As an allusion to the car's rocketship styling, the Supersonic design first appeared on a Conrero-tuned Alfa Romeo 1900, which was entered in the 1953 Mille Miglia. Designed by Giovanni Savonuzzi, it was crafted in metal by Ghia, which built eight examples on the 8V Fiat chassis. The Supersonic body was also applied to three Jaguars XK120, an Aston Martin DB2/4 and an even more extreme version was built on a DeSoto Adventurer chassis.
1953 Alfa Romeo Conrero 1900 Ghia Supersonic
Unfortunately, the car didn't cross the finishline in the 1953 Mille Miglia.
The body had been heavily damaged in a crash.
Conrero restored the chassis and rebodied it with a barchetta style body.
