Production1912
Recorded originFrance
ClassHistoric passenger, commercial and competition automobile
Power12 hp
Smallest securely exhibited member of the 1912 Darracq-Henriod 'Valveless' range. The four-seat torpedo and rotary-distributor principle are period documented, but later type codes and capacities conflict. It is not backfilled from the larger 2,614 cc 16 HP car, and the Henriod mechanism's commercial failure is described without pretending every 1912 Darracq used it.
