Concept Car of the Week: Alfa Romeo BAT 7

This week sees the Concept of the Week title go to Alfa Romeo and Bertone for their collaboration on the Alfa Romeo BAT 7, the second addition to the BAT series that began in 1953 and finished in 1955. First seen at the 1954 Turin motor show, this wildly futuristic ‘dream' car came about after Alfa Romeo contacted Giuseppe "Nuccio" Bertone of the Bertone carrozeria to commission three concepts with the lowest possible drag coefficient. The cars were named BAT for "Berlinetta Aerodinamica Tecnica." Built upon the Alfa Romeo 1900 chassis, the BAT cars featured large rear bumpers and curved fins, and the concepts achieved a drag coefficient of just 0.19 - an impressive result.
