boy, 12.2 is a bit lower than what I was expecting to be honest, I was hoping to see 14 or 15 mpg mixed. But the thing is practically brand new. Get a good couple thousand miles on there and hopefully we'll see improvement.

I am assuming it will get better. Had a 2005 Ford 250 diesel and never got 20 mpg not towing. Since it is not a DD, I would be perfectly happy getting mileage in the mid teens. We will see. Hopefully it will get upwards of 16-17 mpg when broken in. 300 miles is not many miles to get a good handle on mileage.

Man you are not going to like this then. My HO with 2WD and 3:77 rear gears hits 26 all day long at 60 MPH, the best it's ever done was 30 running behind a big truck from Perrysburg to Dayton Ohio. Note I said tucked in behind a big truck. And yes I ask him if he was good with it via the CB.

As far as the 6.4 only getting 12.5 it's not even broke in yet. My bet is it is going to top out at 16 to 17 MPG. Not bad for a big block Hemi IMO.

Are you sure about the 6.4 being a big block! :R

Perhaps big bore would be more accurate. :W
Don

Are you sure? I do not think the 6.4 is the same block as the 5.7. There is a 6.1 super charged Hime coming soon and it uses the same block as the 6.4.

Don

Don,
I can't say whether or not 5.7 and 6.4 hemi blocks come from the same mold, but in terms of physical size I couldn't see a difference.

A 6.4L Hemi powered RAM will likely be my next truck.

Interesting read on the 6.4L Hemi Ram. Same warranty as the Cummins. 70% shared parts with the 5.7L Hemi that I know from my own experience is rock solid. I may be back in a Ram one of these days.

No pickup comes with a big block engine anymore. But the new small block trucks have more power than any of the old big blocks offered anyways.

The line between big block and small block can get sorta blurred anyways if all you want to look at is cubic inches. there are "small blocks" with displacements over 454 cubic inches. The difference between "small block" and "big block" really is mostly in bore spacing.

Interesting comment on battery price. A Toyota service manager that has replaced a few batteries under warranty told me the retail price and it was substantially higher than $1200 to replace the battery. But, what do I know, I don't drive a Prius.

Transmission for the truck, battery for the Prius... Dealer prices verses less expensive alternatives...

The 6.4L will report a wide range of MPG. The MDS activation percentage will affect the mileage. I've found that the truck will show a substantial increase in the mountains.
The MPG is the only one of the measure of the truck. Chassis performance is much more important to me. The truck will eliminate sway for most TT’s pulled. The rear coil spring suspension preforms better than the outgoing leaf suspension trucks, which were quite good in its own.

Local dealer let me take one out for a two hour test drive. I reset the trip computer before leaving the dealership. When I returned it indicated around 14 mpg. This was a mix of freeway, city, hills. When I returned it had around 100 miles on odometer (forgot to look what it was before I left). I should be taking delivery of mine in about 8 weeks.

My guess is that after break-in the truck not towing should get around 16-17 mpg.
