The handling.cfg file is a text data file format which sets many performance and behaviour values for each vehicle in GTA III, GTA VC and GTA SA. The file can be opened and edited with any text editor.

GTA III

Standard Data

This section contains all the performance settings for land vehicles and provides the base settings for boats, bikes and flying vehicles. The special behaviour of boats, bikes and flying vehicles are hardcoded in GTA III and are not included in the handling.cfg file.

The below table provides the column letter, column name and a brief description for each setting available in this section.

Column Letter Column Name Description
a vehicle identifier Relates this data with default.ide and other files.
