Information on Engine lineups. 4.0L V6 option for the 2008 Liberty??

Jeepers shouldn't worry about the new 3.8L V6 engine in the current JK Wrangler. It was noted a couple a months back the DCX was working on a family of new V6 engines that would be used by the Chrysler Group as well as Mercedes.

Here is a list of the next generation V6 engines with a list of possible candidates for each of the engines.

1... 3.0L V6 base Phoenix (next gen LX, J1, L2, R2)
2... 3.0L V6 premium Phoenix (L2)
3... 3.3L V6 base Phoenix (current gen JS Avenger/Sebring, next gen RT Minivan)
4... 3.3L V6 premium Phoenix (current gen JS Avenger/Sebring, next gen RT Minivan)
5... 3.6L V6 base Phoenix (current gen JS Avenger/Sebring, current and next gen KA Nitro, next gen KK Liberty, next gen RT minivan, next gen LX, Grand Cherokee current and next gen, next gen Commander)
6... 3.6L V6 HEV Phoenix Engine (next gen RT minivan)
7... 3.6L V6 premium Phoenix Engine (current and next gen LX, next gen RT minivan)
8... 3.6L V6 PZEV Phoenix Engine (next gen RT minivan)
9... 4.0 V6 base Phoenix (next gen Pacifica, next gen NE Dakota, next gen Ram, next gen KK Liberty, current and next gen KA Nitro, next gen LX, next gen Grand Cherokee, next gen Commander, next gen JL Wrangler)
10... 4.0 V6 premium Phoenix (vehicles unknown)

The list of engines along with some discussion can be found here http://www.allpar.com/mopar/phoenix-engines.html

It should be noted that the Phoenix engines will start being available for the 2010 model.

For Jeep fans it should be noted that the new 3.6L and 4.0L V6's will find its way into the next generation Liberty (KK), Grand Cherokee, Commander, and Wrangler (just the 4.0L).

The 3.8L V6 currently found in the JK Wrangler is thought be to be stop-gap. With the 4.0L finding its way into the next gen Wrangler come 2012-2014.

so what about the 3.7??

Going byebye. But remember... this engine is a good ways out.... CY 2009 and MY 2010... this is assuming there will be no delays!

I don't want to see anything less than 3.7 on KJ. If not make it 4.0 standard with 3.0 sports or 2x4 models.

HEY! I have a Sport and I'd like to keep the larger engine. Screw fuel economy, I wanna be able to go! (biggthumpup)

Nobody knows the horsepower or torque ratings on these yet. Don't jump to conclusions. lol3.gif

New engines

These are to meet with new federal emission standards, which I think go into effect in 2010. The new engines will be more fuel efficient and cleaner running.

Generally, higher fuel economy means more you're squeezing more energy out of a gallon of gas. This can result in higher HP, but I suspect it will lean more towards fuel mileage. They'll probably play around with the gearing, tire size and several other factors.

Usually when you hear 'cleaner' you can assume lower fuel economy. I don't think they'll reformulate gasoline and catalytic converter technology isn't going to become more advanced. These new engines will probably be multifuel compliant. As far as cleaner burning the main pollutant of concern in carbon dioxide (CO2). You can reduce CO2 emissions by increasing combustion temperatures, but this will increase NOx (NO2, NO and N2O) emissions. This is probably where politics come into play.

All of this is complete speculation on my part.



I would prefer higher CO2 emissions, NOx emissions cause acid rain/fog/snow, and there is a whole plethora of problems around soil and water acidification. Carbon is easier to get rid of than nitrogen, both are greenhouse gases. The atmosphere is .5% CO2 and 78% nitrogen. Plants and the oceans absorb a lot of CO2. If the CO2 concentration rises, plants will grow bigger and leafier and counter the effect...for a while anyway. The problem with global warming is that we are releasing carbon, stored as fossil fuels, faster than the system can store free carbon. The solution would be to remove some carbon from the system. We need to find a way to convert CO2 and methane (CH4) to something solid...say like diamonds. This would end global warming and the people of the future would have to pay Zales two months salary for a freaking ring! Diamonds would be free, bling all aroung.

Global warming isn't going to destroy the Earth, but it might change OUR way of life.
