Different CVT possiblities in the future?

The MK CVT's are produced by Jatco Ltd. Right now the MK's are using the JF011E model, which is rated for 2.5 liter engines and lower.

However, there are also CVT's made by Jatco that are capable of handling higher torque capacity and up to 3.5 liter engines. The JF010E is an example. This CVT is currently used on the Nissan Murano.

I have to imagine that in future models, Jeep may opt for one of these units. Perhaps the higher torque capacity would allow for a diesel engine/CVT combination (more torque and even better mpg). Perhaps it would allow for a lower "crawl ratio" for the FDII models (maybe 25:1 or something along those lines).

Couple that with the interest the MK's are beginning to garner with aftermarket suppliers, and we could see an even more capable set of vehicles in the future.

Here to building off of the successes and learning from the failures of 1st year models.

I've thought about the use of the bigger Jatco CVT but that won't necessarily affect your final drive ratio. The range on both the CVT2 and the CVT2L is 2.35 - 0.39. It's the final drive that gives the crawl ratio; a final drive of 2.41 is mated with the CVT2 and 3.21 is mated to the CVT2L. That coupled with the other program features of the Off-road mode is what sets it apart. Since the crawl ratio is created by the final drive you're also lowering your top end for freeway cruising. There has to be a compromise since there is no Hi - Lo range.

How about with a 3.3 V6. Anybody got a shoe horn?
