The Pontiac Club de Mer was a purpose-built, concept car that was unveiled at the General Motors Motorama in 1956 to celebrate GM's commitment to futuristic design. The brainchild of GM designer Paul Gillian, the de Mer was a two door sport roadster that incorporated innovative breakthrough styling like a sleek, low-profile body encasing a large powerplant, a design trend used widely in LSR (land speed record) trials at Bonneville Salt Flats in Utah during the 1950s. One Club de Mer prototype was constructed and unveiled, along with another ¼-scale model, in Miami, Florida. As per GM's "kill order"[2], it was scrapped in 1958. Only the 1/4-scale model exists today, owned by noted car collector Ron Pratt who purchased it at the 2007 Barrett Jackson Classic Car Auction for $75,000

Design[edit | edit source]

The design of the de Mer drew its visual impetus from contemporary aircraft construction of its day, employing a stainless steel monocoque, individual wind screens similar to those on the 1955 Lincoln Futura (later TV's Batmobile), aerodynamically fashioned facia that flowed down from the hood skin to cover most of the grill, concealed headlights, and a single rear-deck dorsal fin. Also featured were twin "silver-streaks"[3] that flowed into low-profile hood scoops, a carry-over from Pontiac's Bonneville Special two years prior. The overall styling of the body was a smooth, non-undulating profile, similar to an American supersonic jet fighter, with virtually no protrusions or recesses of any kind save for the out-vents on the leading edge of both doors, and the fin. The vehicle had no bumpers, a common feature on most concepts, and the door handles were quite small. On a human scale, its most alarming feature was that it had a very low profile at just under 39 inches.


The interior styling in the de mer had a barebones functionality to it, more in keeping with its speed trial “airs” than the flashier production vehicles available in showrooms at the time. Instruments were low key, with triangularly configured gauges mounted well behind a three spoke, GT-style steering wheel, around the steering column. The speedometer was positioned on top, and a smaller gauge on either side, each enclosed in its own pod. The interior was finished in red, while passengers gained entry through conventional doors.

Power plant[edit | edit source]

Under the hood lay Pontiac’s brand new wonder engine, the 287 OHV V-8 which was unveiled the year prior. Called the Strato Streak, it was GM's most powerful engine by 1955 and ushered in Pontiac’s high-performance image with the Bonneville, Grand Prix and GTO. This high-output power plant was modified with a high-lift cam and fitted with two four-barrel carburetors to coax power up to a mighty 300 bhp. The rear wheels were driven by a rear mounted transaxle, used later in Pontiac's new compact, the 1961 Tempest, on a DiDion Type rigid rear axle with independent suspension.

Trivia[edit | edit source]

  • "Concept" was not a term used in the 1950s but instead "experimental car".
  • The individual bubble windscreens were an innovation carried over to the 1956 and 57 Corvette racing car.
  • The model kit maker Revell made a 1/25 scale Club de Mer that actually came with 1950s-clad driver and passenger.
This article or section contains information about a concept automobile.

It is likely to contain information of a speculative nature, but such speculation is usually sourced from the automotive news media, the automaker's media press releases, or other news sources. Concept cars, or similar evolutionary vehicles based on them, may never see production. The content and specifications for those selected for continuation may change significantly as the concept evolves, or as production nears if it is launched, and as more information becomes available. Concept automobiles, and their derivatives if any, are subject to delays or cancellation by the automaker.

Footnotes[edit | edit source]

  1. "XP" and "SO" were GM designations for experimental (XP) and special order (SO) concept cars.
  2. "Kill order": "GM had a "kill order" on every one of these cars", according to concept car collector/restorer Joseph Bortz. "But the guys who built them would go crying to their bosses and say that these were their Rembrandts, works of art, and could they keep them? And the boss would finally say, 'Okay, but hide the car away. I don't want to hear anything more about it until after I retire'".
  3. A "silver-streak", a body detail peculiar to Pontiacs manufactured from 1935 to 1954, was a five-banded, chromed metal band that ran down the middle of the hood and trunk. Born in the Art Deco style of the mid thirties, it was meant as a visual cue to help distinguish Pontiacs from their competitors, and create the illusion of speed. On the de Mer, and on the Bonneville Special two years prior, a pair were used, which was the first time that two "silver-streaks" running parallel appeared on a Pontiac. In 1957 they were discontinued.
