I guessing a possible reason maybe is to minimize the engine's time of being in boost. This is a way to reduce stress on internal components.I did answer you, because it doesn't need a higher gear ratio. Why would Jeep put any higher, or lower at that matter final ratio than necessary for optimal performance, fuel mileage, etc??? This isn't your Dad's old CJ with 4.56 Dana's designed for crawling around, with a top speed of like 65. There's a lot of factors that go into it, optimal powerband range of the engine, the fact that we have a 9 speed transmission, and other various parts of the math equation, equal what we have. Also the fact that final overdrive gears (plural) in the ZF9 are obviously pretty high as well. I'm just guessing, but I'm going to say the overdrive probably starts at around 7th gear???😎
This way to extend the engine's life before it goes Boom.
Thank you for admitting the 3.2 L V6 is a superior engine
3,2 V6 L vs 2.0 T argument is settled.
