History
The DKW F12 replaced the DKW Junior in January 1963. This was basically an evolved junior deluxe. The changes included, among other things, an enlarged front and rear window, a larger grille, heater with heat exchanger and blower and large elongated tail lights. On request, the F12, as well as the junior, offered with two-tone paint.
The F12 fitted with a three-cylinder powered two-stroke engine with 889 cc displacement, 40 hp and automatic oil systems, with internal disc brakes quickly made-equipped cars, some 125 km / h. The chassis and frame concept had been adopted by the Junior and extended by a stabilizer bar on the front axle with type box-type ladder frame the front suspension was independent, wishbones,longitudinal torsion bars, anti-roll bar and telescopic dampers at the rear rigid axle, swinging longitudinal trailing arms, transverse torsion bars, transverse linkage bar and telescopic dampers.
The wheelbase was extended by 75 mm compared to the Junior gave the sedan a distribution of weight of 60% to front axle and 40% to the rear axle. From February 1965, the higher-compression 45-horsepower variant of the 900 engine was installed, which slightly increased the performance. This version had a gearbox with freewheel as standard, which eliminated the unpleasant jerking during coasting.
From early 1964 to early 1965 in a small series of Baur body and vehicle construction in Stuttgart. The DKW F12 Roadster, a convertible with the 45-horsepower engine, was introduced and produced.
