The 2014 Cherokee with the same engine and tranny (8sp) is rated at 30mpg, I would expect the truck to be closer to 28mpg.

Possibly, but the weight difference between a 1500 and a Cherokee is surprisingly small, some configurations of a 1500 will actually be lighter.

Fckn idiots, they should have stuck with Cummins like they were going to do back in 2010 or whatever.

Cummins are just flat out reliable. That's why we use them so much in the fire service. Many heavy duty ambulances on International chassis's use the Cummins/Allsion trans combo, and you can't beat it...

In this case its the Aero that will make the difference, the Cherokee is much more Aerodynamic than a Truck, though there are things you can do to improve a Truck. A back half bed cover helps a lot, the spoiling air behind the cab has somewhere to go, the flowing air over the top flows nicely across the cover as it joins the low pressure area behind the Truck...

I was planing to replace my F150 next year, with another F150. This could be a game changer if the price is reasonable.

The cummins diesel 1/2 ton gets 18-ish at best. I drove one from TN to Florida and I averaged mid to high 18's on the trip.

It also makes a lot more power than this though.

A quick google search reveals the drag coefficient of each vehicle is (2013 RAM Vs. 2013 Grand Cherokee)

2013 Grand Cherokee
DRAG COEFFICIENT 0.37 Cd
2013 Ram 1500:
best-in-class aerodynamics (cD = 0.363)

I'm not certain, but I think the last VM Motori engine in the Liberty CRD was a disaster.

Power is King. :D

They should just drop a 4BT in it and a good sized turbo and call it a day.

A friend has 3 of these. They run good if you keep the oil cycled regularly. But they are a bit tempermental. They are all the 2006 Limited Edition, the 4x4 in those kicked ass.

I didn't know they offered a diesel in any half ton pickup.

A google search indicates that the new Ram will be the first half ton diesel ever. Perhaps you were mistaken?

You're right. That was not a 1500.

I'm not up on pickup trucks ;)

I was assuming you drove one of the prototypes, as I'm pretty sure they got that far.

Oh you meant the 2500/3500 with the 6BT motor. Back in 2010 Dodge was planning on putting a V8 Cummins in their 1500.

Depending on the year you drove it was either a 5.9L I6 or a 6.7L I6. The 6.7 was released at 2007.5 and getting over 18mpg out of them with the stock emissions is a bit difficult. The 5.9 is capable of getting over 20mpg.

Thats close enough that the additional frontal area of the truck means it has more drag. :colbert: :colbert:

Could you run through that logic for me, cause I'm confused.

Coefficient of drag is relative to the frontal area of the object (the cross sectional area). The SHAPE of the RAM is more aerodynamic, but it's taller and wider than the Grand Cherokee which more than cancels out that advantage.

Motorcycles usually have MUCH higher coefficient of drag than cars, yet their cross section is maybe 1/3 as big, so they get like 50mpg highway.

I understand how it works. But statement I quoted sounded like he was saying that even though the CD on the two vehicles was near equal, the truck had higher drag because of it's frontal area.

The one good thing I see coming out of this is that GM & Ford will be forced to finally put a diesel in a 1/2 ton as well...:thumbsup:

Then we shall see some real numbers...;) (still waiting on the 4.5 Duramax)

Maybe soon as GM does it, but when Ford does it we will just have another truck to laugh at. :D

This. I assume they never did it because it would bite into 3/4 ton sales.
I'm planing on replacing my truck next year, and if the diesels are reasonable, I'll be buying one from whoever makes it. These should have been on the market ten years ago.
