According to this calculator:
Horsepower calculator
If the Ford weighs 8600 lbs and accelerates from 0-60 in 8 seconds it has about 440 engine HP.
If the Duramax weighs 8600 lbs and goes 0-60 in 8.74 seconds it has about
390 HP.
And if the Ram weighs 8600 lbs and goes 0-60 in 10.2 seconds it has about
320 HP.
There is no way that these trucks vary this much in horsepower.
Does TFL do instrumented testing? Do they account for different conditions when comparing various tests? I read an article once about how Car and Driver does their testing and it was pretty elaborate. FWIW, their 0-60 on the new Powerstroke was 7.2 seconds versus 8.2 seconds for a 2014 CTD Ram. Both were SRW models in the same configuration (CC/SB 4wd).
