1904 de Dion-Bouton Model AD Gallery

In the summer of 1904 de Dion-Bouton launched their first four-cylinder car and called it the Model AD. Besides this engine, the AD incorporated several new components that distinguished the model from its predecessors. These included a pressed-steel chassis and a simple dry-plate clutch that acted on the flywheel instead of each separate gear.
