HISTORY OF THE 1955 CADILLAC ELDORADO: 270hp, 331 cu. in. overhead valve V8 engine, two four-barrel carburetors, Hydra-Matic automatic transmission, independent front suspension and live rear axle with semi-elliptic leaf springs, four-wheel hydraulic drum brakes. Wheelbase: 129″ 1955 proved to be a very successful year for Cadillac and car sales were at an all-time high. It was also a particularly important year for the Eldorado, which benefited from a host of improvements. Although styling changes were rather minimal across the board, the Eldorado was the exception, receiving a revised look and a special high-performance engine. At the rear, the traditional Cadillac fishtail fins, in use since 1948, were replaced with sweeping, pointed tailfins a quintessential feature of the spaceflight theme prevalent in the 1950s. Brake, turn signal, and backup lights were positioned at the base of the fins and an Eldorado badge appeared on the rear deck. Additionally, the attractive Eldorado featured full rear wheel cutouts, proudly displaying the new Saber Spoke cast aluminum and steel wheels, offered as standard equipment, replacing the previous chrome wire wheels. Finally, other Eldorado items included metallic appliqués on the upper door and quarter window sills. For 1955, the standard 331 cubic inch V8 engine offered on all Cadillacs produced 250 horsepower, 20 more than the previous model year. The Eldorado, however, benefited from a 270 horsepower version, sporting two four-barrel carburetors an optional high performance setup available for other models as well. Furthermore, Hydra-Matic automatic transmission was standard on all cars and, as expected, an array of comfort and convenience accessories were offered, many of which were standard equipment on the Eldorado Convertible Coupe. The myriad of optional equipment included air conditioning, heating system, new electrically-operated antenna, new signal-seeking pre-selector AM radio, Autronic eye, side-mounted spotlights, fog lamps, E-Z Eye tinted glass, electrically-operated six-way power seats, and a remote control trunk lid, to name but a few.
