MAN Lion's City A21 V3 – Diesel & CNG NL263/273 Bus Mod

Highlights and Features

• Drive the 12-meter MAN Lion's City A21, the standard 2-axle rigid variant of MAN's Lion's City urban family (sister to the articulated A23 GL and long-rigid A26)
• Choose between Diesel (D2066, 11-litre 6-cylinder) and CNG (E2876, 12.4-litre 6-cylinder) engine variants in one package — two distinct urban driving experiences
• Operate the chassis designated NL263 (diesel) or NL273 (CNG), the two fuel-type variants in MAN's Lion's City lineup
• Take advantage of the V3 Edition's refined dashboard differentiation between fuel types and improved textures over earlier releases
• Deploy on European urban maps where the A21 fits its real-world Berlin BVG, Munich MVG, Lisbon Carris or Madrid EMT operator context
• Benefit from texture optimization that keeps frame rates stable on Android builds of Proton Bus Simulator while preserving cabin and exterior detail

About the Real MAN Lion's City A21

The MAN Lion's City A21 is the 12-meter 2-axle rigid variant of MAN's Lion's City urban bus family, introduced in 2004 by MAN Truck & Bus as the successor to the SL II generation. The A21 sits as the standard configuration in the family alongside the A23 GL articulated (18m), A26 long rigid (15m, 3-axle) and A37 articulated variants. Built across MAN's bus plants in Salzgitter (Germany), Starachowice (Poland), Akyazı (Turkey) and Rawang (Malaysia), the A21 is the most widely deployed Lion's City variant in European urban transit — operated by Berlin's BVG, Munich's MVG, Lisbon's Carris, Madrid's EMT and many other major municipal carriers. The NL263 and NL273 chassis designations identify the diesel and CNG engine variants respectively, with the D2066 11-litre 6-cylinder diesel and the E2876 12.4-litre 6-cylinder compressed-natural-gas engine powering the two fuel-type options.
