25 Concept Cars We Wish Were Mainstream

1935 Bugatti Type 57S Competition Coupe Aerolithe

One of the oldest “concept cars” is also from Bugatti, the Bugatti Type 57S Competition Coupe Aerolithe from 1935. It was made from lightweight magnesium and only appeared a handful of times, during the Earl’s Court Motor Show in the United Kingdom in 1935. It only went on one road test, a full year later. After an appearance during the 1936 London Motor Show, it disappeared.

The Aerolithe never reached production. Instead, the metal was probably used to help the military during World War II. This model represented a huge jump forward in engineering, styling, and aerodynamics, along with the first magnesium bodywork of the time.
