Vehicle Physics Pro #

An advanced vehicle simulation kit for Unity 3D providing fully realistic and accurate vehicle physics.

Quick links:

Advanced AAA+ vehicle physics simulation

Built on top of an accurate vehicle dynamics solver providing realistic results for all vehicle types and setups.

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.
