Mercedes DF 100 aeroengine goes into large-scale production

The Mercedes DF 100 (D I) aeroengine goes into large-scale production at DMG. The 100 hp / 74 kW six-cylinder is an advanced version of the DF 80 used in the 1913 competition for the Imperial Prize. Production of the D II with 120 hp / 88 kW and the D III with 160 hp / 118 kW also starts by the end of the year. The two six-cylinders derived from the DF 100 were designed by DMG for the second Imperial Prize, which is cancelled because of the outbreak of war.
