Only 4,076 were constructed in its 11-year run, with the majority built in its debut year before the Great Depression took strong hold.
Development proceeded in great secrecy over the next few years; a number of prototype cars were built and tested as the new engine was developed, while at the same time Cadillac chief Larry Fisher and GM's stylist Harley Earl toured Europe in search of inspiration from Europe's finest coachbuilders.
One Cadillac dealer in England, namely Lendrum & Hartman, ordered at least two such chassis in even rarer right hand drive (RHD) configuration and had Vanden Plas (Belgium) build first an elegant limousine-landaulet (engine #702297), then a sports sedan with unusual cycle fenders and retractable step plates in lieu of running boards (engine #702298, which was successfully shown in various Concours d'Elegance events in Europe before being bought by the young Nawab of Bahawalpur); both these cars have survived.
A third RHD chassis was ordered by the Indian Maharaja of Orchha (Bhopal) and sent to Farina in Italy, in July 1931, for a boat tail body (engine between #703136 and #703152).
Despite the bad timing and high retail price, and although sales would later drop off considerably, the launch "exceeded Cadillac’s fondest aspirations.
Beginning in June 1930, five new V-16s participated in a promotional tour of major European cities including Paris, Antwerp, Brussels, Amsterdam, Utrecht, Copenhagen, Stockholm, Berlin, Cologne, Dresden, Frankfurt, Hamburg, Munich, Nuremberg, Vienna (where they won prizes), Berne, Geneva, Lausanne, Zürich, Madrid, San Sebastian, La Baule and Angers.
On the return journey from Spain, the V16 caravan stopped also in the town of Cadillac, in south-western France, although that city bears no relationship to the marque, other than its name.
With a wheelbase of 154.0 inches (3,912 mm) and a curb weight of up to 6,600 pounds (3,000 kg) these are perhaps the largest standard production cars ever produced in the United States.
This chassis was delivered to Lausanne, Switzerland, to be bodied by Carrosserie Willy Hartmann per an order by local resident Philippe Barraud, a wealthy paper mill heir and playboy of the 1930s.
Stretching 22 feet in length, the car was designed in the sweeping cabriolet style of the Delahaye built by Figoni & Falaschi for the 1936 Paris Auto Salon.
In 2003, Cadillac created a concept car called the Sixteen, which used a 13.6 litre V-16 engine that developed 1,000 bhp (746 kW; 1,014 PS).
Even though it used the current "A&S" (Art & Science) style of design that is Cadillac's stylistic hallmark, it shared many small details from the classic V-16.
