Model with a 6-cylinder in-line engine of 2,867 cm3 and 77 hp introduced in 1938. This high-end car uses an 11B engine extended by two cylinders (dimensions 78x100) and an 11B body. Despite its name, this car is a 16 HP tax car. The common name 15 HP is therefore erroneous but widespread, the official name being 15-Six.
The 15-6 quickly became the "queen of the road" because of its high performance (135 km/h) and excellent road holding. The body is available in sedan, extended "interior drive" and wagon versions. Only five factory convertibles were built.
Put back into production in 1946, the 15-6 received a modified right-hand drive engine in 1947 (as did all four-cylinder cars since 1934) and became the 15-6 D. The previous models are retroactively called 15-6 G.
