1910 was a productive year for Delage. This is thanks to the introduction of the 4-cylinder 12 HP type AB and 4-cylinder 10 HP type AC models – both powered by Ballot engines. The AB model, which was to be produced in nine series, was powered by the Ballot 4F engine for the first three, and the Ballot 4FM engine for the fourth through to the ninth series. The eighth series AB 4 was distinguished by its refined mechanics, 4-cylinder engine of 2.1 litres, and 12 HP. All this contributed to the car’s lightness and purity of body lines. The Museum bought it for 6,000 francs from a Lyon dealer in 1963 “complete, running, and in excellent condition”, as well as featuring a long list of accessories.
