iCars is a vehicle animation and traffic simulation add-on that includes a library of 18 rigged vehicles. Each vehicle is provided in both low-poly and high-poly variants and utilizes a customizable material system featuring realistic reflections, metallic flakes, clear coats, and glass shaders.

The toolset provides four distinct animation modes: ghost control, curve control, auto drift, and free drive. It generates traffic systems with built-in support for traffic lights, roundabouts, highways, and city streets. The add-on includes a ghost preview system for visualizing future animation frames and features built-in camera controls that can automatically follow vehicles along their paths. It also offers direct integration with the iCity environment add-on.
