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.
