4.7 Dropped for 2010

I'm very surprised by this. Seems like there are a lot of 4.7's out there.

[Redsand]

They don't need it, apparently the new V6 is gonna have enough power that will make having the 4.7 pointless.

[Knightrider03m]

They still have the 3.7L? I was told that the 3.7 will be replaced with the 3.6L. I'm shocked that they are going to remove the 3.0L from the U.S. line up.

[mjl2610]

In my opinion they should have killed the 3.7 and 4.7 in 05 when they came out with the redesign. It would have saved chrysler money and every one of those motors gets the same gas mileage when you look at it.

chrysler should not and I repeat NOT have thrown away the inline 6 ( Thanks Mercedes :mad: )

[Craig10114]

this move makes complete sense as far as the economics of running the business goes. A majority of people are buying the 3.7 for "gas efficiency"... and the ones who opt for the 8 are more likely to go for the hemi.. They drop the 4.7 manufacturing, save money there, and then get benefits from increased production of the hemi in buying materials in larget quantities.

They should have replaced the two with the Dodge Nitro's 4.0L

The I-6 was a old tried engine. The gas mileage was piss poor and the power wasn't better. The 3.7L was a better engine then the 4.0L

[Dylans3960ccs]

I've been passing poeple on two lane roads with stock everything hitting 80 with the A/C on every time and I'll just check the gas mileage tomorrow for ya. :)

[Dylans3960ccs]

I think the 4 liter just needs a good transmision.

Sad to hear...but I'm agree with everyone....people who want the V8 usually goes for the HEMI...so its a logical move on Chrysler's part...

If chrysler couldn't have a really efficient V6 option for the jeep in 05, it should have only the HEMI. TO me, there was no point in chrysler r/d and manufacturing to have the 3.7 and 4.7 which were basically getting the same efficiency acorss the board. The srt ofcourse would only have the 6.1.

Won't the 2011 SRT8 have the 6.4L?

[mjl2610]

Well supposedly the 2012 srt8 is rumored to have the 6.4L crate motor. I was just speaking in regard to the 05-i guess now 2010 models, screwin all the other motors and just havin the HEMI on the laredo, ltd and overland.

Yeah, I figured you were.

I mean if fuel efficiency is close enough to the others and it costs less to produce by going with one motor for the 3 trims, then I don't see why not.

Jeep claims/epa -

3.7 - 16/21
4.7 05-07'- 15/20; 08'+ 14/19 new ffv design
5.7 - 13/19;

I'm willing to bet the people on this site with the 3.7 get the same mileage as those with the 5.7.

[Dylans3960ccs]

I bet not b/c the people hired to testdrive for the EPA are terrible at maxamizing gas mileage.

Yeah, I know I get about 15.5 MPG and I believe most 3.7's are right around there as well. (keep in mind we can't factor in Joe's MPG - that just throws everything waaayyyy off, lol)

[mjl2610]

Yeah i mean when i was a little lead foot stop and go downtown for a few days straight i was hovering at 9.5-12.7mpg after fill up. If all you do is stop and go with these Jeeps the mileage really is awful. I try not to look at the evic anyhow especially if im always in stop and go. No need to worry about looking at the darn "average mpg".

Same here, I'll look at it every once in a while, but I keep mine on the tire pressure/CT.

I love how politicians complain about gas mileage/prices and are trying to alleviate the problem... well, how about the proper timing of street lights. Seems so simple and can have a huge impact on your MPG's - remember you average ZERO miles per gallon while sitting at a stop light, lol.

[mjl2610]

Absolutely correct but i mean i couldn't see dt chicago or any dt metro chicago area without a stop light every block, lol. Inevitable i guess. Im starting to get a bit...how do you say.. antsy or whatever about these gas prices rising again. Hope its not a "here we go again" situation.

I know 1st hand how fast (or should I say slow) the 4.0 is and I know how bad of gas mileage it gets.

[Redsand]

The 4.0 was not worth the sacrifice in power for the "make believe" MPGs everyone thought it was capable of. My 5.9 averaged about the same miles per gallon as the '04 4.0 WJ my mom had back in the day. At best maybe she would be 2 MPGs above me on the highway, and that didn't happen very often.

When it comes to more aerodynamic, lighter vehicles such as a car, yeah having a smaller engine will no doubt give you more miles per gallon. But when dealing with large, heavy SUVs, the difference each motor makes is miniscule.
