Caio Millennium I O-400UPA — SP Passa Rápido BRT Bus Mod

Caio Millennium I O-400UPA — São Paulo Passa Rápido Era BRT Corridor Bus Mod for Proton Bus Simulator

The Caio Millennium I on Mercedes-Benz O-400UPA chassis is the first-generation Caio Millennium body family deployed on São Paulo's Passa Rápido BRT corridor service during the early-2000s Marta Suplicy administration. This Proton Bus Simulator mod brings the original Millennium styling and the roaring MB O-400UPA floor-engine driveline into PBSU, with custom skins, wheelchair-lift accessibility, and the period-correct paulistano urban-corridor configuration that anchored the dedicated bus-lane service in the years before the modern Move and Expresso Tiradentes corridors.

Compatibility and Technical Details

About the Caio Millennium and São Paulo Passa Rápido

Caio is a Brazilian coachbuilder headquartered in Botucatu, São Paulo state, and one of the country's main urban-bus body manufacturers. The Caio Millennium is the family of urban bus bodies that anchored Brazilian municipal fleets through the late 1990s and 2000s, with the first-generation Millennium I representing the original styling before the later Millennium II and IV facelifts updated the front fascia and trim across the family's production run. The Mercedes-Benz O-400UPA is the floor-engine urban chassis from Mercedes-Benz do Brasil, with the UPA designation marking the urban configuration sized for municipal corridor service. São Paulo's Passa Rápido corridor system was the dedicated bus-lane service implemented during the early-2000s Marta Suplicy administration (2001-2004), preceding the modern Expresso Tiradentes biarticulated corridor and the Move BRT system that defined later paulistano mass-transit infrastructure.
