Eaton 10-speed manual vs. DT12 AMT, etc.

What year is your P4?
The P4 Cascadia was a big jump over the P3 Evolution. I believe the official number was an 8% fuel economy improvement. The Aero X package that came out in 2019 on the 2020 models is good for another 5%.
Lots of improvements coming in the future but they are harder and harder to find.
