I think the hardest to understand in comparison is how the HP/torque works in real life.
We just replaced 174 HP diesel sedan with the same model 230HP gasoline model.
At 2-3000 rpm cruise the gasoline engine feels week. It has to downshift, where smaller diesel would do fine on top gear.
It takes >4000 rpm for gasoline engine to show the power.
It can be. TQ = F X r where r is the distance from point. Or r = distance from hub to ground.
W = F X D where W is work and D is the distance you exert the Force.
and P(power) = W/t where t equal time.
So any reference that has time in it, like speed or acceleration requires power. That is horse power. So you accelerate and climb hills at best HP rpm. Simply put TQ says how much weight you move HP says how fast you do it.
I know you understand this, many don't.
