Chronology
Predecessor Pontiac Bonneville Special

The Pontiac Club de Mer was a purpose-built, experimental car that was built by Pontiac for the General Motors Motorama in 1956 to celebrate General Motors' commitment to futuristic design. The brainchild of GM engineer-designer, Harley Earl (Paul Gillian was also involved being the Pontiac Studio head at the time), 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 reportedly scrapped in 1958.

Only the model exists today, which was owned by Joseph Bortz [3] of Highland Park, IL. until it was sold to noted car collector Ron Pratt at the 2007 Barrett-Jackson Classic Car Auction for $75,000. A running replica based on a 1959 Pontiac chassis was also built by Marty Martino. Taking three years to complete, it sold for $110,000 at the 2009 Barrett-Jackson Auction in Arizona. [4]

Design

Exterior

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 fascia 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" [5] 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 in (990.6 mm). [6]

Interior

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.

Design legacy

The design of the aerodynamic wind screens was carried over to the 1955 and 1956 Corvette race cars. [3] In the years that followed, the model kit maker Revell made a 1/25 scale Club de Mer that actually came with 1950s-clad driver and passenger.

Powertrain

Under the hood lay Pontiac’s brand new V-8 engine, the 287 OHV, 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 (220 kW). 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.

Sloan created LaSalle as a companion marque for Cadillac. LaSalle automobiles were manufactured by Cadillac, but were priced lower than Cadillac-branded automobiles, were smaller, and were marketed as the second-most prestigious marque in the General Motors portfolio. LaSalles were titled as LaSalles, and not as Cadillacs.

The brand was introduced as a limited production performance convertible during the 1957 model year. The Bonneville, and its platform partner, the Grand Ville, are some of the largest Pontiacs ever built; in station wagon body styles they reached just over 230 inches (5.8 m) long, and at 5,000 pounds (2,300 kg) and more were also some of the heaviest cars produced at the time. They were also available as hearses.

Right-hand drive models were locally assembled in Australia, New Zealand, and South Africa until 1969. For most of its run, the Canadian Parisienne was nearly mechanically identical to the American Chevrolet Impala. The Parisienne wagon continued under the Safari nameplate until 1989. Parisienne or La Parisienne means a grammatically female person or thing from Paris, France.

During its 21-year run displacement of the "eight" increased twice as platforms grew. It was superseded by Pontiac's new V8, the 287, in 1955.

Pontiac Safari

The Pontiac Safari is a station wagon that was produced by Pontiac. The Safari name was first applied to Pontiac's version of the 2-door Chevrolet Nomad station wagon. The body style, originally exhibited as a 1954 Chevrolet Corvette Motorama concept car, was shifted to Chevrolet and Pontiac full-size 1955 production vehicles because of the perceived greater sales potential.

The car was easily identified by its chrome star trim along its sides, a feature all Star Chiefs were equipped with.

The Pontiac Banshee is a line of concept cars designed by Pontiac. Beginning in 1964 they assumed the role previously established by General Motors' Firebirds of the 1950s.

Pontiac Chieftain car model

The Pontiac Chieftain is an automobile which was produced by Pontiac from 1949 to 1958. The 1949 Chieftain and Streamliner models were the first all new car designs to come from Pontiac in the post World War II years. Previous cars had been 1942 models with minor revisions.

The H platform, or H-body designates a General Motors front-wheel-drive full-sized automobile platform beginning in 1986. It is related to the C, G and K platforms. Many H-bodies used GM's Buick 3800 V6, and supercharged versions of this engine were available from 1991 to 1999. They originally came in both 2-door and 4-door versions, but the four-door sedans were dramatically more popular, and two-door models were dropped by 1992. Previously, the H platform designation was used for unrelated rear-wheel-drive compact cars.

The GM A platform (1936) was a rear wheel drive automobile platform designation used by General Motors from at least 1936 until 1959, and again from 1964 to 1981.

The car was featured in the promotional short film Design for Dreaming along with the rest of the 1956 General Motors lineup.

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.
