Previous model DKW Junior
DKW F12

DKW F11 and DKW F12 were small cars from the automobile manufacturer Auto Union .

F12

The DKW F12 replaced the DKW Junior in January 1963 . He was an advanced junior de luxe. Technical improvements were ATE Dunlop disc brakes for the front wheels, which were arranged on the transmission output shafts , transverse stabilizers on the front axle and heating with a heat exchanger and fan. The torsion-resistant box-profile frame was retained, but with the wheelbase extended by 75 mm. The roof section has been raised at the rear and provided with an inconspicuous tear-off edge, so that the vehicle height has increased by 50 mm, and the front and rear windows have been enlarged. The radiator grille and taillights have also been enlarged. On request, the F12, like the Junior, was delivered with two-tone paintwork.

The F12 was powered by a three-cylinder two-stroke engine with 889 cm³ displacement , 40 hp, with an automatic fresh oil system that made the car almost 125 km / h fast. The accelerator pedal had a pressure point thanks to a spiral spring , which signaled entry into the full load range and thus contributed to saving fuel. From February 1965, the higher-compression 45 hp variant of the 900 engine was installed, which increased the performance slightly. This version had a gearbox with freewheel as standard, in order to avoid the unpleasant jerking in push mode - when the accelerator is released.

One point of criticism was the maintenance-intensive chassis, which required greasing in 40 places every 10,000 km. With the start of series production of the F12, Auto Union introduced generous guarantee provisions, including a two-year guarantee with no mileage restrictions on the engine, transmission and differential.

The DKW F12 Roadster, a convertible with the 45 hp engine, was presented in September 1963 and produced in a small series by Baur Karosserie- und Fahrzeugbau in Stuttgart from the beginning of 1964 to the beginning of 1965 .

F11

The car presented at the same time as the DKW F102 in August 1963 was a simplified, cheaper version of the DKW F12 with its body, but technically a simple junior de luxe with a 34 hp (25 kW) engine with 796 cm³ displacement. The F11 was offered until June 1965.

The end of the two-stroke car in the Federal Republic of Germany

While the DKW Junior was at times the best-selling small car in the Federal Republic of Germany , Auto Union stopped producing the vehicles after it was taken over by the Volkswagen factory in March 1966, despite the further developed F12 and the new F 102 model . The fault-prone automatic fresh oil system ruined the image of DKW and led to numerous engine damage, including within the warranty period, so that the company was on the verge of bankruptcy. This ended the construction of passenger cars with two-stroke engines in West Germany. The DKW Munga off-road vehicle was built for the German Armed Forces until December 1968 .
