So they’re trying to make the Sport more fuel efficient.. and then they cut its legs out from under it by upping the axle ratio from 3.21 to 3.45?Would make more sense ifmit was required for the diesels, but both domestic and export get the 3.73, so that’s not it.First gear ratio and overall spread will increase dramatically in the Automatic, so much so that in an auto the old axle ratio 3.21 on the ZF would’ve had a much better crawl ratio and better final drive than the current JK auto with a 4.10 axle.My concern is that the reason they picked this ratio is to accomodate the manual transmission which they might not have been able to get as high a first gear ratio as the ZF’s 5.0:1 and as good an OD 6th gear or as full a ratio spread. 3.45 axle in the sport makes sense if the manual transmission’s first gear is 3.x-4.0:1 like in some Tremec 3160s and the gasoline version of the ZF S6, where 3.45 axle on a 4:1 first gear would still be a lesser crawl ratio than old NSG 6-speed and a 3.21 axle, you would need a 3.55 axle to almost match the old 3.21 if they weren’t able to get a better 1st gear.Not reassuring from either a CAFE or manual transmission perspective.For my daily driver it doesn’t have much of an impact as 3.73 was still the target even with the new automatic 1st gear and OD & Spread boosts, and for the cottage won’t make much of a difference, and a lower 1st gear than the current NSG would make a more relaxed 1st gear for puttering around town and leisurely country drives. But the implications are interesting.
