The Types H J, L and M were four cars mid to large-size cars produced from 1908 to 1910 by the French automaker Delage.
The French company opened a new market with these four models. One of the cars was in the mid and medium-high ranges, and untl then the car with the highest category was the Type G with its 1.2-liter engine, which was only considered medium-low.
These cars, which were introduced around the same time as the contemporary Type E, F and G, were developed with different engines over just a two-year time frame.
The first of the four to be introduced was the Type H, equipped with a new engine derived from a 1767cc four-cylinder De Dion-Bouton capable of delivering up to 15 bhp of output. The production of the Type H was interrupted at the end of the same year to make room in 1909 for the Type J, a car that came in two engine variants: the lowest being identical to that of the Type H, and the highest being a new 2121cc four-cylinder engine capable of delivering about 18 bhp of maximum power.
During the same year, Delage introduced the other two cars of the series: the Type L and Type M. The first was available with two engines: a four-cylinder engine with 1328 or 1460cc displacement, respectively capable of delivering 12.5 and 14 hp of maximum power. At the end of 1909, however, production of the Type L ceased.
The Type M, however, was produced until 1910, and was available in five engine variants: the first two were identical to those equipped in the Type L, while the others were all four-cylinder engines with displacements of 1505, 1593 and 1847 cc. These were the first three engines entirely designed and manufactured by Delage.
