IXO LMC100; Lorraine-Dietrich B3-6; 1925 24h Le Mans 3rd; Brisson & Stalter; RN4

In 1919, new technical director Marius Barbarou (late of Delaunay-Belleville) introduced a new model in two wheelbases, the A1-6 and B2-6, joined three years later by the B3-6, with either short or long wheelbase. All fell in the 15 CV fiscal horsepower category, sharing the 3,445 cc (210.2 cu in) six cylinder engine, which had overhead valves, hemispherical head, aluminium pistons, and four-bearing crankshaft.

The performance was such in 1923, three tourers "put up a passable showing" at the first 24 Hours of Le Mans, leading to the creation for 1924 of the 15 Sport, with twin carburetion, larger valves, and Dewandre-Reprusseau servo-assisted four-wheel brakes (at a time when four-wheel brakes of any kind were a rarity); they ran second and third, and were comparable to the 3 litre Bentleys. The 15 CV Sport did better in 1925, winning Le Mans, followed home by a sister in third, while in 1926, Bloch and Rossignol won at an average 106 km/h (66 mph), leading a 1-2-3 sweep by Lorraines. Lorraine-Dietrich thus became the first marque to win Le Mans twice and the first to win in two consecutive years.
