Ford V10 vs Pending V8
I understand Ford has developed a 7.3 liter (IIRC) V8 as a replacement for the 6.8 Liter V10 that has been around for some time. I've also been told the 2021 model Motorhomes come out in March, 2021....

My point wasn't that the 10-speed isn't capable (it is). It's that the rest of the current E-series driveline can't cope with the extra torque that would be delivered by the lower gearing in the 10-speed, so they'd have to limit power in those gears. The E-series is still using a Dana 80 housing with a modified carrier for 10.75" gears and a small-ish driveline. All F-series are now running the Dana M series axles.
BTW - Tuning and certification for the 7.3L is now common to the E & F-series over 14,000 GVWR (and Ford claims power levels are the same, only the certification method differs). Exception that fleets can select the "economy" tune in the E-series. There just isn't much advantage to stuffing the 10-speed under there unless they also upgrade the rest of the drivetrain. Which I hope they do. But they already previewed the 2022 changes, and it's limited to an smaller doghouse. No drivetrain changes were posted.
Well, that's good that the engine power isn't de-rated. Cause that sort of reduced the appeal of a big new powerful engine.
I still don't buy that the rest of the driveline can't handle it. The Dana 80 isn't overpowered by that torque, by a long margin and the stresses aren't appreciably less. First gear is still pretty deep on the 6 speed 4.2? ratio vs 4.5? ratio on the 10 speed. And even if the driveshaft is at it's absolute limit with a slightly taller gear ratio of the 6 speed, It's an easy change to shore that up.
Bottom line, IMO it's price point thing. Vans and cutaways are utility vehicles not performance vehicles in the least.
