Exactly...you're the first person who has described what torque is CORRECTLY...it's low end power...and it is HP..just different units...kW instead of HP....you need power to make a car move...torque is a tangible, measurable way of understanding power...
Torque is a rotational force, power (kW and HP are both units of power) is the rate at which one does work, or work per time.
Power is what accelerates a car. Torque is a component of that power, as is the rpm. Therefore if you want to accelerate faster, you can increase torque or rpm (or decrease weight).
fyi...
In SAE units: Power (HP) = Torque (ft-lb) * rpm / 5250

Car and Driver is the only magazine I can stand to read, because the others lack content and straightforward opinion.
Just because their test results aren't consistent between cars they test and tracks they test them on has nothing to do with hypocracy.

Consistency isn't relevant? Think about that next time you're taking off in a Boeing 747 with the wings flexing 3 ft up and down...and then say testing consistency isn't important.

I guess you know how to use the spell check pretty well....
Honestly I just know how to spell. I also tend to become overly critical when I see people trying to insult one another. You see...I come from "the olden days" where people were actually responsible for knowing how to spell. We didn't always have a spell check feature....you are aware of that right?
Nice try though.

My point is if you take one Boeing 747 and lift off \"full throttle\" at LAX, and another Boeing 747 plane lifts off at YYZ with the same urgency, they are going to perform different.
I don't like your attidude, but have a nice day anyway.

They have anything but straightforward opinions....hey...I couldn't careless what you read...if you like it, more power to you, knock yourself out and read it.

I know power is what accelerates a car...that's what I said...and that's what kW and HP are...units of power. Torque is what we can tangibly measure from an engine...power is much harder to measure. YOU NEED POWER to accelerate...you need to have the engine running to produce power. Power is converted to torque...the more power an engine produces at low rpms (from long strokes and big bores) it is said to have more torque....or low end power.
Actually, power is just as easy to measure as torque. A dyno measures the torque and plots it with respect to rpm. Power is simply the area under this curve. I think you may be using the word 'power' to mean the seat of the pants sensation that you are accelerating quickly. You are right that this sensation comes from having more torque; and yes, the engine does need to be running
