A Concept of a Modern Low-Floor Bus for Scheduled Services-Philosophy and Realization
Published June 05, 1997 by Verlag Des Verein Deutscher Ingenieure GmbH in Germany
The CITARO's outward appearance differs in principle from previous city buses. Particularly noteworthy are the following features: The front window which extends far down and forms a formal unit with the sign box integrated above ensures optimal visibility for the driver. The lateral windows on the left and right sides characterize the front part of the vehicle. The continuous side windows extend to the roof profile and make the vehicle appear very transparent and inviting. All displays are integrated and glass-enclosed.
The design of the vehicle module was based on the following substantial premises: increased safety; better comfort; greater reliability; modularity for the complete production series; improved low platform design without the loss of seating space; reduction in production complexity; reduction of materials costs; doubling service intervals; reduction of life cycle costs; realization of two diesel engine production series to ensure the most efficient use of energy for all applications.
Conditions for realizing the Euro III having the respective engines available without any modifications to the engine periphery. Establishing the conditions for realizing, without compromise, all currently expected alternative drive mechanisms while maintaining the modular concept. Basic design of a new driver work station to be included in the standard vehicle equipment. Improved turning circle. Equal wheel base, and thus largely the same components, in the front car of the articulated bus as in the two-axle vehicle. Realization of a heating/ventilation/air conditioning modular system meeting maximum requirements. Full diagnostics ability.
The uncompromising realization of so many conditions, however, means that there will be nothing left of the current vehicle modular system, even with respect to parts, with the exception of a few basic measurements and arrangements. The CITARO is a completely new vehicle
