iCars is a Blender add-on from iCity built around realistic traffic simulations, car rigging, and crash physics. The rigs are modular, and setup is designed to be fast. Rendering runs through both Cycles and Eevee.
The add-on is offered across several packs: a Vehicles Pack, an Animation Pack, and a Traffic Pack, alongside a Free Pack. Documentation is included, and a demo video is available. It is released under the GPL license and targets Blender 5.0.
Within the superhive library, iCars covers the range from rigged vehicles to physics-driven crashes and moving traffic, so the same set of tools handles both animation and simulation work. A Free Pack is listed here at no cost, alongside the other packs. A 30-day guarantee accompanies the product, and the included documentation supports getting set up.
