DKW 3=6
The DKW 3=6 was a compact front-wheel drive saloon manufactured by "Auto Union GmbH". The car was launched at the Frankfurt Motor Show in March 1953 and sold until 1959. It was also named as the DKW Sonderklasse and, following the factory project number, as the DKW F91. From 1958, by which year the car's successor was already being sold and the earlier version had therefore become, in essence, a ‘run-out’ model, it was badged more simply as the DKW 900. Apart from complications involving its naming, the 3=6's notable features included its two -stroke engine and front-wheel drive layout along with the sure-footed handling that resulted. In a market segment increasingly dominated by the Volkswagen Beetle, the Auto Union contender also boasted class leading interior space, especially after the arrival of the four-door version, which featured a modestly extended wheelbase. The DKW 3=6 in due course replaced the DKW F89 / Meisterklasse, although the "Meisterklasse" remained in production until April 1954. In its turn, the 3=6 was succeeded by the more powerful Auto Union 1000, offered already from 1957. Many names. DKW was one of four companies that had come together  in 1932 to form the Auto Union based in Zwickau. The company was effectively refounded in West Germany in 1949, following the loss to the Soviets of its Zwickau assets. Three of the four businesses that had constituted Auto Union before the war seemed unlikely ever to reappear on either side of the Iron Curtain, but starting in 1949 the DKW name was used for the F89 assembled by Auto Union in the west: this was the model replaced by the 3=6. It was perhaps in recognition that any perceived marketing advantages available from the unconventional namings had been exhausted , that from 1958 the car was sold simply as the DKW 900, 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 June 1957, by which time saloon buyers had been offered the F93, an upgraded version, for two years. 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, also known as the Grosse 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. The DKW Monza which appeared in 1956 was essentially a DKW F93/F94 under its (light-weight plastic) skin. In 1957, 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. 1957 was also the year when the F91 ‘Universal’ estate version was upgraded to an F94: it now incorporated many of features introduced two years earlier on the saloons. 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 Fissore, a two-door coupe with a smooth designed body and elegant appointments, which resembled in general terms the DKW F102. The F94 line made by DKW-Vemag was equipped with doors hinged at the front (from 1964) and four headlights (in 1967). Altogether about 109,343 cars were built in Brazil. Technical. The 896 cc three cylinder engine provided at launch a claimed . Following the company's pioneering work in the 1930s, the car had a front-wheel drive configuration which meant there was no bulky driveshaft running through the passenger  cabin. The water cooled engine was installed longitudinally above the front wheels - the first appearance of the longitudinal "overhung" engine layout which DKW's successor - Audi - still uses to the present day, but the radiator was located not ahead of the engine but between the engine and the passenger cabin. The gearbox, controlled by a column mounted lever, was a three speed manual system coupled with a free-wheel device: in Autumn 1953 a four speed box was offered as an option. 1957 saw a further transmission advance with the availability of a Saxomat automatic centrifugal clutch on the DKW . The F93 version launched in 1955 now boasted power output increased to . That increased further to in 1956. The F93 also incorporated a strengthened chassis and improvements to the suspension and braking system.
