One of the first cars to be built using a wind tunnel, the Lancia Aprilia had a record drag coefficient of 0.47 and was marketed as the “berlinetta aerodinamica”. The year 1937 marked the first Aprilia coming out of the factory doors, but also the year the founder Vincenzo Lancia died. The Aprilia was to be the last ever model he designed, with rear suicide doors and no B-pillar. The first generation was fitted with a 47hp V4 engine which sold in just over 10,000 units. A second run of the Aprilia started in 1945, with the model being almost identical to the original one, but with a slightly better engine.
