M836

Paul Daimler walked out of DMG in 1922 when the supervisory board asked him for a saleable car rather than his eight-cylinder, and Ferdinand Porsche inherited the design office in April 1923 — along with his predecessor's enthusiasm for the blower. The 3.9-liter six he drew for the 15/70/100 PS shared its chassis with the larger 24/100/140 PS and differed only in engine and wheelbase. Its overhead camshaft, driven by a vertical shaft, ran inside a detachable cast-iron head, and iron liners sat in a light-alloy block: far better suited to series manufacture than the welded steel cylinders of the earlier supercharged fours.

Seventy PS on the carburetor, a hundred with the Roots blower engaged. The code is simply a description under the numbering DMG adopted in 1922 — 80 mm bore, 130 mm stroke, six cylinders — and the chassis around it was called W 836 for the same reason. The car reached the public at the Berlin motor show in December 1924, became the Typ 400 in February 1928 when the company switched to displacement-based names, and ran until February 1929, by which point about 1,900 had been built. Its replacement, the eight-cylinder Nürburg 460, made less peak power but more torque, cost far less, and had no supercharger at all.
