Delage D6 classic cars for sale

History of the Delage D6

The Delage D6 was introduced in 1930 as the successor to the Delage Type DM, filling the manufacturer's range with an elegant six-cylinder model. Emerging during challenging economic times, the D6 was positioned as a more restrained offering compared to its lavish predecessors. Early models featured wheelbase options and a 3,045 cc six-cylinder engine with 75 PS, with just 1,160 first-generation units produced by 1933. Over the years, the D6 evolved to echo the technical and stylistic shifts of pre- and post-war France. After WWII, Delage resumed production with the D6 as its sole model under Delahaye ownership, adapting its engines to suit the unreliable post-war fuel situation. The D6 left a lasting legacy in high-end French motoring, often associated with custom bodywork by renowned coachbuilders and success in concours competitions.

Model Series Development

The D6 lineage spans several generations from 1930 to 1953, with significant differences in chassis length, engine displacement, and technology across eras. After the original D6, Delage introduced longer wheelbases and refined six-cylinder engines. During the pre-war years, buyers could select from factory coachwork or commission bespoke bodies from established coachbuilders such as Chapron, which further cemented the D6's reputation for exclusivity. Following WWII, the D6 became Delage’s only model and incorporated Delahaye engines and a reduced compression ratio, addressing the realities of European fuel quality and availability. The D6-70 and D6-75 stand out as notable variants, each bringing upgraded performance and technical improvements.
