Caio's Enduring Presence in the Simulator
Caio's history as a Brazilian bus body builder is reflected in the variety of models available for Proton Bus Simulator. Building upon the foundation of `urban bus` manufacturing that emerged in Brazil, Caio has consistently adapted its designs to meet evolving transport needs. The mods in the catalog represent a portion of this legacy, showcasing vehicles that have served countless passengers.

High-Capacity and BRT System Contributions
Caio has been a significant contributor to high-capacity public transport solutions in Brazil, particularly for `BRT (Bus Rapid Transit)` systems. The mod catalog highlights this focus, with `SingleDeckerBRT` models representing 42.9% of the available Caio mods, making it the dominant body style. These specialized vehicles are designed for efficient passenger flow and integration into dedicated bus corridors.
