Technologically...sort of...I mean semi engines have been able to beat that for many years.
In practical terms, once you can drag a 20k lb trailer up a steep grade without losing any speed or the engine struggling...it becomes mostly about who bought the bigger codpiece.
Our trucks still can't tow a 20k trailer up a steep grade at 65 mph. I can pull my 16k trailer up a 7% grade at about 50 mph with my 2017 Powerstroke.
Odd, I see lot of big 5th wheels racing up grades pretty darn fast.
Of course, as mentioned by others, peak torque at 1350rpm doesn't help generate HP which is what determines how fast you can climb a grade.
