the name being now conventionally based on the car's approximate engine displacement. The successor model, already in production in 1957, also benefited from this less challenging nomenclature. The bodies The F91 was presented as a two-door saloon with front opening doors which presumably facilitated access. A ‘pillarless’ coupe version, first seen in 1953, was produced from 1954, as well as a cabriolet, bodied by Osnabrück coach builders Karmann. In addition there was a three-door estate version, called the ‘Universal’, which continued to be offered unchanged until 1956. Modifications came progressively. The coupe version had been launched with a ‘panoramic’ three piece wrap around back window, and in the back end of 1954 a similar wrap-around back window appeared on the two-door saloon. Advertising highlighted such features as a fuel gauge and an interior light that could be set to come on automatically when the door was opened. 1955 saw the launch of the F93 version (for the 1956 model year), also known as the Big DKW 3=6. This shared the wheel-base of the F91, but was slightly longer, wider and taller. The track was also increased by . In place of horizontal metal slats, the new model featured an oval shaped front grill containing five horizontal metal coloured slats. The oval grill was modified again in 1957 when the slats were replaced by a chrome coloured grid design. Inside there were improvements to the instrumentation and the heating, as well as a modest increase in power to 40 bhp. The DKW Monza which appeared in 1956 was essentially a DKW F93 under its (light-weight plastic) skin. In 1956, with the introduction of the F94 version of the car, a four-door version finally became available. The four-door saloon's wheel-base was extended by over that of the two door: advertising continued to emphasize the DKW's class leading interior spaciousness. 1956 was also the year when the F91 ‘Universal’ estate version (the F91S) was replaced by the F94U Universal: it now incorporated many of features introduced two years earlier on the saloons. The F94 four door saloon and F94 Universal shared the same chassis. DKW in Brazil Auto Union cars were also very popular in South America, where a number of special types based on the DKW 3=6 were manufactured in Brazil under licence by VEMAG from 1956 to 1967. Models sold were the DKW Belcar sedan, the Vemaguet station wagon, and the
