So given the miles per gallon and cost ratio and for how long it would take to actually break even on the engine difference what exactly do you see as a benefit comparing the turbo to the 6?
Well, from what I have read about it so far, a higher torque rating at a lower RPM vs. the 3.6, and a lower 0-60 time vs. the 3.6. Like I said, I’ve always preferred 6’s in my Jeeps (I’ve owned 13) previously (unless a V8 was available), but I’ve also owned two cars with 2.0 turbos (VW GTI and Audi A4) which were quite fun!

Do you have the documentation or article that states what the turbo’s torque is and at what rpm? I could care less what the 0 to 60 time is. My new V6 JL won’t be raced down a quarter mile drag strip.

Somewhere in one of the LA auto show videos they mentioned the peak torque around 3,000-3,500rpm. The engine itself has 270hp and 295lb/ft of torque.

Not sure how reliable these sites/blogs are, but they all say the same thing, basically.

Also at what percent throttle as boost builds? The fact that it makes more torque at a 100% open throttle at lower rpms is not beneficial to me, others may feel differently. Being able to more finitely and judiciously apply torque to the wheels is more important for me personally in a Jeep. Ymmv

For what it's worth TFL mentioned they'd rather have the 2.0L but they only tested it for a few hours offroad with a Rubicon.

There is nothing definitive I could find on the V6’s torque. The latest Pentastar revision says the torque was increased 14.9% between 1k and 3k rpm due to a new variable valve train and increased compression.

Would very much like to see the rpm vs torque curve on these two motors. With these definitive curves in view, we will know which is for street or trail.
Couldn’t have said it better.

It may be the V-6 remains in the lineup for true off road capability, add larger tires and wheels, it may then be the clear winner. Once the diesel appears, the race, or rock crawling, begins as to which works best.

BINGO! :like::like::like::rock::rock::rock::rock::clap::clap::clap:

Yes, that is where I saw it. So instead of the $2,000 for Auto, going with the Turbo engine and Auto would be $1,600?

How could the Turbo engine be cheaper?
I'm guessing (along with others in that thread) that Jeep is making the 2.0 turbo cheaper than the 3.6 w/auto because they want people to choose that route for CAFE numbers. They know the majority of Jeeps will be sold with the auto trans. I'm certainly curious about it but I want an official number before deciding.

All (official) hp/torque ratings are measured at 100% throttle...

Thats my point. In an off-road situation where you’ll likely be at at a partial throttle opening the boost will need to build and then will spin up the torque too quickly where you’ll have to back out of the throttle and attempt to renegotiate the obstacle. Naturally aspirated engines deliver a linear torque application which is much more appropriate for this vehicle although an argument can be made for boost at altitude if the alternative is too anemic.

Have to agree here, while maximum torque is an important figure, the torque band just off idle and throughout the rpm band is the useful information. It determines usefulness in real life situations. The best for street may not be the best for trail.

Oh, I must have misread your post. Those were the specs of the 2L turbo. I don't think the specs of the Pentastar have changed at all. I think what's giving the Jeep better fuel economy is the 8-speed auto.

The question is whether or not that initial $2,000 / $3,500 number was correct but reversed, or just as far off on the $3,500 as the 368HP 2.0T.

The ~$1,400 2.0T-Auto vs $2,000 for the 3.6L auto would make the 2.0T the lesser engine justifying the -$600 in the platform again, though not the ‘base’ engine as it’s not available without the auto. The $3,500 or $1,500 premium, would make sense if it’s a ‘premium’ engine, so it’s still questionable how it’s positioned. The only way the $2,000/$3,500 makes sense right now that the 3.6 auto is $2K is if the $3,500 is for the 2.0T, but again that could have been way off.

It does make sensefor the $1,400 from the CAFE standpoint, but also if it is the weaker engine on its own, so that once the Pentastar gets BSG in 9 months, then it’s hard to justify paying more for the 2.0T.

edit: Another thing to consider is if they market the 2.0T heavily as a hybrid, as has been happening in early reviews touting it as Jeep’s first Hybrid. If they do that I can see that $3,500 number making it into the mix just for the sheer marketability of the Hybrid portion, even if the benefits are truly as mild as the hybrid itself.
