The side-valve six-cylinder 2,968 cc engine delivered a maximum output of 55 PS (40 kW; 54 hp) at 3,500 rpm which translated into a top speed of 100 km/h (62 mph). Power was transmitted via a four-speed manual transmission to the rear wheels which were fixed to a rigid axle suspended from semi-elliptic leaf springs. The braking applied to all four wheels, mechanically controlled using rod linkages.[5]
