Car parameters

This article discuss how the car*.res parameters control the performance, handling, aestethics and other aspects of a Stunts car. A quick reference chart of those parameters may be found at the Car files article.

Engine and Transmission

Torque curve

Address: 60h-C7h Defining how much acceleration the engine can impart on a car at every given engine speed (rpm), the torque curve is naturally a very important factor in determining performance. Every byte corresponds to increments of about 125rpm. The curve works as expected: raising a byte increases linearly acceleration at a given rpm. A more peaky torque curve means a narrower range of useful engine speeds - and thus, the driver will have to shift more often. Another important point is to remember adjusting offsets 32h and 33h properly depending on where the torque curve is intended to end.

Number of gears

Address: 26h

Self-explanatory. Valid optoins go from 1 to 6 gears. Note that for a 6th gear the appropriate parameters will have to be defined elsewhere.
