Not to get into a physics lesson here, but the statement that "torque is what gets the work done" isn't really true even though you see this repeated frequently. You can have all the torque in the world but it takes delivering it at some rate (in other words, motion) to get anything done. Think of a wrench on a stubborn bolt - if the bolt doesn't turn you have done no work even though you were applying torque. This is where the "power equals torque times speed" equation comes in - it is power that actually does work. Increasing the amount of torque you can deliver to the drive wheels (which is the only place it really matters) is as simple as downshifting but of course you will be moving slower. This is why engine power, not torque, determines how much work you can do in a given amount of time.
The reason that diesels feel stronger than a gas vehicle of equal power is that, because of the greater torque, the peak power is produced at a low engine speed that is usable in everyday driving. Most of us don't normally rev the gas engines in our vehicles to the 5000+ rpm it takes to deliver peak power so the potential goes largely unused.

No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
