MERCEDES-BENZ VITO • VIANO • V-CLASS
Understanding the Evolution, Generations, Mechanical
Architecture and Differences Between Commercial Vans
and Premium Passenger Transportation
1. Introduction: Mercedes-Benz Van Family
The Mercedes-Benz Vito, Viano, and V-Class belong to the same broader Mercedes-Benz van family. However, their identities differ according to their intended applications, equipment levels, and passenger or commercial transportation requirements.
The Vito primarily represents the commercial and utility-oriented configuration. The Viano represents the premium passenger configuration associated with the W639 generation, while the V-Class represents the premium passenger identity used in W638 and revived with W447.
Fundamental concept:
These vehicles are not simply three unrelated Mercedes-Benz
models. They represent different interpretations of a
shared van-family philosophy, with generation-specific
engineering and equipment differences.
