This time for sure: 2012 Wrangler gets Pentastar V6, 5 speed auto

A report in the Toledo Blade says the 2012 Wrangler will be powered by the 3.6L Pentastar V6. A 5 speed automatic transmission will be available. The six speed manual will continue to be the base transmission.
http://www.toledoblade.com/Automoti...et-for-Wrangler-V6-engine-transmission-2.html

Why the excitement? The 3.8L V6 under the hood of the 2011 Wrangler produces 202 horsepower and 237 pound-feet of torque. The Pentastar V6 is rated to produce 290 horsepower and 260 pound feet.

According to Allpar.com, the Wrangler's EPA fuel economy ratings for 2012 are improved by the new V6 and 5 speed. The 2011 Wrangler with automatic was rated to deliver 15 mpg city, 19 highway. For 2012, the EPA says 16 mpg city, 23 highway.

Jeeps in Europe come with a new 2.8L diesel and 5 speed automatic transmission that produce 300 pound feet of torque and get 35 mpg. Just sayin'.

Have several friends who work at the Jeep Plant and they have been telling me for a while now about the "upgrades" I get several "unofficial" reports from them on what the new things will be etc. They've been building them for a while now already or at least a few have passed through the line getting ready.
The upgrades will be great

IMO the more important upgrade is to the five speed auto. The previous 42rfe four speed has just too big a leap between the 1:1 third and the .67:1 overdrive fourth, resulting in too much drama on any downshift at highway speeds.

Waiting for my favorite salesman to give me the word. Ordering one from the factory the day they are available.

Wow, I may actually look at a JK now! Their pathetic excuse of an engine was a major deciding factor for me a few years ago when I was thinking of buying one.

What other upgrades are being done?
It will be some time for me I just lifted my 2004 Rubicon and getting ready for new tires.
Also just have over 90K miles and prepared to make it another 90K :).

Am I wrong..?
I think some where you are being misled about the mpg of this combination, especially if it was offered in the states.
It gets into the upper twenties in a "much" lighter 2005 Liberty. So I can't see it getting 35 in a JK, just ain't gonna happen here stateside anyways.

In Europe.... And Mitsubishi has a turbo diesel pickup from the 80's or 90's that was sold here that averages in the 30's per gallon, a local guy has one on 35's that averages 32mpg.

VW has a tdi motor overseas that sees 60mpg AND would meet US emissions standards, but we will never get that one here either!!

38 MPG in UK gallons would be 31.7 in US gallons...

Its confusing though because the website actually says:

EC Combined - mph (L/100km) 34.0 (8.3)
EC Extra Urban - mph (L/100km) 38.7 (7.3)
EC Urban - mph (L/100km) 28.3 (10.0)

I suppose the mph is a typo and should be mpg?

Guess I should do the metric conversion of the L/100km and see...

My manual 6 speed diesel crd 2009 jku wheeld 90k km (56k miles) in last 2 yeaes and I can tell you that after i put the arb front bumper + m8000 warn + alu asfir front skid + 32" bfg (3:73 gear ratio) the consumption is not the same any more as with stock configuration and i had to tune up the engine from 177 hp to 210 hp getting now 468 torque (from 410nm) to feel the same initial crd vm engine.
My jku real:
- mixt consumption is 12,5 l/100km (18,81mpg)
- urban consumption is 13,5 l/100km (17,4 mpg)
- highway consumption (80 mph drive not loaded just with above settings) is 11 l/11,5 l/100km (21,38mpg)
The above conversions were made usinghttp://calculator-converter.com/l_100km_mpg_convert_mpg_to_l_per_100_km.php
Diesel 2,8 crd 2009 Vm crd engines are kinda sensible with kit tunings if setting was not tested and proper setting is proper performed. I've experienced twice limp mode because of wrong tuning setting. Tuning helped me stabilizing diesel consumption about 0,2-0,5 l/100km.

For 2012, the EPA says 16 mpg city, 23 highway.

Wow. Just wow.
If this is accurate, in the year 2012 Jeep are selling a vehicle that gets 16 MPG city. SIXTEEN!

Pick your adjective of chocie: (I pick all three)
Disgrace, Pathetic, Mistifying
