Cheat Sheet: Vehicle Properties

All the properties that make your car go fast (or slow)

Summary

Created: Jul 9, 2022 by jato Last documented edit: March 29 2025 by manavortex

This page lists those properties that control how a vehicle behaves. By changing/tweaking them, you can modify a vehicle's behaviour.

Wait, this is not what I want!

• For a guide on adding vehicles, see Boe6's Guide: basic car from A to Z

• For a guide on how to visually change base game vehicles, see Altering Appearances within Wolvenkit - Full Workflow (the process is the same for cars)

• If you want to know how to change an existing car, check Tweak modding: Guides, for example Adding stats, modifiers, and mod slots
