It is a curve that usually looks like a mountain, torque increases to some mid RPM, then starts to fall off at high RPM. But engines can be tuned for different shaped curves. The 3.6L has a fairly flat torque curve, and I have seen some after market tunes than make it really flat. Torque x RPM x units constant = HP.A review of a Wrangler states that the Wrangler can achieve 260 lb foot of torque at 4,800 rpm.
What is the link between torque and rpm?

Torque is not power, it is a measure of rotational force. You can have lots of torque with no power. Power is a measure of the rate at which work (force through distance) is done.Torque is how much power an engine can make. Horsepower is how fast it can do it.
That's why a diesel can pull more weight, but does so slowly.
The 3.6L engine doesn't make much power, but the power it does make comes on quickly (high horsepower) and the powerband is nice and flat.
Rotational force is power.Torque is not power, it is a measure of rotational force. You can have lots of torque with no power. Power is a measure of the rate at which work (force through distance) is done.
A deisel pulls hard because it creates a lot of torque at low RPM. It may not produce much HP since it won't rev very high.
The engine explodes at 4,801 RPMAs I push the accelerator, the rpm's increase and the torque increases, helping me over a rock. If the rpm's actually reached 4,800 and I have not moved, that implies when I do move, I might fly over that rock and damage the vehicle.

Can't do it. Off to the next thread.And here it goes...
