Maybach 12 Pullman-Cabriolet (Karosserie Papler) 1929/30.

Due to the immense popularity of the airships LZ 127 "Graf Zeppelin" powered by Maybach twelve-cylinder engines the company decided to introduce a big car with a similar engine. In 1929, the Maybach 12 appeared. It has the first V12 engine used in an automobile. Dry weight of the engine is only 510 kg thanks to the wide use of aluminium. The crankcase is a light metal cast block with dry cast iron cylinder liners. The engine heads, the oil pan and the pistons are also made of light metal. The short-stroke engine has a maximum piston speed of only 10 m / sec. The car, instead of the previous planetary gear has a regular three-speed gearbox with middle shift lever and a semi-automatic overdrive.
The new DS 7 and DS 8 has a vacuum actuated air servo for the Bosch-Dewandre mechanical brakes and a five-speed gearbox ("double speed") with vacuum-operated preselector.
