Vehicle Physics Pro
Advanced vehicle simulation kit for Unity 3D providing fully realistic and accurate vehicle physics.
Project under development: Pre-Release stage
Pre-release stage means the project base code is completed and it's safe to use it in production projects. At this stage I'm working on the demo scenes, vehicle examples, 3D and other art, etc. VPP may receive bug fixes and minor feature improvements before the first release.
This documentation is being actively written and updated. Some pages are yet to be completed.
Early Access to Vehicle Physics Pro is now available with the Professional and Enterprise licenses. Learn more

- Advanced AAA+ vehicle physics simulation
Built around an accurate physics solver providing realistic results for all vehicle types and setups. The precision of the numeric results depends on the integration steps only.
- Modular powertrain design
Vehicle dynamics core is implemented with functional blocks with inputs and/or outputs that can be connected in any number and combination. Any vehicle setup can be emulated by arranging and connecting blocks. VPP includes standard vehicle blocks such as engine, clutch, gearbox, differential, torque splitter, and more.
- Advanced wheel and tire friction simulation
Provides accurate friction values in all situations. All torques acting in the wheel are properly combined resulting in accurate tire forces and correctly calculated wheel spin rate.
- Realistic and coherent
The underlying concept is a custom vehicle simulation model based on essential physics facts: forces, torques and frictions. This model is easier to understand and simpler to calculate than the commonly used models, yet providing physically accurate and realistic results.
