How to use the Powertrain Visualization app

If you hover your cursor over the icons it should tell what they are.

 

Blue is 'given' torque, orange is 'received' torque.

(Ie. it's blue if you accelerate, it goes orange if you let the car roll, as the wheel friction is slowing down the vehicle)

 

It's a bit of a mix and match of power and torque.
Line width displays absolute power while the color indicates the torque sign.
That's why it's orange in reverse (after the gearbox).
