Power Band Acceleration
These are the engine torque values for each part of the power band. When comparing cars, higher numbers mean faster acceleration through that part of the power band. Engine Balancing may change these values as it sometimes changes the power band

Texture Sheet

Note, the game uses 16 separate palettes of 16 colours to correctly show the car for each colour it is available in. These images show only the first & second palette of the first colour since I don't know how to map the correct palette to the correct part of the image.

Power upgrades are multiplicative when stacked. For instance, if a car has a Turbo which adds 40PS from stock and an Intercooler which adds 20PS then upgrading both will add more than 60 to the car's PS. An app to model cumulative upgrades is available here
