1911 Delaunay Belleville 25 hp HB6 Landaulette Coachwork By Rothschild

At the beginning of the century, the Delaunay-Belleville HB6 was one of the most desirable and expensive French cars that rivaled Daimler and Rolls-Royce. Emphasis during construction was placed on fine materials and craftsmanship which attracted the pillars of society. Customers to Delaunay-Belleville included King Alphonso XIII of Spain, King George I of Greece and Czar Nicholas II of Russia.

S.A. des Automobiles Delaunay-Belleville was formed by Marius Barbarou and Louis Delaunay in 1903. Delaunay married into the Belleville family who owned the boiler making company of St. Denis. This relationship was reflected on the styling of Delaunay-Belleville cars with the engine surrounds on many examples capturing the character of the boiler company.

Marius Barbarou was responsible for much of the styling and design of the cars. He had previous experience working for Clement, Lorraine-Dietrich and Benz and was directly responsible for the 1904 Paris show car. He helped adopt the Belleville patented system of lubrication to internal combustion engines. This systems was one of the first to use a pressurized system of pumps and oil ways instead of the common drip system used during the period.

The 25HP type HB6 model included a 6-cylinder engine having two blocks of three cylinders. This was attached to a four speed manual transmission and used the Belleville patented system of lubrication.
