Mercedes-Benz Cito O520 — Diesel-Electric Midibus Mod

Mercedes-Benz Cito O520 — 9.6m Diesel-Electric Midibus Mod for Proton Bus Simulator

The Mercedes-Benz Cito O520 is the diesel-electric hybrid midibus produced by EvoBus at the Mannheim plant in Germany from 1998 to 2003 — one of the first serial-hybrid city buses to reach European fleets and instantly recognizable by its constant-RPM turbine-like engine note. This Proton Bus Simulator mod brings the 9.6-meter Cito into PBSU with the unconventional gearbox-free drive feel and the unmistakable sound profile that distinguished the real bus from its conventional contemporaries.

Highlights and Features

• Drive a rare serial-hybrid diesel-electric midibus where the diesel runs a generator and electric motors drive the rear wheels.
• Experience the gearbox-free continuous-delivery acceleration that gives the Cito its smooth feel unlike conventional bus mods.
• Operate the compact 9.6-meter midibus configured for tight European urban routes and narrow inner-city corridors.
• Hear the recognizable turbine-like whine that comes from the constant-speed diesel generator driving the electric motor.

About the Real Mercedes-Benz Cito O520

The Mercedes-Benz Cito O520 is a low-floor midibus produced by Mercedes-Benz subsidiary EvoBus at the Mannheim plant in Germany from 1998 to 2003. It was among the first serial-production diesel-electric hybrid city buses in Europe — a small diesel engine powered a generator that fed electric motors at the rear wheels, eliminating the gearbox and producing the constant-speed engine note that became the Cito's acoustic signature. Sold in 8.0-meter, 9.6-meter and 10.6-meter variants, only around 700 units were built before Mercedes-Benz discontinued the Cito and shifted the small-bus role to the conventional-drive Citaro K.
