Why it matters

The Aerlux is the Touring Superleggera coupé on the short-wheelbase 6C 2500 Super Sport chassis fitted with a Plexiglas sunroof, which gave it its name. Alfa Romeo records only 19 in this version, out of fewer than 500 6C 2500 SS.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The Heritage story follows one Aerlux, bought new in Milan in November 1949 and sold in 1951 to an Italian-Mexican businessman who entered it in the Carrera Panamericana. Its remains were recovered in 2013 and the car was restored and its history reconstructed from the original documents.
