The main point isn't time savings though, but to lower the operating costs associated with fuel and maintenance. Time is a bonus.
It is a trade off between time and money. Class 8 trucks vary wildly in engine specs anywhere from 250 to 600 hp and 1000 - 2000 lb-ft of torque. Plenty of trucks can maintain speed on grades but doing so burns a huge amount of fuel. (Just like blasting up a grade at 80 mph depletes a battery very quickly)

The problem with Tesla's claims is that they don't tell us the diesel truck they are using for comparison.
