De Dion-Bouton 8 HP Classic Car for Sale

Introduction and History of the De Dion-Bouton 8 HP

De Dion-Bouton, a pivotal name in automotive history, launched the 8 HP model during the transformative years of 1907 and 1908. As one of the French brand’s most representative vehicles from the Edwardian era, the 8 HP illustrates the shift from horseless carriages to purpose-built automobiles. Equipped with a robust single-cylinder engine and advanced chassis engineering for its era, the 8 HP was widely regarded by period motoring enthusiasts and collectors today for its technical quality and reliable construction.

Model History

The De Dion-Bouton 8 HP belongs to the brand’s celebrated range of medium-powered vehicles, following a series of smaller 'voiturettes' that established the company’s reputation in the 1890s and early 1900s. The Model BG was succeeded by larger, more powerful multi-cylinder models as the company advanced technologically, responding to increasing demands for greater performance and passenger comfort. The 8 HP thus marked an evolutionary step between the brand's pioneering singles and their later, more elaborate tourers.

Highlights of the De Dion-Bouton 8 HP

Standing out for its period-correct engineering, the 8 HP combines a 942 cc single-cylinder power unit delivering 8 horsepower at 1,400 rpm. Notable features include a 3-speed manual gearbox, halbelliptic leaf spring suspension front and rear, and drum brakes on the rear wheels. With its right-hand steering layout and rigid chassis, it exemplifies the design logic of early 20th-century motoring. Its historical relevance is underlined by its importance among collectors and pre-war motoring historians.

Engine and Performance, Transmission and Handling

The 942 cc single-cylinder engine is noted for its straightforward mechanical construction, producing 8 horsepower—enough to propel the light chassis of the 8 HP with reliability for its period. The 3-speed manual transmission, while requiring familiarity, offers direct engagement through a robust gearbox.
