The Lancia Appia is a passenger car introduced in 1953 by Italian car manufacturer Lancia as a replacement for the Ardea, and which remained in production for ten years. The Appia was the last in a long line of Lancia production cars dating back to the Lancia Lambda to use sliding pillar front suspension. All three series produced had a 1089cc Lancia V4 engine.
