Torques

Try these two cars I quickly whipped up. Identical except for the drivetrains in each.
One makes 150Nm and the other makes 600Nm and yet they lap and drive the same.(at least too close to call)

caveat: The sounds will make a big difference to the feel of each car and the friction and inertia values for the drivelines can't be made precise.

Statements like: 'Power for top speed but torque for acceleration' and similar is what I am calling out as BullShit!

That's an interesting experiment. There's generally a lot of confusion around torque and power. I've certainly seen it in discussions about calculating optimal shift points.

I remember that thread, over at the official forum? Turned into a lot of people violently agreeing with each other.
Somewhat solidified the idea of my 'Torque is meaningless' line I add to my mods, as to the lay man that's exactly what it is.
Torque, of course, is important for thermal and mechanical efficiency but even then the number alone means nothing, you need to know everything that is contributing to that number.

Remember that at any given speed, for a given Power, the Torque at the rear wheels is identical, no matter what the engine may be producing.
