The Mercedes-Benz E-Class is a range of executive-size cars manufactured by Mercedes-Benz in various engine and body configurations. The E initially stood for Einspritzung, (German for fuel injection); a new feature in volume production vehicles at the time that the E-Class first appeared, with the E as a suffix to the engine nomenclature (e.g. 220E) in the 1950s. It was not until the launch of the facelifted W124 that the E was used as a prefix (i.e. E220) and the model referred to officially as the E-Class (or E-Klasse). Due the E-Class' size and durability the cars also frequently serve as taxis in European countries, Mercedes-Benz offers "taxi specification", as well as other special purpose vehicles (e.g. police or ambulance) from the factory
