Recorded originFrance
ClassHistoric passenger, commercial and competition automobile
Power20 hp
Largest fully period-specified Darracq-Henriod passenger model. It used thermosiphon cooling, a dash fuel tank and the proprietary rotary distributor. A modern P12/4.4-litre attribution conflicts with the contemporary 95 x 140 mm dimensions and is excluded. Exhibition chassis and completed touring car are configurations of the same 3,969 cc model.
