Cadillac History Eldorado 1970

Cadillac History Models & History  1970

The Eldorado (actually Fleetwood Eldorado) for 1970 carried over the 1968 and 1969 body design with an improvement in the engine displacement. The 472 cubic inch engine was bored out to a colossal 500 cubic inches. This was (and still is) the largest passenger-car engine ever built for production. It had 400 horsepower and 550 lbs/ft of torque. The grille included a plaque labeled “8.2 LITRE” to indicate the size of the engine. It was located on the left side of the redesigned grill . The grille itself had a cross-hatched insert, but horizontal blades were set upon it, emphasizing the V-shape of the front. Thinner vertical tail-lamps were used, giving a more rakish look. The winged-V emblems used at the front of the fenders on other Cadillacs were added to the Eldorado front parking lamp lenses. Bright rocker panel trim, with front and rear extensions was used. There was also Eldorado block lettering at the lower front fender behind the wheel housing. A new electric sliding sunroof option was also available. Also the Trackmaster skid control system was made available later in the model year.
