MAN Lion's City GXL A43 — 20.5m 4-Axle BRT Bus Mod

MAN Lion's City GXL A43 — 20.5m 4-Axle Articulated High-Capacity Bus Mod for Proton Bus Simulator

The MAN Lion's City GXL (A43) is the 20.5-meter 4-axle articulated variant of MAN's Lion's City urban family — the largest in the lineup, sister to the A21 standard rigid, A23 GL articulated, and A26 long rigid. This Proton Bus Simulator mod captures the rear-steering quad-axle architecture that makes the A43 maneuverable despite its extreme length, the defining technical feature that allows operators like Tehran's BRT and Istanbul's Metrobüs to run this XXL platform on high-density urban corridors.

Highlights and Features

• Drive the 20.5-meter MAN Lion's City GXL, the largest 4-axle articulated variant in MAN's Lion's City urban family.
• Operate quad-axle physics with rear-axle steering that allows the A43 to negotiate urban corners despite its extreme length.
• Deploy on BRT and high-capacity urban corridors mirroring Tehran's BRT and Istanbul's Metrobüs real-world service.
• Run smoothly on Android with mobile-tuned textures that keep frame rates stable on extended-length bus geometry.

Compatibility and Technical Details

About the Real MAN Lion's City GXL (A43)

The MAN A43 platform was introduced in 2007 under the "CapaCity" name as MAN's flagship 4-axle articulated urban bus, with production at MAN's plant in Starachowice, Poland. The chassis was rebadged "Lion's City GXL" when the wider Lion's City family was refreshed in the mid-2010s, but the underlying 20.5-meter 4-axle architecture with rear-axle steering remained unchanged. The A43 is one of the largest serial-production city buses in the world — designed for Bus Rapid Transit (BRT) systems and the densest urban corridors where conventional 18-meter articulated buses cannot meet passenger throughput demand. The largest A43 fleet operates Tehran's BRT in Iran, with significant deployments also on Istanbul's Metrobüs network in Turkey, Hamburg's Hochbahn in Germany, Malmö in Sweden, and several Saudi cities. Within MAN's Lion's City family, the A43 sits as the high-capacity flagship alongside the A21 standard rigid (12m), A26 long rigid (15m, 3-axle), and A23 GL articulated (18m).
