1949 Delahaye 178 Cabriolet by Chapron

820034roadFrance
Engine
Standard 178 engine, same displacement as the late-1930s Delahaye V-12
Colour
Gray with cream accents on body and fenders (two-tone)

One of only seven surviving Delahaye 178s and the sole remaining cabriolet bodied on the 178 chassis by Henri Chapron, this left-hand-drive example was completed on 10 August 1949 with engine number 820034 and optional Rudge wheels. Chapron's characteristically refined proportions are distinguished here by louvered bonnet, a grille-integrated front bumper, and an unusual split vee'd windscreen. Restored by RM Auto Restoration in the mid-1990s, it won Best in Show – European at the 2000 Meadowbrook Concours d'Elegance, and later passed to automotive publishing magnate Robert E. Petersen.

Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
