Instrumentation included a centrally mounted speedometer, the fuel level and the oil pressure.
A third dial directly below the driver's sight line was a clock, unusually on this size of car.
The three floor pedals followed the pattern still 'conventional' for a manual transmission car (clutch, brake, gas) but  to the left of the clutch pedal was a small foot-operated dipper switch for the headlights.
Control knobs lined up along the base of the fascia included a hand throttle.

Early Italian images of Ardea interiors confirm that Lancias of the period were still right hand drive, a position elsewhere taken to imply driving on the left side of the road.
However, right-hand drive is practical even where drivers drive on the right-hand side of the road as it allows a better view of the edge of the road, which is useful when driving on rough roads in mountainous districts.
   This did mean that drivers of cars with centrally located floor mounted gear shifts, such as the Ardea, needed to learn how to shift with the left hand.
During the 1920s Italian leader Benito Mussolini required all Italian drivers to drive on the right, but Lancia would continue, through the 1950s, to supply right hand drive cars in areas viewed by other automakers as left hand drive markets.
