Vincenzo Lancia's final great masterpiece was the Lancia Aprilia which went into production early in 1937, a new compact car, seating five in comfort and combining speed with economy. The aerodynamic saloon was of unitary construction with minimal (for the period) drag factor, sliding pillar front suspension, trailing arm rear suspension incorporating a transverse leaf spring, and powered by a forward mounted 1,352cc V4 engine. The all-new engine featured hemispherical combustion chambers, aluminium cylinder block and Duralumin conrods and developed some 47.8bhp. Designer Falchetto was responsible for the styling, with considerable influence from Pininfarina at Corso Trapani.
