The DKW Type P 4 = 8 which was introduced in 1929 as a successor to the P model.

The car was first shown at the Berlin Motor Show, but then made ​​only in small numbers. The name "4 = 8" was due to the fact that the engine provides a two-stroke per crankshaft revolution per stroke, while a four-stroke engine has only one work cycle for every two crankshaft revolutions.

DKW figured out so that a 4-cylinder two-stroke engine would correspond to the smooth running of an 8-cylinder four-stroke engine.

The vehicle had a four-cylinder two-stroke V-engine with two charge pumps and a capacity of one litre, which developed 25 hp. The car was fitted with a 3-speed transmission with shift lever in the center of the car, power was delivered to the rear wheels. Like its predecessor the 4 = 8, the car had a self-supporting plywood body, which was covered with artificial leather.

The 4=8 was also fitted with two rigid axles with transverse leaf springs like it's predecessor. Only a two-door sedan was offered. The car also had the option of a smaller engine with 0.8 litre displacement which produced 20 hp. However, this caused no reduction in fuel consumption, but only worse performance. In addition, the engine overheated and jumped about slightly even in cold weather. The V 800 was available as a two-door convertible sedan or two-door full convertible. In 1931, the displacement was increased to one litre again and the power of 25 hp also returned. The model was named the DKW 1000 4 V = 8 and was available in sedan, convertible sedan and full convertible, each with two doors, made up until to 1932. 1932 saw the introduction of a longer wheelbase version of the car, which also came with a longer body. Compared to its predecessor, the car is also distinguished by a four-speed gearbox. In October of that year sparked the 1001 DKW special class from this model. The engine delivered more power and the transverse leaf-springs on the rear axle were placed over the axle (floating axle). The body was elegant, but not as enduring as that of its predecessor. The pure wooden construction caused some issues and some even older copies are broken apart in the middle.

1934 was a technically equivalent model with two floating axles out and streamlined body. From January 1935 it's engine was given a second carburetor which helped it to produce 30 hp. In July 1935, there was a completely new engine with a displacement of 1.05 litres and a power output of 32 hp. This new class was produced until 1937. The body styles on offer were a suspended two-door sedan or convertible.

Total productio of all 4 = 8 models is around 24,000 cars over the eleven years, of which about 8,000 cars have an all-steel body.
