Horsepower is horsepower?
If that theory is true (in real circumstances), then a 385hp 6.7L Cummins diesel shouldn't spank a 381hp Toyota Tundra when both are tested 0-60 towing a 5740# boat. But it did. Must be the adva...

Continues to be the marketing metric....HP sells
Out of context, as there is more to it
Or that HP is developed from torque. There can be torque with no HP, but
HP can NOT exist without torque. Why out of context just talking HP. Other
attributes to any discussion on HP are the other factors (attributes): RPM,
gearing in the tranny (both auto and manual), diff and the effective final
ratio to pavement (tire dia or rev's per mile factor)
The concept of torque without HP but HP can not exist without torque is lost
to most. Might help to see the formula HOW2 derive HP (generic)
HP = torque (ft/lbs) x RPM divided by 5252
It can get more complicated, as there are different kinds of 'HP'. Like 'draw
bar', 'brake', 'shaft', 'SAE gross', 'SAE net', and a big ETC...
Things like a high HP @ high RPMs might not be able to get the load going at
all, but a high torque ICE can easily...to then have that high torque ICE
lose a time to speed contest
But the bottom line is that HP sells and is all most folks ever care about. Plus
a time to speed race is the other thing they care about...
