1953 Fiat 8V Supersonic (Ghia coachwork)

106.000053roadItaly
Engine
OHV light-alloy V8, ~135 bhp (tuned output)
Colour
Medium metallic blue ('blu medio metallizato')

The Fiat 8V chassis 000053 is one of only 14 Supersonic-bodied examples constructed by Carrozzeria Ghia on a Fiat 8V platform, wearing coachwork designed by Giovanni Savonuzzi in a distinctive blue metallic over terra cotta leather colour combination unique among the Supersonics. Dispatched from the Fiat factory in July 1953, the car passed through a short chain of Italian owners before spending over three decades in underground storage, emerging as an essentially original survivor. A meticulous body, mechanical, and interior restoration was completed in the early 2010s by Italian specialists.
