I just test drove a 2021 limited with a 5.7 etorque (3.92) and a laramie 5.7 no etorque (3.21) and the limited seemed to lag a lot off the line compared to the Laramie. The Laramie was responsive and the limited felt sluggish, does that sound right? I am very confused by this experience.
Aside from weight (and that is dependent on options), the Limited has the advantages of both eTorque and a 3.92 rear end.
I specifically ordered my Longhorn with both options in order to overcome the sluggishness I felt when test-driving non-eTorque trucks with 3.21 gearing. And in my review of the first eTorque truck to show up on a dealer lot, I demonstrated that it was possible to break the tires loose
while starting the engine, so even start/stop isn’t a disadvantage for eTorque.
It may just come down to a difference in pedal position, seat position, or current transmission profiles (there are 45 shift programs that can be learned based on driving style). It also could be a difference in “feel”—but not necessarily speed—due to the Limited’s air suspension, presuming the Laramie has coils.
Good luck to you!
